Turn on Do Not Disturb in one tap

Go to Settings > Focus.

Then, tap the Do Not Disturb toggle to turn it on.

Do Not Disturb (DND) is a mode on your iPhone that silences all incoming calls, texts, and notifications. This can be useful when you're trying to sleep, focus on work, or just relax and don't want to be disturbed.

To turn on DND, you can either go to Settings > Focus and tap the Do Not Disturb toggle, or you can swipe down from the top of your screen to open Control Center and tap the Do Not Disturb icon.

Once DND is turned on, you'll see a moon icon in the status bar at the top of your screen. You'll also see a message on your lock screen that says "Do Not Disturb is on."

To turn off DND, you can either go to Settings > Focus and tap the Do Not Disturb toggle again, or you can swipe down from the top of your screen to open Control Center and tap the Do Not Disturb icon again.

You can also customize DND to allow certain people or apps to still send you notifications. To do this, go to Settings > Focus > Do Not Disturb and tap on the "Allowed Notifications" tab.
