Sleep schedule alarm no sound. Only Apple Watch vibrates.

Thanks for getting back to us. We're sorry for the delay in our response. If you have the alarm set up in the Sleep settings on the iPhone, the alarm will only sound on the Apple Watch. If the Apple Watch is in silent mode (this is done by touching and holding at the bottom of the screen, swipe up to open Control Center, then tap to turn on silent mode) the Apple Watch wakes you with taps, but no audible alarm. If you want an alarm to sound on the iPhone, you will need to add an additional alarm outside of the Sleep settings.

Hope this helps.

Best Regards.

Hello Lando13,

Thanks for using Apple Support Communities! We understand you're having issues with not having an audible alarm when using your Apple Watch and the Sleep alarm; let's look into this more.

Sounds like you have the Wake to haptic taps feature enabled. You can see more about this feature here:

Track your sleep with Apple Watch - Apple Support

Specifically, check out the section labeled "Change sleep options"

Hope this helps.

Best Regards.

I have a similar problem. I charge my iPhone 12 Pro and watch at night, so I am not wearing the watch to bed. My alarm (set in Sleep/bedtime settings) in the morning does not go off. When I do eventually wake up and look at it, it shows the screen to dismiss the alarm with snooze or stop, but the sound isn’t going off. The sound is turned all the way up on my iPhone, no idea what’s going on. I’ve set an additional alarm outside of the Sleep/bedtime Settings for tomorrow since this has happened for a few days now, as a back up but would really like to know why it’s not working?
