Step 2, according to the daily usage, charge the battery when the usage is less than 5%.
This method can make the battery charge circularly and correct the problem of excessive battery consumption. If the above methods can't solve the problem, it may be that the battery itself needs to be replaced at the official maintenance point.
The method of repairing iPhone battery life through battery calibration is as follows:
1. First fully charge the iPhone.
2. Use less than 5% battery before charging.
The above operation is called charging cycle. Usually, a complete charging cycle can correct the problem of excessive battery consumption. Of course, if this method still doesn't work, it may be that the battery life is not good. If it is still under warranty, you can go to Apple to replace it for free.
