The most common situation in winter is that the phone battery power is not long-lasting enough. And the colder the weather, the faster the electricity decreases. The editor reminds everyone to save some power to your phone in colder places. Otherwise, when the battery is completely depleted, the phone will automatically shut down, and the battery will go into sleep mode and cannot be turned on again. So how to activate battery sleep? What should I do if my phone automatically shuts down when it runs out of battery and cannot be turned on?

How to activate battery sleep when the phone automatically shuts down after running out of battery and cannot be turned on

1、 Charging with direct power supply

After the phone runs out of battery and automatically shuts down, it cannot be turned on. Don't worry at this time, the phone is not actually broken, but it cannot be turned on because the battery has run out. Just recharge at this time. The editor suggests using a direct power source for charging, rather than using a computer jack and a mobile power source, as the charging speed of the latter two is very slow.

2、 Recharge after reinserting the battery

When a smartphone automatically shuts down and cannot be turned on after running out of battery, first charge it in a more suitable environment. It is easy to not charge it in a too cold environment. Then, remove the battery and reinsert it. Sometimes this method is quite effective. When the charging light is on, it indicates that it has started charging. Be patient and wait for a period of time before turning it on.

3、 Using Universal Seat Charging

Place a dead phone on the power source to charge, do not rush to turn it on. Because starting up also requires electricity, if charging still doesn't work, you can use a universal seat charger to charge the phone battery. After a period of time, the phone battery can be reactivated, and then the original charging method can be switched back.

4、 Activation of metal wires

Returning to the issue in step 2, nowadays smartphones are mostly used, and there are few people who specialize in using seat chargers. It doesn't matter if there's no seat charger, actually two small metal wires can solve the problem. Bring two metal wires and an electric battery, and connect the positive and negative poles of the two batteries in a staggered manner to quickly activate the dormant battery.

5、 Charge for a period of time before turning on

No matter which method is used to activate the dormant battery, do not rush to turn it on. Starting up requires a certain amount of battery power, even if the battery is barely charged, it will quickly run out when it is restarted. It is recommended to charge for half an hour before turning on the phone, and then set it to airplane mode.

6、 Get the phone repair shop activated

After trying various methods, it is found that the battery still cannot be charged, so it is necessary to consider whether the battery is broken. You can use a backup battery to check. If it still cannot be opened, it may be due to system damage. Conversely, the dormant battery cannot be activated. There is a way to activate your phone at the repair location, and there is no charge.
