Alarm Didn’t Go Off on Your iPhone 11? Here’s How to Fix It

Did you miss an important event or was not able to get up early because the alarm on your iPhone 11 failed to ring? In this article, I’ll explain why your iPhone 11 alarm is not working and show you how to fix the problem, step-by-step.

One of the more basic functions our iPhones have that we use so often and sometimes overlook is telling the time. It is such a simple yet integral function of an iOS device. The clock app on iPhones also allows its user to set up timers and alarms. Several users have discovered that their iPhone 11 alarm is not working. If you are also having the problem of iPhone 11 alarm not ringing off when needed, here are the steps to fix the issue.

Fixes for alarm not working on iPhone 11

Here are some things to try if your iPhone 11 alarm didn’t go off.

Note: The information in this article applies to iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max.

Restart your iPhone

As with any problem with smartphones, the first thing to try when your iPhone 11 alarm is not working is to reboot your device. This helps in a couple of ways.

Firstly, it clears the temporary cache so that any minor changes will be reset to their normal state upon reactivation. In addition, it clears the RAM, which stores the bits of data that you used while your phone was malfunctioning. You can restart your iPhone by going to Settings > General > Shut Down.

Turn Up The Ringer Volume

This might sound obvious, but don’t skip over this step. It’s actually possible to turn up the volume with the buttons on the side of your phone without actually increasing the alarm volume. This is because the iPhone 11 lets you control two completely different sets of sounds with the same buttons.

For example, if you have a music streaming app open, using the buttons will control that volume instead of the alarm volume. This means that if your alarm volume is down or off (even if your music volume is up), you’ll have a silent alarm.

Go to Settings > Sounds & Haptics, and make sure RINGER AND ALERTS is set to a reasonable volume. Also here is the Change with Buttons option, which you should disable if you want to make sure the ringer and alarm volume never change when you change the system volume with the buttons.

To test the sound without waiting for the alarm to go off, open Clock > Alarm, tap Edit, and select an alarm. Go to Sound and pick a ringtone from the list; if you can hear it, it should work just fine when the alarm actually goes off.

Change the alarm sound

Some of the iPhone 11 alarm sounds are quieter than others, so if you have one of those chosen—and especially if the alarm volume isn’t loud, either—you might not hear it go off. Something else to watch out for is to make sure None isn’t chosen as the alarm sound, for obvious reasons.

Open the Alarm tab, tap Edit, and then choose the alarm you want to change the sound for. Go to Sound and preview the ringtones or songs to find something you think will work for you.

Check the Alarm’s Time Settings

If your alarm goes off but it’s silent, then this method won’t help you. However, for iPhone 11 alarms that are set in the app but that don’t go off at the designated time, you might not have the correct time or day set up.

For instance, if your alarm is supposed to go off every day at 10:30 PM, and it worked yesterday but not today, the alarm is most likely not set up to repeat.

Click Edit in the Alarm section of the Clock app, and then tap the alarm you need to edit. Go into the Repeat settings and make sure there’s a checkmark next to the days of the week for when you want the alarm to go off. Just tap a day to enable or disable the alarm for that day.

If your alarm goes off at the wrong time during the day, then you most likely confused AM and PM, which is surprisingly easy to do. Edit the alarm and change it to the appropriate time of day, and be sure to tap Save when you’re done.

Disable Bluetooth and Unplug Headphones

iPhone 11 alarms should ring through the phone’s speakers and not any Bluetooth devices or headphones. However, that might not always be the case.

If your iPhone 11 has a software bug or is behaving erratically, it might try to play the alarm through those devices if they’re actively attached to your iPhone while the alarm sounds.

Depending on how you’ve got your volume and ringer settings configured, and where these accessories are located when the alarm goes off, you might end up hearing nothing.

Turn off Bluetooth from Settings > Bluetooth, and unplug anything attached to the headphone jack. If the alarm works after doing those things, then be fully aware of when your alarms will go off, and make sure that your audio accessories are not connected to your phone during those times.

Delete and Remake the Alarm

For whatever reason, the iPhone 11 might not have created the alarm correctly. Or, maybe it worked for a while but then stopped because of a glitch or incompatibility issue after an iOS update.

Open the Clock app to the Alarm tab, and either swipe left to delete the alarms or go to Edit first and then tap the red minus buttons to find the Delete option. You can make new iPhone alarms with the plus button on the upper right-hand corner of the Clock app.

Many users with iPhone 11 alarm sound problems are using an outdated version of iOS. There could be a software bug in your phone that’s only resolved through an update from Apple.

You can update your phone by going to Settings > General > Software Update, or plug it into your computer and update with iTunes. Either way, make sure you’re using the most up-to-date firmware version.

Reset All Settings

This should be the very last thing you do to fix an iPhone 11 alarm that has no sound because when you restore your iPhone, everything in the Settings app is restored to factory defaults. In the process, it should also fix any iPhone 11 alarm issues. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings.
