Why Your Alarm Still Rings in Silent Mode

Tap a topic to see the explanation.

iPhone

The alarm app is designed by default so that a set alarm still sounds normally even when the mute switch is turned on.

Android

Do Not Disturb settings usually allow "Alarms" as an exception by default, letting them ring even while everything else is silenced β€” it is still worth double-checking this in your settings.

Check alarm volume separately

Some devices separate media volume from alarm volume, so if your alarm doesn't ring, check the alarm-specific volume slider rather than only the media volume.

If it still doesn't ring

A battery saver mode can sometimes restrict even an alarm app's background activity, so try adding your alarm app to the battery optimization exclusion list.

Alarms are built to override silent mode

Because a missed alarm can mean missing something important like work or a flight, most phone operating systems deliberately design the alarm feature to bypass the mute switch and Do Not Disturb settings, treating it as a special exception among notifications.

Double-check before an important morning

Even with these built-in protections, a rare combination of a battery saver mode, a separate alarm volume set too low, or a customized Do Not Disturb rule can still cause an alarm to fail silently. Before a morning you truly cannot afford to oversleep, it is worth doing a quick test alarm the night before.

Frequently Asked Questions

My alarm didn't go off even though the volume was turned up.

Check your battery saver settings, any custom Do Not Disturb exceptions, and the alarm volume slider separately from your media volume, since one of these is usually the cause.

Does Do Not Disturb block alarms?

By default, no β€” alarms are treated as an exception. However, it is worth confirming this in your settings if you have customized your Do Not Disturb rules.
