What does it mean that Apple's mobile phone suddenly shuts down automatically? I didn't escape from prison, the system was updated to the latest, and recently I opened Youku and other software to get stuck directly. 1. Maybe it's just running too much software in the background.

2. In addition, it may be that the running time is too long and the phone is cooling down.

Causing the phone to crash and passively shut down.

3. Perhaps it is a self-protection mechanism initiated by Apple's mobile phone.

Just restart.

4. If a black screen appears after the upgrade, it may be a system compatibility problem.

It may conflict with some software, so we have to turn off some useless software.

If you can't do the above, you have to brush the machine to the factory setting.
