11 Tips to Fix iPhone Alarm Not Going Off in iOS 17

User Concern

“I have an iPhone 14. Why does my alarm not go off? It's not just my alarm; it's my whole clock app; it doesn't work as in the alarm doesn't ring, and the timer doesn't go off.”

Many users depend on their phones to wake up on time. But what if your iPhone alarm isn't going off? You might wake up later and miss important events. If your iPhone alarm isn't working, you've come to the right place. This guide will help you solve the problem and get your iPhone alarm working again.

Why Is My Alarm Not Going Off on My iPhone?

If you have set an alarm on your iPhone but it never goes off, you're not alone, and you can try to solve it as follows:

• iPhone alarm will not work after the phone is turned off. So remember to keep your iPhone open after setting the alarm.
• You may have set the alarm, but forget to turn it on before going to sleep, which ultimately causes the alarm not working in the next morning.
• Ensure the iPhone is fully charged after setting the alarm, or the alarm clock will automatically shut down due to the low battery power.

If none of these problems are found, other errors may exist on your iPhone. You can follow the 11 tips below to fix the iPhone alarm not going off problem.

Tip 1. Adjust Volume Level

You might think you can increase the alarm volume with the side buttons on your iPhone, but that's not the case. The side buttons control two different volumes: ringer volume and media volume.

By default, the ringer volume controls the system sounds, like ringer, notifications, alarms, etc., while the media volume affects the sound of media apps like music, games, videos, etc.

If you have a music app open, the side buttons will change the music volume, not the alarm volume. If your alarm volume is down or off, the alarm will be silent.

1. You can head over to Settings on your iPhone and click on Sounds or Sounds & Haptics.
2. Ensure the RINGER AND ALERTS slider is set to a reasonable volume and turn off the option of Change with Buttons.
3. After that, your alarm volume will never change, even when you change the system volume with the side buttons.

Tip 2. Reboot Your iPhone

Many minor bugs on iPhone can be easily fixed by rebooting the device. Follow the easy steps to restart your iPhone:

1. Press and hold the Power button (or the Power button and either Volume button) until you see the power-off slider.
2. Drag the slider from left to right to power off the iPhone.
3. Wait for a few seconds and hold down the button again to turn your iPhone back on.

Tip 3. Choose A Louder Alarm Sound

Some of the iPhone alarm sounds are quieter than others. Make sure that the alarm sound you choose is strong enough to wake you up. Here's how to change the iPhone alarm sound:

1. Open the Clock app, and in the Alarm section, tap on Edit.
2. Select the alarm that you wish to change the sound.
3. Tap on Sound, and from the list of ringtones, choose a louder one. Be careful not to set the alarm sound to None.

Tip 4. Check Alarm's Time Settings

If your iPhone alarm is set for the wrong day or time, it also doesn't ring as expected. In this case, you'd better check and review the alarm settings.

1. In the Alarm section of the Clock app, click on Edit in the upper-left corner.
2. Tap on the alarm you need to check.
3. In the settings, ensure that AM/PM and Repeat are set correctly, then tap on Save.

Tip 5. Disable the Bedtime Feature

Some users have reported that the Bedtime feature interferes with their alarms and causes them not to go off. If you have enabled the Bedtime feature on your iPhone, you'd better turn it off. Here's how to do it:

1. In the Clock app, choose Bedtime from the bottom.
2. Tap on Bedtime and Wake and turn off Bedtime Schedule.

Tip 6. Delete and Recreate All Alarms

Your iPhone alarm may work for a while but then stop working because of software glitches or incompatibility issues. In such a case, you can try to delete all the alarms and then recreate them to fix the error.

1. Go to the Alarms tab in the Clock app.
2. Click Edit and tap the red minus button to remove each alarm. You can also delete an alarm by swiping left on it in the Alarm tab.
3. Then click on the plus button on the Clock App to create a new alarm.

Tip 7. Use Only One Alarm App

You may run into issues if you have more than one alarm app on your iPhone. Please note that third-party alarm apps are usually not well integrated with the built-in one.

To fix the iPhone alarm not going off, we suggest you turn off all the third-party alarm apps and use only the default alarm app. If disabling them didn't help to fix the problem, try to delete them completely and restart your iPhone.

Tip 8. Turn Off Bluetooth and Disconnect Headphones

iPhone alarms should not ring through any Bluetooth devices or headphones. Therefore, if your iPhone alarm is not working properly, please ensure to turn off Bluetooth from Settings and all external headphones/speakers are unplugged.

Tip 9. Update iOS to The Latest Version

Apple regularly releases new iOS versions to remove some unexpected bugs on previous versions. Thus any updates on iOS firmware will greatly improve the system performance for iPhone.

Check whether the iOS version is the newest one from Settings > General > Software Update on iPhone. Click Download and Install to install the newest iOS version if available.

Tip 10. Reset iPhone to Default Settings (Data Loss)

None of the solutions above resolve the issue? Factory resetting your iPhone is also a useful tip to try. This will delete everything on your iPhone, and the device will be restored to factory default settings, which helps to fix any software-related issues.

Before doing that, remember to back up your iPhone with iCloud, iTunes, or third-party FoneGeek iOS Backup & Restore to save your important data. To reset all settings on the iPhone:

1. Go to Settings and click on General.
2. Scroll down to the bottom and click Reset (Transfer or Reset iPhone in iOS 15 or later).
