iPhone 15 alarm not working

i have two phones - a 14 for work and a 15 for personal. My morning alarm does not work on my 15, so I’ve now had to resort to using my 14 for my morning alarm. Time is set correctly, volume is turned ALL the way up and it still won’t go off. Apps are update. It’s got to be a bug in the new 15 operating system.

iPhone 15 Pro, iOS 17

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!!

After purchasing a very expensive phone we should not have to become an IT professional overnight to turn off settings/turn setings back on/download free alarms that have so many pop up adds you cant set the alarm/ or purchase from the Apple store another alarm simply because of an Apple malfunction. Absurd and very frustrating as they could have or should have had a fix by now!!

I am having the exact same issue. I'm staring at the alarm going off and no sound. All volumes are up both on ringer and in Sounds and Haptics, I've already hard reset my phone 5 times. When I hold it up to my ear, I hear the faintest ring of the alarm but it doesn't last the entire time the ring is going off. I deleted the Clock app and reinstalled. When I tried to set a new alarm, it said "Sleep is now managed through the Health app" and then forced me to go in there and wanted to me to set up a sleep schedule. I don't need any of this fancy stuff. Just give me my d**n alarm! Any suggestions for a good SIMPLE alarm app?

I am so sick of this. This phone is going to get me fired. I make sure the ringer volume is max. Silence mode off. The alarm has the most obnoxious noise possible. I set like 8 of them over the span of an hour, and still no alarm! It just shows the alarm screen but makes no noise. This is going to get me fired from my job and I’ve already missed a few morning college classes. I’m just about through with my phone I need to have my alarms. I’ve just now tried removing the standby screen as per request of another user in this thread.

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.

I have the same issue with my iPhone 13 Pro ever since the iOS updated. At first I thought it was me and then I started testing different things. I have followed every single troubleshooting option. I have deleted and created new alarms. I have resorted it to Setting my Amazon Alexa app every day. This is absolutely ridiculous. Many of us used alarm clocks back in the day and now we rely on our cell phones because they are portable. Why should we have to download a third-party app? It makes me question Apple if they can’t fix something as simple as the alarm clock.
