Missing Snapchat notifications on your Xiaomi 15 Ultra can make you miss messages, snaps, and calls without realizing it. This issue often happens silently, where Snapchat is working fine but alerts never appear. In most cases, the problem is caused by notification permissions, battery restrictions, or background limits that stop the app from running properly.
Why Snapchat Notifications Are Not Working on Xiaomi 15 Ultra
- Notifications are disabled for Snapchat in system settings.
- Battery optimization is restricting Snapchat in the background.
- Background data or autostart is turned off.
- Do Not Disturb mode is blocking alerts.
- The Snapchat app cache is corrupted or outdated.
1. Check Snapchat Notification Permissions
Notifications must be fully enabled at the system level, otherwise Snapchat cannot alert you even if in-app notifications are turned on. This step ensures the app is allowed to display banners, sounds, and lock screen alerts.
Open Settings, and then tap Notifications.
Tap App notifications, and then find and tap Snapchat.
Enable all notification types, including Lock screen, Floating notifications, and Sounds.
2. Turn Off Battery Optimization for Snapchat
MIUI aggressively manages background apps to save battery. If Snapchat is restricted, notifications may be delayed or completely blocked.
Open Settings, and then tap Battery.
Tap App battery saver, and then select Snapchat.
Choose No restrictions to allow Snapchat to run freely in the background.
3. Enable Autostart for Snapchat
Autostart allows Snapchat to relaunch itself in the background after the phone restarts or clears memory. Without this, notifications may stop after some time.
Open Settings, and then tap Apps.
Tap Manage apps, and then find and tap Snapchat.
Enable Autostart so the app can run in the background.
4. Allow Background Data Usage
Snapchat relies on background data to receive new messages and alerts. If background data is restricted, notifications will not arrive in real time.
Open Settings, and then tap Apps.
Tap Manage apps, and then select Snapchat.
Tap Data usage and enable Background data.
5. Check Do Not Disturb Settings
Do Not Disturb mode can silence notifications even when everything else is configured correctly. This is easy to overlook, especially if it is scheduled.
Open Settings, and then tap Sound and vibration.
Tap Do Not Disturb, and check if it is enabled or scheduled.
Turn it off or add Snapchat as an exception.
6. Clear Snapchat Cache
A corrupted cache can prevent notifications from syncing properly. Clearing it refreshes the app without deleting your account or messages.
Open Settings, and then tap Apps.
Tap Manage apps, and then select Snapchat.
Tap Storage, and then tap Clear cache.
7. Update Snapchat
Outdated versions of Snapchat may not work well with newer system updates. Updating the app ensures compatibility and fixes known notification bugs.
Open the Google Play Store, and then tap your profile icon.
Tap Manage apps and device, and then update Snapchat if available.
Once Snapchat notifications are restored, alerts should arrive instantly again on your Xiaomi 15 Ultra. Most notification issues are caused by background restrictions, and once those are removed, the app works reliably.
FAQs
Why do Snapchat notifications only appear when I open the app?
This usually means background activity is restricted. Disabling battery optimization and enabling background data fixes this behavior.
Does Xiaomi block notifications by default?
Yes. Xiaomi phones apply aggressive battery and background controls by default, which often affects messaging apps like Snapchat.
Will clearing cache delete my Snapchat messages?
No. Clearing cache only removes temporary files and does not delete chats, snaps, or your account data.
