When Do Not Disturb mode is enabled, it prevents sounds and alerts from going off. This is regardless of how high your ringer volume is. An exception to this rule is the person calling or messaging you is in your favorite contact lists.

If you have this mode enabled, you can turn it on or off in two ways:

Step 1: On the Lock screen, swipe up from the bottom of the screen to open the Control Centre, then tap Do Not Disturb.

If your iPhone is connected to a Bluetooth speaker or WiFi network while an alarm is active, it may not play any sound because it will not use its regular speakers.

And therefore, you may fail to hear the alarm ringing, which is particularly true if you have connected your iPhone to Bluetooth headphones. The alarm will ring through the headphones, and chances are high you don't sleep with your headphones on.

Your alarm may also fail if you reside with people whose Bluetooth speakers automatically connect to your iPhone. You can prevent this issue by putting your iPhone in Airplane Mode prior to going to bed.

10. Remove Third-Party Alarm Clock Apps

Your iPhone's alarm may not go off when you have third-party alarm apps running in the background. It is recommendable that you either use the default iPhone alarm clock or disable the default app if you have to use third-party apps.

But before you disable the default alarm app, disable or remove the third-party apps first.

11. Restore Your iPhone Factory Settings

Restoring your device's factory setting should be the last resort to fixing an iPhone's alarm that does not go off. Restoring factory settings will wipe out all settings and saved data on your iPhone and revert it to the factory settings. Thus, before undertaking this step, ensure you create a backup of the data you don't want to lose.

Since factory resetting resets everything that is software-related, it will solve the alarm malfunctioning issue.

To factory reset your iPhone;

Step 1: Open the Settings app and go to General > Reset (If you are using iOS 15, you'll have the option of Transfer or Reset iPhone).
