Adjust General Sound Settings

Next, check some general sound settings on your iPhone:

  • Go to Settings > Sounds & Haptics and make sure the Ringer and Alerts volume slider is turned up adequately
  • Ensure your phone is not silenced – the side/mute switch should be in the up/unmuted position
  • Confirm Do Not Disturb is not activated, which can block alarms
  • Go to Settings > Focus and check alarms are allowed in your currently enabled Focus mode

Adjusting these sound configurations can override any issues of alarms being silenced or muted system-wide.

Restart Your iPhone

Restarting your iPhone is a quick way to clear out any minor glitches that may be preventing your alarm from going off properly.

To restart an iPhone 8 or later:

  • Press and release the Volume Up button
  • Press and release the Volume Down button
  • Finally, press and hold the Side button until you see the Apple logo

This refresh kills any stuck background processes or corrupt data that could disrupt the alarm functionality.

Update to the Latest iOS Version
