The reaction of the battery is hydrogenation reduction reaction. If there is charge, there will be discharge, but don't overdischarge the battery. Therefore, you'd better charge your mobile phone when it keeps a certain amount of power, and don't always charge it when it is dead. When the battery is completely exhausted, try not to charge it. Charging when using is good for battery life.
2, the use temperature
Temperature will also affect the health of the battery. At high temperature, the diffusion of hydrogen ions and sulfate ions in lithium polymer battery will accelerate, so the discharge capacity of the battery will increase, which is also the reason why the battery life will become worse at high temperature.
Of course, at low temperature, the temperature will also hinder the diffusion of ions and other substances, and the battery discharge speed will slow down, but the mobile phone will be stuck. If the battery has temperature protection function, the phone may also be turned off directly. Generally speaking, the optimal operating environment temperature of iPhone is about 0℃-35℃.
Extended data
The health of the iPhone battery is also related to the way users use it. Simply put, the battery is a consumable, which is related to the user's usage besides poor maintenance. For example, daily heavy use, often used to play games or watch videos. Long-term high-load use, battery loss is relatively large, plus charging several times a day, long-term accumulation will undoubtedly have a great impact on battery health.
Users who use it lightly can basically charge once a day, and the battery loss is relatively small. Combined with battery maintenance, it is more conducive to maintaining the battery power of iPhone and stabilizing it at a high percentage.
