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

Im glad (but not really because it sucks) to see other people having this issue, I thought I was going crazy! I switched from a 6s to an Xr a while back, and the alarm on my new phone would go off, and then after I pressed snooze it wouldn’t make sound again. When I woke up, an hour after I was supposed to be up, I could see the alarm on my screen, but no sound. I started using my old phone as an alarm clock, having to keep two phones plugged in and charging, but it has now updated to the new iOS and this morning it did the same thing! Apple needs to fix this!! It should be so easy!! I shouldn’t have to go buy a new alarm clock just to make sure I can make it to school and work on time!!!

just Like everyone else here this has happened to me a few times over the last few years and has caused me to be late for work, meetings, and even a flight once.


just yesterday it happened again - I have an iPhone 8 for context. I woke up an hour late to the “alarm going off” screen on my phone but no noise coming. I was in a hotel for work and supposed to meet my boss in the morning and head to a meeting. I missed the meeting and am now facing disciplinary action at work.


How has this happened to so many of us, and affected so many people so negatively yet nothing has been done?? People rely on their phone alarms, it’s one of the simplest yet most crucial features of an iPhone to so many people. I am a long term and avid iPhone user but we need reliability in our iPhones apple or I will be going somewhere else

Seriously... these phones are so expensive. I’ve never had this problem before and it’s incredibly annoying. My phone will play my alarm loudly for a second and then turn off. Literally a second 😐😐 and all the Apple responses don’t help... This phone is $700 and up and it can’t set a simple alarm when my iPhone 6 could? This is why didn’t want an “upgrade”. No one can tell me why this expensive phone can’t set an alarm like my iPhone 6 either 😐

I haven't read the complete thread but I've just registred to let you know that the exact same thing happened to me now as well.


I ran late for an important appointment because my $1000 iPhone X is not able to reliably activate an alarm. This has happened before, however I thought it was my bad -- it just didn't come to my mind that such an expensive phone could have such a ridiculous flaw.


Any support from Apple so far?

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.

I have Iphone 11...This has happened to me too, I thought I finally fixed the problem 2 days ago when I updated my phone then alarm worked the next day (I did also set 5 other alarms 1 minute apart to MAKE SURE it would work). I assumed the problem fixed itself. I set a later alarm for this morning because it wasn’t important to be up, just important to me. I was half awake and the alarm NEVER made a sound in the last 30 minutes that it was “going off”. I have tried all your “solutions” but nothing works as you say it will. I think Apple should be replacing phones at this point if you have so many people with the same issue not being properly solved.

Then perhaps you should talk to Apple. Apple doesn't read here for suggestions or reports of problems. Even Gus, who is an Apple employee, isn't charged with doing that. Contact Apple support using the Contact Support link at the top right of every page.


You can also submit feedback to Apple here:

Some of the people reading this thread have tried Gus's suggestions, some haven't. Some have figured out the cause of their problem, some haven't. What makes this difficult is that it's most likely more than one problem and it affects very few people. Those are the hardest to resolve.

IOS 13.4.1 my timer randomly works and then does not work. I use it for 20min reminders and not changing anything on the phone inbetween setting the reminders. Sometimes the timer works, other times it does not. I make a point of checking that I have actually set the timer and that it has begun counting down. When I get a sense of 'has 20mins not yet passed?', I pick up phone and what is showing is the starting display of the 20min duration. I'm manually setting my timer for 20mins two to three times/hour for 5hrs/day (20mins study periods). It happens several times per day, for no reason at all (meaning I've not touched/changed anything inbetween starting a new 20mins period). I've seen that this problem is ongoing over years...and Apple have not fixed it. WHY?

I am having the same issue. I have an alarm for 5:45, 6:00, and 7:00. The 7:00AM alarm works but the other 2 do not ring. I checked the alarm setting and all 3 are set to the same sound. I checked the volume setting and it was fine. Although we already know that. Otherwise, the 7:00AM alarm wouldn’t go off at full volume.

I’ve been using the iPhone alarm setting for over 5 years within problems. Thus needs to be fixed. I start a new job, need to wake up earlier, and can’t rely on iPhones alarm.

Please fix.
