According to the theoretical reference value given by Apple, the maximum capacity of the iPhone battery is less than 80%, which means that the battery can no longer provide the necessary peak power for the iPhone. At the same time, the battery health will enter the maintenance state, telling the user that it is time to replace the mobile phone with a new battery.
Therefore, once the habit of playing with mobile phones while charging is minimized in subsequent use, even if the maximum battery capacity is 87%, users can be allowed to use the iPhone for one and a half years. On the contrary, an iPhone with a maximum battery capacity of 100% will actually wear out quickly under the operation of bad habits.

Precautions for using mobile phones:
Charging time should not be too long, which will seriously affect the battery life and increase the probability of danger. You don't need to charge12h for the first time.
The first new mobile phone does not need to wait for the phone to be turned off before recharging, which will cause great damage to the battery.
Some automatic intelligent fast charging displays 90% full only when the signal light changes. The charger will automatically change to a slow speed to charge the battery. It is best to use the battery after it is fully charged, otherwise the service time will be shortened.
Try to avoid charging before going to bed, because the charging time before going to bed is long and the voltage is unstable at night. In many places, the voltage is relatively high at night and fluctuates greatly, which has a great influence on the battery.
