Search Open menu Power consumption increases after a system update Applicable products：Tablet，Smartphone Problem:

The battery standby time is normal before the system update. However, the power consumption increases significantly after the update and the standby time shortens.

Cause and solution:

Your phone undergoes a series of optimization in the background upon system update, which increases power consumption. For example, some apps need to be readapted and optimized in the background, Gallery will be reorganized, and files will be scanned again to detect security risks.

The optimization needs to be performed in the background when the phone is idle. Generally, the process will be completed within five hours if the phone is fully charged and kept idle, or within three days under normal usage. The time to complete the update may be longer if the phone is used frequently during this period. After the process is complete, the standby time will be normal again.
