The newly bought Apple xr only took 4 months, and the battery capacity was 98?

Apple has such a warranty. During the warranty period, if the battery wears more than 20%, it can be replaced with a new battery for free. What happens when the battery is exhausted to 80%? The most intuitive problem is that users will obviously feel that the standby time is shortened. Assuming that it is charged once a day, when the loss reaches 80%, it may be charged twice a day. Apple's design requires that the normal battery loss frequency should be no less than 80% of the maximum battery capacity after 500 charge and discharge cycles. According to this requirement, the remaining 98% of the battery is normal after three months of use.

With the increase of cycle times, the lithium battery of Apple mobile phone will suffer irreversible loss. According to Apple official website's information, the capacity of the lithium battery of the iPhone can still be more than 80% after 500 cycles, so if you are a moderate user of the iPhone, then 20% of the battery capacity of the iPhone can generally be used for about 1-2 years. According to 500 cycles and the remaining 80% battery capacity, it seems a bit abnormal for iPhone XS to use 96% battery capacity for two months, unless it is a heavy iPhone user. Look at other Apple XS users. After using 1-2 months, the power consumption is generally 1%-2%. Of course, there are also some iPhone XS users whose battery capacity is still 100% after two months of use.

The battery is healthy, that is, with the long-term use of the iPhone, the maximum capacity of the battery will gradually decrease. If the battery capacity is less than 80%, the processor frequency of iPhone will be reduced, and the direct impact is that it will be stuck; If you just brush your circle of friends or watch Weibo, the performance requirements for daily use are not high, then the lower battery capacity can still be used; However, if you often play games in daily use, it is suggested that you can change the battery with your mobile phone when the power is reduced to about 80%.
