iPhone 15 alarm stops after just a few rings

Hello mvinson1968,

Thanks for using the Apple Support Communities!

By default an alarm should continue to ring until you either disable it or snooze it. This may be different if you have a feature like Attention Aware enabled.

You can check if you have that enabled in Settings > Face ID & Passcode > Attention Aware Features.

Hope this helps!

The solution is simple but not obvious ….

in Face ID switch off attention aware features !

why the dont Apple tell us this, I have been searching for a solution for months.

Big black mark for Apple who ignore us - their clients and income

My iPhone 15 Alarm will ring one time only.

My iPhone alarm only rings once and then goes silent
