Set Screen Timeout auf Huawei
When a Huawei phone locks itself faster than expected, or stays awake long after you put it down, the Sleep timer in the display settings is almost always responsible. This value decides how many seconds or minutes of inactivity trigger standby mode, independent of whatever app you had open.
Open Settings ➔ Display & brightness ➔ Sleep and pick a duration between 15 seconds and 10 minutes. Shorter values save battery and reduce accidental taps while the phone sits in your pocket. Longer values keep the display active while you read or follow instructions without touching the screen every few seconds.
If you have a lock screen password, PIN, or fingerprint configured, every standby locks the device. A short Sleep timeout combined with a secure unlock method means you authenticate more often throughout the day. Some people deliberately choose a longer timeout to cut down on repeated unlocking, accepting a bit less battery life in return.
This setting only governs idle standby. It does not control how quickly the screen dims during video playback, calls, or navigation, since those use their own screen-on logic. If the display still turns off during a video, check that app's own settings or the battery optimization list instead of adjusting Sleep again.
