iPhone alarm is silent randomly

Same problem, my iPad dont ring even though it does come on and looks like its ringing. If I test it by setting it to ring a couple of minites ahead, then it rings fine. But not when it is supposed to ring in the morning. Very frustrating, should be very simple to fix.

Didn't read it all through but someone said before that:

If You're setting multiple alarms, they mess up with each other if You snooze them.

I've noticed the same issue even if I don't snooze them.

I'm having problems waking up, therefore I set multiple alarms. One is definitely not enough. The excuse that my alarm didn't work is not trusted anymore. It's been too many times.

So, I've got few questions:

1.How long will the alarm sound until it stops. (I noticed that it is the specific amount of time)

2.In how many minutes is it going to ring again? (if it will)

3.How many times will it repeat this cycle?

4.What's gonna happen if one alarm is working, and there is another one comes up? Which one is gonna sound? If the first one will start ringing, then will the second start ringing after the first one is off?

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. More than half the time I sleep through my class and wake up with my alarms on my screen and having to turn off all of them, but they werent making any noise. 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

Hi Gus. It is not that the alarm is low or that there are headphones, bluetooth or wired connected. The ringer volume was almost at full, the do not disturb was not enabled. It just randomly happens that when the alarm goes off, the screen shows the alarm, but NO sound and no vibrate. My alarms are set to both ring and vibrate. Not even low sound. None.

Here I am, 2019, WAY after the original post to say that this STILL happens to me. It’s completely random. I can press snooze on my alarm, lie in bed awake, notice it’s not gone off in a while, check it and see that it appears (on the screen) to be going off, but there is no sound or vibration, press snooze again to see if it does it again, and then it works fine the next time it goes off. All my settings are fine. This is becoming a more frequent problem, and I am late getting my son to school sometimes because of it. I once missed a very important meeting. I have missed doctor appointments and more because of it. It’s not that I’m simply sleeping through it, though I’m sure that has happened before, because I was awake and talking to my husband when it did it again recently. Finally, there was my proof that I was not just sleeping through it. This is SO frustrating. I tried switching to Android recently. (Quite a traumatic experience, lol.) The one thing I really liked about it was the dependable alarm. Even if it went off until it shut itself off, it would go off again after about 10 minutes. It never did what this Apple alarm does, so I know it’s not me. I have triple checked the settings and followed the help instructions. It works properly about 85-90% of the time, but that is not acceptable. I need this to be dependable. (Also, I have no 3rd-party alarm apps on my phone.)

Exact same issue here. It’s happened around 4-5 times already. In the past I thought it was “pilot error” and that I had the ringer volume too low. Well that wasn’t the case today. After waking up late and seeing the screen showing the alarm was going off with no sound, I checked all settings and everything was as it should be...as it was the day before when the alarm did go off properly. I asked my son if he heard an alarm and he confirmed that he didn’t.

Apple needs to fix this and send an update pronto.

Yes. Yes, it sure did. What’s ridiculous is that this is still a problem. I wonder if Apple even knows how to fix it at this point. There’s no point in contacting them anymore. They give the same advice, assuming this is user error. I’m sure it is in some cases, but there are those of us who have checked everything, do the same thing every single day, and the problem is still random. That is not user error.

I am having this exact same issue Apple and it is TWO WHOLE YEARS LATER I know many people with android phones who all say they have never experienced this. I’m going to switch to Android because clearly Apple can’t make their devices reliable. When your customers rely on your devices to keep their jobs and make it to important things on time you better make sure your devices work properly. The more we rely on technology it seems the more it malfunctions it’s ridiculous.

So it's June 2019 and this issue hasn't been resolved? Is there a way to indicate the "Apple Recommended" response does not address anyone's issue? This happened to me today for the second time in three months - the first time, I missed a flight, today, I missed an important meeting. When I look at the phone, it visually looks like the alarm is going off (snooze and stop buttons displayed), but it's not making sound or vibrating at all.

Apple, please fix this issue! You can't have an alarm function that randomly completely fails. People really depend on their alarm.

i’m very frustrated. i work opening shifts at my coffee shop, so i always have to be up at extremely early hours. i’ve missed 2 days of work because of this issue. i woke up this morning to missed calls and texts but with no alarms showing they even went off!! i’m so frustrated and really don’t want to lose my job. i’m on a 7+ with the newest software updates. my boyfriend is having the same issue. any ideas??

My iPhone 10 did it again today for the second time and I was late for work. All settings are correct and updates are current.

We pay way to much money for this not to work like it should. I expect more from a company like Apple.

Its an alarm clock ! Fix it !!

Same thing happened to me. I confirmed that the ringer was turned all the way up, the alarm sound was NOT set to none, and there were no headphones connected to my phone, yet my alarm went off with no sound this morning. I have multiple alarms set every morning and all of them were silent for some reason.

Today again noticed bug with sound. Again alarm was going off without sound and only vibrating. Do not disturb was off, sound level on max and alarm song was Ripples and side switch was on ringer mode. I picked up phone and heard hissing noise on both speakers. Restarted phone and then problem disapeared. Later today bug returned and I missed one call because again phone only vibrating and no sound from speakers. Then I called back and nothing heard on ear speaker, It was silent. Again did restarted phone and problem gone.

Your problem sounds different than the subject of this thread. It sounds as if something is wrong with the speakers in your phone. I suggest you make arrangements with Apple to have it evaluated.

FWIW having the same issue on my XS on iOS 12.3.1.

Have tried all the suggestions on this thread but can’t get it to consistently work. About once every other week I wake up to the alarm screen but no sound.... fortunately haven’t overslept by more than 30 min so far, but seems like such a simple issue for a $1k phone to have?

What did Apple say when you talked to them?
