I accidentally flooded the iPhone, so remember not to make any button actions. Some friends quickly turn off the phone when the phone is flooded. This is a wrong approach. Once you press any operation, the water will immediately follow the circuit board. When the phone gets water, the correct way is to open the outer cover, take out the battery of the Apple phone, and directly force the phone to power off to ensure that the motherboard is not damaged by water.

　　When the battery life of the Apple mobile phone is significantly shorter, some small partners will directly buy a new battery to replace or replace with a new mobile phone. In fact, you can try the following methods to bring the battery of the Apple mobile phone back to life.

　　1. Wrap the battery with newspaper, then put it in a plastic bag and put it in the refrigerator for three days, the newspaper can absorb moisture;

　　2. Take out the battery after three days and place it for two days in a normal temperature environment;

　　3. After two days, fully charge the battery and install it in the mobile phone for testing. The capacity is estimated to be 80%-90%.

　　This method was proposed by an engineer from a well-known battery manufacturer. As for whether it is really effective, it is better for you to try it.
