It's kind of cold to call the mobile phone freeze-shut down. The cold current has swept across China. In most areas, there is a temperature drop of about 10 ℃, and even the mobile phone can't hold up. Many netizens reported that the mobile phone has been frozen and turned off. After going out, the mobile phone clearly shows 40% 50% of the remaining power, and then suddenly turns off automatically! As a result, once the charger is plugged in, the charging starts automatically, indicating that there is still 40% 50% power left! Will the phone really freeze shut down?
1、 Performance of mobile phone freeze shutdown:
1. Mobile phone charging is slow and power consumption is fast;
2. Automatic shutdown, crash and failure to start without reason;
3. Screen touch failure or even drift;
4. Unable to connect to the network.

2、 Why does the mobile phone lose power in winter?
At present, mobile phones use lithium-ion batteries. The capacity of ordinary lithium batteries will be reduced by 20% at zero degrees Celsius. When it reaches minus 10 degrees Celsius, the capacity may be only about half.
3、 What if the mobile phone is turned off
1. Forced restart
In theory, forced restart cannot be started when the temperature remains unchanged, but in practice, it is possible to start, which has a lot to do with character. At the same time, it is better to force restart with some interval, and the probability of restart will be greater. But even if you restart it, it will shut down quickly because the temperature is too low.
2. Find a place to warm up
If the mobile phone suddenly turns off, the most reliable thing at this time is to find a room to warm up quickly and put the mobile phone at a place above 10 ℃, or simply hold it in your hand. Generally, the mobile phone can be turned on normally in about 5 minutes, and the battery will recover soon.
3. Rub the back of the phone with your hand
Primitive wisdom tells us that drilling wood can get fire, so quickly rubbing the back of the mobile phone battery with your hands to generate heat can also raise the battery temperature? The answer is' the ideal is very plump, the reality is very bony '. The heat brought by rubbing will soon be diluted by low temperature. Before the speed and temperature of hand rubbing rise, the heat generated before has disappeared. People will be tired to death before rubbing the lithium battery to completely restore the power.

4. Wear a thick mobile phone case
The mobile phone case can slow down the power failure of the mobile phone, which is the same as wearing clothes. When there are more clothes, the temperature will rise naturally, and the power failure speed of the lithium battery will also slow down. But generally, mobile phone cases are made of plastic or materials without any thermal insulation function, so it's really a little unreliable to prevent power failure. But you can also try the plush version of the mobile phone case, as long as you are not afraid to be said too Niang.
5. Stick a warm baby
Not to mention that someone really does this, warm baby is a magical equipment and a 'fire in winter'. Warm baby paste people can quickly generate heat, so can you paste mobile phones? The answer is really not very good.
The average release temperature of warm baby is 53 ℃. Although it does not reach the upper temperature limit of 60 ℃ of lithium battery, in the actual test, if it exceeds ℃, there may be a prompt of too high temperature and failure to start up, so this method is not desirable.
6. Warm yourself
Human body temperature of 36 ℃ is the most suitable for warming mobile phones in winter. Of course, you must not think that it is too cold if people have zero distance contact with mobile phones. Putting the mobile phone in the interlayer of clothes or in the pocket of thicker clothes can revitalize the battery. The closer to the body, the faster the battery recovers. Of course, after recovery, taking out the mobile phone to make a call will still freeze. The mobile phone has no power, but fortunately, it will persist for a while.
7. Charging with mobile power
This is a misunderstanding. Many people think that the reason why the battery can't be turned on in winter is that the battery is dead. In fact, the battery has electricity, but the protection of the battery makes it impossible to supply power. So no matter what you charge at this time, it won't help, including the mobile power supply. When charging, it will prompt that the temperature is too low.
4、 What should we pay attention to after power failure?
There is nothing wrong with your mobile phone. It must not be broken, so don't worry.
After the power of the mobile phone is restored, it may lose power. Even under normal conditions, the battery power will change and generally decrease from the time when the phone cannot be turned on when the temperature returns to normal.
Never bake the phone at high temperature. This is a very wrong way, including putting the phone on the radiator.
