What is the phone most afraid of?

Do you know what the phone is most afraid of? The persecution of nature and your own negligence are the reasons for its shortened life! Here are five phones that are most afraid for your reference.

First fear: wet environmental damage:

Avoid using the phone in a humid environment (seaside/rain) to prevent large amounts of moisture from entering the board to form water spots, short circuits, or oxidation of the metal interface. Because if the charging hole is oxidized, there is a risk of burning when charging. The mobile phone should be used moderately to generate a certain temperature inside, and naturally evaporate the water vapor that is usually accumulated. If the mobile phone is not used for a long time, it needs to be specially protected from moisture. Soaking water: Obviously, what kind of things can still be alive after soaking in water? Sulfur: Avoid using mobile phones in places where sulfur is heavy, so as not to aggravate metal oxidation.


Second fear: damage caused by collision:

Basic common sense, mechanical collisions are easily damaged. Squeeze: The mobile phone is forced to oppress, although the damage is not as direct as the crash, but some screens have black spots, most of which are caused by the rupture and rupture of the liquid crystal. Because the pressure on the LCD screen can be quite limited, users should pay attention!

Third fear: damage to the temperature environment:

Mobile phones should be protected from heat exposure. In particular, the high temperature in the car in summer makes it easy for the board or battery to change due to high temperatures, and the screen is easily distorted due to material changes. Temperature difference: The temperature difference generated when the mobile phone enters and exits the air-conditioned room. The moisture generated by the cold air may corrode the circuit board, causing short circuit of the electronic components and affecting the life of the mobile phone!

The fourth fear: damage to the improper use of the battery:

If the original battery is not used, the contact between the phone and the battery is not as good as the original battery. Shake for a long time,
There may be loose joints and prone to momentary power outages.

Charging: Do not turn on the phone while charging, so as to avoid the high temperature of the phone charging the board. The car charger should be plugged in after the car is started, so as to avoid the instantaneous peak current flowing back to the mobile phone when the car is started, causing damage to internal parts. Friends who go abroad often have to bring some spare batteries. Otherwise, they must use the original charger to avoid the voltage difference and hurt the machine. Static electricity: The human body is charged with static electricity. If the disassembly and assembly of the mobile phone is not carried out on a platform that can discharge static electricity, it may cause the electrostatic entrainment to invade the fuselage and cause a short circuit.

Fifth fear: the harm of dust and grease:

The accumulation of dust can also interfere with current conduction between the board contacts. Grease: The long-term veneer of the mobile phone panel, the oil on the face may penetrate into the fuselage, pollute the internal lines, causing damage!

Out of battery,go charging?Oh no, your battery won’t accept!

A lithium battery, strictly speaking, is a lithium-metal or lithium alloy anode material, and a non-aqueous electrolyte solution is a disposable battery. The lithium battery we usually refer to is mainly a lithium-ion battery. It is a rechargeable battery that relies on lithium ions to move between the positive and negative electrodes to work. Lithium-ion batteries use an embedded lithium compound as an electrode material. At present, the main positive electrode materials for lithium ion batteries are: LiCoO2, LiMn2O4, LiNiO2 and LiFePO4.
Rechargeable lithium-ion batteries have a wide range of applications, and the batteries we use on various electronic devices are currently lithium-ion batteries. For example, mobile phones, tablets, laptops, and even electric cars.

The reason why it has such a wide range of applications is due to its superior nature. Taken together, it has high energy density, high average output voltage, low self-discharge, no memory effect, wide operating temperature range, excellent cycle performance, fast charge and discharge, high charging efficiency, large output power and long service life. There are quite a few advantages, such as no toxic or hazardous substances.
Lithium-ion polymer batteries are the most commonly used lithium-ion batteries and are very common on a variety of electronic devices. This lithium polymer is an improvement of ordinary lithium ion batteries. It replaces the liquid organic solvent in ordinary lithium ion batteries with colloidal or solid polymer. It has good safety, does not break out, and can shape various shapes. The battery. Therefore, such lithium polycarbon batteries are used in various handheld electronic devices and pure electric vehicles.

Compared with lithium-ion batteries on ordinary handheld electronic devices, lithium-ion batteries on modern pure electric vehicles have the following advantages:

1. The battery capacity is large. The battery capacity of modern pure electric vehicles is generally very large. For example, Tesla’s Model 3 series has the lowest battery capacity of 50 KWH, which is equivalent to 50 kWh. This large battery capacity is achieved by combining a series of lithium-ion batteries in series and in parallel.

2. The charging time is short. Today’s electric cars generally have a fast charge function. Generally, fast charging can be filled with 80% of electricity in half an hour, and the subsequent 20% takes a long time for security reasons. But this is already very convenient. For example, the domestic battery life of pure electric vehicles is generally around 200KM, 80% of the electricity has been able to drive around 160KM, which is enough for short-distance urban commuting.

3. Long battery life. The lithium polymer battery of a mobile phone or a notebook computer generally has a service life of less than 5 years, and the battery capacity will be seriously degraded after more than 5 years, which cannot meet the demand. However, the five years are short for electric vehicles and cannot meet the demand, because the average vehicle usage time will be more than 10 years. Therefore, the batteries of pure electric vehicles are generally improved lithium-ion batteries, and the service life is generally more than 10 years.

Of course, in addition to the above various advantages, lithium ion batteries also have some disadvantages, for example, intolerance to overdischarge. When overdischarged, excessively embedded lithium ions are fixed in the crystal lattice and cannot be released again, resulting in a shortened life, and deep discharge is more likely to damage the battery.

Therefore, using a low battery can damage the lithium ion battery. Therefore, whether it is a mobile phone, a laptop or an electric car, it should not be charged when the battery runs out. Generally speaking, if there are conditions, it should be charged when the battery has about 40%-50% of the battery. .

In addition, lithium-ion batteries are not tolerant of overcharging. When overcharging, the positive electrode of the battery will be deintercalated with too much lithium ions, and overcharging for a long time may cause the lattice to collapse, thereby irreversibly reducing the capacity of the lithium ion battery.

In short, the emergence of lithium-ion battery technology has accelerated the popularity of electronic devices, such as mobile phones and notebook computers. In addition, the commercialization of pure electric vehicles is also inseparable from the development of lithium-ion battery technology. Lithium-ion batteries with large capacity and fast charge and discharge will definitely drive the development of the pure electric vehicle market.

Should I charge to 100%?

Experts recommend that you do a full zero to 100 percent battery recharge (a “charge cycle”) maybe once a month only. This recalibrates the battery – a bit like restarting your computer, or, for humans, going on holiday! The same goes for laptops, by the way.

When should I charge my phone?

The rule with Li-ion batteries is to keep them 50 percent or more most of the time. When it drops below 50 percent top it up a little if you can. A little a few times a day seems to be the optimum to aim for.

But don’t charge it all the way to 100 percent . It won’t be fatal to your battery if you do a full recharge – most of us are forced to do this every now and again in emergencies. But constantly doing a full recharge will shorten the battery’s lifespan.

So a good range to aim for when charging a Li-ion battery is from about 40- to 80 percent in one go. Try not to let the battery drop below 20 percent.

What is battery memory effect?

Battery memory effect is about batteries remembering remaining charge if you don’t let them go all the way to zero too often. So a battery frequently charged from 20- to 80

Sounds crazy but that’s sort of true – but only for older nickel-based (NiMH and NiCd) batteries, not the lithium-ion batteries in your modern phone.

Lithium-ion (Li-ion) batteries don’t suffer the memory effect so you almost need to do the opposite: charge them often but not all the way throughout the day, and don’t let them drop to zero.

Should I use fast charging?

​Many Android phones have a feature that allows for fast charging, often referred to as Qualcomm Quick Charge or, in Samsung’s case, Adaptive Fast Charging – there are others.

These phones have special code usually located in a chip known as the Power Management IC (PMIC) that communicates with the charger you are using and requests that it send power at a higher voltage.

The iPhone 6 doesn’t feature fast charging, but its Qualcomm PMIC is smart enough to recognise when you use a higher-amp charger (like the one you get with the iPad), and that’s a good thing because fast charging will heat up that Li-ion battery and cause it increased wear and tear.

For the same reason, you should never leave your phone in a hot car, on the beach or next to the oven. A hot battery will suffer long-term effects on its lifespan. And so will a super-cold one, so don’t leave your device in the freezer or out in the snow.

How to Extend Phone Battery Life

1. Dim the screen brightness or use auto brightness

You love your smartphone’s large, colourful display, but it’s the battery’s mortal enemy. More than any other component of your phone, the display consumes battery life at a devastating pace. Most phones include an auto-brightness feature that automatically adjusts the screen’s brightness to suit ambient lighting levels.

This mode uses less power than constantly running your screen at full brightness would, of course, but you’ll get even better results by turning your screen’s brightness down to the lowest setting that you can tolerate and leaving it there. Even if you do nothing else we suggest, following this one tip will extend the life of your battery dramatically.

2. Keep the screen timeout short

Under your phone‘s display settings menu, you should find an option labeled ‘Screen Timeout’, ‘Sleep’ or something similar. (On an iPhone, look for Auto-Lock in the General settings menu.) This setting controls how long your phone’s screen stays lit after receiving input, such as a tap.

Every second counts here, so set your timeout to the shortest available time. On most Android phones, the minimum is 15 seconds. If your screen timeout is currently set to 2 minutes, consider reducing that figure to 30 seconds or less.

3. Turn off Bluetooth

No matter now much you love using Bluetooth with your hands-free headset, your wireless speaker or activity tracker, the extra radio is constantly listening for signals from the outside world. When you aren’t in your car, or when you aren’t playing music wirelessly, turn off the Bluetooth radio. This way, you can add an hour or more to your phone’s battery life.

4. Turn off Wi-Fi

As with Bluetooth, your phone’s Wi-Fi radio is a serious battery drainer. While you will at times need to use your home or office Wi-Fi connection rather than 3G or 4G for internet access and other data services, there’s little point in leaving the Wi-Fi radio on when you’re out and about. Toggle it off when you go out the door, and turn it back on only when you plan to use data services within range of your Wi-Fi network.

In iOS it’s easier than ever to toggle Bluetooth and Wi-Fi on and off. Simply swipe up from the bottom of the screen to display the Control Centre.

The exception to this rule is for location services, since Wi-Fi can help your phone to obtain a GPS fix using less power (see myths section below).

5. Go easy on the location services and GPS

Another big battery sucker is apps using GPS, Wi-Fi and mobile data for monitoring your location. As a user, you can revoke apps’ access to location services, or set levels (in Android) to determine how much power they use. In Settings > Location, you can choose High accuracy when you need it, or Battery saving when you don’t.

Both iOS and Android have battery monitors, so you can check exactly how much each app is using and easily spot those which are using too much power. Then you can either uninstall them or simply make sure you quit them when you’re not actually using them.

6. Don’t leave apps running in the background

Multitasking – the ability to run more than one app at a time – is a powerful smartphonefeature. It can also burn a lot of energy, because every app you run uses a share of your phone’s processor cycles (but this isn’t true of all apps – see the myths section below).

By killing apps that you aren’t actually using, you can drastically reduce your CPU‘s workload and cut down on its power consumption.

In Android, tap the multi-tasking button – usually the right-most of the three icons at the bottom of the screen – and you can swipe away apps to close them.

In iOS, double-tap the Home button so the multitasking screen appears, then swipe upwards to close the app.

Both iOS and Android have battery monitors, so you can check exactly how much each app is using and easily spot those which are using too much power. Then you can either uninstall them or simply make sure you quit them when you’re not actually using them.

7. Don’t use vibrate

Prefer to have your phone alert you to incoming calls by vibrating rather than playing a ringtone? We understand the inclination; unfortunately, vibrating uses much more power than playing a ringtone does. After all, a ringtone only has to make a tiny membrane in your phone’s speaker vibrate enough to produce sound.

In contrast, the vibration motor rotates a small weight to make your whole phone shake. That process takes a lot more power. If you don’t want to be disturbed audibly, consider turning off all notifications and leave the phone in view so you can see when a new call is coming in. This approach is as courteous to your battery as it is to your friends and colleagues.
