6 ways to improve your laptop’s battery life on Windows 10

Don’t let your portable PC run out of power. Follow these tips and you’ll get a lot more battery life out of your Windows 10 machine.

Battery life is always a crucial part of any PC, whether it’s old or brand new.

We’ve already explained some techniques to preserve power on Windows 7 but what about Microsoft’s latest addition Windows 10? Thankfully if you’re using the new operating system, there are a number of simple tips that will help you save on power so you can continue using your PC that little bit longer. Watch the video below to see some of the tips in action and follow our guide for more details.

Tip 1: Turn off wi-fi and Bluetooth

Windows 10’s new Action Center makes it easier to switch off connectivity options such as wi-fi and Bluetooth which can drain battery life.

If you don’t need or Bluetooth on all the time, go to the Action Center by clicking the small square icon near the time in the bottom right, and click on Bluetooth to deactivate them so that they’re no longer lit. Older machines may not have Bluetooth, in which case you won’t see that option.

Wi-fi is usually used a lot of the time, but if you don’t need to be online for a while (perhaps if you’re writing a letter using a word processor) you can always click the Wi-fi icon to turn it off, which will save some battery as well.

Alternatively, if you want to switch all connectivity options off for a certain period of time, click Airplane mode and it’ll cut off all connections for you. When you want them back, simply click Airplane mode again.

Tip 2: Turn on Battery Saver

For laptops that aren’t plugged in to a power source, Windows 10’s new Battery Saver is a great way to preserve some of your machine’s juice.

Battery Saver does what its name suggests by reducing screen brightness, stopping push notifications and preventing apps from running in in the background.

Battery Saver is automatically set to kick in whenever your battery falls below 20%, but you can switch it on at any time (if mains power is not connected) from the Action Center.

You can also set Battery Saver to start automatically a bit earlier or later too, by going into the settings menu. Simply search for ‘Battery’ in Cortana and select Change battery saver settings at the bottom.

From here you can adjust the point at which Battery Saver will kick in by moving the scrolling bar.

Tip 3: Turn the sound down

Your PC’s speakers use up a decent amount of power, so turning them down even a little bit could help save some of your battery’s life.

Headphones also use less battery than speakers, so if you can opt for a pair instead, all the better.

Tip 4: Turn screen brightness down

The brightness of your screen is another big battery sucker. You can turn it down a notch or two by searching for ‘Brightness’ in Cortana and clicking on Display settings.

Under ‘Adjust brightness level’, move the scrolling bar down – but make sure it’s still bright enough to use.

Tip 5: Adjust power and sleep settings

Leaving your PC idle is a waste of battery, so make sure you’ve got the best screen and sleep options set-up.

Search ‘Power’ in Cortana and select Power & sleep settings.

Here, you can adjust how long your PC should wait before the screen dims or goes into sleep mode. Select a suitable time that you’re comfortable with from each drop down box.

Tip 6: Unplug any peripherals you’re not using

Got a USB stick plugged in all day but not using it? Remove it! Even if you’re not actively using it yourself, your PC will still be powering it.

How to Use iPhone Low Power Mode for Longer Battery Life

Squeezing the longest use out of your iPhone battery is crucial. There are dozens of tips and tricks to help you, but if your battery is very low right now or you won’t be able to charge for a while, here’s one simple tip to conserve battery life: turn on Low Power Mode.

Low Power Mode is a feature of iOS 9 and up that disables some features of the iPhone in order to make your battery last longer.

How Much Extra Time Does Low Power Mode Get You?

The amount of extra battery life Low Power Mode delivers is dependent on how you use your iPhone, so there’s no single prediction.

According to Apple, though, the average person can expect to up to get an extra 3 hours of battery life.

How to Turn On iPhone Low Power Mode

Sound like something you want to try? To turn Low Power Mode on:

  1. Tap the Settings app to open it.
  2. Tap Battery.
  3. Move the Low Power Mode slider to On/green.

To turn it off, just repeat these steps and move the slider of Off/white.

This isn’t the only way to enable Low Power Mode, though. The iPhone gives you other options:

  • Siri—Just tell Siri “turn on Low Power Mode” (or a variation of that phrase) and she’ll take care of it for you.
  • Pop-up Window—When your iPhone’s battery life drops to 20%, and then again at 10%, the iOS displays a pop-up warning. In that warning is a button that can turn on Low Power Mode. Tap it to start saving battery.
  • Control Center—In iOS 11 and up, you can add Low Power Mode to Control Center. Check out the section at the end of the article for more on this.

What Does Low Power Mode Turn Off?

Making your battery last longer sounds great, but you have to understand the trade-offs to know when it’s the right choice. When Low Power Mode is enabled, here’s how the iPhone changes:

  • Processing power is reduced—The speed of the iPhone’s processor influences how much battery it uses. Low Power Mode reduces the performance of the processor and the graphics chip to conserve battery. This means your phone will be a little slower and might not perform as well in games and other graphics-intensive tasks.
  • Background App Refresh is disabled—Your iPhone learns how you use apps and automatically updates them around the times you use them to ensure that the latest data is always waiting for you. It’s a cool feature, but it also requires battery life. Low Power Mode temporarily suspends this feature.
  • Email fetch is turned off—The iPhone can be set to periodically grab new email from your accounts. Low Power Mode turns this feature off and forces you to manually check for new messages (open Mail and swipe down from the top on any inbox to refresh).
  • Automatic downloads are disabled—You can set your iPhone to automatically download app updates or purchases made on other devices. This keeps your content in sync, but it also requires power. Low Power Mode prevents automatic downloads while it’s on.
  • Visual effects and animations are suspended—The iOS is packed full of all sorts of cool visual effects and animations. They make using the iPhone more fun, but they also use battery. By turning them off, Low Power Mode saves power.
  • Screen brightness is turned down—The brighter your phone’s screen, the more battery you use. Low Power Mode reduces your screen brightness to save energy.

Can You Use Low Power Mode All the Time?

Given that Low Power Mode can give your iPhone up to 3 hours of extra battery life, and the features it turns off aren’t completely essential to using the phone, you may wonder if it makes sense to use all the time.

Writer Matt Birchler tested that scenario and found that Low Power Mode can reduce battery use by 33%-47% in some cases. That’s a huge savings.

So, if you don’t use the features listed above very much, or are willing to give them up for more juice in your battery, you could use Low Power Mode all the time.

When Low Power Mode Is Automatically Disabled

Even if you’ve turned on Low Power Mode, it’s automatically turned off when the charge in your battery exceeds 80%.

Adding a Low Power Mode Shortcut to iOS 11 Control Center

In iOS 11 and up, you can customize the options that are available in Control Center.

One of the changes you can make is to add Low Power Mode. If you do this, turning the mode on is as simple as opening Control Center and tapping a button. Here’s how to do that:

  1. Tap Settings.
  2. Tap Control Center.
  3. Tap Customize Controls.
  4. Tap the green + icon next to Low Power Mode. It will move into the Include group at the top.
  5. Open Control Center and the battery icon at the bottom of the screen toggles Low Power Mode on and off.

Maintain Lithium Battery

Lithium batteries are presently the most commonly used energy storage devices on mobile phones, laptops, digital cameras and other electric devices. Learning how to maintain lithium batteries can not only prolong battery lifetime but also protect your device from potential damage.

Here attached the steps for your reference.

1.Use appropriate chargers. Many people take great care with their electronic gadgets, but often neglect the consequences of bad chargers on their lithium ion batteries. When choosing a charger, the original charger is the best choice. If that’s unavailable, a high quality charger that has an overcharge protection function, or a brand name charger will do. A low quality battery charger can lead to shorter run times, premature battery failure, or even fire or explosion.

2.Avoid frequently over charging. Over charging with a low quality charger may let the battery’s interior rise to a high temperature, which is bad for the lithium ion battery and charger. Thus, simply fully charging is good enough – overcharging will make your lithium battery into a little bomb if overcharge protection function is missing.

3.Avoid touching metal contacts. All batteries’ contacts need to be kept clean for best performance. When carrying batteries around, do not let the contacts touch metal objects such as keys; this could cause a short circuit, damaging the battery or potentially resulting in a fire or an explosion.

4.Avoid using often in high or low temperature environments. Lithium ion batteries have optimal working and storage temperatures. If they’re continually used in extreme temperature environments, this will negatively affect battery use time and useful cycles.

5.Avoid long periods without using or recharging. If batteries will be left unused for 3 months or more, partially recharge them, then store the device to prevent battery damage. You may need to take the device out of storage and charge again after a few months.

6.Avoid using lithium ion batteries which are hot after being fully charged. Temperatures can be very high when batteries are freshly recharged. If you use them immediately, the electronic gadget’s internal temperature will rise, which may negatively affect the device’s electronic components.

How to Extend Your Laptop’s Battery Life

Still remember the last time the last drop of power of the original battery? You hate the battery for it almost ruined your most important presentation to your clients. But by following certain  practices, you will change your affections towards your moving energy friend. Here’s how.

The fewer you drain it, the longer the battery last

Usually, laptop batteries are able to handle around 500 full charge cycles, which means, each charge cycle decreases a battery’s capacity from its design specifications.

Your laptops like “new mode”

You can start saving your battery by changing the power settings corner of your laptop.

It would be better, If your laptops offer the function of “eco mode” which may adjusts the way power automatically to conserve battery energy. And, shifting to the Hibernation mode once you leave for a moment is really a good habit for laptop battery life.

Less running app, more energy

To save even more power, take a tour of your apps and quit any that are running in the background and slowly eating into your battery life. No matter your computers are in Windows or macOS , you can what apps are using the most power by resetting the energy section. Both Microsoft and Apple offer you the instruction in video.

Besides, you can also reduce the amount of power by shutting off Wi-Fi or Bluetooth when you’re absent, turning off optional features such as keyboard backlighting.

Half charging for laying up

Though battery life is longer than before, it does not mean that the energy will be always waiting for you for a long time ignorance. So if you have the plan to store your laptop for an time without using it, then charging it to 50 percent before putting it away will be better.

How to Know When It’s Time to Replace Your Laptop’s Battery

No matter how well you treat your laptop’s battery, it will eventually die. If you’re lucky, it will be time to replace your laptop by the time its battery dies. If you’re not, you’ll need to replace the battery.

Battery death can seem sudden, but it doesn’t have to. Windows will warn you when your battery reaches extremely low capacity levels, but you can also keep your own tabs on its capacity.

Windows Will Warn You

Windows doesn’t normally keep you up-to-date with your battery’s capacity level. As you use it and it weakens, you’ll just notice that your laptop doesn’t seem to last as long on battery.

Eventually, when your battery reaches a low enough capacity level, Windows will warn you. You’ll see a red X appear on the standard battery icon in your system tray and, when you click it, Windows will inform you that you should “consider replacing your battery.” Windows also says that your computer might shut down suddenly because there’s a problem with your battery — in other words, your battery can’t hold enough of a charge to power your laptop for long when it’s not connected to an outlet.

Note that this warning was added in Windows 7, so you won’t see it if you’re using Windows Vista or XP.

How to Check Your Laptop’s Battery Capacity

If you’re curious just how far your laptop’s battery capacity has declined, you can use a third-party tool to view it. NirSoft’s free BatteryInfoView does this well, displaying the battery’s approximate wear level, the capacity it was designed to have, and the capacity it currently has.

Calibrating Your Battery

The information above may not be completely accurate if your battery requires calibration. For example, we had a battery that reported it was almost dead. Windows warned us that it was time to replace the battery and the battery appeared to be at 27.7% wear level according to its reported capacity.

After we calibrated the battery, Windows stopped warning us and the battery’s reported capacity went back up to 70.8%. The battery didn’t actually gain any additional charge, but the calibration helped the battery’s sensor actually detect how much capacity was in the battery. If Windows says it’s time to replace your battery, be sure to calibrate it first before checking its actual wear level. If you don’t, you may replace a battery that’s still in good enough shape. That would just be a waste of money.

Why Your Laptop’s Battery Capacity Declines

Laptop batteries decline due to a number of factors. Heat, usage, age — all of these things are bad for batteries. Batteries will slowly die no matter what — even if you put your battery in a closet and never touched it, it would slowly lose capacity due to age. However, if you never use your battery — say you use your laptop at your desk most of the time and it gets rather hot, which is bad for the battery — removing the battery can certainly help prolong its life.

Replacing Your Battery

If your laptop has a user-serviceable battery — that is, one you can remove on your own — you can replace your battery fairly easily. If your laptop doesn’t have a user-serviceable battery, you’ll need to contact the laptop’s manufacturer so they can crack your laptop open and change its battery for you.

Assuming you have a user-serviceable battery, you can order a replacement battery for your laptop model online. Don’t just head to eBay and buy the cheapest third-party batteries available — buy official batteries from a reputable company. Aftermarket batteries are often built on the cheap, with cut corners and insufficient testing. They can be dangerous — a cheap, counterfeit, and improperly designed battery could literally go up in flames.

Make Your Battery Last Longer

Mobile phones come with lithium batteries which require some maintenance as long as they are used. Once you know how, you can optimize your phone’s battery life fairly easily.

1.Turn the phone off. Only do this if it’s going to be for several hours; turning a phone on/off actually uses a massive amount of power itself. This will probably be the most effective and simple way of conserving your battery’s power. Why? This will help conserve energy and also charge your phone. If you don’t plan on answering the phone while you’re sleeping or after business hours, just turn it off.

2.Stop searching for a signal. When you are in an area with poor or no signal, your phone will constantly look for a better connection, and will use up all your power doing so. This is easily understood if you have ever forgotten to turn off your phone on a flight. The best way to ensure longer battery life is to make sure you have a great signal where you use your phone. If you don’t have a perfect signal, get a cell phone repeater which will amplify the signal to provide near perfect reception anywhere or simply turn on flight mode.

3.Do not follow the method of full charge and full discharge. Avoid letting your cell phone’s battery run all the way down. Lithium-based batteries are designed to be charged early and often, and letting them get too low can damage the battery. With lithium-based batteries, doing shallow discharges and frequent charging prolongs battery life.

  1. Switch the vibrate function off on your phone. Use just the ring tone. The vibrate function uses additional battery power. Keep the ring tone volume as low as possible.

5.Turn off your phone’s back light. The back light is what makes the phone easier to read in bright light or outside. However, the light also uses battery power. If you can get by without it, your battery will last longer. If you have to use the back light, many phones will let you set the amount of time to leave the back light on. Shorten that amount of time. Usually, one or two seconds will be sufficient. Some phones have an ambient light sensor, which can turn off the back light in bright conditions and enable it in darker ones.

6.Avoid using unnecessary features. If you know it will be a while before your phone’s next charge, don’t use the camera or connect to the Internet. Flash photography can drain your battery especially quickly.

7.Keep calls short. This is obvious, but how many times have you heard someone on their mobile phone say, “I think my battery’s dying,” and then continue their conversation for several minutes? Sometimes, the dying battery is just an excuse to get off the phone, but if you really need to conserve the battery, limit your talk time.

8.Turn off Bluetooth. It will drain your battery very quickly. Only turn Bluetooth on when needed.

9.Same goes for WIFI, GPS, and infrared capabilities, if your phone has these features built in. Keep them off except when you need them.

How Do You Know When It’s Time to Replace Your Battery?

Batteries don’t last forever. As you charge and discharge your battery, it degrades and over time, you get less battery life from a full charge. Eventually, the battery—or the device—needs to be replaced.

Battery Capacity Decreases Over Time

A battery doesn’t just go from good one day to bad the next. Instead, batteries slowly degrade over time. This capacity decrease is a gradual process—happening over many charge cycles—and you won’t necessarily notice until you realize you used to get a few more hours of battery power from a charge.

You can help prolong your battery’s life and keep its capacity up by properly caring for your battery. But you can’t avoid battery degradation forever. If you replace devices often—say a new phone every couple of years—you may never notice. Or, you may notice but the problem won’t get bad enough to do anything about before it’s time to replace your device again. But for devices like laptops, which you’re likely to keep for longer, you may have to replace your battery at some point.

Some devices will even warn you when it’s getting time to replace your battery. For other devices, you can often find third-party apps that let you check up on your battery’s health.

How to View a Device’s Battery Health

Unfortunately, many devices don’t display battery health warnings ahead of time. You’ll either notice a problem yourself or the battery will simply fail. Even devices that do include some kind of warning often don’t give you much advance notice. It pays to check up on battery health yourself once in a while.

Here’s how to find battery health information on some common operating systems and devices:

  • Ÿ Windows Laptops: We recommend NirSoft’s BatteryInfoView to find a Windows laptop’s battery health, but there are other utilities you can use instead.
  • Ÿ MacBooks: Hold down the Option key and click the battery icon on the menu bar. You’ll see a “Condition:” line displayed here.
  • Ÿ iPhones and iPads: You can actually ask Apple support to tell you your iPhone or iPad’s battery health
  • Ÿ Android Phones: Unfortunately, most Android users are out of luck. Some older phones would show battery health information if you opened the dialer and typed *#*#4636#*#*, but this doesn’t seem to work on modern phones.

For other devices, search for the type of device and “battery health” to get instructions.

When It’s Time to Replace a Battery

Whatever your device says about the health of its battery, the rest is up to you. If your battery reports it’s at 40 percent of its original capacity, but you’re still happy with how much battery life you get, there’s not much need to pay for a replacement until it declines to a point where it becomes bothersome.

How to Replace a Battery

If you have a smartphone, tablet, laptop, or another device with a removable battery, replacement is easy. You just need to purchase a replacement battery designed specifically for your device, power down your device, and then replace the current battery with the new one. This gives your device a fresh battery with maximum capacity.

However, devices these days are often made so that you can’t access the battery yourself—at least not easily or without voiding your warranty. Instead, you’ll need to have the manufacturer replace the battery for you. For example, you can take an old iPhone, iPad, or MacBook to an Apple Store and pay a fee to have Apple employees open your device and replace the battery for you. Check if your manufacturer offers this service.

Of course, even on devices without an easily accessible battery, if you’re so inclined and don’t mind the associated risks, you always have the option of doing it yourself. You could  open up your device, get a replacement battery, and try to seal it back up again. We don’t necessarily recommend this, though. Too many modern devices have batteries and other components that are glued together and not designed to be opened.

The battery health status your device reports can help you decide whether it’s time to replace your battery, but the decision is ultimately up to you. If your battery feels okay to you, then you don’t need to do a thing right now. Better to put that money toward a future device replacement. If the battery is no longer performing adequately and you’re not interested in replacing your device, then it’s time for a replacement.

How to Increase Your Windows Laptop’s Battery Life

We often fixate on smartphone battery life, but most laptops still don’t have all-day battery life. Rather than tethering your laptop to an outlet, here are some ways to squeeze more life from your laptop’s battery.

None of these tricks will turn a laptop without much stamina into an all-day workhorse, but they’ll help you go without an outlet for a while longer. Pay particular attention to your laptop’s display—that’s a big battery sucker.

Use Windows 10’s Battery Saver Mode

If you want to extend your battery life without thinking too much about it, enable Windows 10’s Battery Saver mode. Windows automatically enables this feature when you’re down to 20% battery by default, but you can manually enable it whenever you like. So, if you know you’ll be away from an outlet for a while, you might enable it at the start of a long day.

Battery saver performs a few tweaks automatically, like limiting background activity and lowering screen brightness to achieve longer battery life.

To enable Battery Saver mode, click the battery icon in your notification area and drag the Power mode slider to the “Best battery life” point on the left.

Reduce Your Display’s Brightness

The biggest battery drain on any modern portable electronic device—whether it’s a laptop, smartphone, or tablet—is the display. Reducing your screen’s brightness is a simple way to squeeze significantly more time from your laptop’s battery.

On a typical laptop, you’ll just need to press the brightness buttons on your laptop keyboard (on some laptops, you may need to hold the Function (Fn) key while pressing the brightness buttons). The lower the brightness level, the longer you can use your laptop on battery power.

On Windows 10, you can also open the Action Center by clicking the notification icon on your taskbar and click the brightness icon to adjust brightness (click “Expand” if you can’t see it). You can also head to Settings > System > Display and adjust the slider here

Check Which Applications Are Using the Most Battery on Windows 10

Windows 10 allows you to see which applications are draining your battery the most. It does this by tracking CPU usage over time, then listing which programs are using the most power. This feature isn’t available in Windows 7.

To access this list, head to Settings > System > Battery > Battery Usage By App. This screen will show you which applications are using the most battery. This doesn’t necessarily mean the application is bad—the applications you use the most will probably have used the most battery power, of course. But you may want to consider switching to more power-friendly applications if something is unusually heavy, or close background applications that seem to use a lot of power even when you’re not actively using them.

Turn Off Your Screen and Go to Sleep Sooner

Since the display uses so much power, it’s important not to have it on longer than necessary. You can configure your laptop to automatically go to sleep sooner when you’re not actively using it—or at least turn off its display to save power.

This won’t help your battery life if you’re actively using the laptop the whole time, or always put it to sleep immediately when you’re done, but it can ensure your laptop doesn’t waste power by running for too long when you step away.

Disable Bluetooth and Other Hardware Devices

Hardware devices you don’t use can also waste battery power for no good reason. For example, if you never use any Bluetooth accessories with your laptop, you can turn off the Bluetooth hardware radio to eke out some more battery life. (f you do use Bluetooth accessories regularly, toggling Bluetooth on and off may not be worth the trouble, as the Bluetooth hardware in modern laptops is more power efficient than it once was.)

Tweak Your Power Plan

On Windows 7, you can save energy by selecting the “Power saver” Power Plan from Control Panel > Hardware and Sound > Power Options. This isn’t necessary on Windows 10, as you can just use Battery saver mode instead.

You can change a variety of settings from the Power Options window that appears, including configuring your laptop to power off its hard drive more quickly and telling your computer to slow down the processor rather than turning on the fan if it becomes hot. Both of these behaviors will save power. The default settings should be fairly optimal if you select Power saver mode, but you can make the settings even more aggressive in some areas, if you like.

Run the Windows Power Troubleshooter

Windows 7, 8, and 10 include a power troubleshooting tool that will scan your system for common battery drains and automatically fix them. For example, this tool will automatically decrease the time before the display dims if it’s too long, or disable the unnecessary screensaver feature if it’s enabled.

Lighten Your Software Load

To save power, make your computer do less in general. For example:

  • Don’t use a screensaver. They’re unnecessary on modern displays and will drain your battery to do nothing useful when your display could be off and saving power.
  • Run fewer programs in the background. Examine your system tray for programs you don’t need and uninstall them or disable them and prevent them from automatically starting with your computer.
  • Reduce CPU usage. If you use heavy programs that have your CPU doing a lot of work all of the time, your CPU will use more power and your battery will drain faster. Running fewer programs in the background can help with this, as can selecting lightweight programs that are easy on system resources.
  • Avoid maxing out your RAM. If your computer fills its RAM and needs more memory, it will move data to the page file on its hard drive or SSD, and this can drain battery power. This shouldn’t be as much of a problem on modern computers with a decent amount of RAM. If your laptop’s RAM is full, try to make more RAM available—close programs running in the background or even upgrade your laptop’s RAM.

The less your computer has to do, the more power it can save. You can find more information about CPU and RAM usage in your Task Manager.

Take Care of Your Laptop Battery

All batteries lose capacity over time, so your laptop’s battery life will decline no matter what you do. But there are ways to keep your battery as healthy as possible.

For example, don’t always run your laptop down to 0% battery—try to charge it before that. Over the long run, keeping your laptop battery cool will also prevent unnecessary wear and tear caused by heat. Heat is a battery’s biggest enemy.

7 tips to extend your tablet’s battery life

Whether you’ve got a Tesco Hudl or a Nexus 7, a few simple tweaks can help you eke more life out of your Android tablet’s battery.

Step 1: Check what’s sapping your tablet’s power

Android provides a quick and easy way to see what’s draining most of your tablet’s power. Go to Settings > Battery. This will show you a bar graph of the different hardware, apps and processes that are putting the most drain on your battery.

The greatest drain is almost always the screen, as powering the backlight for your tablet’s large display uses a lot of energy.

Step 2: Turn the screen brightness level down

Adjusting the brightness level of your tablet’s screen can save a lot of battery power. To do this, open Settings > Display > Brightness. A pop-up window will display a slider which you can use to change the brightness level. If the slider isn’t visible untick the box marked Automatic Brightness. Reduce the brightness to a level that’s less intense but still comfortable for you to read text on your screen without straining your eyes.

Step 3: Reduce the screen time out

Reducing the amount of time your screen stays lit after you’ve stopped interacting with your tablet is another good way of slowing battery drain. Return to the Settings > Display menu and select Sleep. Reducing this setting tells your tablet to turn off the screen after a set period of inactivity. The shorter the time you select, the less power your display will use. Try changing it to a setting of two minutes.

Step 4: Turn off unwanted connections

Wireless network technologies such as wi-fi and Bluetooth also consume quite a bit of power, so if you’re not using them it’s best to turn them off. This is especially true of Bluetooth, which many people never use on their tablet yet still leave turned on.

Go to Settings and select Bluetooth under the Wireless & Networks heading. Flick the switch to Off to disable Bluetooth.

If you’re using your tablet on a long bus or train journey – or anywhere there’s no wi-fi reception, you should also turn off wi-fi to save power. Open Settings and switch the wi-fi toggle switch to Off.

Step 5: Avoid using live wallpapers and widgets

Android’s Live Wallpapers and Widgets require processing and graphics power to run so put extra drain on your battery. It’s a relatively minor amount, but if you do want to absolutely maximise your tablet’s battery life you may want to get rid of them.

Delete widgets from your homescreen by tapping and holding on them before swiping them up to the Remove icon. To change your wallpaper, tap and hold on an empty part of your homescreen and choose Wallpaper from the pop-up menu.

Step 6: Fully discharge the battery

The lithium ion batteries used in almost all Android tablets don’t suffer the over-charging problems of older Ni-Cad batteries, so they don’t always need to be run down completely to stay at their best. However, to keep the battery’s power meter correctly calibrated it’s still a good idea to let your tablet run out of battery power after every 30 or so charges.

Step 7: Turn off Auto-sync

There are various apps and services on your tablet that automatically sync data with online servers, for storing contact information, providing Facebook alerts and sending email to your tablet. These syncing processes can drain power, especially if they’re pulling in a lot of information.

You can see which accounts are set up to auto-sync by opening Settings and choosing Accounts and Sync. If there are any you don’t want or need to sync in the background just tap on their name and untick the Sync option.

Gain Better Digital Camera Battery Life

If you’ve noticed your digital camera’s battery power not lasting quite as long as it used to, that’s not a surprise. Rechargeable batteries tend to lose their ability to hold a full charge as they age and are re-used. Losing digital camera battery power is a frustrating problem to have, especially if your “battery empty” light flashes just as you prepare to take that once-in-a-lifetime photo. These tips and tricks should help you gain a little extra digital camera battery life …

even from an older camera battery.

Viewfinders save battery power

If your camera has an optical viewfinder (the small window at the back of the camera that you can use to frame images), you can turn off the LCD screen and only use the viewfinder. The LCD screen has large power demands.

Limit using the flash

Try to avoid using the flash, if at all possible. Continued use of the flash also drains the battery quickly. Obviously, there are some situations where a flash is required to create the photo, but, if you can shoot the picture with the flash turned off, do it to save some battery power.

Limit using Playback mode

Do not spend a lot of time reviewing your photos. The longer you have the LCD screen on — while you aren’t actually shooting photos — the faster your battery will drain in comparison to the number of photos you can shoot per charge. Spend more time reviewing your photos later when you return home and you have a fresh battery.

Activate power saving features

Use your camera’s power saving feature. Yes, I agree that this feature can be extremely annoying at times, as the camera goes into “sleep” mode when you haven’t used it for a set period of time. However, it does work to conserve battery power. To achieve the most battery power savings, set the “sleep” mode to kick in as quickly as possible.

With some cameras, this can be after as little as 15 or 30 seconds of inactivity.

Reduce screen brightness

Turn down the LCD’s brightness level, if your camera allows this. A brighter LCD drains the battery faster. A dimmer LCD is more difficult to see, especially in bright sunlight, but it will help extend your battery life.

Don’t expect to match the manufacturer’s battery life claims

Don’t believe the claims of the manufacturer about how much life your batteries should have. When testing the battery life of their cameras, most manufacturers will conduct their measurements in perfect conditions, something you likely cannot recreate in real-world photography. If you’re able to achieve at least 75% of the battery life that the manufacturer claims, that’s a good starting point.

Newer batteries work better

To obtain the longest life from your batteries, don’t fall for the myth that says you should fully drain the battery before recharging it. In reality, a battery has “X” number of hours of use in it. If you’re using some of those hours to simply drain the battery, it won’t last as long over its lifetime. Just use the battery normally, and charge it when the battery needs a charge or when you’re done shooting.

A partial charge isn’t going to significantly affect the life of the modern battery. That may have been the case with rechargeable batteries from several years ago, but it’s not true with newer batteries.

Don’t turn the camera on and off repeatedly

Each time you restart most cameras, the introductory screen will appear for several seconds. Although this doesn’t seem like much time, if you turn the camera on and off 10 times, you’ll probably lose at least a minute of battery power, which may be the difference between snapping that last great photo and seeing the “battery empty” message. Use the “sleep” mode instead, which I discussed earlier.

Consider replacing older batteries

Finally, because all rechargeable batteries tend to hold less power as they age, you may simply want to purchase a second battery and have it charged and available. If you find yourself constantly altering your photography habits to try to conserve power with an older battery, you’re better off buying a second battery as a backup or an “insurance policy.”
