Having a correctly set iPhone alarm is handy in keeping your sleep schedules regular – it will wake you up at an appointed time. However, sometimes, it can fail to ring or sound.

The iPhone volume does not affect the alarm. Your alarms will sound at the appointed time even if the iPhone is set to DND (Do Not Disturb) mode. However, your iPhone should be turned ON and the alarm activated.

Keep reading, as this article will help you understand whether or not your iPhone volume affects the alarm. You will also learn how to fix your iPhone alarm if it fails to ring or sound.

Will the Alarm Sound When My iPhone is in DND (Do Not Disturb) Mode?

In the default behavior, the iPhone’s Do No Disturb mode turns off notifications and calls, but it keeps any set alarms active so they will ring to wake you up at the right time.

As long as your iPhone is powered on and the alarm activated, your alarms will sound at the appointed time, even if the iPhone is set to DND (Do Not Disturb) mode.

This is reassuring as you might wish to turn your iPhone to DND mode overnight, so your iPhone will not disturb you while you are sleeping but still want your alarm to wake you up at the right time.

Will the Alarm Sound if My iPhone Runs Out of Battery?

The alarm you set for the morning will not sound if your iPhone runs out of power and goes off during the night.

This should not worry you since iPhones are excellent at holding their battery charge if you are not using them, especially when you enable the Low Power Mode.

So, you will hear the alarm sound if you have around at least 15% battery left at the time you are bedding down.

However, if you are bedding down for an 8-hour sleep with battery power less than 5%, there is a high chance it will run out of juice during the night. So, you will probably not hear the alarm sound.
