Why Did My iPhone Alarm Randomly Go Off? 

Your iPhone alarm may be randomly going off for a number of reasons. While the sound of an iPhone alarm is sure to get anyone moving, you certainly don’t want to hear it if you didn’t set it. There can be a couple of different reasons why your alarm may be going off seemingly at random.

I discuss all this and more below. 

How Do I Get Rid of the Ghost Alarm?

If you need to get rid of a ghost alarm on your iPhone, there’s a number of things you can do. Let’s take a look at some solutions. 

Covering the Basics

If you’re experiencing issues with your iPhone alarm randomly going off, there’s a couple of simple things you can try first. While these are not guaranteed to solve your problem, they might. However, it may be a good idea to perform many of these tasks anyway. 

First, make sure your iPhone is up to date. Try your best to stay current with the latest operating system for any device. You can check your iPhone by going to Settings > General > Software Update. If one is available, update your device. 

It’s also a good idea to force restart your iPhone. This may eliminate any ghost alarms occurring on your device. To force restart your iPhone if you have Face ID (no Home button), press and immediately release the volume up button, then press and immediately release the volume down button. Lastly, press and hold the power button until you see the Apple logo. 

For the iPhone 7, you will press and hold the volume down along with the Sleep/Wake button. Wait for the Apple logo to appear. For the iPhone 6s or iPhone SE, you will press and hold the Sleep/Wake button and the Home button. Hold until the Apple logo appears. A nice force restart may just do the trick.

Users should also remove any third-party alarm apps until they figure out their problem. You can remove an app by pressing and holding on the app, then selecting Remove App > Delete App > Delete from the pop-up window.

Remove and Reset iPhone Alarms

One of the first things you should check is your Alarms in the Clock app. There may be an Alarm set that you forgot about, or you may have accidentally set multiple alarms. Personally, I would recommend deleting them all and starting over from scratch, but once you know what to do, you can determine for yourself which ones you want to delete.

  1. Open the Clock app on your iPhone and choose Alarm from the bottom.
  2. To delete an Alarm, swipe left on it and tap Delete.

  3. You can set new Alarms with the + button in the top-right corner. You can also hit the Edit button at the top to remove Alarms.

Disable Bedtime Feature

Some users may forget about this feature, but the Health app does include Sleep options, which also features a setting that allows users to have their device remind them when it’s time to go to bed and when it’s time to wake up. This Sleep setting will play an alarm for each. This may be a setting users should check if they’re experiencing ghost alarms. 

Time needed: 1 minute

To check if you have Sleep notifications turned on:

  1. Open the Health app.

  2. Go to Browse and then select Sleep.

  4. Toggle the Sleep Schedule button to off.

As a last resort, you can always reset all of the settings on your iPhone. While this isn’t entirely a “going nuclear” option, it is going to erase all of the settings across all of your stock iPhone apps. 

Go to Settings > General > Reset > Reset All Settings to bring your iPhone settings to default.
