iPhone alarm is silent randomly

I think I know what the issue most people are encountering is... Basically if the screen fades to black after an alarm goes off pushing the 'home' button to wake the screen makes the alarm go completely silent while it waits for the user to select 'Snooze' or 'Stop'. It stays silent indefinitely. This is a massive design flaw in my opninion and has NOTHING to do with volume settings but nobody seems to have put their finger on the issue. I've woken up late countless times before I worked this out and it has been the same across many versions of iOS.

If this issue doesn't get resolved soon I really hope people would resist the urge to flood similar threads with suggestions of checking your volume and settings. I think it's safe to say most people would be smart enough to do this and it seems to have created an air of doubt around anybody who has experienced the issue MANY TIMES OVER MANY YEARS! I guess if you are a super chirpy morning person this will never happen but if you sleep heavy it's VERY EASY to do this by accident thinking you have hit snooze. Apologies for the tone but I find this issue and most of the threads addressing it very infuriating.

JS656, When you go into the main "Settings", scroll down until you find "Sounds and Haptics" and select that menu, then look for "RINGER AND ALERTS", and see if your volume scroller is set for maximum sound, or set for mute. That sound level is separate from your main sound levels. And if you don't want the volume buttons to alter your Alert Volume settings, then make sure the "Change with Buttons" is turned off.

yes! i am having the same exact problem , i set 2 alarms every morning and one keeps failing on me! it’s ridiculous. tbh there’s a lot of little technical issues i’ve had with my iphones over the past year or so splintered switching back to apple, issues i never had with my galaxy.. 🤔

Make sure that the alarms are not too close together. There appears to be an issue where, if you snooze the first alarm and, while it's snoozed, the second one goes off, the second one won't sound and the first one might not sound again.

Did you set up your current phone from the back up of your SE? If so, there may be something corrupted in the back up. I'd suggest restoring it as new and testing.

In my case it's realated to apple watch. If alarm "rings" when I'm wearing watch it's silent and every alarm after this will be silent no matter what. If rebooted its okay.

FIXED MY PROBLEM! Phone ringer dimmed after a few seconds. https://appletoolbox.com/iphone-xr-xs-x-ringer-or-alarm-volume-too-low-check-this-one-setting-to-fix-it/

I’ve noticed that a calendar notification that is issued at the same time as an alarm will cause both of them to be cancelled out (i.e., the alarm will not sound and the notification will not be displayed). I do hear a very truncated sound which can easily be missed.

I don't know if this is a known problem.

Try this work around: Set your alarm a few minutes before or after the hour, quarter hour or half hour (assuming most calendar events start on the hour, quarter hour or half hour, then most alerts will occur at these times also and this conflict will be avoided). I do not know if any other app alerts cause this problem with alarms.

I hope this helps.

Well not that the alarms themselves overlap but if you snooze the first alarm until the second one goes off, that’s when I run into problems. Say, my 745am alarm goes off, I snooze it twice, this means that my 8:00am alarm will not make the sound and only show up as the alarm on screen. Just personal experience! I guess this is a good way to tell me to stop snoozing my alarm! Ha

I’ve had this same problem. I have class at 9 every morning and have about 6 alarms set for the hour between 7:30 and 8:30.

Are you snoozing any of the alarms? If so, that could be part of the problem. If the snoozed alarm goes off at the same time as the next alarm, they may both be silenced.

Is it possible that the alarms only go off for a certain amount of time before they silence? I’m not sure but I’ve missed way too much stuff to rely on this again

If the alarm is working correctly, it will continue to go off until you turn it off.

Try deleting all of the alarms. Then set up one or, at most two. Test.

Edit:

I just performed a test and was able to replicate a scenario where the alarm goes off but is silent yet remains shown on the screen. I set up an alarm to go off on my phone. Immediately once the alarm began sounding on my phone, I called my phone with my wife’s phone, and her call muted my alarm but the alarm remains on screen. I repeated this test multiple times and got the same result. I did some more testing, and found that putting the phone into “do not disturb” mode will not interrupt my alarm. Hopefully this works when receiving texts or other notifications as well.

You say that you transferred the alarms from a previous phone. Try deleting all of them and re-adding them.

Just did chat again. Recommended resetting my settings. Will try again later.

i started closing all of my apps every night before I sleep about 6 weeks ago and have not had the silent alarm since.

Should not have to do this, but it works for me.

Close all apps before you sleep. This was my fix. Zero problems with alarm since I started doing this a couple months ago.

So far , the 13.1.3 ios update has prevented the recurrence of this issue on my iphone x. 13.1.2 still presented a problem and I was ready to switch away from iphone.
