iPhone 15 alarm not working

After I updated to iOS 17 my alarm stopped making noise too. I fixed it by disabling the standby feature. It installed default On. I noticed that when I picked up my phone in the morning (after using a normal alarm clock because I stopped replying on my iPhone) this odd screen showed up including a little red bell.

Try turning this off and report back!!

I have been in contact 5 times with Apple support over the last 2 months about the alarm app.

They told me the last two times: "they know there is a problem and the software people are working on it."

They said to keep my phone up-to-date and for me to download a free alarm app and use it until they can fix the app.

Yup, new phone, no alarm.

The following steps resolved this for me: I have an iPhone 15 with 17.1.1 installed. Go into settings, Sounds and Haptics. Slide the “ringtones and alerts” volume bar up. This volume setting is separate from the side volume buttons, apparently. Test out your alarms, it should work normally.

Most fixes work, but only for about 1-2 weeks. If it similar to my phone after that it starts to miss an alarm now and then or just sound one or two notes then turn off then slowly stops working again.

I've reset everything more than once, used Apple customer service and did all their steps. Did everything that worked for people here. It only works for a week or so.

Apple says it is a glitch in the software with the new clock/alarm, they are aware and are working on it. They suggest to use another app for an alarm until they fix it.

I've contacted Apple about this issue on my new phone (bought in Sept).

Hope I’m not too late but if you toggle off “attention aware” and “attention aware features” (which I know, it sucks to turn off) in settings, then the alarm in nightstand mode will work.. just do a settings search the two mentioned above and you will find those settings. still not the best but at least I can hear the alarm at least once.. I believe the problem is with the always on feature of the nightstand clock.. it thinks you are somehow looking at the screen..

For the past two weeks my alarm has not been working. What I have found is none of the alarm tones work but if I use a song from my playlist then the alarm will go off with song playing. I have switched all the alarm tones to a song from my playlist and I’m no longer late for work!

Same issue here. I believe I found the issue. When the alarm goes off and I turn my face in the direction of my phone, it automatically goes into that silent mode and stays there. The screen still shows the alarm is going off but no sound. My theory is when I roll over in bed, not even close to being awake, the phone recognizes my face and puts it in this mode, which obviously causes significant issues bc I’m not awake enough to even register that the alarm is going off.

Last night I put the phone on the charger on my night stand and then turned the phone away from my direction so it couldn’t pick up my face - and that worked. The alarm went off normal.

Just playing with the phone and the alarm, if I set an alarm and it goes off, it continues to go off until I hit the button. However, when the alarm starts going off and I put my face in view of the front of the phone, the alarm goes into that silent mode without me touching anything.

Try turning your phone away from you at night so it can’t perform the face recognition or turn that feature off.

Yes it is very frustrating.

This is an on-going software problem Apple has yet to fix. They are very aware of the problem and are working on it.

I bought mine in September and called for help 5 times. We verified the problem even rebooted my phone twice.

Their advice was to find an alarm app and download it until the problem is fixed.

Note: there are lots of fixes shown here and many will work...for a while. The software problem is insidious and will come back in a week or so. If it is like mine it will start by missing occasionally or only play one "note" for a week or so before stopping completely. Very random.

I went to settings and typed "sound" in the search bar. Scroll down to Sound Recognition, click on it. Then click "back" in the upper left hand corner. Scroll down to Face ID & Attention. click. Then disable "Require Attention for Face ID" and "Attention Aware Features". It may work if only "Attention Aware Features" is disabled. I have tried it yet, but since I don't use Face ID, I just disabled them both. I have tried it several times and the alarm seems to stay on with volume...

While Silent Mode didnt disable alarms in the past - that is not true on iPhone 15 and the ios update. Now having the phone in silent mode for ringing does silence your alarm. I see above people had to turn off their sleep schedule to get them back, which is a bummer as I like that feature.

After I updated to iOS 17 my alarm stopped making noise too, but only for my first alarm of the day at 5:30am. It would work just fine for all of my other scheduled alarms throughout the day. I tried for months to fix it using recommendations from various online sources, with no success.

I finally fixed it by doing a factory reset. No issues with my alarm working ever since (just a pain to have to personalize all my settings over again)!

I believe I finally found the correct solution on a Reddit thread. After fixing this my alarm has worked correctly for the last week. Go into settings and disable standby mode. I’ve had this issue for months and debated switching to Android. I don’t understand why Apple didn’t roll out a quick solution for something so many of us use.

At Carissa’s suggestion above I went into settings and turn off sleep schedule/mode and I got my alarms back. Maybe you could try this.

I contacted Apple, they told me to delete the clock and re install it, now my alarms work again :)

If the alarm volume is too low or quiet

Do Not Disturb and the Ring/Silent switch don’t affect the alarm sound. If you set your Ring/Silent switch to Silent or turn on Do Not Disturb, the alarm will still sound.

If your alarm doesn’t sound or is too quiet, or if your iPhone only vibrates, check the following:

• Set the volume on your iPhone. If your alarm volume is too low or too loud, press the volume up or volume down button to adjust it. You can also go to Settings > Sounds & Haptics and drag the slider under Ringtone and Alert Volume.
• If your alarm only vibrates, make sure your alarm sound isn’t set to None. Open the Clock app, tap the Alarm tab, then tap Edit. Tap the alarm, then tap Sound and choose a Sound.
• If you connect headphones to your iPhone, the alarm will play at a set volume through the built-in speakers on your iPhone as well as wired and wireless headphones.

Manually adjusting the time on your iPhone in Settings to change app behaviour, such as game timers, isn’t recommended and can affect alarms.
