Short answer

Go to Settings, Digital Wellbeing & parental controls, Bedtime mode. The setup turns on Do Not Disturb for bedtime, then sets Start and End (23:00 to 07:00 by default) and the days. Tap Done. Customise adds greyscale, a dimmed wallpaper and more.

About this guide

Bedtime mode silences the phone and makes the screen dull at night.

The screenshots are from our OnePlus Nord 5 with OxygenOS 16.0.5.1201 and Android 16, in Dark mode. We went through setup and looked at Customise, then switched nothing on: the page still said Bedtime mode is off.
