Some iPhone owners are reporting that their alarms aren’t working.
The issue seems to affect a variety of old and new iPhones running iOS 17 to iOS 17.2.
Pretty much all smartphones have built-in alarm clocks, and millions of people rely on this feature to get their day started. Unfortunately, it sounds like plenty of iPhone owners are reporting broken alarm functionality.
Loads of Redditors on the iPhone subreddit have reported issues with the alarm on their iPhones. These users report that the alarms are either failing to go off at all or that the phone screen lights up but there’s no sound.
The issue doesn’t seem to be restricted to specific iPhones, as people with older handsets also seem to be suffering from the problem. In fact, even iPhone XR and iPhone 11 series owners reported that their alarms weren’t working. It also doesn’t seem to be limited to the brand-new iOS 17.2 update, as some iPhone owners in the thread have claimed this issue occurs on iOS 17 too.
How to fix your iPhone alarm not going off in iOS 17
To solve the issue, run through the troubleshooting steps below, which should typically diagnose the situation and provide an obvious fix.
1. Adjust your volume levels
We use the plural here because you should check both your main volume and the volume for ringtones and alerts. For the former, just use the volume buttons on your iPhone. For the latter, go to Settings > Sounds and Hapticsand experiment with the Ringtones and Alerts volume slider. We’d also recommend setting Haptics to Always Play, since the combination of an alarm tone and vibration motor is almost impossible to ignore.
2. Doublecheck that the proper alarm is active
As a rule, we recommend using the integrated alarm option linked to your Sleep Schedule. You should avoid creating a duplicate alarm in the Clock app, in fact, because that can trigger conflicts. Go to the Alarms tab in the Clock app and make sure that either Sleep/Wake-Up or a custom alarm is active, but not both. If you’re using a custom alarm, tap on it to see if it’s set to repeat on the days you need it. You can create unique weekday and weekend alarms, for instance.
If a paired Bluetooth audio accessory is on, sound will usually be routed through that instead of your iPhone’s internal speakers. You can see what’s currently connected to your iPhone by going to Settings > Bluetooth. If an accessory needs to stay on for some reason, you can temporarily disconnect it from your iPhone by tapping the i (info)button next to it, then Disconnect. You’ll have to manually reconnect later.
4. Delete and recreate any custom alarms
If a custom alarm is failing to go off even after trying all of the steps above, you may need to simply recreate it. This sometimes works for whatever reason. In the Clock app’s Alarms tab, swipe left on an alarm to reveal the Delete button. Once the alarm is removed, hit the plus icon up top to make a new one.
5. Restart your iPhone
If alarm is not working because of a minor iOS 17 bug, restarting your iPhone may be enough to fix the problem. To restart an iPhone without a home button (which is most models, these days), hold down the side button and one of the volume buttons until a set of sliders appears onscreen. Drag the Slide to power off slider all the way to the right. After your iPhone goes completely black, hold the side button to power back on.
6. Check for iOS updates
If restarting your iPhone didn’t resolve your issue, we can assume there’s a major bug in the iOS 17 software. Apple may have already released an update to solve alarm-related bug. To find out if an iOS update is available, go to Settings–>General–>Software Update. If an update is available, tap Update Now.
7. Reset all settings
If your iPhone alarm isn’t going off even after trying all the tips mentioned, we should try a slightly more drastic measure. You can factory reset only your settings, without having to wipe the phone. Resetting all settings on an iPhone is a way to revert various system and configuration settings back to their factory default values, including network settings like Wi-Fi passwords, privacy settings, display settings and more. This does not affect your personal data, such as photos, videos, contacts, or apps.
Tap Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings and then follow the onscreen instructions.
