My HUAWEI watch's battery level changes suddenly after it is updated

Problem

After the watch is updated, the battery level changes more noticeably than usual, with sudden drops or increases.

Solution

This is normal and does not indicate any issue with your device. The possible causes are as follows:

• Generally, the watch's battery level may drop to different extents depending on the update duration (for example, the size of the installation package can affect how long it takes to decompress the system update files). However, if the watch remains on the charger during the update, the battery level after the update may even be higher than before.
• During the firmware update related to battery power, the watch's battery health software will apply targeted optimisations, which can also cause changes in the battery level.

If the issue persists

If the watch's battery level frequently changes in addition to the above issues, there may be a hardware fault. In this case, back up your data and take your device and proof of purchase to an authorised Huawei Customer Service Centre for assistance.
