How to troubleshoot iPhone XS Max with alarm function that’s not working?

Before troubleshooting, check the alarm sound on your iPhone XS Max by launching the Clock app. Then tap Edit to select an alarm and tap sound to check.

If you happen to download and install a third-party alarm app on your iPhone XS Max, then try to disable or remove it. Doing so will help you rule out app conflicts.

Test to see if the alarm function is already working. If it’s still not, then move on and start troubleshooting software problems that may have inflicted troubles on the phone’s alarm function or clock system.

First solution: Adjust the Alarm Volume on your iPhone XS Max.

Your alarm sound level may be too low that you could barely hear it and thus you missed the alarm. To make sure this isn’t the issue, check and manage the ringer and alerts sound level on your iPhone Xs Max with these steps:

  1. Tap to open the Settings app.
  2. Select Sounds & Haptics.
  3. Navigate to Ringers and Alerts.
  4. Then drag the slider left or right. You should hear an alert sound playing as you drag the slider.
  5. Set the loudness to a desired level.

Pressing the Volume buttons on the side of your iPhone will not affect or change the alarm volume unless you enable the option to Change with Buttons.

Second solution: Manage or delete other existing alarms then set up a new one.

If you’ve previously set up multiple alarms, there’s a tendency that you’ve selected the wrong alarm. So chances are that you didn’t hear your alarm sound because it’s set to a later date and time or the alarm sound was set to none. To rule this out, manage and/or delete any unused alarms from your iPhone XS Max with these steps:

  1. Tap to open the Clock app.
  2. Go to the Alarm tab.
  3. Tap Edit on the top-left corner of the screen.
  4. Tap to select the alarm you want to make changes with.
  5. Also make sure that the alarm sound is not set to None or else you won’t hear it sound.
  6. Then tap Save to apply the changes.
  7. To delete existing alarms on your phone, you can swipe left over the alarm you wish to delete and then tap Delete. Alternatively, you can tap Edit, tap the Minus (-) icon then tap Delete to confirm.

After deleting unused alarms, set up a new sample alarm to see if the problem is gone. You can also ask Siri to set the alarm for you. Just say Hey Siri, set an alarm for [desired time].

Third solution: Reset all settings on your iPhone XS Max.

Customized settings on your iPhone can also cause conflict to your alarm settings. This is likely to blame if your alarm was working fine and suddenly stopped working after applying some changes on your phone settings. To clear this out, follow these steps to reset all settings on your iPhone XS Max. This reset will erase all customized settings without affecting internal data stored on the phone memory. Here’s how it’s done:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Scroll down to and tap Reset.
  4. Select Reset all settings option.
  5. If prompted, enter your device passcode to continue.
  6. Then tap the option to confirm all settings reset.

Reboot your iPhone after the reset then enable features and options you want to use on your device.

Fourth solution: Download and install new software update for your phone.

Installing the latest iOS version on your iPhone may also address the issue if what you’re dealing with is the so-called alarm bug. If your iPhone is connected to Wi-Fi, has at least 50 percent battery life and enough storage space, then updating iOS via over-the-air is possible.

  • To check for new updates, go to Settings-> General-> Software update menu.

If a new iOS version is available, you should see an update notification that gives you options to Download and Install new update.

After updating, reboot/soft reset your iPhone XS Max to apply the recent system changes and to clear cache on the phone memory and system folders.

Fifth solution: Wipe your iPhone XS Max then restore to its factory defaults (master reset).

If you the alarm is still not working after applying all prior workarounds, then you may opt to troubleshoot further and resort to a factory reset. What you’re dealing with could be due to some fatal system errors that require advanced solutions. At this point, backing up of critical data is recommended. Once you’re all set, factory reset your iPhone Xs Max with these steps:

  1. Tap to open Settings app from Home.
  2. Tap General.
  3. Scroll down to and tap Reset.
  4. Select the option to Erase all content and settings.
  5. When asked, enter your device passcode.
  6. Then tap the option to confirm master reset.

Your phone will then start wiping data and then restore factory defaults. When the reset is finished, your device restarts by itself. Allow it to boot up then set up your iPhone Xs Max as new and then create a new test alarm with these steps:

  1. Open the Clock app from the Home screen or through the Control Center.
  2. Go to the Alarm tab.
  3. Tap the Plus (+) sign then set a desired time for the alarm.
  4. To set up a recurring alarm, tap Repeat.
  5. To select a sound that plays when the alarm sounds, tap Sound.
  6. To set a name for your alarm, tap Label.
  7. Finally, tap SAVE to create and activate your alarm.

Check and see if your alarm works. If it’s not, then you’re most likely dealing with a complex system error that may have caused the iPhone XS Max alarm system to malfunction.

For Bedtime alarms to be heard, be sure not to enable Do Not Disturb During Bedtime option as this will silence all calls and alerts that arrive when your phone is locked. Also ensure that the Wake Up Sound level is set to the highest.
