If the loss exceeds this range, it may be that the mobile phone is out of order. As soon as Apple's mobile phone is used, the battery will start to wear out. The life of Apple's mobile phone is not only related to the battery quality, but also related to the charging times of Apple's mobile phone.
Generally speaking, after a year of normal use of the iPhone, the battery health value should still be above 90%. There is a simple criterion to distinguish it:
1. If there is more than 95% left, it proves that you have very good charging habits and usage habits.
2. If there is more than 90% left, then your charging habits and usage habits are passable.
3. If it is less than 90%, then you should think about whether there is something wrong with your usual charging habits and usage habits.
If it is less than 80%, I want to congratulate you. You can replace a brand-new battery for free.
Related precautions
The number of cycles of the battery is limited. When we are using the iPhone, we must never recharge it when the battery is exhausted, because this deep discharge and recharging will cause irreversible damage to the battery health. After a few more experiences, we will see that the battery health value has dropped significantly.
The same is true for charging. Don't charge the battery to 100% every time. More than 80% is enough. If possible, we should develop the habit of charging and discharging and try to keep the battery at 20%-85%, which can effectively prolong the service life of the battery.
