If Facebook notifications suddenly stop appearing on your Xiaomi 15 Ultra, it is easy to miss messages, comments, or important alerts. This issue usually happens because of background restrictions, notification settings, or aggressive battery management in MIUI. The good news is that most notification problems can be fixed in just a few minutes with the right adjustments.
Why Facebook Notifications Are Not Working on Xiaomi 15 Ultra
- Notifications are disabled for Facebook in system settings.
- Battery saver or background restrictions are limiting Facebook activity.
- Facebook is not allowed to run in the background.
- Notification categories inside Facebook are turned off.
- Temporary app glitches after an update or long uptime.
1. Make Sure Facebook Notifications Are Enabled
Facebook cannot send alerts if notifications are blocked at the system level. This is often overlooked, especially after a software update or permission reset.
Open Settings, and then tap Notifications.
Tap App notifications, and then find and tap Facebook.
Turn on Allow notifications, and make sure all alert types are enabled.
2. Allow Facebook to Run in the Background
If background activity is restricted, Facebook cannot check for new updates or messages. This causes notifications to arrive late or not at all.
Open Settings, and then tap Apps.
Tap Manage apps, and then tap Facebook.
Tap Battery saver, and select No restrictions.
3. Disable Battery Saver Mode
Battery saver mode limits background processes to extend battery life. When enabled, it often blocks real time notifications from social apps like Facebook.
Open Settings, and then tap Battery.
Tap Battery saver, and turn it off.
Lock your phone and wait a few minutes to see if notifications arrive.
4. Check Facebook In-App Notification Settings
Even if system notifications are enabled, Facebook may still block alerts internally. You need to confirm that the specific notification types you want are turned on.
Open the Facebook app, and then tap the Menu icon.
Tap Settings and privacy, and then tap Settings.
Tap Notifications, and make sure alerts for comments, messages, and activity are enabled.
5. Clear Facebook App Cache
Corrupted cache files can prevent notifications from syncing properly. Clearing the cache refreshes the app without deleting your account or data.
Open Settings, and then tap Apps.
Tap Manage apps, and then tap Facebook.
Tap Clear data, and then tap Clear cache.
6. Restart Your Phone
A restart refreshes background services and reconnects the notification system. It is a simple step, but often effective.
Swipe down from the top of the screen to open Quick Settings.
Tap the Power icon, and then tap Restart.
Wait for the phone to boot up and check for notifications.
Facebook notifications on the Xiaomi 15 Ultra usually stop working because the system is trying to save power. Once you remove restrictions and allow background activity, alerts should start coming through normally again.
FAQs
Why do Facebook notifications only appear when I open the app?
This usually means background activity is restricted. Setting Facebook to No restrictions in battery settings fixes this behavior.
Do Xiaomi phones block notifications by default?
Xiaomi devices use aggressive battery management. Some apps need manual permission to run freely in the background.
Should I reinstall Facebook if notifications still do not work?
Reinstalling can help if the app is corrupted, but you should try adjusting notification and battery settings first, since those are the most common causes.
