1, H2OS enters Settings-Battery-Battery Optimization, and turns on the battery optimization switch that is not commonly used; Color OS setting path: setting-battery-more-abnormal power consumption optimization, automatic optimization when background applications consume too much power, and prolong power consumption time.
2. The brightness of the screen is the brightest, and the rest time of the screen is long, resulting in fast power consumption of the mobile phone. It is suggested to turn on the automatic adjustment function of screen brightness to reduce the power consumption of bright screen;
3. There are too many background programs running, resulting in fast power consumption of the mobile phone. It is suggested to clean up the background programs of mobile phones, so as to reduce the power consumption of background applications.
If the problem still exists after trying the above methods, I suggest you apply for after-sales service, and the network engineer will detect and handle it for you.
