How to maximize the battery life of a used iPhone


You may have just finished a game or watched the last part of the movie, but the low phone battery alert sounded louder than it was. The battery capacity of an iphone is around 3000 mAh. Life is always a problem that has to be faced. Older phones don't mean batteries are old. But you also need to consider how to maximize the use of mobile phone batteries.

As described in the official website of major mobile phones: keep the software update, keep away from extreme temperatures, remove the protective case during charging, and save half of the power during long-term storage. The above four methods can effectively maintain the performance of the mobile phone battery. But the situation in life is more complicated.

There are 3 points that you should pay more attention:


1. When the temperature is controllable, use the phone when charging.

This eliminates the number of cycles of the phone battery and avoids deep battery discharge.

2. don’t use fast charger.

Whether it's an iphone or an Android phone, the original chargers are standard USB ports and have built-in protection chips. If a third-party nameless charger is used, in order to save costs and produce some chargers without a protection chip, some small accessory manufacturers may have the risk of power instability or excessive current, which may cause damage to the smartphone.

3. Use the original charger and do not run out.

 So there is no need to run out of the phone and recharge it. If the lithium phone battery is in a low voltage state for a long time, it may cause charging failure. So when the phone's power drops to less than 20%, it should be charged. If it is a mobile phone that is not used for a long time, it should be kept at full power and charged for a while.


Maintain your phone is always a good way to maximize the battery life, no matter a second hand iPhone or Huawei.
