iPhone alarm sound not playing on iOS 26

Do you feel extreme heat when sleep mode is on and when we allow alarm notifications in sleep mode? At that time, the phone heats up too much?

This has been driving me insane! I’ve been late to work so much the last few weeks. Why did this need to change? There was no issue with how it worked before.

I’ve also discovered this. Great that you report it! I will too.

For me, it started happening after updating to 26.2 😕

Similar here. I use the sleep schedule alarm and the side buttons to snooze (usually the on/off but they used to be the same) I do get the initial alarm, but not the snooze. Now the button appears to mute the alarm but the image on the screen appears to look like the alarm is still going. No additional snooze alarms ever sound. I have to open the clock app for it to register that I am awake.

I experienced this issue tonight. I asked Siri what happened to the alarm and it replied that it had turned them off. I’m not sure why this has happened. I think this was the first system upgrade I’ve done. I guess I’ll have to troubleshoot to see if it works.

This just happened to me on my Air on OS26. I woke up late this morning to the alarm going off on my phone but no sound playing.

This is super frustrating as in Silent Mode it says alarms will play, and it did flawlessly in OS18 with no issues.

Glad I found this this morning. This has happened to me ever since I updated my phone. I’m a button snoozer so literally every morning I’ll press the side button to snooze out of force of habit. I’ve woken up an hour late three times now and the alarm screen is just sitting open with the option to snooze. I really hope Apple brings back the snooze toggle with side buttons.

Seeing this issue as well. Never had a problem with the alarm until iOS 26. Woke up late on my own to my phone showing the options to snooze or stop the alarm. I have an iPhone 14 Pro and Watch Ultra 3. The watch was also showing the same snooze or stop options but completely silent and no haptic taps either. I don’t know what I did to completely silence the alarm instead of snoozing it. This should be reverted to the previous behavior which didn’t lead to this state of a muted active alarm which is pretty useless.

Same. Ever since I upgraded (a day after 26.0 came out), my morning alarm mostly doesn’t work. Sometimes it has the sound, a loud one, sometimes it doesn’t at all. There is nothing I noticed that could help unfortunately. Never was late to work and now I am regularly late. Wish I could revert back to 18.7 but they removed this backup to this version. That is terrible.

This was happening to me too. I had to go in settings, sounds and haptics, and turn the sound up. The update turns the sound completely down. Now it works like it used to. My phone is still on silent no sounds for texts and calls but my alarm now makes sound.

Same here, updated last thursday and alarms are hit or miss. Sometimes they sound, sometimes they don't. I rely on alarms and use an automation to schedule them to sound before all my meetings so I don't work through them and now I can't trust or rely on my alarms. It's so annoying!!

Happening to me too, but can't confirm if it's just alarm sound, or any other sound. I realised this was buggy due to my lock sound disappear even switching it off/on in settings.

Disabling Attention Aware Features and reenabling it back brings my lock screen sound back.

It seems to be limited to while you’re looking at the phone. It’s either extremely low or doesn’t play at all. I also turned it back on to verify, and I continued to look at the phone, even if I wasn’t on a particular screen as long as the screen itself wasn’t locked the alarm doesn’t play

It’s a bug that definitely Apple needs to look at or disassociate the alarms entirely from the setting

Same issue here. My alarm has intermittently failed to make a sound over the past couple of days. This only started occurring after updating to iOS 26.

iPhone 13 Pro
