Missing notifications can make you miss messages, updates, or reminders without realizing it. On the Realme 16, this usually happens when background activity is restricted or notifications are silently blocked. The fixes below focus on restoring proper background access so alerts arrive on time again.
Why Background App Notifications Are Not Working on Realme 16
- Battery optimization is restricting apps in the background.
- Background data is disabled for specific apps.
- Notification permissions are turned off or limited.
- Do Not Disturb or focus modes are active.
- System optimization is closing apps too aggressively.
1. Turn Off Battery Optimization for Affected Apps
Battery optimization can stop apps from running in the background, which prevents notifications from being delivered. Disabling it for important apps allows them to stay active and send alerts normally.
Open Settings, and then tap Battery.
Tap App battery management, and then select the affected app.
Choose Allow background activity, and then set it to No restrictions.
2. Allow Background Data Usage
If background data is blocked, apps cannot sync or push notifications when you are not actively using them. Enabling background data restores real time alerts.
Open Settings, and then tap Mobile network.
Tap Data usage, and then select App data usage.
Choose the affected app, and then enable Background data.
3. Check App Notification Permissions
Notifications may be disabled at the app level without you noticing. Confirming permissions ensures alerts are allowed to appear on the lock screen and notification panel.
Open Settings, and then tap Notifications and status bar.
Tap App notifications, and then select the affected app.
Enable Allow notifications, and then turn on Lock screen notifications.
4. Disable Do Not Disturb Mode
Do Not Disturb can silence notifications entirely or allow only priority alerts. Turning it off restores normal notification behavior.
Open Settings, and then tap Notifications and status bar.
Tap Do Not Disturb, and then switch it off.
Check that no schedules are enabled.
5. Lock Apps in Recent Apps Screen
Realme phones may close background apps aggressively to save power. Locking important apps prevents them from being cleared from memory.
Open Recent apps, and then locate the affected app.
Tap the app icon, and then select Lock.
Keep the app running in the background.
6. Restart Your Phone
A restart refreshes system services responsible for notifications. It also clears temporary glitches that block background alerts.
Press and hold the Power key, and then tap Restart.
Wait for the device to reboot, and then test notifications again.
Once background restrictions are removed, notifications on the Realme 16 usually return to normal. Keeping battery and data permissions properly configured helps ensure alerts stay reliable throughout the day.
FAQs
Why do notifications arrive only when I open the app?
This usually means background activity or background data is disabled. The app cannot sync unless it is actively opened.
Does battery saver affect notifications on Realme 16?
Yes. Battery saver limits background processes, which can delay or block notifications for many apps.
Should I update the app if notifications still fail?
Yes. App updates often fix notification bugs and improve compatibility with the system, especially after software updates.
