iPhone alarm is silent randomly

Hi everyone,

Since a few weeks it happens that my alarm clock doesn't come on with sound every time. When I wake up and set it just for checking, it rings again. It happened about 5 times, one time I woke up while it was alerting, but only the screen showed the alarm.

I really depend on this alarm clock but I can not trust it anymore :-( what to do?

My alarm was also going silent after a single alert. Just started doing this after I got a replacement and figured out that it was because "Attention Aware Features" was turned on. When I turned the feature off, alarm started working as normal. I think the feature turns alarm to silent as soon as I move it or it recognizes my face ID.


To turn it off go to Settings-->Face ID and Passcode--> Attention Aware Features = off

I have resolved this issue for me at least by following these steps:

  1. Go to Settings/Sounds
  2. Ringer and Alerts was set to zero volume, Change with Buttons disabled
  3. Not sure how this happened but it meant that no sound would come out on any Alerts or Alarms. And setting the volume to maximum would have no affect
  4. Set the volume to the level you want - you can leave Change with Buttons as disabled (which is useful because the volume of Alarms can remain quite loud even if your volume is down low the night before).

Yes, that is definitely the issue for some people. Unfortunately, not for all.

I’ve had the same issues with my iPhone X.

The entire phone goes into a silent state.

Even the lock click doesn’t make a sound.

Videos don’t play noise on Facebook. The entire device is silent.

I had this issue this morning. Not for the first time. If it wasn’t for me setting my iPad as well as iPhone I’d be late for work because of a bug that needs to be fixed.

A phone should not be turning itself into a silent mode overnight.

I also noticed my iPhone asked for my passcode.

Which only happens when the phone is rebooted.

Which I didn’t do.

So comes to question... Is my iPhone restarting itself during the night as well?


This issue needs resolving. It is a major need in people’s lives.

I I am having the same problems. Alarm sound not working, randomly the phone goes into silent mode on videos on different social media platforms.

Have to resart the phone in order for it work.


This my 8th iphone I have owned and you expect the latest X-phone alarm to work, so annoying,
