iPhone alarm is a valuable feature that helps you wake up on time and get important reminders. Also, people’s circadian cycle depends on the iPhone’s clock app. But your schedule can become messy if the iPhone alarm is not working correctly.

There are a few scenarios, like you can’t hear the alarm sound or the iPhone is buzzing and blinking without any ringtone.

Therefore, this guide will help you fix the iPhone alarm by simple methods. You have to test the iPhone alarm after each method.

Methods to Fix iPhone Alarm

There are ten methods to fix the iPhone alarm not working issue. We’ll go through each one in detail. Also, you must follow each step carefully and set the alarm after each method to see if the issue is fixed.

Method #1: Restart iPhone

The first and easiest method is to restart your iPhone. No doubt, Apple’s products are full of high-tech features. But if there occurs any issue, it’s an expert suggestion to start with restarting that device.

Restarting a device solves minor software bugs and refreshes it.

Therefore, follow these steps to restart or soft reset your iPhone.

Restart Your iPhone 7

  1. Press the Power button until you see a slider on the home screen.
  2. Drag the slider to “Slide to power off.”
  3. Wait for 30 seconds till your device completely powers off.
  4. Again, hold the Power button till the Apple logo appears.

In case your iPhone doesn’t restart in the usual way, try force restarting it.

Force Restart Your iPhone 7

  1. Press and hold the Volume Down and Sleep/Wake buttons together.
  2. Once the Apple logo appears, release the buttons.

After successfully rebooting your device, check the iPhone alarm.

Besides, you can check here to learn how to restart or force reboot your iPhone if you have a different model.

Method #2: Increase the Alarm Sound

This method might look more accessible than the first one, but don’t overlook it.

The volume buttons on the side of your iPhone control different sounds, including the alarm, sounds as well. So you might have increased some sounds other than the alarm.

That usually happens when you watch a video or listen to music and press the volume buttons to adjust the volume. Now, if you are doing anything related to media and trying to adjust the alarm sound, you must adjust the alarm bar manually.

Therefore, increasing the music volume will not increase the alarm sound. So even if you set the alarm to that volume, that’s a silent alarm.

Follow these steps to keep the desired sounds constant even if you press the volume buttons:

  1. Open the Settings app.
  2. Go to Sounds.
  3. Select Sounds & Haptics
  4. Set the Ringer and Alerts slider to a suitable volume
  5. Also, there’s an option of “Change with Buttons.” Make sure to toggle it off so that alert ringers like the alarm sound will not change even if you press the volume button.

Now, test the alarm sound without waiting for it to go off.

  1. Launch the Clock app
  2. Go to Alarm
  3. Tap Edit
  4. Now, select an alarm from the list.
  5. Tap Sound
  6. Pick any ringtone from the available options. The volume you hear will be the same when the alarm goes off.

Manually Change Alarm Sound

If you want to change the sound of a particular alarm, you have to decrease the volume while setting the alarm manually.

Method #3: Disable Bedtime Feature

Before disabling this feature, let’s understand what Bedtime on iPhone is and how it differs from the Do Not Disturb mode.

What is the Bedtime feature on my iPhone?

This feature reminds you when to go to bed and wake up. Moreover, it uses the features of the Do Not Disturb mode and silences the following:

  • Incoming Calls
  • Text Messages Tones
  • Other Notifications

Now, you can set your Bedtime by following these steps:

  1. Open Clock app
  2. Tap the Bedtime tab. It’s located at the bottom of the screen.
  3. If it’s the first time you are setting Bedtime, tap Get Started
  4. Now, separately set the Bedtime and Wake time.

If you can’t find the Bedtime tab in the Clock, try finding it in the Health app. The latest iOS version has moved some health-related features in that app.

After you are done with the Bedtime settings, you don’t have to set the alarm for your sleep schedule.

However, if you set it simultaneously as the Bedtime settings, things might confuse your iPhone alarm. Why?

When it’s time for your alarm clock to go off?

Perhaps you have configured the same time for your Bedtime (or Wake time.) Therefore, neither of the alarms may go off.

Thus, you will get nothing but a silent alarm.

How to Disable Bedtime?

The best practice is to disable this feature because it causes the same problem as the silent alarm.

Follow these steps to disable Bedtime:

  1. Open the Clock app
  2. Tap the Bedtime tab at the bottom
  3. Toggle off Bedtime

Method #4: Set a Louder Alarm Tone

Since you can’t hear the alarm tone, it’s time to pick something louder to make sure you wake up on time.

Follow these steps to change the iPhone alarm sound:

  1. Open Clock app
  2. Go to the Alarm tab
  3. Tap Edit
  4. Now, select the desired alarm and simply tap Sound
  5. Here, you can preview different sounds, songs, and ringtones on your iPhone.
  6. Select anything suitable for you.

Besides, this method also ensures you haven’t selected None for the sound of the iPhone alarm. It’s similar to the silent alarm problem.

Method #5: Set Again the Alarm

Sometimes your iPhone might not follow the commands you gave while setting the alarm. That might be due to iPhone’s internal glitch, or it just has deleted the alarm due to a bug.

Therefore, the easy solution to fix the iPhone alarm is first to delete the alarm and then set it again.

Delete Alarm

  1. Open the Clock app
  2. Tap Alarm
  3. Select the alarm you want to delete and tap on the Edit button located in the upper left corner
  4. After that, tap the red minus sign. That’s the delete option. Alternatively, you can swipe the alarm slider left to delete an alarm.

Set Alarm

After you have deleted the alarm, it’s time to set a new alarm.

  1. Tap the plus button on the upper right-hand corner of the Clock app.
  2. Set the time of your alarm clock.

Method #6: Check the Time of the Alarm Clock

If you have set the alarm at 05:00 AM, it’s supposed to go off at that time. However, it does go off but only for a day. Therefore, there are two possibilities:

  • First, you haven’t set your alarm on repeat.
  • The time of the alarm clock is not correct.

Set Alarm Clock on Repeat

  1. Go to Clock >> Alarm tab >> Edit
  2. Select the alarm you want to turn its repeat settings on
  3. Tap Repeat and set the alarm clock repetition as you like

Adjust Correct Alarm Time

  1. While setting the alarm, ensure you correctly set the AM and PM settings.
  2. Tap Save once you have set the alarm correctly.

Method #7: The Alarm Clock App

No doubt, there are third-party alarm apps for iPhones. They are freely available on the Apple App Store. You can download and install them and use any one app instead of the iPhone’s alarm clock. But you have to stay vigilant of one thing.

Using a third-party alarm app, you always have to keep it open. Why?

A third-party app is not integrated with your iPhone’s system. So if you set the alarm on a third-party alarm app, make sure you have kept the app open. Only then will the alarm go off, and you will hear it.

Also, it’s recommended to use only one app to set alarms. If you try to go the other way, the existing alarm on the default iPhone alarm might not work either.

Additionally, you have to set its volume manually. But, of course, you can only do that if the app runs on your iPhone. The iPhone’s ringer volume settings will not affect this third-party application.

Now, if you are facing the same problem on the third-party app, follow these steps:

  1. AltogetherFirst, altogether remove that app from your iPhone.
  2. Reboot your iPhone.
  3. Set a new alarm on the iPhone’s default app.

Method #8: Turn Off Bluetooth and Disconnect Audio Devices

Usually, the alarm rings from the iPhone’s speakers. But that might not be the case if your iPhone has software issues.

The other way you might hear your alarm going off is through Bluetooth devices. So you will not hear anything from the iPhone’s speakers but the device connected to Bluetooth.

Therefore, you have to turn off Bluetooth on your iPhone.

Disable Bluetooth

  1. Open Settings
  2. Tap Bluetooth
  3. Toggle off Bluetooth

Also, unplug any audio devices from your iPhone before sleeping.

Method #9: Update iOS Device

One of the common reasons why the default iPhone apps stop properly working is due to outdated iOS versions. So that might be a reason for the iPhone alarm not working issue.

Therefore, you have to update your iPhone and check if the alarm issue is resolved or not.

Follow these steps to update the iOS of your iPhone:

  1. Tap Settings on the iPhone app screen
  2. Select General
  3. Tap Software Update
  4. Tap Download and Install

Method #10: Reset Your iPhone

If the above methods didn’t solve the issue, it’s to factory reset your iPhone.

Hard resetting will restore iPhone to its factory default settings. That means it will also restore the alarm and other customized settings.

Therefore, follow these steps to factory reset your iPhone:

  1. Open iPhone Settings
  2. Go to General
  3. Tap Reset
  4. Select Erase All Content and Settings

Your iPhone might ask you to enter the device passcode before resetting it. Also, you can go for DFU mode to restore your iPhone.

Once the hard reset is done, all the settings will come to factory defaults, including the iPhone alarms.


Why is the Alarm on My iPhone Not Working?

There might be issues with the iPhone’s software. To resolve these issues, follow the fixes mentioned above.

You can also check the iPhone’s Mute Switch. So please turn it off and see whether the alarm clock is working correctly.

Why Sometimes is My Alarm Not Working?

The alarm volume is either set too low, or you have set the wrong alarm time. Try editing the alarm time and see if it goes off at the set time.

Why Does My Alarm Go Off But No Sound?

The silent alarm issue might be due to the same time of

  • iPhone alarm
  • Third-party alarm
  • Bedtime

Change or disable the apps and use only one to set all the alarms on your iPhone.
