Get help with alarms

Do Not Disturb and the Ring/Silent switch don't affect the alarm sound. If you set your Ring/Silent switch to Silent or turn on Do Not Disturb, the alarm sound still goes off.

If you have an alarm that doesn’t go off, is too quiet, or if your iPhone only vibrates, check the following:

  • Check the volume on your iPhone. If your alarm volume is too low or too loud, press the volume button up or down to adjust it. You can also go to Settings > Sounds & Haptics to adjust the volume.
  • If your alarm only vibrates, make sure that your alarm sound isn't set to None. Open the Clock app, tap Alarm, then tap Edit. Tap the alarm, then tap Sound and choose a Sound.
  • If you use iOS 10 or earlier and you connect headphones or speakers to your iPhone, the alarm plays through the connected device instead of the built-in speakers.
  • If you use iOS 11 or later and you connect headphones or speakers to your iPhone, the alarm plays at a set volume level through the built-in speakers on your iPhone. It doesn't play through your headphones or speakers.

Manually adjusting your iPhone’s time in Settings to change app behavior, like game timers, isn’t recommended and can affect alarms.
