My Apple 4s charges and consumes super fast, sometimes more than 20%. If I turn it off and on by myself, there will be a picture of no power.

Mainly because of the battery, the battery is aging. Apple's 4S battery will maintain 80% of its original capacity after 500 cycles, and then it will rapidly reduce its capacity. Assuming that it is washed once a day, 500 cycles is one and a half years. (Many people often charge for more than one day) After 500 cycles, the battery capacity is not as good as before, and battery jumping will occur.

The method of repairing the battery life of iPhone4S 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.

Tutorial supplement: In addition, you can know the battery health of the iPhone by looking at the maximum battery capacity of the iPhone, or check whether the iOS device is normal by some simpler methods.
