1. Check the Volume on iPhone

Sometimes, an alarm not going off may be simply because you forgot to turn up the ringer volume on your iPhone. The same applies if the overall volume is too low. The alarm volume and the general volume on an iPhone are controlled differently. Hence, you may have turned up the overall volume without increasing that of the alarm.


  1. Open Settings.
  2. Tap Sounds & Haptics.
  3. Pull the RINGER AND ALERTS slider and set it to a loud enough volume. You may also use the iPhone's volume buttons instead of pulling the slider.
  4. Turn Up Your Iphone’s Alarm Volume

2. Check Alarm Settings

It is common for an alarm to malfunction because you set it off incorrectly. For example, maybe you used the 12-hour clock system and mixed up AM and PM. Or you needed a daily alarm, but you set it to go off only once. Thus, check that you have set the alarm time correctly, then ensure it's on repeat mode if you need it daily.

Steps to set the correct time:

  1. Open the Clock app.
  2. Tap Alarm at the bottom, then ensure your alarm or alarms are set to the correct time, including AM and PM. Also, ensure the alarm is turned on by ensuring the toggle beside it is green.
  3. To edit an alarm, click Edit, then select the one you need to adjust. Once you are done, hit Save.

Steps to put an alarm on repeat mode:

  1. Go to Clock > Alarm.
  2. Select the alarm you want to repeat. Alternatively, tap Edit, then choose an alarm.
  3. Tap Repeat, and pick the days you would like it to ring. A checkmark will appear beside each selected day.
  4. Set Alarm to Repeat

  5. Press Back > Save.

3. Set a Specific Alarm Noise

Since some alarm tones are quieter than others, it is possible not to hear them ring, especially if the alarm volume is not loud enough.

If you do not wish to readjust the alarm volume, pick a more audible tone. You should also check that the alarm tone is not set to None since this means the alarm will go off silently.


  1. Open Clock > Alarm > Edit.
  2. Select the alarm whose sound you need to reconfigure.
  3. Tap Sound, then select a tone. A checkmark will appear next to the sound you choose.
  4. Change the Alarm Sound

  5. Hit Save in the upper-right corner.

4. Disable or Change the Bedtime Feature

You need to adjust or disable the Bedtime feature/ Sleep mode. The Bedtime feature, also known as Sleep mode, can cause your alarm not to go off when it is enabled. This usually happens when the Sleep feature is set to a time that interferes with an active alarm.


  1. Open theHealth app.
  2. Tap Sleep. In iOS versions older than iOS 15, go to Clock > Bedtime.
  3. Select Full Schedule & Options > Edit.
  4. Tweak the Bedtime Feature

  7. If you prefer deleting the sleep schedule, scroll down and tap Delete Schedule.

5. Delete and Remake the Alarm

The alarm not going off issue can also be ambiguous, meaning it's hard to pinpoint an exact cause. For example, it can occur due to an iPhone glitch or an update incompatibility. Fortunately, in many such cases, you can eliminate the problem by deleting the existing alarms and setting new ones.


  1. Open Clock > Alarm.
  2. Swipe left on an alarm, and hit Delete. Alternatively, tap Edit, hit the Delete button (red minus button), then tap the red delete icon next to each alarm.
  3. Tap the Plus '+' button in the upper-right corner to create a new alarm.
  4. Select the time for the alarm. You can also tweak the repeat frequency, add a label to the alert, and select a tone.
  5. Tap Save.

6. Disable Bluetooth and Unplug Headphones

Typically, an alarm on an iPhone will ring via the device's speakers even if the iPhone is connected to headphones or a Bluetooth device. However, if your iPhone has a glitch or a software bug, it could play the alarm tone via the connected devices.

This means you may hear or miss the alarm depending on the loud the attached audio device is. To avoid this, disconnect all connected or plugged-in gadgets.

Steps to turn off Bluetooth:

  1. Open Settings > Bluetooth.
  2. Tap the button next to Bluetooth to turn it off.
  3. Turn Off Bluetooth.

    Turn Off Bluetooth

  4. Or, swipe down from the top of your screen to open the Control Center, then tap the Bluetooth icon to turn it off.

7. Restart Your iPhone If you still can't fix the alarm problem

Restarting your iPhone is also known as a soft reset and is effective in fixing minor glitches and problems, some of which can cause this alarm issue. Since iPhones don't have a restart option, you must turn it off and back on.

Steps For iPhone X, 11, 12, and later:

  1. Press either volume button, and the power/side button, then hold them until the power-off slider comes up.
  2. Alt text: Restart iPhone X, 11, and later.

  4. Press the top button to power on your iPhone, then hold it until you see the Apple logo.

8. Use Only One Alarm Clock App

You may install a third-party alarm app on your iPhone. However, since using multiple alarm apps can lead to issues, you must first disable the default alarm clock app.

Beware that after-market apps do not integrate with your iPhone as efficiently as the stock app. For example, you may need to adjust the alarm volume using the overall system volume. If a generic app doesn't work, uninstall and delete it, restart your device, and try the default app again.

9. Don't Use Your Apple Watch to Set an Alarm

There have been numerous reports by iPhone users that setting the alarm using their Apple watch doesn't work. Suppose you have done so and are experiencing issues, try setting it directly via the Clock app on your iPhone. This lets you ensure the device's alarm is set up and active.

10. Get the Latest iOS

It is common for people using an outdated iOS version to experience this alarm not going off problem. Hence, you should update your iOS version. Also, iOS updates tend to fix glitches and bugs on the entire iPhone, effectively eliminating this issue.


  1. Open Settings.
  2. Tap General > Software Update.
  3. If there is an available download, click Download and Install.
