The most common reasons alarms are not going off, especially on iPhones, include features that automatically lower or mute the alarm sound such as "Attention Aware Features," low or muted volume settings, enabled Do Not Disturb or Sleep Focus modes, incorrect alarm settings, or software glitches. If your phone is connected to external devices like Bluetooth headphones, the alarm sound may play through those instead of the phone speaker, making it seem like the alarm didn't go off. To fix this:
- Disable "Attention Aware Features" in Settings > Face ID & Attention.
- Increase the volume for Ringer and Alerts under Settings > Sounds & Haptics.
- Make sure the mute switch is off.
- Turn off Do Not Disturb or Sleep Focus modes from the Control Center.
- Check the alarm time and sound settings in the Clock app.
- Disconnect any external audio devices like Bluetooth headphones.
- Restart your phone and ensure the software is updated to the latest version.
If these steps don't resolve the issue, a system reset or hardware check may be required. Having a backup alarm like a traditional alarm clock is also advised in case of emergencies.
