The battery drains quickly when Face Unlock is enabled
| The battery drains quickly when Face Unlock is enabled |
Problem:
The battery drains quickly when Face Unlock is enabled.
Cause:
Wake device or Raise to wake is enabled by default when you use Face Unlock. In this case, the screen wakes up whenever you pick up the phone. As a result, the phone battery drains quickly.
Solution:
Open Settings, search for and access Wake device or Raise to wake, and disable it to reduce unnecessary screen power consumption. To use Face Unlock, press the Power button to turn on the screen and initiate face recognition.
