iOS 17 iPhone Alarm Turns Off with StandBy Mode

I set around 15 alarms to go off in the morning to wake me up. (I’m awful at making myself get up). So I give myself time to snooze. Ever since I’ve updated the newest one, anytime I snooze, the other Alarms aren’t going off or something? Idk but the past week I wake up to my 7 year old saying “momma, is today a school day?” Then I jump out of bed, get the kiddos ready & out the door but they’re already tardy! When the first alarm goes off, I usually just hold my phone in my hand so I can press the volume buttons to make it snooze. I’ve done this for literally YEARS. My kids are only allowed 5 tardies per school year and this past week has gotten us very close to that limit and we’re only 2 months in! I don’t have a wireless charger, just a regular type C. I did have standby mode set to on since the update bc I use the sleep focus at night to quiet notifications. But after the first 2 mornings of not waking, I stopped using the Sleep focus. I’m legit terrified to even go to sleep bc I can’t trust my alarms to actually do their job! So now I have to download an alarm app as a backup…which defeats the purpose of the built in alarm option😩

It has been true for years that, if you snooze an alarm and the snooze overlaps with a subsequent alarm, the subsequent alarm will not fire. So, either set your alarms to be more than nine minutes apart (and only snooze once) or diable this snooze function and just rely on the multiple alarms.

Hi, so installed 17.1 and tested. Alarms are triggered ok, but silent alarms wont vibrate they just notice you on the screen, tested with sounds and worked. I think that vibrate while in magnetic charger is disabled to avoid the phone to unlock?

I have noticed that when in standby mode and my phone is in DND sleep, I can tap snooze ONE time. However, when those 9 minutes are up my alarm turns off completely. I noticed this because I listen to music through headphones while I sleep (gotta drown out the partner's snoring lol) and the music will temporarily pause like the alarm is going to go off but then the music will resume 1 second later. I look at my phone and it is still in standby mode with DND sleep on and the alarm is turned off completely.

I did not touch the phone after the first snooze, I did not look at the phone after the first snooze, I did not even bump the table it was on.

This is only happening in standby mode, which is super frustrating because I wake up through the night and like to quickly look at the time without getting blinded by the light on my phone. So standby mode has been perfect for me. This issue does not happen when I have the phone in portrait mode with the DND sleep on. Please fix this issue apple.

Currently on iOS 17.0.3 with an iPhone 15

The worst part is the stop is located where snooze previously was on the screen. Stop was at the bottom not the middle. It took me 3 days of over sleeping before I realized what the problem was. Thanks for helping me almost lose my job Apple!

I’m having the same issue. My iPhone XS is on charge and placed in a phone stand overnight. Last night I set my alarm and ringtone so high that everyone on my floor and the floor below me should be able to hear it. I have multiple alarms and my phone only did one of my earlier alarm which was extremely quiet and it played none of my other alarms. This morning I woke up an hour late and I clicked on the screen to see one alarm that has snoozed by itself. I’ve missed so many days I don’t know what to do!!!!!! How do we get apple to fix their mistake!

I did a quick test where I set an alarm and left it (without standby mode) and it worked perfectly fine. Then, I put an alarm on and set my phone on standby mode. My screen showed that my alarm is playing but there was no sound at all! How do we get Apple to fix this?

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!!

You’re not alone, I nearly lost my job because of this bug. Ever since iOS 17, never had an issue before. Happens on my iPhone 15 Pro Max and my spouses iPhone 13 Pro Max both on iOS 17.2.1 (started on iOS 17.0). Turned off StandBy, Face ID Awareness/Attention, DND, Sleep Focus, Volume Up, etc., but nothing works! If I set a test alarm or manually change the time on iPhone it works as it should, but the moment I set it “for real” I find out it’s 5am and my 3am alarm never went off yet when I tested my alarm before going to bed it was so loud it would wake the entire house up.

This is BEYOND infuriating for how much these phones cost that can’t even function as a simple alarm. What a joke.

This worked for me! I can now use StandBy correctly. Though it is insane that glancing at my phone to find the Snooze button before falling back asleep was apparently also telling my phone that I'm awake and aware enough to turn off my alarm ringer.

This needs fixed in Standby. A button press should have the affect of snooze just like it does when the phone is just plugged up to charge. The only thing that should stop an alarm is hitting the stop button. In standby the stop button should also be smaller. Please fix this, Apple!!

latest update did not fix… happened to me this morning (tested it out again since I didn’t have to get up at a certain time). If I lay my phone flat (face up) my alarm always works. If I lay it sideways (in standby). It never works!!! It’s 100% failure rate. Smh 🤦🏼‍♂️

congrats Apple on making my alarm didn’t work/go off . Excuse valid in 2024. 🫠

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 felt like I've been missing a ton of alarms recently, and this makes so much sense. When my alarm goes off I often grab the phone and hit a button to snooze it. I guess from Standby this turns off the alarm? The alarm should need very clear user input to turn off.

The alarm issue also impacts me on my iPhone 12 mini. Also found that standby mode breaks my custom setting for do not disturb and the notification summary feature—ignores it like I never set it up. Until this is fixed, standby mode is a worthless feature.

This issue still persists and sadly this is my first experience with an IPhone. I’ve been late more times to my job in the past 3 months than I ever have been in the last 14 years. I’ve only ever had androids and switching to iPhone has been great but I’m not gonna let this phone take my job. I will be switching back if this issue isn’t resolved soon.
