What if the iPhone7 plus suddenly shuts down?

There are generally three ways for iPhone7 plus to suddenly turn off the screen. The specific methods are as follows:

1, the first method, try to restart the phone, while holding down the power button and the HOME button to restart the phone until the boot sign appears.

2. The second method is to try to charge the mobile phone with a wireless charger, and then press these two keys at the same time. This is to detect whether the battery is automatically turned off because of sudden power failure. If so, you can charge it for a while before turning it on.

3. Third, the iPhone usually has a built-in liquid touch indicator, usually a white or silver dot, which will turn red or pink in whole or in part when it touches water. If this is the case, it can be sent to the designated maintenance point for maintenance. The above is the specific method to solve the sudden failure of iPhone7 plus.
