Then test Power saving, Data Saver, Do not disturb, and the app’s notification settings. Change one setting at a time so you can identify what is delaying alerts without loosening battery controls for every app.
Start by checking which notifications are delayed
Notice whether the problem affects one app or several, and whether alerts are late only while the phone is idle or locked. If alerts arrive on time but make no sound or do not appear on the lock screen, the issue may be notification visibility or Do not disturb rather than delayed delivery. These clues help choose what to check first; they do not prove a single cause.

Check whether the app is sleeping
Samsung warns that apps in Sleeping apps may run intermittently, delaying updates or notifications. Deep sleeping apps do not run in the background; Samsung says their updates and notifications arrive only when you open them. See Samsung’s guide to managing sleeping apps.
- Open Settings > Battery > Background usage limits. If your menus differ, search Settings for “Background usage limits.”
- Check Sleeping apps and Deep sleeping apps for the affected app.
- Remove it from either list if you need timely alerts. If the phone continues restricting it, add it to Never sleeping apps, if that option is available.
Samsung notes that feature availability can vary. Allowing an app to run without sleeping may use more battery, so reserve that exception for apps where timely background activity matters, such as messaging or navigation.

Test Power saving and Data Saver
Power saving
Power saving can limit background network use and syncing. Temporarily turn it off and see whether notifications arrive promptly. Depending on your software version, the control may be under Settings > Device care > Battery > Power saving or another Battery menu. Samsung describes the feature and menu differences in its Device Care guidance and notification troubleshooting steps.
Data Saver
If delays continue, check whether Data Saver is restricting background data. Samsung includes Data Saver among the settings to review when apps are not sending notifications. Menu names and available controls can differ by phone and software version; search Settings for “Data Saver” if needed.

Check Do not disturb and notification settings
- Temporarily turn off Do not disturb, or review its schedule and exceptions. A schedule can suppress alerts at particular times.
- Open Settings > Notifications > App notifications, select the affected app, and confirm its notifications are enabled.
- If alerts seem to arrive but are missing while the phone is locked, check the app’s lock-screen notification settings. Samsung’s notification settings guide explains the relevant controls.
Distinguish a missing sound or lock-screen display from an alert that the app itself delivered late: changing background settings will not fix a notification that is merely hidden or silenced.

Update the app and phone, then retest
- Install any available update for the affected app through its app store.
- Check for available phone software updates in Settings.
- Restart the phone.
- Test notifications while the phone is idle. If you temporarily disabled Power saving, restore your preferred setting and test again.
Samsung recommends updates and restarting as troubleshooting checks, but neither is a guaranteed fix; delivery can also depend on the app and its service. Its notification troubleshooting page lists additional checks.

If only one app is still affected
Review that app’s own notification, sync, and account settings, then contact its developer if the problem persists. If the affected app is inside Secure Folder, follow Samsung’s Secure Folder notification troubleshooting steps, which cover notification settings, background restrictions, restarting, and updates.

Settings labels and paths vary across Galaxy models, software versions, and markets. Samsung’s newer guidance uses Settings > Battery > Background usage limits; older versions may use Settings > Device care > Battery > App power management. If a path does not match your phone, search Settings for the named feature rather than assuming the option is missing. Samsung’s application management documentation describes how background app management works.
