1. In daily use, it is best not to use the automatic shutdown of the Apple mobile phone, but to charge the mobile phone when the power of the mobile phone is used up to 20%-40%, and it is best to unplug it when it is full.

2. Early mobile phones used nickel-cadmium batteries and nickel-hydrogen batteries, and nickel-cadmium batteries and nickel-hydrogen batteries required similar "activation."

These batteries will produce a "memory effect". Charging in an incompletely discharged state can easily cause the battery to be overcharged. After a long time, the user will feel that the battery will run out quickly. Therefore, it needs to be fully charged for 12 hours for the first time. It’s best to use it to recharge when the battery is dead.

3. The battery used on the iphone is a lithium ion battery. Its initialization process has been completed at the time of manufacture, so it does not need to be activated when it starts to use. The lithium battery also has no memory effect and can be charged at any time. If the mobile phone is automatically shut down, the internal voltage of the lithium battery will be too low due to excessive discharge, and it may not be able to turn on and charge. Therefore, the charging of lithium batteries pays attention to "eat less and more meals", and frequent shallow charging and discharging are more helpful to prolong its life.
