How to refresh the battery health after Apple's mobile phone is replaced with a new battery?

1. Let the battery of the mobile phone be completely exhausted: Use the Apple mobile phone until the battery is exhausted, in which case it is best to charge it.

2. Fully charged: use the original charger to connect the Apple mobile phone to the power supply and charge it to 100%.

3. Restart the Apple phone: long press and hold the power button on the side, drag the "slide off" option, wait for a while, and then press the button to turn on the Apple phone.

4. Reset the battery health: Go to "Settings"-"Battery"-"Battery Health" in Apple's mobile phone, and the maximum capacity and peak performance counters of the current battery will be displayed on this page.

5. If the peak performance counter shows "Failed", you can choose to reset the battery health status. Select "Agree" in the warning message and verify it, then wait a few minutes.
