How to Fix OnePlus 13 Clock App Not Working

The Clock app is one of the most essential tools on your OnePlus 13. You rely on it for alarms, timers, and reminders. But when it stops working, fails to open, or alarms don’t ring, it can disrupt your routine.

This issue can happen for several reasons, from app glitches to system restrictions. Let’s go through the possible causes and practical fixes.

Why the OnePlus 13 Clock App Might Not Be Working

• The Clock app cache or data is corrupted.
• Battery optimization is restricting background activity.
• App permissions are missing.
• Outdated system software or app version.
• Temporary software glitch or misconfiguration.

Clear the Clock App Cache and Data.

Corrupted cache files can stop the Clock app from working correctly. Clearing them helps refresh the app without deleting your saved alarms.

1. Open Settings, and then tap Apps.
2. Tap App management, and then tap Clock.
3. Tap Storage usage, and then tap Clear cache.

If the problem continues, tap Clear data to reset the app completely.

Disable Battery Optimization for the Clock App.

Battery optimization can prevent the Clock app from running in the background, which may stop alarms from ringing.

1. Open Settings, and then tap Battery.
2. Tap Battery optimization, and then find and tap Clock.
3. Select Don’t optimize to allow the app to run freely.

This ensures the Clock app functions normally even in standby mode.

Check App Permissions.

If certain permissions are denied, the app might fail to send alerts or notifications.

1. Open Settings, and then tap Apps.
2. Tap App management, and then tap Clock.
3. Tap Permissions, and then allow access to Notifications and Alarms & reminders.

Now try setting a test alarm to check if the issue is resolved.

Update the Clock App and System Software.

Running older software can lead to compatibility problems. Updating ensures you have the latest bug fixes.

1. Open Settings, and then tap About device.
2. Tap OxygenOS, and then check for system updates.
3. Also, open the Play Store, and then tap your profile icon. Tap Manage apps & device, and update the Clock app if available.

Restart Your OnePlus 13.

A simple restart clears minor system glitches that may interfere with app performance.

Press and hold the Power key until the restart option appears. Tap Restart, and wait for your phone to boot up again.

Once it restarts, open the Clock app to see if it functions correctly.

Reset App Preferences.

If other apps or background restrictions are affecting the Clock app, resetting app preferences can help.

1. Open Settings, and then tap Apps.
2. Tap App management, and then tap the three dots at the top-right corner.
3. Tap Reset app preferences, and then confirm.

This restores all app defaults, which can fix hidden restrictions or notification issues.

The Clock app on your OnePlus 13 should now work normally. Keeping your phone updated and avoiding aggressive battery settings ensures your alarms and timers always go off as expected.
