5 Ways You’re Screwing Up Your Computer

1.You’re Not Backing Up Continuously

One big way to screw up your computer, and by extension yourself, is to back up in some way that’s not continuous.

This is a LEVEL 10 SCREW UP!

Yes, you should be backing up your data continuously, as in virtually nonstop… all the time… at least once per minute. It sounds excessive, but it’s true.

This is one of the biggest way you’re screwing up your computer (and your smartphone, and your iPad, etc.).

Your data is the most important stuff you own. They’re your irreplaceable photos and videos, your expensive music, your school paper you’ve invested hours and hours in, etc., etc., etc.

While it’s possible to use traditional backup software to back up continuously to an external hard drive or a network drive, it’s easier to get started with, and safer on several levels, to back up continuously with an online backup service.

I’ve reviewed dozens of these online backup services, and take a fresh look at each one again every month. All are great choices and prevent just about any chance of you losing your important stuff.

Backblaze and Carbonite are my favorites, backup non-stop, and both allow unlimited space for surprisingly affordable prices.

So stop screwing up your computer and start continuously backing up to the cloud! Most smartphones have built-in auto-backup capabilities, so be sure to turn those on too!

2.You’re Not Updating Your Antivirus Software

Another “good” way to screw up your computer is to not keep updated that antivirus program you took the time to install.

This is a LEVEL 10 SCREW UP!

Those nefarious malware authors out there make new viruses every day, change how they work, and find new ways of avoiding antivirus software. In response, antivirus software has to respond just as quickly.

In other words, your antivirus software only worked 100% the day you installed it. Kind of depressing, isn’t it?

Most antivirus software, even free antivirus programs (of which there are plenty), automatically update their definitions, the term used to describe the set of instructions the programs use to identify and remove viruses and other malware.

That said, there are sometimes pop-up messages that ask you to do this manually or notices that appear on screen about needing to update the core program before definition updating can continue.

Unfortunately, I see people screw up all the time by closing these… without reading them at all! A message that shows up over and over is usually a good indication that’s it’s important.

So stop screwing up your computer’s ability to fight the bad guys and make sure your antivirus program is updated! Just open the program and look for the “update” button.

If you think you may have been running your computer with a significantly outdated antivirus program, see my How to Scan Your Computer for Malware tutorial for help making sure nothing slipped in while your computer’s defenses were down.

3.You’re Not Patching Software Right Away

Similar to the not-updating-your-antivirus mistake from the last slide, putting off those software updates, especially the operating system ones, is a great way to screw up your computer.

This is a LEVEL 10 SCREW UP!

(I know, three Level 10 screw ups in a row! I’m getting most of the really important stuff out of the way first.)

The majority of software patches these days, especially the ones Microsoft pushes for Windows on Patch Tuesday, correct “security” issues, meaning issues that have been discovered that could allow someone to remotely access your computer!

Once these vulnerabilities in Windows have been discovered, a patch has to be created by the developer (Microsoft) and then installed (by you) on your computer, all before the bad guys figure out how to exploit said vulnerability and start doing damage.

Microsoft’s part of this process takes long enough so the worst thing you can do is extend that window of opportunity any longer by procrastinating on installing these fixes once provided.

Windows Update is probably installing these updates for you automatically but you can check for this, and change the behavior, any time you want. See How Do I Change Windows Update Settings? if you need help.

It’s the exact same situation with your Mac or Linux computer, your tablet, and your smartphone… just different details. However you’re notified that an update is available to iOS, your smartphone software, or your Linux kernel: promptly apply the update!

Other software and app updates are important too and for similar reasons. If your Microsoft Office software, iPad apps, Adobe programs, (etc., etc., etc.) ever ask you to update, just do it.

4.You’re Not Using Strong Passwords

We all use passwords. Most of the devices and services we use require that we do.

What they don’t (usually) require is that the passwords not suck. A “strong” password, in case you didn’t know, is a password that doesn’t suck… in some specific ways.

Hopefully you know that passwords that include your name, simple words, 1234, etc., are all “bad” passwords. Information security experts call these types of passwords weak passwords.

Weak passwords are easy to “crack” with special software. Very weak passwords are even easy enough to guess. Yikes.

This is a LEVEL 9 SCREW UP!

I’ve written about guessing your own simple passwords and even hacking in to your own computer, both things you may be happy to have the ability to do when needed but that every other expert computer user can also do.

See What Makes a Password Weak or Strong if you’re not quite sure how great, or not-so-great, your passwords are. If they don’t meet that “strong” criteria, here’s How to Make a Strong Password.

5.You’re Still Running Windows XP

Windows XP was probably Microsoft’s most successful product of all time, certainly its most successful and popular operating system.

Unfortunately, in April of 2014, Microsoft ended pretty much all support for it, meaning that those important security holes that are patched every month on Patch Tuesday are not being created for Windows XP!

This is a LEVEL 8 SCREW UP!

If you’re still using Windows XP then your computer is still vulnerable to all of the security issues that have been found, and corrected in later versions of Windows, since May of 2014!

This is a Level 8 screw up and not a Level 10 because there are a few ways you can keep yourself relatively safe and still use Windows XP.

How to Use Windows 10’s System Recovery Options

Hardcore Windows users often give their PCs a refresh to improve system performance by reinstalling Windows. Before Windows 8, this was always done with recovery media on a DVD or USB drive, or a small recovery partition that the computer manufacturer included on the PC’s hard drive.

The process was fairly complicated and time consuming. For that reason it was always left in the domain of the power user even though many PCs would benefit from the occasional reset.

With Windows 8, Microsoft finally embraced the trend of PC refreshes, and introduced a formal, easy-to-use procedure to refresh or reset your PC. Microsoft continues to offer those utilities in Windows 10, but the process and options are slightly different compared to its predecessor.

Here’s a look at the reset process for Windows 10 PCs running the Anniversary Update.

Why take such drastic measures?

Giving your PC a fresh start isn’t just for when your PC isn’t running well. Sometimes a virus can trash your whole system. When that happens your PC is really only recoverable after a complete re-installation of Windows.

An official upgrade to Windows 10 that doesn’t play well with your system can also be a problem. Problematic updates in Windows are nothing new; however, since Windows 10 updates are pretty much mandatory there’s a potential for small problems to become widespread more quickly since many people are updating around the same time.

Reset this PC

We’ll start with the easiest process, which is resetting your PC. In Windows 8, Microsoft offered you two options: refresh and reset. Refresh was what you’d do to reinstall Windows without losing any of our personal files. Reset, meanwhile, was a clean installation where everything on the hard drive would be wiped out with a pristine version of Windows remaining.

In Windows 10, the options have simplified a little bit. In this version of Windows “reset” means reinstalling Windows with or without wiping out everything, while the term “refresh” is no longer used.

To reset your PC click on the Start menu, and then select the settings cog icon to open the Settings app. Next, click on Update & security >Recovery.

At the top of the next screen there’s an option labeled “Reset this PC.” Under that heading click Get started. A pop-up window will appear with two options: Keep my files or Remove everything. Choose the option that’s most appropriate and continue.

Next, Windows will take a few moments to prepare and present one final summary screen explaining what will happen. In the case of Keep my files, for example, the screen will say that all apps and desktop programs that aren’t part of the standard installation for Windows 10 will be erased. All settings will also be changed back to their defaults, Windows 10 will be reinstalled, and all personal files will be removed. To continue click Reset and the process will start.

Bad build

When a new build of Windows rolls out (this means a major update) it can sometimes wreak havoc on a small number of systems.

If this happens to you Microsoft has a fall back plan: rolling back to the earlier build of Windows. Microsoft used to give users 30 days to downgrade, but beginning with the Anniversary Update that time limit has been reduced to just 10 days.

That’s not a ton of time to downgrade a system, but for a Windows PC that sees daily use it’s enough time to discover if something’s wrong and roll back. There are many reasons for upgrade problems. Sometimes a specific system configuration (a combination of various computer components) causes a bug that Microsoft didn’t catch in its testing phase. There’s also a chance that a key system component needs a driver update, or the driver was buggy upon release.

Whatever the reason, rolling back is simple. Once again go to Start > Settings > Update & security > Recovery. This time look for the “Go back to an earlier build” sub-heading and then click Get started.

Windows will take a few moments to “get things ready” once again, and then a survey screen will pop-up asking why you are rolling back to the earlier version of Windows. There are several common options to choose from such as your apps and devices aren’t working, earlier builds were more reliable, and an “other reason” box–there’s also a text entry box to provide Microsoft with a fuller explanation of your problems.

Choose the appropriate option and then click Next.

Now here’s the thing. Microsoft really doesn’t want anyone to downgrade since the whole point of Windows 10 is to have as many PC users as possible on the same build of Windows. For that reason, Windows 10 will bother you with a few more screens. First, it will ask if you want to check for updates before downgrading since that might fix the problem. It’s always worth trying that option unless there are special circumstances such as being on day nine of the rollback window and not wanting to risk losing downgrade rights. If you want to see if any updates are available click Check for updates otherwise click No thanks.

Just as with the reset option, there is one last summary screen detailing what will happen. Basically Windows warns that this is like reinstalling Windows and will take some a while to complete during which time the PC will not be usable. Rolling back to an earlier build of Windows can also wipe out some Windows Store apps and desktop programs, and any system settings changes will be lost.

Windows will also admonish you to back up your personal files before downgrading. Personal files shouldn’t be wiped out during a downgrade, but sometimes things go wrong. Thus it’s always a good idea to back-up personal files before any major system software change.

Once you’re ready to go click Next. One last screen warns you that any password changes you’ve made since the upgrade will also be rolled back so be sure to have any previous passwords at the ready or risk getting locked out of your PC. Click Next again, and there will be one last screen where you click Go back to earlier build. The re-installation process will then begin, finally.

It’s a lot of clicking, but rolling back to an older version of Windows is still relatively simple (if mildly annoying) and mostly automated.

Uninstall a smaller update

This feature isn’t quite the same as the reset options in Windows 10, but it is related. Sometimes problems begin on a system after one of Microsoft’s small, regular updates is installed.

When these updates cause problems you can uninstall them by going to Start > Settings > Update & security > Windows Update. At the top of the window click the blue Update history link, and then on the next screen click another blue link labeled Uninstall updates.

This opens a control panel window with all your recent updates listed. Click on the most recent ones (they usually have a “KB number”), and then click Uninstall at the top of the list.

That will uninstall the update, but unfortunately based on how Windows 10 updates work the problematic update will try to reinstall itself pretty soon thereafter. That’s definitely not what you want. To overcome this problem, download Microsoft’s troubleshooter for hiding updates to prevent the update from installing automatically.

Advanced moves

There’s one final option under Settings > Update & security > Recovery that’s worth knowing about called “Advanced startup.” This is how you can start the traditional method of re-installing Windows using a DVD or USB drive. Unless you purchased Windows 10 at a retail store, you’ll have to create your own installation media using Microsoft’s Windows 10 media creation tool.

Once you have installation media ready to go and inserted into your system, click Restart now. You’ll then land on the usual Windows installation screens when installing from a DVD or USB drive.

Really, you should only need the advanced option if other methods of resetting or reinstalling Windows 10 fail. It’s rare, but there may be situations where the reset option doesn’t work or the rollback option is no longer available. That’s when reinstalling from a USB can come in handy; however, keep in mind that if you’re creating fresh Windows 10 installation media from Microsoft’s website it will likely be the same build as the one you’ve got installed. That said, sometimes reinstalling the same version of Windows from a fresh install disc can fix the problem.

Final thoughts

Using Windows 10’s recovery options are handy when your PC is in a dire situation, but it’s also quite a drastic solution. Before trying a reset or rolling back to a previous build, do some basic troubleshooting.

Does rebooting your PC fix the problem, for example? Did you install any new programs or apps recently? Try uninstalling them. It’s surprising how often a third-party program can be at the root of your issue. Finally, check to see if all your component drivers are up to date, and check for any new system updates that might fix the problem via Windows Update.

You’d be surprised how many times a simple reboot or an update can fix what seems like a catastrophic issue. If basic troubleshooting doesn’t work, however, there’s always the Windows 10 reset option ready and waiting.

4G Mobile Networks: The Pros and the Cons

Although 3G mobile networks hogged the limelight in the past, once 4G mobile networks made their grand entry, the former was all but forgotten. Offering amazing speed and efficiency, this technology took the mobile market by storm.

Internet connectivity on mobile devices is now more of a necessity than a luxury. More and more mobile device users are constantly using their gadgets to connect to the Internet and stay online for very long periods of time.

Considering this scenario, the latest 4G mobile network seems to be the answer for every mobile device owner. However, 4G connectivity is not without its downsides.

In this article, we discuss the pros and cons of 4G mobile networks.

Pros of 4G Mobile Networks

  • The most obvious advantage of the 4G mobile network is its amazing speed. Increased bandwidth leads to much faster data transfer speed, which is especially advantageous for mobile devices. Users of the 4G network get the advantage of superior, uninterrupted connectivity, especially for advanced tasks such as video chats and conferences. Considering the younger generation of mobile device users, they can stream music, ​videos and movies at a much faster rate than ever before and can also easily share information online.
  • 4G networks offer much more coverage than other systems such as WiFi, which forces users to depend upon hotspots in each area you visit. Since 4G offers a coverage of 30 miles and more, as also overlapping network ranges, users would be assured of complete connectivity at all times.
  • One of the biggest problems with WiFi networks is that of online security. This is especially true for mobile devices. 4G networks offer complete privacy, security and safety. This is especially beneficial for corporate establishments and business persons, who hold sensitive information on their respective mobile devices.

4G networks are quite affordable these days, what with pricing schemes being considerably slashed to fit users’ budgets. Of course, this type of connectivity is more expensive than traditional WiFi networks, but it also has a lot more advantages to offer to users.

  • This network also offers users several options to choose from, as regards plans and equipment to connect to the 4G network. Many mobile carriers also offer special introductory offers for new customers, which works out to be very reasonable for them.

Cons of 4G Mobile Networks

  • Though the concept of 4G mobile networks is steadily gaining popularity, connectivity is still limited to certain specified carriers and regions. Of course, the number of cities that have 4G coverage is increasing by the day. However, it would take its own time for this network to be available in all the major cities of the world.
  • Though the hardware compatible with 4G networks is available at much cheaper rates today than earlier, the fact remains that this new equipment would necessarily have to be installed in order to supply these services. This would prove to be a cumbersome process for most mobile carriers planning to launch these services.
  • Since 4G mobile technology is still fairly new, it will most likely have its initial glitches and bugs, which could be quite annoying for the user. Needless to say, these teething troubles would be sorted out in due course of time, as well as with an increase in network coverage.
  • 4G mobile networks use multiple antennae and transmitters and hence, users would experience much poorer battery life on their mobile devices, while on this network. This would mean that they would have to use larger mobile devices with more battery power, in order to be able to stay online for longer periods of time.
  • Users would be forced to make do with 3G or WiFi connectivity in the areas that do not yet have 4G mobile network coverage. While this is a problem in itself, the worse issue is that they would still have to pay the same amount as specified by the 4G network plan. This loophole has already resulted in many disgruntled customers. This situation can only be resolved once mobile carriers expand their 4G network coverage to include more regions.

In Conclusion

4G mobile networks, though advantageous, also comes with its disadvantages. While this technology is evolving speedily, it would still take its time to emerge as the most popular network. Mobile carriers and users interested in investing in 4G would do well to analyze and understand its pros and cons before adopting in this new technology.

International Power Adapters: What You Need to Know

If you’re planning on traveling internationally, finding a power adapter should be as simple as looking up the plug standard for your destination, buying an adapter, and packing your suitcase.

However, if you need more than just a plug adapter, you could accidentally ruin your hair dryer.

First, let’s explore why we have so many different plugs and standards across countries and then let’s look at how to check your label and reduce the risk of accidentally buying the wrong adapter or forgetting a necessary converter.

There are a few key variations in standards between countries (or sometimes even within a country):

  • Ÿ Current
  • Ÿ Voltage
  • Ÿ Frequency
  • Ÿ Outlet and Plug shape

Current

The two main standards for current are AC and DC or Alternating Current and Direct Current. In the US, we developed a standard during the famous war between Tesla and Edison. Edison favored DC, and Tesla AC. The big advantage to AC is that it was capable of traveling greater distances between power stations, and in the end, it was the standard that won out in the USA.

However, not all countries adopted AC. Neither did all yoru devices. Batteries and the internal workings of many electronics also use DC power. In the case of laptops, the large external power brick is actually converting AC power to DC.

Voltage

Voltage is the force with which electricity travels. It’s often described using a water pressure analogy. Although there are several standards, the most common voltage standards for travelers are 110/120V (USA) and 220/240V (most of Europe).

If your electronics are only meant to handle 110V of force, having 220V shooting through them could be catastrophic.

Frequency

Frequency for AC power is how often the current alternates each second. In most cases, the standards are 60Hz (America) and 50Hz everywhere that values the metric system. In most cases, this isn’t going to make a difference in performance, but it can occasionally cause problems with devices that use timers.

Outlet and Plug Shapes: A, B, C, or D?

Although there are a lot of different plug shapes, most travel adapters settle for the four most common. The International Trade Administration breaks these down into alphabetical shapes (A, B, C, D and so on) so you can check to see if you need something beyond the usual four for your travels.

Can You Just Use a Power Plug Adapter?

Is that all you would need? You can buy USB adapters and use your USB C cord with a USB A plug. It seems like the same concept should apply.

For many devices, it is that simple. Look at the back of your device where you find the UL listing and other information about your device. In the case of laptops, you’ll locate the information on your power adapter.

The UL listing will tell you the frequency, current, and voltage that your device can handle. If you’re traveling to a country compatible with those standards, you just need to find the right shape of plug.

Devices generally come in three types: those that only comply with one standard, dual mode devices that comply with two standards (switching between 110V and 220V), and those compatible with a wide range of standards. You may need to flip a switch or move a slider in order to convert devices with dual modes.

Do You Need an Adapter or Converter?

Now, should you want to travel with a single voltage device to a country with different voltage, you’ll need a voltage converter. If you travel someplace from a lower voltage (USA) to a higher voltage (Germany), it will be a step-up converter, and if you travel in the opposite direction, it will be a step-down converter. This is the only time you should use a converter, and remember that you don’t need to use them with your laptop. In fact, you might damage your laptop if you do.

In rare cases, you may also need an AC converter to convert DC power to AC or vice versa, but again, your laptop uses DC power already, so do not use a third-party converter with it.

Check with the company that made your laptop to see what you need. If necessary, you may also be able to buy a compatible power adapter in your destination country.

Hotels

It should be noted that many international hotels have built-in wiring for their guests that don’t require any special adapters or converters to use. Ask before your trip to see what your accommodations offer.

What About Tablets, Phones, and Other USB-Charging Devices?

The good news about USB-charging devices is that you don’t need a plug adapter. In fact, using one would probably ruin your charger. You just need to buy a compatible charger. USB is standardized. Your charger is doing all the work to convert the voltage to the USB charging standard to power your phone.

In fact, USB may be our best hope for standardizing our power charging for the future, between that and wireless charging systems, we may be moving toward the next “electric plug” solution for our international travel.

Although the USB standard has changed over time 1.1 to 2.0 to 3.0 and 3.1, it has done so in a thoughtful way that offers legacy compatibility. You can still plug your USB 2.0 powered device into a USB 3.0 port and charge it. You just don’t see the bandwidth and speed advantages when you do. It’s also easier to replace and upgrade USB ports over time than it is to rewire homes for new electrical standards.

Why do Countries Have Different Shaped Power Outlets?

After a system of power transmission was established (AC vs DC), homes were wired for electricity, but there was no such thing as a power outlet. There wasn’t a good way to patch something into the network temporarily. Devices were wired into the home’s electrical network directly. We still do this with some appliances, like light fixtures and oven hoods, but at the time, it meant there was no such thing as a portable electronic device.

As countries built out electrical systems, there wasn’t need to think about compatibility. It was a wonder that power even standardized between cities and states within a single country. (Actually, that didn’t always happen within countries. Brazil still has incompatible systems within portions of the country according to the International Trade Administration.)

That also meant different countries settled around different voltages and frequencies as power plants were built. Tesla recommended 60 Hz in the US, while Europeans went with the more metrically-compatible 50 Hz. The US went to 120 volts, while Germany settled on 240/400, a standard later adopted by other Europeans.

Now that countries were establishing their standards for transmitting power and houses were getting wired to receive it, an American inventor named Harvey Hubbell II came up with the idea to let people plug their devices into light sockets. You can still buy power adapters you can plug into light sockets today. Hubbell eventually improved the concept to create what we now know of as the American outlet plug with two prongs.

A few years later, someone else upgraded the two prong plug to add a third, grounding prong, which makes the socket a little safer and less likely to shock you when you plug things into it. American outlets also grew two different sized prongs to keep people from accidentally plugging them in the wrong way.

Meanwhile, other countries began developing outlets and plugs without considering compatibility, although it was the outlet that made portable electronics possible. It was just a matter of which standard gained traction in each location. Most country systems also adapted a system that made it only possible to plug your devices in one way, whether it was by making the plugs different shapes, making three of them, or putting them at different angles.

Finger Scanners: What They Are And Why They Are Gaining in Popularity

A fingerprint scanner is a type of electronic security system that uses fingerprints for biometric authentication to grant user access to information or to approve transactions.

It used to be that fingerprint scanners were mostly seen in movies and TV shows, or read about in science fiction novels. But such times of imagination surpassing human engineering ability has been long gone – fingerprint scanners have been in use for decades!

Not only are fingerprint scanners becoming more commonplace in the latest mobile devices, but they’re gradually making headway into everyday life. Here’s what you should know about fingerprint scanners and how they work.

What Are Fingerprint Scanners (a.k.a. Finger Scanners)?

Human fingerprints are practically unique, which is why they’re successful at identifying individuals. It’s not just law enforcement agencies that collect and maintain databases of fingerprints. Many types of occupations that require professional licensing or certification (e.g. financial advisors, stock brokers, real estate agents, teachers, doctors/nurses, security, contractors, etc.) mandate fingerprinting as a condition of employment. It’s also typical to provide fingerprints when having documents notarized.

Advancements in technology have been able to incorporate fingerprint scanners (can also be referred to as ‘readers’ or ‘sensors’) as another (optional) security feature for mobile devices.

Fingerprint scanners are one of the latest in an ever-growing list – pin codes, pattern codes, passwords, face recognition, location detection, iris scanning, voice recognition, trusted Bluetooth/NFC connection – of ways to lock and unlock smartphones. Why use a fingerprint scanner? Many enjoy it for the security, convenience, and futuristic feel.

Fingerprint scanners work by capturing the pattern of ridges and valleys on a finger. The information is then processed by the device’s pattern analysis/matching software, which compares it to the list of registered fingerprints on file. A successful match means that an identity has been verified, thereby granting access. The method of capturing fingerprint data depends on the type of scanner being used:

  • Ÿ Optical Sensor: These types of scanners basically make a photocopy of the finger. Many illuminate the finger in order to deliver crisp contrast of lines as the light-sensitive scanner (usually an image sensor or light-sensitive microchip) records the information to produce a digital image. Many PC-connected fingerprint scanners use optical sensors.
  • Ÿ Capacitive Sensor: Instead of light, capacitive scanners use electricity (think of the way touchscreens work) to determine fingerprint patterns. As a finger rests on the touch-capacitive surface, the device measures the charge; ridges exhibit a change in capacitance, while valleys produce practically no change at all. The sensor uses all this data to accurately map out prints. Most all smartphones with fingerprint scanners use capacitive sensors.
  • Ÿ Ultrasonic Sensor: Similar to how bats and dolphins use echolocation to find and identify objects, ultrasonic scanners work via sound waves. The hardware is designed to send out ultrasonic pulses and measure how much bounces back. Ridges and valleys reflect sound differently, which is how ultrasonic scanners are able to create a detailed 3D map of fingerprint patterns. Ultrasonic sensors are currently being prototyped (e.g. by Qualcomm Technologies, Inc.) and tested for use in mobile devices

Fingerprint Analysis

You might be staring at your fingertips right now, wondering just how scanners can so quickly determine a match or not.

Decades of work have led to the classification of fingerprint minutiae – the elements that make our fingerprints unique. Although there are over a hundred different characteristics that come into play, fingerprint analysis basically boils down to plotting the points of where ridges end abruptly and fork into two branches (and the direction).

Combine that information with the orientation of general fingerprint patterns – arches, loops, and whorls – and you have a pretty reliable way of identifying individuals. Fingerprint scanners incorporate all of these data points into templates, which are used whenever biometric authentication is required. More data collected helps to ensure greater accuracy (and speed) when comparing different sets of prints.

Fingerprint Scanners in Everyday Life

The Motorola Atrix was the first smartphone to incorporate a fingerprint scanner, way back in 2011. Since then, many more smartphones have incorporated this technological feature. Examples include (but are not limited to) the: Apple iPhone 5S, Apple iPad models, Apple iPhone 7, Samsung Galaxy S5, Huawei Honor 6X, Huawei Honor 8 PRO, OnePlus 3T, OnePlus 5, and Google Pixel. It’s likely that more mobile devices will support fingerprint scanners as time goes on, especially since you can already find fingerprint scanners in many everyday objects.

When it comes to PC security, there are plenty of fingerprint-scanning options, some of which can be found already integrated into certain laptop models. Most of the readers you can purchase separately connect with a USB cable and are compatible with both desktop and laptop system (typically Windows OS, but also macOS). Some readers are closer in shape and size to that of USB flash drives – in fact, some USB flash drives have a built-in fingerprint scanner to grant access to the data stored inside!

You can find biometric door locks that use fingerprint scanners in addition to touchscreen/keypads for manual entry. Biometric car starter kits, installed in vehicles as an aftermarket accessory, use fingerprint scanners to add another layer of security. There’s fingerprint-scanning padlocks and safes, too. And if you ever plan a trip to Universal Studios, you can rent a free storage locker that uses fingerprints instead of physical keys or cards. Other theme parks, such as Walt Disney World, scan fingerprints upon entry in order to combat ticket fraud.

More Popular Than Ever (Despite Concerns)

The application of biometrics in everyday life is expected to grow as manufacturers devise new (and more affordable) ways to incorporate the technology. If you own an iPhone or iPad, you may have already been having helpful conversations with Siri. The Amazon Echo speaker also employs voice recognition software, offering a host of useful skills through Alexa. Other speakers, such as the Ultimate Ears Boom 2 and Megaboom, have integrated Alexa voice recognition through firmware updates. All of these examples use biometrics in the form of voice recognition.

It should come as little surprise to find more products designed to interact with our prints, voices, eyes, faces, and body with each passing year. Modern fitness trackers can already monitor heartbeat, blood pressure, sleep patterns, and movement in general. It will only be a matter of time until fitness tracker hardware is precise enough to identify individuals through biometrics.

The subject of using fingerprints for biometric authentication is hotly debated, with people arguing the dire risks and significant benefits in equal measure. So before you start using the latest smartphone with a fingerprint scanner, you might want to weigh some options.

Pros of Using Fingerprint Scanners:

  • Ÿ Allows fast and easy one-finger access to unlock devices
  • Ÿ Excellent way to identify unique individuals
  • Ÿ Extremely difficult to fake/duplicate (versus identification/access cards, etc.)
  • Ÿ Practically impossible to guess/hack (versus pin codes, passwords, etc.)
  • Ÿ You can’t forget your fingerprint (as you might with passwords, codes, patterns, access cards, etc.)

Cons of Using Fingerprint Scanners:

  • Ÿ Not completely foolproof (individuals with the right resources, time, and dedication can trick scanners with forgeries and/or master prints)
  • Ÿ Can’t get new prints (you can change/replace cards, codes, and passwords, but there’s not much you can do if someone steals your fingerprint data)
  • Ÿ Encryption is still questionable (the safety of your fingerprint data hinges on the software/hardware manufacturer)
  • Ÿ Finger injuries can impede successful scanning and deny access to authorized users (even slight imperfections can create difficulties)
  • Ÿ Germs (know how many people touched that public scanner before you did? Better sanitize it first)

The utilization of fingerprint scanners in consumer-level electronics is still quite new, so we can expect standards and protocols to be established over time. As the technology matures, manufacturers will be able to fine-tune and improve the quality of encryption and data security in order to prevent possible identity theft or misuse with stolen fingerprints.

Despite the concerns associated with fingerprints scanners, many find it preferable to entering in codes or patterns. The ease of use actually results in making more mobile devices secure overall, since people would rather swipe a finger to unlock a smartphone than remember and tap out a code. As for the fear of criminals cutting off fingers of everyday individuals in order to gain access, it’s more Hollywood and (irrational) media hype than reality. Greater worries tend to revolve around being accidentally locked out of your own device.

Locked Out Using a Fingerprint Scanner

Even though fingerprint scanners tend to be quite accurate, there can be a number of reasons why one won’t authorize your print. You’ve likely tried to get back into your phone while doing dishes and found that wet fingers typically can’t be read by the sensors. Sometimes it’s a weird glitch. Most manufacturers have anticipated this happening from time to time, which is why devices can still be unlocked by passwords, pin codes, or pattern codes. These are typically established when a device is first being set up. So if a finger won’t scan, simply use one of the other unlocking methods.

If you happen to forget a device code in a fit of anxiety, you can remotely reset (Android) lock screen passwords and pins. As long as you have access to your main account (e.g. Google for Android devices, Microsoft for desktop/PC systems, Apple ID for iOS devices), there is a way to log in and reset the password and/or fingerprint scanner. Having multiple means of access as well as two-factor authentication can improve your personal security as well as save you in such forgetful situations.

10 easy ways to speed up Windows 10

If your formerly shiny, new Windows 10 PC has begun to lose some of its luster, there are ways to put a little pep back in its step. Here are some quick, easy ways to improve its performance without swapping out any hardware.

  1. Go opaque

Windows 10’s new Start menu is sexy and see-through, but that transparency will cost you some (slight) resources. To reclaim those resources, you can disable transparency in the Start menu, taskbar, and action center: Open the Settings menu and go to Personalization > Colors and toggle off Make Start, taskbar, and action center transparent.

  1. No special effects

Making the Start menu, taskbar, and action center transparent is one thing, but Windows 10 still has a lot of other snazzy, built-in special effects. To really go bare-bones on the special effects, right-click the Start button and click System.

Click Advanced system settings to open the System Properties menu. On the Advanced tab under Performance, click Settings…

This will open the Performance Options menu. In the Visual Effects tab, either choose Adjust for best performance to turn off all unnecessary animations and special effects, or choose Custom: and deselect the visual effects you think can live without. When you’re finished, click OK to apply your changes.

  1. Disable Startup programs

If your PC is taking a long time to boot up — and you’ve enabled Fast Startup and everything — you may have too many programs starting up when you turn your computer on. To fix this, right-click on the Start button and click Task Manager. Click the Startup tab (click More details if you don’t see the Startup tab) and peruse the list of programs that start up with your computer. If you see a program that doesn’t need to be there, right-click it and click Disable. You can also arrange the list of programs by Startup impact, if you’d like to see the programs that are taking up the most resources (and time).

  1. Find (and fix) the problem

Windows 10 has a built-in performance troubleshooter that can help you find and fix any problems that might be affecting your PC’s speed. To open the troubleshooter, right-click on the Start button and click Control Panel. Under Security and Maintenance at the top, click Troubleshoot common computer problems. Next, under System and Security, click Run maintenance tasks.

  1. Reduce the Boot Menu Time-out

When your computer starts up, the boot menu is displayed for a certain amount of time before the operating system loads. This gives you time to do things like start Windows in Safe Mode. You can shave a few seconds off your startup time by changing the boot menu time-out, which is set to 30 seconds by default.

To do this, right-click on the Start button and click Control Panel. Go to System > Advanced system settings, and, under Startup and Recovery, click Settings.

Next to Time to display list of operating systems:, change the value from 30 seconds to 10 seconds and click OK.

  1. No tipping

In an effort to be helpful, Windows 10 will sometimes give you tips on how to get the most out of the OS. It scans your computer in order to do this, a process that can have a slight impact on performance. To turn off these tips, go to Start > Settings > System > Notifications & actions and toggle off Get tips, tricks and suggestions as you use Windows.

  1. Run Disk Cleanup

This one’s a win-win. It’ll improve performance and free up space on your hard drive. Disk Cleanup has been around forever, but this trusted Windows utility can still help clean out the temporary files, installers and other junk littering your hard drive. To run it, just search for Disk Cleanup, run it and click the button labeled Clean up system files.

  1. Eradicate bloatware

If your PC came with preinstalled apps you don’t want or need, get rid of them. Same goes for any apps you installed that you later found to be of little or no use. Right-click the Start menu, choose Control Panel and under the Programs header, click Uninstall a program. Peruse the list from time to time and select the programs you no longer need and click Uninstall at the top of the list.

  1. Power plan

Make sure you aren’t using a Power saver plan if you don’t need to. Even desktops will sometimes feature a power-saver option, which doesn’t do you any good unless you are trying to conserve battery life. Open the Control Panel and go to Hardware and Sound > Power Options to see which power plan you are currently using. For better performance, make sure you are using a High Performance or Balanced plan (or a plan from the PC manufacturer that says it’s balanced).

  1. Restart your PC

Is speeding up your computer as simple as…restarting it? Maybe. Restarting your PC clears out its memory and stops any processes that might be taking up resources. Also, shutting down your computer is not the same as restarting it — shutdown is affected by Windows 10’s Fast Startup, which saves a snapshot of your PC and its processes in a hiberfile for faster boot-up. Restart is not affected by Fast Startup, so if you have Fast Startup enabled, restarting your PC is the only way to fully clear the memory and shutdown processes.

How to Restore a Dead or Dying Laptop Battery

Laptop batteries are expensive pieces of equipment, so if you have an old laptop that still works fine, who wants to shell out upwards of $100 to replace the battery right!? Luckily, there are a lot of ways, some technical, some interesting and some strange ones, that people have come up with to restore dying batteries on laptops.

In this article, I’m going to try to list out all the different ones I’ve read about and if I can remember where I read it, I’ll link back to the original source. If you have tried to restore a laptop battery yourself, let us know your method in the comments.

Method 1 – The Freezing Method

I once saw a movie where a guys’ phone was about to die, so he took out the battery and stuck in some snow, which apparently made it last longer! I still don’t know if that’s true or not, but apparently you can freeze a laptop battery and get more juice out of it. Here’s the procedure very succinctly:

Step 1: Take your battery out and place it in a sealed Ziploc or plastic bag.

Step 2: Go ahead and put the bag into your freezer and leave it there for about 12 hours. Some people suggest leaving it for longer, but I wouldn’t leave it for more than 24 hours.

Step 3: Once you take it out, remove the plastic bag and let the battery warm up until it reaches room temperature. Be sure to wrap it in a towel and wipe away any condensation as it warms up.

Step 4: Reinsert the laptop battery and charge it completely.

Step 5: Once charged, unplug the power and let the battery drain all the way down.

Now repeat steps 4 and 5 at least 4 times: charge all the way to full, then discharge completely. That should be it! Unless your battery is leaking acid, you should get some kind of bump in the battery life.

Note that you should only perform this on NiCD or NiMH batteries. If you try this on a lithium battery, it’ll make the battery life worse. Unfortunately, there is no way to restore a lithium battery. You’ll have to find your laptop specs to see what kind of battery you have. For lithium ion batteries, you can’t restore, but you can possibly extend the life of a battery. Read method 2.

Method 2 – Cool Your Computer

If you have a lithium ion based battery, you can increase it’s life by making sure your laptop is cool. If you have a laptop that gets really hot, it can damage the battery and cause the shortness in battery life. I have an old Sony VAIO laptop and I saw a significant increase in laptop battery life when I bought a laptop cooling pad off Amazon. You can get one like this for $20.

You may think your battery is on it’s last leg, but it could simply be that it’s getting too warm and therefore loses charge faster.

Method 3 – Recalibrate Your Battery

With most newer batteries, this is no longer necessary, but if your battery is dying, then it’s probably a pretty old battery. In that case, you may benefit from a recalibration. Recalibrating a battery is done because sometimes the operating system cannot figure out how much capacity is left in the battery. This can happen if the laptop is always plugged in or if the battery was never let to die all the way.

You can tell whether your battery needs calibration if your battery never charges to 100% (say only to 95%) or if the OS says you have 35 min of battery remaining, but the computer dies either much sooner or much later. A lot of manufacturers have released calibration tools for specific laptop models, so first perform a Google search with your computer model + battery calibration.

If you have to manually recalibrate a battery, the procedure is pretty straight-forward:

Step 1: Charge your battery to 100% or to whatever max percentage it can reach and leave it there for about 2 hours to cool down.

Step 2: Now disconnect the power and let the battery drain. There seems to be two views about how to do this. You can either let the battery run down all the way until the laptop dies or you can set it so that it goes to sleep or hibernates around 3 to 5%. Either way, you want to make sure the display stays on until it either dies or goes to sleep.

Step 3: Let the computer remain turned off for anywhere between 3 to 5 hours.

Step 4: Turn it back on and let it charge all the way to 100%.

That’s pretty much it. Now the computer should be giving you a more accurate reading of the actual capacity of the battery.

Method 4 – Remove Battery When Plugged In

If you have a laptop with a removable battery, you can try to remove the battery during the times you have it plugged into the wall. You may have to test this because some laptops don’t work properly with the battery removed. However, if the laptop is running fine and it’s connected to a power source all the time, it may help to simply remove the battery.

The chemical reactions will continue to occur in the battery regardless of whether or not it’s in the laptop, but it could increase the life of the battery. Since the battery is cool and not hot when plugged in, you’ll get more life out of your battery.

Of course, you’ll need to make sure you’re not living in an area where the power goes out because your computer will die immediately and you’ll lose any data. This method is also time-consuming and annoying and something most people won’t do. The last method below may be the best.

Method 5 – Unplug at Full Battery

The last option you can try is to let the battery charge to 100% and then simply unplug the computer. When it gets close to dying, i.e. less than 5%, go ahead and plug it in and let it charge up. However, this could reduce battery life on newer lithium ion batteries, so for those batteries it’s suggested you only let the battery level drop to 35% to 45% and then charge it back up to 75% to 85%. Sounds crazy, but apparently that will give you the best battery life because it won’t use up as many charge and recharge cycles.

Make your laptop battery last all day

We’re all at the mercy of the battery packs inside our smartphones and laptops. Once these batteries die, our lives get put on hold until we can find somewhere to plug in again. So battery life estimates are one of the first specs a lot of us look for when choosing a new device.

You don’t want to spend all day worrying about when you’ll next be able to charge up your laptop, so take some proactive action to limit the drain on its battery. With the right operating system tweaks and customizations, plus some good habits, you can go longer than ever without being shackled to a wall outlet.

Adjust screen settings

One of the biggest draws on your laptop’s battery is that bright, high-resolution display. Anything you do to ease that strain will have a beneficial effect on the length of your battery’s life.

Start with brightness: Dial down the brightness of the screen as much as you can without straining your eyes, using whatever keyboard shortcuts your laptop offers. You can make more detailed modifications by opening up System then Display in Windows Settings or Displays in System Preferences on macOS.

In addition, screens that time out sooner use up less battery life. To set this, and a bunch of other power-saving options, choose Power & sleep inside the System section of Settings on Windows or Energy Saver from System Preferences on macOS.

The other settings available on the same screens let you put the hard drives to “sleep” (which means they take longer to wake back up, but use less power), put USB devices into a low power mode, and more. These tweaks won’t make a major difference, but you can eke out some extra battery life by enabling them. If you’re on Windows, there’s a special Battery saver mode available which maximizes the time you get between battery charges. To find it, click the battery icon on the taskbar.

Reduce your workload

The harder your laptop is working, the faster your battery will drain. Which is why, when you’re away from a power source, you should close down any programs hanging around in the background that you’re not actually using. If your laptop runs fewer applications, and avoids demanding programs (think games and video editors), its battery should take longer to drain.

Meanwhile, the browser is a bigger battery sucker than you might think. Resist the temptation to have dozens of browser tabs open at once, and your laptop’s battery will thank you. And when you’re browsing, avoid video streaming sites. They typically demand a lot of battery life, both because they keep the screen constantly active, and because they require a decent amount of processing power.

Audio makes a difference too. Active speakers blaring out music will use up more battery power than silence—or a pair of plugged-in headphones. If you can, turn down the volume or do without the sound altogether.

Maintaining Wi-Fi and Bluetooth connections also uses up battery power, albeit a pretty small amount. If you can disconnect your laptop and work offline—and do without a wireless mouse and other peripherals—you’ll get a little bit more battery life as a result. We’re not talking major improvements, but you might just make it to the end of the day.

Keep that battery healthy

Lithium-ion batteries degrade naturally over time, but treat your laptop battery right, and you’ll enjoy better battery life for longer. Avoiding environments that are too hot or too cold is a good start, as batteries don’t like temperature extremes, which wear them down more quickly.

Demanding applications on your computer can generate that heat your battery needs to avoid. Which brings us back to the idea of sticking to lightweight tasks and programs while you’re away from a power source. If you really have to have a gaming session or encode some video, consider using a laptop cooler to dissipate the heat more effectively, and keep your laptop battery running for longer.

There’s an ongoing debate within tech circles over the “healthiest” approach to recharging batteries. The most up-to-date advice suggests that shallow discharges and recharges are preferable in the long-term, rather than allowing your battery to drain completely each time—although you should still do a full discharge about once a month. Unplugging your laptop once it’s fully charged, rather than leaving it always plugged in, tends to be better for your battery’s health as well.

Finally, if you won’t be using your laptop for a while, Apple and others recommend leaving the battery with a 50 percent charge in it—leaving it fully charged or fully discharged for an extended period of time can permanently damage it.

What the Coming USB 3.2 Standard Means for You

Just when you thought you could chitchat with authority about USB standards at your next dinner party, a new one comes along to shake everything up again. The latest USB 3.2 standard is going to be confirmed in September, and here’s what that means for your laptop, your phone, and those new USB-C cables you just went out and bought.

A very brief history of USB

USB, or Universal Serial Bus, is an agreed-upon standard that makes sure if you buy kit with USB technology built in, then it’s all going to work happily together. While we have a certain amount of dongle hell to deal with today, it’s nothing compared to the early 90s, when computer peripherals used all kinds of weird and wonderful connectors, and it took at least half a morning to install and configure your latest purchase.

The big computing beasts Compaq, DEC, IBM, Intel, Microsoft, NEC, and Nortel started work on the USB standard in 1994, with the original USB 1.0 specification arriving in January 1996, with its blazing standard speed of 1.5 Mbit/s.

USB 2.0 followed in April 2000, ramping up speeds to 480 Mbit/s—not all that important for a joystick but invaluable for an external hard drive. Another significant upgrade arrived in November 2008 with USB 3.0, upping the potential data transfer rates again to 5 Gbps while keeping backwards compatibility with USB 2.0 gear. If you have the latest USB 3.1 installed today, then you have the potential for up to 10 Gbps of data transfer, even if most consumer peripherals don’t get close to that. There’s also support for providing 100W of power, which is why laptops can now be charged via USB.

Cords, plugs, and data

The USB standards as set out by the USB Implementers Forum (USB-IF) cover a host of technologies: Not just the protocols for shifting data, but also the cables you can use, and the connectors on the end of those cables. The USB-C port we’ve been hearing so much about lately is linked to, but technically separate from, the USB standards for data transfer. It was also developed by the USB-IF, and it was announced around the same time as USB 3.1, but it also works with USB 2.0 cables and gear.

In other words, just because your cable has a USB-C connector on the end doesn’t necessarily mean you’re getting the goodness of USB 3.1. Obviously it’s easier to develop connectors and cables alongside data protocols—USB-C is specifically designed to take advantage of the benefits of USB 3.1, benefits like carrying enough power to charge laptops—but they’re actually two separate standards, albeit closely related. Cables using the familiar, flat USB-A connectors can still have USB 3.1 inside (look for the turquoise coloring as an easy way to check).

USB-C has been designed as the port and connector of the future, one that will work with everything from phones to laptops (and work both ways up as well, as an added bonus). We’re not there yet, but over the next couple of years USB-C and USB 3.1 will become the standard on electronics gear, at least until the next spec rolls around…

The USB 3.2 standard

USB 3.2 is (as the name suggests) the next step up from USB 3.1, though it won’t be appearing in your local Best Buy any time soon—it’s only just been announced by the USB-IF, and its headline feature is its support for what’s called multi-lane operation, where two lanes of 5 Gbps or 10 Gbps can run together in tandem by utilizing extra wires inside USB cables. The theoretical maximum transfer rate therefore gets bumped up to 20 Gbps.

Apart from that pretty significant speed boost, the USB 3.2 spec is a relatively minor upgrade, which might be why it only gets an extra 0.1 on the number count. It will of course work with USB-C connectors, and in most cases you won’t have to upgrade your cables if your laptop or phone uses USB 3.2 (more on this below).

The USB 3.2 spec is expected to be finalized in September but how soon we start seeing in consumer electronics depends on a number of factors, including market trends, manufacturing schedules, and profit margins. At least having just a minor upgrade this time around means the USB ports on our gadgets won’t need to be significantly retooled to get the standard supported.

Future-proofing your USB buying

The good news for us humble consumers is that older USB standards tend to stick around for a long time, and newer standards are often backwards compatible—new cables will work with old computers and phones, just with some of the performance perks dialled down. To put it another way, you don’t necessarily have to upgrade your microUSB smartphone just to get on the USB-C bandwagon, because microUSB is going to be supported for a long time yet.

That said, if you want to future-proof your purchases and make sure they’re going to work with all of the other shiny new gear coming out this year and next, look for devices and cables that come with the top-end combination of USB 3.1 and USB-C connectors. You might not get blazing speeds when you connect them up to older equipment, but they’ll be ready for the next wave of hardware that comes along.

The bump to USB 3.2 means some existing cables will potentially be able to double their data transfer rates. If you’re using USB 3.0 or USB 3.1 cables with USB-C connectors, they’ll be able to send twice as much data—either 2 x 5 Gbps or 2 x 10 Gbps—thanks to the multi-lane technology in USB 3.2. You’ll need equipment that supports the new USB 3.2 standard at each end of the cables, but the cables themselves don’t need to be replaced to get the extra speeds.

The Phone Repairs You Probably Shouldn’t Try At Home

Having a broken phone is not a situation you want to be in for long but there’s always the question of whether to stump up the cash for a professional repair or have a go at fixing it yourself (assuming you’ve no insurance or warranty coverage). This should be your guide for deciding when to tackle some DIY repairs and when to leave it to the experts.

Software bugs

Software problems are the easiest to fix on a phone, though you shouldn’t automatically assume you can fix everything. Issues with one app in particular can often be sorted out by uninstalling and reinstalling the app, which should clear out any corrupted temporary data and reset everything back to normal.

If you’re noticing crashes and slowdowns more generally on your phone, we’ve written plenty of guides in the past on improving performance on Android and iOS—freeing up as much storage space as you possibly can is usually the way to go, as you can’t exactly upgrade the CPU and RAM. You should always install OS and app updates too, though these days it’s pretty hard to avoid doing that.

The most effective and comprehensive fix for software problems and slowdowns on your phone is always a hard factory reset, putting your phone back to the way it was when you first got it before all those nonsense apps and huge photo libraries took over. It’s not difficult to do, but you need to back up all your stuff first.

On stock Android devices, go to System then Reset in Settings (the version of Android you’re using may differ slightly); on iOS, you need to go to General and Reset inside Settings. After a few minutes, your phone will completely forget who you are, and you’ll have to start the setup process again.

Dropped phone

A dropped phone isn’t always cracked screens. Sometimes it causes smaller issues that can lead to frustrating hassles. It can mess with the contacts in the charging mechanism, so if your handset gives you the option to switch to wireless charging rather than a cable, see if that’s enough to bring your phone back to life.

A hard reset can sometimes bring a dropped phone back to life too, though the odds aren’t great. On an iPhone, you need to press and hold the Sleep/Wake button and the Volume Down button for at least ten seconds until you (hopefully) see the Apple logo; on Android, check the instructions from your manufacturer, but on the Pixel you just press and hold the power button for at least ten seconds.

Beyond those attempts there’s not a great deal you can fix it yourself unless you know your way around your phone as well as the folks at iFixit. It’s possible that some careful disassembling can fix whatever’s gone wrong ,but it’s something of a long shot.

Chances are that the drop has permanently damaged or dislodged something inside your phone, so a professional repair shop is really your best option—they’ll be able to take the phone apart for you, spot what’s gone wrong, and tell you whether the component can be fixed or replaced.

Smashed phone

A drop for your phone is usually associated with a screen smash. This could be anything from small and barely noticeable to large and stretching all across the display, and that’s also going to affect how you go about fixing it. If the damage is particularly bad then you’re going to need to replace the screen.

You can, if you want, tackle this yourself if you trust your hand-eye coordination and think you’ve got the skills for the job. iFixit has some excellent guides for Android and iOS so you can follow the instructions to get a new screen in place. Check the guide for your phone first and you’ll know how much effort is involved.

You’re going to need a screwdriver and a replacement screen, which shouldn’t be too difficult to source given the number of people prone to dropping their phones out of their pockets. You might want to compare the price of a new display against the price of getting everything fixed professionally to help decide what you want to do.

There’s no shame in admitting defeat and taking the phone in somewhere to be repaired by the experts. Apple will do it for you, as will some other manufacturers, and so will your local repair shop—these people do screen replacements all the time, so they’re likely to be much better and faster at it.

Dunked phone

Thankfully just about all modern-day handsets are now water resistant, though there are some outliers. If you’ve got a handset that’s not water resistant, and it’s taken a dunk, then you can try a few tricks to get it working yourself—it really depends on the extent of the damage and the make of phone.

Before you do anything else, turn the phone off, pop the SIM card out just in case, and wipe the handset down with a towel to see how much harm might have been done. Give it an hour or two to try out, and see if it comes back on. The key is to let the drying happen as naturally as possible, even if that requires a bit of extra patience. So don’t be afraid to wait 24 hours or longer before trying it out again.

If more drying is required, avoid using a hair dryer as the intensity of the heat can cause extra damage. According to the last local repair shop we visited in person, putting your phone in a bag of rice doesn’t make any difference to the moisture in the insides, but drying phones in a sealed container with silica gel is another common recommendation you might want to try.

Still the best bet is to just be patient and wait. If you turn the device on to soon it will get damaged. Once water damager has occurred there’s one solution left: Head to a professional phone repair service. The staff there won’t be able to work miracles, but they will be better able to safely disassemble and reassemble the phone components and allow them to try out components separately. If the phone still can’t be recovered, it’s time to think about an upgrade.

Dying Phone

In most cases water resistance in phones comes at the cost of a removable battery. That means when you’re battery starts to fail (usually about 3-4 years after purchase) it is time to either buy a new phone, or replace the battery in your current one. You’ll know it’s test when it doesn’t hold a charge for longer than a day, but you can double check by downloading a battery app like Battery Doctor (available for Android and iOS).

If you know your way around tiny tools and have steady hands than it’s not terribly difficult to replace the battery on a smartphone, it just takes a lot of patience and care. Batteries can usually be found for about $10-$15 online, and tutorials are available on Youtube or via iFixit.

If cracking your phone open and saving a few bucks doesn’t appeal than any repair shop can do replace it in about fifteen minutes. They charge anywhere from $50 to $100, so definitely shop around before walking into the closest repair shop.

If the shop doesn’t have the time (or the battery for your device) you’ll need to contact the manufacturer and hope it doesn’t charge too high a fee for a battery replacement. Apple, for example, charges a flat $80 for the repair. That’s a lot, but it is still less than the cost of a new phone.
