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?

I've actually watched the alarm go off but it did not vibrate NOR sound. The thing is, I have set like 5 alarms for the AM. It is weird considering that some alarms actually do sound, but one or two do not.


I've read the suggestions:


Confirmed: Do Not Disturb is NOT on

Confirmed: Not connected to any bluetooth device

Confirmed: Each alarms is set to sound

TWENTY PAGES Apple!?!


I bought the original iPhone, one for my wife, one for me. I've had one ever since. It blows my mind that this alarm bug has existed, in some form or fashion, since the first one. I just had it happen this morning again. Three alarms, the last one went off AFTER I checked under sound and haptics and confirmed my volume is set at half in there. Both silent and non-silent are set to about half. While the alarm is going off, I can switch the slider from silent to normal, and the alarm tone appears. I switch it back, it goes away.


It's sad, I literally have a new phone coming today to replace my old one, and I bet it still has this issue.


Apple, get it together.

The following suggestion "Attention Aware Features" was turned on. When I turned the feature off, alarm started working as normal. To turn it off go to Settings-->Face ID and Passcode--> Attention Aware Features = off" is not available on my iphone 8, IOS 13.4.1, thus I still have the problem of intermittent correct working of the alarm.

I am so relieved to find out that I’m not going crazy!!! Yipee! I’m not the only one with this problem... This is a big Issue and I really must find a solution. Do I really need to get a different alarm clock because My IPhone can’t handle it? I have always been an Apple enthusiast, but this is a MUST FIX for apple. This has cost me dearly on several occasions.

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).

I solved my issue. Some times my alarm would show its going off but no sound and then my other alarms wouldn’t go off.


This caused me many headaches from being late.


My problem was that if you have multiple alarms set but you don’t have snooze activated on them and you stop the first alarm with the volume option than it will not sound any of the other alarms that you have set unless one has the snooze option on.


Make sense? Hope I helped

Same issue for me this morning (and not the first time). Here’s a screen shot of my phone screen after I hit snooze. Normally it’s a 9 minute timer. That 9 minutes had elapsed, and was now counting up (note the negative sign in front of the timer). The phone alarm did initially sound, and I got snooze, but the snooze today was silent. Also to note: “Bedtime” do not disturb schedule is scheduled to end at 5:30am. It still was on at 7:17am.


This is a bug, not user error with the volume settings. Apple, please look into this and feel free to contact me for the logs off my phone.User uploaded file.

You are correct. Apple engineers and developers do not regularly monitor the forums. You can either contact Customer Support who, even if they cannot help you, will log the issue.

I believe that very fact has been mentioned several times in this thread. This is a user-to-user forum. Apple's participation is limited. You can contact support using the "Contact Support" link in the upper right corner of every page of these forums.
