Power consumption increases after a system update

Power consumption increases after a system update

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:

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.

Solution:

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.

If the problem persists, it is advised that you search for "The phone's battery drains quickly and has a short standby time" for further troubleshooting.

It is advised that：

After the first upgrade is completed, turn off the screen and charge the phone for more than 2 hours, then restart the phone to ensure that the installed applications in the phone have been optimized;
Clean up the background applications in time when the mobile phone is not in use;
When not using GPS, Bluetooth, and NFC, these can be turned off to achieve the purpose of turning off the screen and saving power;
In the Google Store, turn off the automatic update of the application connected to wifi in the settings; because when the switch is turned on, the Google application will automatically update the application, resulting in power consumption.
The specific operation is as follows: Google play>account icon in the upper right corner>settings>network preferences>automatically update applications>do not automatically update applications
