The battery level of my HUAWEI phone/tablet changes dramatically or the battery level display is abnormal

The battery level is not displayed in real time on the AOD screen

The battery level displayed on the lock screen may be different from that displayed after the screen is unlocked. This is a normal phenomenon.

The ambient temperature is too low

It is normal that the battery drains more quickly when running power-intensive apps (such as taking photos, recording videos, and playing games) at low temperatures. It is recommended that you use your device at an ambient temperature of 1°C to 35°C.

If your phone/tablet has just been powered on, has a low battery, or has been idle for a long time

Your phone/tablet may automatically calibrate its battery level, and the displayed battery level may be adjusted within a certain range. Your phone/tablet will return to normal after a few charge-discharge cycles. This is normal and does not indicate an issue with your phone/tablet.

The battery is aged

This accelerates the deterioration of the battery. In this case, the battery level may decrease rapidly. For a better user experience, it is recommended that you replace the battery when the battery health（Settings > Battery > More battery settings (or Battery health) > Maximum capacity） is lower than 80%. You can call the Huawei customer service hotline or go to an authorised Huawei Service Centre for assistance.

If the issue persists, back up your data and take your device and proof of purchase to an authorised Huawei Customer Service Centre for assistance.
