iOS 17 iPhone Alarm Turns Off with StandBy Mode

When StandBy Mode is turned on and active while the phone is in the landscape position, if the alarm goes off and the phone is disturbed (taken off the charger/ slightly bumped off the charger, or taken out of StandBy Mode the alarm will actually completely turn off.


The reason I hope this is just a setting I can disable without disabling STandBy mode is I like to check the time throughout the night, however, when i wake up in the morning I'd rather press a physical button as I've accidentally pressed the wrong one. But now every time I barely touch my phone it will stop the alarm and not snooze it.

Yep, second time in a week that I overslept by an hour because my alarm was mysteriously off while in StandBy mode. Been using the Sleep alarm for years without any issue, StandBy is the only new variable, frustrating bc I just bought a stand just to use with StandBy!

💡 Solution: In order for morning alarms to ring while your iPhone is in StandBy Mode, make sure to set a “Sleep | Wake Up” alarm in the Clock or Health App for the time you want instead of setting a normal alarm. This worked well for me. The alarm plays loud and clear and the UI in StandBy includes a large snooze button, stop button, and even a nice good morning message. Hope that helps! :)

Has anyone from Apple commented on the snooze issue on iOS 17 - updated to iOS 17.2.1 and issue is still there.

  • Turns off if phone picked up
  • Sometimes turns off after one ring (and not touched)
  • Sometimes turns off all subsequent alarms.
  • Sometimes works (if alarm screen is open).


started new job a week ago and have to use an old-school alarm clock as I don’t trust it at all - travelling soon and very worried about over sleeping with jet lag.

Apple -please fix the basics please

This is why I went back to using my 1980s clock radio to wake me up! I just updated to iOS 17; never had nightstand mode before. First off, the blood red display was creepy to me. Second, Apple: STOP making us late for work and school! Not everyone can get out of bed as soon as the alarm is heard! I also use my alarm as a 2-in-1…it wakes me up, I hit snooze a couple times, then once I’m up it reminds me to take my morning medication! When I touch the phone in nightstand mode and it clears all my alarms, well, not very helpful!!

My alarms have been flawless for months. Standby mode is OFF. As far as I am concerned standby mode is useless whilst this issue persists.


I keep coming back here to see if there's any evidence it has been resolved so that I may again try out standby mode one day.


I don't understand why it isn't fixed do you think nobody is paying attention, has anyone raised it directly to apple support.

I also thought I was crazy, am so glad to find this forum with hundreds of people saying this is a problem for them too, as there's some hope that Apple will fix it. Still a problem for me with iPhone 15 Pro and 17.3.1, I'd say 90% of the time my alarms work, 10% of the time, I wake up well after the alarm, the screen is on, the alarm is "going" but no sound (like it has been silenced or something). The phone is far enough from the bed on the nightstand that I'm not accidentally touching it and it's not being moved, but maybe it detects motion or something and turns off, or maybe if it has recently detected motion before the alarm goes off, it doesn't go off. Whatever is going on, it's super bad, and I guess I'll give up on using Standby until folks report that it's been fixed :(

I ran some tests on this issue because I was having it too. I found that background apps, air pods, music didn’t affect the alarms in standby mode.. but notifications definitely did. If I have a text on the screen in standby mode then the alarm won’t sound. That’s the only way I’ve been able to replicate a failed alarm so far.

I just bought a charging stand that allows for landscape mode for my iphone with the intention to use landscape mode since its a feature they offer. Little did I know, I've been sleeping in lately and missing meetings/events and I couldn't tell why. I realized today that my typical morning routine is to physically press the volume buttons to snooze the alarm once so I can gracefully wake up. This bug is still persistent as of 17.4.1 which my iphone version is currently on. I've had to disable standby mode completely in the meantime. It doesn't seem helpful that a snooze/cancel alarm screen pops up only while the iphone is on the charging stand as I'm attempting to gain eyesight while im waking up and need to pickup my iphone and press physical buttons instead. It certainly doesn't help that the alarm automatically shuts off and snooze is disabled once picked up off the charging stand

You should definitely pass that information on to Apple:
