1B: Edit the Alarm Settings

It’s easy to make mistakes such as using the wrong time format (12-hour vs. 24-hour) or mixing up AM and PM. Or you might have set a one-time alarm instead of a recurring one. 

1. Open the Clock app and tap on the Alarm tab located at the bottom of the screen.

2. Check the alarm time and format. Confirm that it is turned ON.

3. If you need to make any adjustments, tap on the Edit button and select the specific alarm that you need to edit.

4. Tap on Save to save the changes.

If ringtone is the issue, choose a louder alarm tone to ensure you can hear it clearly. Also, make sure the alarm tone is not set to None to avoid silent alarms. 

1. In the Alarm tab, tap on Edit.

2. Select the alarm for which you want to reconfigure the sound.

3. Tap on Sound and choose a tone from the available options.

A simple solution in many cases is to delete the existing alarms and set up new ones. 

1. Open the Clock app and swipe left on the alarm you want to delete. Tap on Delete.

2. To create a new alarm, tap on the Plus + button located in the upper-right corner.

3. Select the desired time for the alarm and once all the settings have been configured, tap on Save.

Method 4: Disable or Change the Bedtime Feature

Sometimes, enabling the Bedtime feature can interfere with the proper functioning of alarms, especially when there is a conflict in timing. Make sure to review and modify the Sleep mode settings accordingly to ensure your alarms work correctly.

1. Open the Health app on your iPhone and tap on Sleep.

Note: If your device is running on an OS version older than iOS 15, go to Clock and then Bedtime.

2. Select Full Schedule & Options and then tap on Edit.

3. To adjust your wake-up time, move the wake-up icon to the desired time.

4. If you prefer to delete the sleep schedule entirely, scroll down and tap on Delete Schedule.

5. Finally, tap Done to save the changes.

Method 5: Use Only One Alarm Clock App

If you have installed a third-party alarm app, then do note that using multiple alarm apps simultaneously can cause complications. It is recommended to uninstall it and rely on the default alarm app for a smoother experience.

Method 6: Disable Bluetooth and Unplug Headphones

In most cases, the alarm should ring through the device speakers regardless of any connected headphones or Bluetooth devices. However, by virtue of a glitch or software bug, it may play the alarm tone through the connected devices instead. To prevent this, it is recommended to disconnect Bluetooth or unplug any connected audio devices.

1. Swipe down from the top right corner of your screen to open the Control Centre.

2. Tap on the Bluetooth icon to toggle it off.

Method 7: Set Alarm Through the Clock App

Many iPhone users have reported that the alarm does not go off when they set it using their Apple Watch. If you also set the alarm through the watch,  try to set and configure it directly through the Clock app on your iPhone. See if it resolves the issue.

Method 8: Update iOS

The issue could also be due to an outdated iOS version. Software updates often include new features, security enhancements, and bug fixes that might resolve the error.

1. Open Settings and tap on General.

2. Scroll down and tap on Software Update.

4. If an update is available, you will see the option to Download and Install. Tap on it.

2. Scroll down and tap on Transfer or Reset iPhone.

Method 10: Restore iPhone to Factory Default Settings

Factory resetting your iPhone is an extreme measure that can potentially resolve persistent alarm issues. It removes glitches or software bugs that may be causing the problem.

Note: A factory reset erases all data and settings on your iPhone. So, ensure to have a backup of all your data.

1. In the General settings, scroll down and tap on Transfer or Reset iPhone.

2. Select Erase All Content and Settings.

You will be prompted to enter your passcode. Enter it when asked.
