Set Up Bedtime Mode auf OnePlus
Bedtime mode is part of Digital Wellbeing on OnePlus phones running Android with OxygenOS. It links two separate system functions, screen grayscale and Do Not Disturb, to either a clock schedule or your charging pattern, so neither has to be switched on manually.
Without this setup, grayscale and Do Not Disturb stay independent toggles that reset once you unlock the phone or leave the charger. That is why notifications keep arriving in full color at night even if you turned Do Not Disturb on the evening before.
To configure it: Open the Settings ➔ Tap on Digital Wellbeing & parental controls ➔ Tap on Bedtime mode ➔ Choose Based on schedule or While charging at bedtime ➔ Tap on Customize ➔ Enable or disable Do Not Disturb or Grayscale.
Based on schedule lets you pick start and end times plus specific days, useful if you go to bed at a consistent hour. While charging at bedtime activates the mode as soon as the phone is plugged in overnight, which fits an irregular sleep routine better.
If you only want silence without the grayscale effect, disable Grayscale in the Customize screen and leave Do Not Disturb on. Screen calls and starred contacts still need to be allowed separately inside the Do Not Disturb settings, otherwise urgent calls get blocked too.
