It is inferred that the subject is not because of water and dropping the phone, which causes the phone to not turn on.
If it is because of battery problems, it may be one of these three situations.
1. The boot circuit is abnormal 2. The power supply circuit of the battery is abnormal 3. The IC of the mobile phone power supply is abnormal.
In this case, you need to apply for after-sales repair.
It is not caused by battery aging and other reasons, you can try this method, press and hold the "power button" and "volume + button" at the same time to force the power on, if the shutdown is not caused by hardware damage problems, it can be turned on.
