Huawei Battery Health 99 refers to the "maximum capacity" display status in Huawei mobile phone settings, that is, the battery capacity relative to the new battery. Techniques such as using dark mode, closing unnecessary applications, reducing screen brightness, reducing vibration feedback, and not charging the battery to 100% are mainly divided into software settings, charging methods and usage habits.
If used correctly for one year, the capacity can reach more than 90%. The battery will not only directly affect the battery life, but also affect the performance of the mobile phone.
