iPhone alarms are usually silent and do not vibrate.

This has been an issue I’ve had off and on for several years with iPhones, but lately it seems like it’s gotten worse. More often than not, my alarms make zero noise. I had to go buy an alarm clock months ago because I couldn’t trust my iPhone’s alarm. It’s gotten even more unreliable since then. That’s not good. I’ve noticed the alarm I have to end my sleep focus at 5:00 never makes any noise and doesn’t vibrate. Other alarms are hit and miss. This evening, for instance, an alarm I had to remind me to do something didn’t ring and didn’t vibrate. I checked and it isn’t set to “none” for the sound. Neither is my sleep alarm. I just don’t know what to do to fix this.

I'm sorry to hear that you're experiencing issues with your iPhone 12 Pro Max alarms. There could be several reasons why your alarms are not sounding or vibrating. Here are some troubleshooting steps you can try:


  1. Make sure that the volume is turned up and not on silent or vibrate mode. You can check this by using the volume buttons on the side of your iPhone or by going to Settings > Sounds & Haptics and adjusting the volume slider.
  2. Verify that you have selected a sound for your alarms. You can do this by going to the Clock app, selecting the Alarm tab, and tapping "Edit" in the top left corner of the screen. Then, tap on the alarm you want to check and make sure you have chosen a sound.
    1. Probably you have set the Alarm Sound to NONE. Watch the GIF below
  3. Check for Do Not Disturb or Bedtime Mode: If you have Do Not Disturb or Bedtime Mode enabled, your alarms might be silenced. Check the Control Center or Settings to ensure these features are disabled.
  4. Sometimes, a simple restart can resolve temporary software glitches. Turn off your iPhone, wait for a few seconds, and then turn it back on.
    1. Restart the device. That's it.
    2. Still not solved --> Force restart iPhone - Apple Support
  5. If the issue persists, you can try resetting all settings on your iPhone. This will not erase your data but will reset all personalized settings to their default values. Go to Settings > General > Transfer & Reset > Reset > Reset All Settings and confirm the action. Note that you will need to reconfigure your settings afterward. All settings—including network settings, the keyboard dictionary, the Home screen layout, location settings, privacy settings, and Apple Pay cards—are removed or reset to their defaults. No data or media are deleted.
    1. Reset All Settings: Return iPhone settings to their defaults - Apple Support:- Return iPhone settings to their defaults
    2. You can return settings to their defaults without erasing your content.
    3. If you want to save your settings, back up your iPhone before returning them to their defaults. For example, if you’re trying to solve a problem but returning settings to their defaults doesn’t help, you might want to restore your previous settings from a backup.
  6. Make sure you have the latest updates installed.
    1. Update Over-the-Air (OTA) —> Update your iPhone or iPad - Apple Support (IN)
    2. Update using iTunes/Finder —> Update your iPhone, iPad, or iPod touch - Apple Support (IN)


If none of the above steps resolve the issue, it is recommended to reach out to Apple Support or visit an authorized service center for further assistance. They can provide specific guidance based on your device model and iOS version.

Which means that if you accidentally happens to need 3-4 alarms one morning because of night duties in the home you need to set several alarms with 5-10 minutes in between?

I done this, but the alarm is silenced by any movement, new alarm or SMS coming in at the same time.

On top, if alarm starts off loud, it goes very silent or totally silent within 1 second.

For $2,0000+ that's not something I think would be a feature in a very expensive (for ordinary people very expensive). I believe Apple has a work around, but chose silent alarms as a built-in feature?

One of these suggestions helped I think. But still feels like a design problem more than user error. If I set an alarm, I want to be notified. Period. Unless I set the alarm sound to None, it should go off. I should not have to check my ringer volume, do not disturb setting, or sleep focus as well. It’s also hard to understand how all these features interact generally. Please work on this Apple. Sincerely, a UX Researcher.

I have missed exams and other important meetings because of this problem. How is the official Apple response: "Go and change 20 hidden settings, where you have to turn on all your sounds." I don’t want to have notification sounds or others on, but i want my alarm to make an ALARM. How is there not just an option to keep your sound off, but the alarm at full blast. For one of the largest companies on earth to not be able to create a functioning and simple alarm is ridiculous. I just had enough and bought a classic alarm clock with bells for 10€. How is a >1000€ phone unable to do this?

And yet, most of us manage to use the alarm on our iPhones with no problems. I haven't owned any other sort of alarm for more than a decade. My employers could attest to my lack of tardiness (despite not being a morning person). The difference between you and me is, perhaps, that I don't view learning how my complex tech works as something I shouldn't have to do.

This is ridiculous. First, this has been happening since I get my iPhone 14 1.5 years ago. Two, sometimes it works and other times it does not. I have not changed any settings, but my iPhone decides when it wants to function properly. This is not only a basic issue that should always work, it is extremely important. I travel for work including internationally and I cannot rely on my phone to perform as it is supposed to.

This is an obvious software error from Appl. I've delt with it on every iPhone I've owned for the last few years. It happened again this morning and it's ironic it usually happens when I ignore an update for too many days. I wouldn't be surprised if Apple does this initially so you panic trying to figure out the problem and you instinctively update. I'm just speculating but it almost ALWAYS happens when an update is dismissed for too many days.

I’ve had serious problems with this current phone and past I phones where the alarm will not go off. I’m in the army and it’s detrimental that I make my hit times so I kind of have to rely on my phones alarm, but as of recent, my phone for some reason just won’t go off. **** I even missed calls from people trying to wake me up. This is a serious problem that needs to be addressed.

So i set 4 alarms from 5:30am to 6am for this morning… DnD automatically comes off schedule at 5am. I made sure after having this issue only 2 days prior for my phone to be on loud, volume up fully & on charge… tell me why this morning when i’ve gone on my phone it was on 100% but showed the apple logo as if it’d been turned off during the night 🤷🏾‍♂️ no alarms gone off n phone as if it’d been switched off??? 2 days of work i’ve missed due to this issue!!!!????
