How do you activate the battery of mobile phone which has no power?

The most common situation in winter is that the battery power of the mobile phone is not long enough. And the colder the weather, the faster the power will drop. I remind you to save some power to the phone in a cold place, otherwise the phone will automatically shut down when the battery is completely emptied, then the battery will sleep and can no longer boot. So how is battery sleep activated? What should I do if the phone does not turn on after the phone is turned off automatically?

How to activate the battery sleep after the phone is powered off automatically

First, use direct power to charge

The phone can't be turned on after the phone is turned off automatically. Don't worry about it at this time. The phone is actually not broken just because the power is running away, so it can't be opened. At this time, you can make up the electricity. I recommend using direct power charging instead of using a computer jack and a mobile power source, which are very slow to charge.

Second, recharge the battery after recharging

When the smartphone is turned off automatically and can't be turned on, it can be charged in a more suitable environment. The cold environment is easy to charge, and then the battery is reinserted. Sometimes this method works quite well. The charging light is on. At the beginning, the instructions have started to be recharged, and the patient will be able to start up after waiting for a while.

Third, use the universal charger to charge

Put the unpowered phone on the power supply and do not worry about turning it on. Because the power is also required to power on, if the charging still has no effect, then you can use the universal charger to charge the phone battery. It only takes a while for the phone battery to be reactivated. In this case, you can switch back to the original charging method.

Fourth, the metal wire is activated

Going back to the problem in step 2, now it's all smartphones. Very few people specialize in charging. It doesn't matter if there is no charger, in fact, two small wires can solve the problem. Find two wires and a battery with electricity, and connect the positive and negative poles of the two batteries in a staggered way to activate the dormant battery.

Five, charging for a while and then boot

No matter which way you activate the dormant battery, you can't turn it on. The boot requires a certain amount of power, even if the battery is barely charged with some power, it will soon be discharged when it is turned on again. It is recommended to turn on the phone after half an hour, then turn the phone into flight mode.

Get the mobile phone repair shop to activate

After trying all kinds of methods, I found that I still can't charge the battery. At this time, I have to consider whether the battery is broken. You can use the spare battery to see if the system is damaged if you still can't open it, otherwise the battery that is dormant can't be activated. There is a way to activate your mobile phone and there is no charge.
