The common reasons why an iPhone alarm may not be going off include:
- Attention Aware Features turning down the alarm volume if you are looking at the phone (iPhone X and later).
- Volume settings being too low or the mute switch on the side being on.
- Do Not Disturb or Sleep Focus modes silencing the alarm.
- Incorrect alarm settings such as wrong time or no sound selected.
- A software glitch or outdated iOS version.
- Connection to external devices like Bluetooth headphones, causing the alarm sound to play elsewhere.
To fix the problem, try these steps:
- Turn off Attention Aware Features in Settings > Face ID & Attention.
- Check and increase volume in Settings > Sounds & Haptics.
- Ensure the mute switch is off.
- Turn off Do Not Disturb or Sleep Focus modes.
- Verify alarm time and sound in the Clock app.
- Restart your iPhone.
- Update to the latest iOS.
- Disconnect from any external audio devices.
- Reset all settings if needed, via Settings > General > Transfer or Reset iPhone > Reset All Settings.
If the issue persists, it may be a hardware problem and visiting an Apple repair store is advised.
