Apple has been charged 900 times and has a battery life of 86.

86% battery life of Apple mobile phone can be ignored for the time being, but the choice should be decided according to actual needs. If 86% of the batteries are not durable, you can also consider replacing them with new ones. When the battery life is less than 80%, the battery must be replaced. Under normal circumstances, the battery of iphone can last for two years.

When the charging cycle of iPhone reaches 500 times, the battery capacity will drop to 80% of the initial charging. When the battery life is less than 80%, in order to prevent accidental shutdown and extend the battery life, Apple will avoid high-load operation of the mobile phone and reduce the frequency of the iPhone. At this time, you will obviously feel that the fluency of your mobile phone is declining, and you can't play games in Quan Huafu, which seriously affects your personal experience.

Therefore, if you find that the battery health of iPhone is lower than 80%, it is recommended to replace the battery. This is not only for the sake of endurance and performance, but also for the sake of safety.
