Sleep settings are no longer locked in Windows 11 so you can configure device sleep timers that suit your device usage pattern. Devices will still auto lock after 10 minutes of idle
The default sleep timers are as follows
- On Battery
- Screen off after: 3 minutes idle
- Device sleeps after: 3 minutes idle
- On power
- Screen off after: 5 minutes idle
- Device sleeps after: 5 minutes idle
If you would like to change these defaults you can do so by going to Start Menu > Settings > System > Power & battery > Screen and sleep
