TL;DR
Mute noisy WhatsApp groups without leaving them: Group info → Notifications → Mute. You decide when you read groups (daily or weekly).
So geht’s
- Open the WhatsApp group chat.
- Tap the group name at the top (→ Group info).
- iPhone: Notifications → Mute → choose a duration (e.g., 8 hours, 1 week, Always) and turn off Show notifications (if available).
- Android: Mute notifications → choose a duration and disable Show notifications; optionally open Custom notifications and set sound/vibration to none.
- (Optional) Set Notify for to Mentions only if you still want @mentions without every message.
- Pick a schedule: check groups on your terms (e.g., once a day at 17:00 or once a week).
Why this helps
Fewer interruptions, same context: you stay in the group but control when it gets your attention.
