How to Unsleep an App on Android
Unsleeping an app on Android removes battery optimization restrictions that prevent applications from running in the background. Users need this when apps stop sending notifications, fail to sync data, or don’t update content automatically.
This guide covers 4 steps requiring 2-3 minutes and Android 6.0 Marshmallow or later.
Prerequisites
- Android device with version 6.0 or higher
- Access to Settings menu
- Name of app you want to unsleep
- Time needed: 2-3 minutes
- Skill level: Beginner
Step 1: How Do You Access Battery Optimization Settings?
Navigate to Settings, tap Battery or Device Care (depending on manufacturer), then select battery optimization to view power management controls. Samsung devices use Device Care, while stock Android uses Battery directly.
Action
Settings location: Open Settings app from app drawer or notification shade.
Battery menu: Tap Battery (Pixel, OnePlus) or Device Care (Samsung, Xiaomi) or Battery & Performance (Xiaomi MIUI).
Expected result: Battery usage screen appears showing consumption graphs and optimization options.
Purpose
Accessing battery settings lets you control which apps Android’s Doze Mode and App Standby restrict. Without this access, you can’t modify background execution limits or disable adaptive battery for specific applications.
Step 2: Where Do You Find the App Sleep Settings?
Locate the sleeping apps list through Battery > App Power Management (Samsung), Battery > Battery Optimization (stock Android), or Battery > App Battery Usage (Xiaomi). The exact path varies by manufacturer and Android version.
Action
Samsung One UI: Battery > Background Usage Limits > Sleeping Apps or Deep Sleeping Apps.
Stock Android: Battery > three-dot menu (⋮) > Battery Optimization > All Apps dropdown.
Xiaomi MIUI: Battery & Performance > App Battery Saver > choose app from list.
List display: Apps currently in sleep mode appear with toggle switches or checkboxes.
Purpose
Finding the sleeping apps list reveals which applications Android restricted to save power. Apps in this list can’t run background processes, receive push notifications, or sync data when screen is off.
Step 3: How Do You Remove an App from Sleep Mode?
Select the app from the sleeping apps list, toggle the switch to OFF position, or tap the app name and choose “Remove” to disable battery restrictions. Confirmation happens instantly without additional prompts on most devices.
Action
Samsung method: Tap app in Sleeping Apps list, then Remove button, or long-press app and select Remove from list.
Stock Android method: Find app in Battery Optimization list, tap it, select “Don’t optimize” radio button, tap Done.
Xiaomi method: Battery & Performance > Choose Apps > locate app > toggle “No restrictions” option.
Visual confirmation: App disappears from sleeping apps list immediately or moves to “Never sleeping apps” section.
Purpose
Removing apps from sleep mode grants unrestricted battery usage, allowing background activity, push notifications, and automatic syncing. The app can now run background processes without Android’s power management interference.
Alternative Method: Using Developer Options
Enable Developer Options by tapping Build Number seven times in Settings > About Phone. Navigate to Developer Options > Standby Apps to manually set app standby bucket to “Active” instead of relying on system optimization.
Method Comparison
Standard Battery Settings: 2 minutes, beginner-friendly, covers most use cases, manufacturer interface varies.
Developer Options Method: 3-4 minutes, requires technical knowledge, provides granular control over app standby buckets (Active, Working Set, Frequent, Rare).
Choose standard settings for quick fixes. Choose Developer Options when troubleshooting persistent app hibernation issues or testing app behavior.
Step 4: How Do You Verify the App Is No Longer Sleeping?
Check the battery optimization list to confirm the app appears under “Not optimized” or disappeared from sleeping apps. Test notification delivery and background data sync to verify functionality restored.
Action
List verification: Return to Battery Optimization settings, filter by “Not optimized” apps, confirm app appears in this category.
Notification test: Wait 10-15 minutes with screen off, check if app sends expected notifications or updates content.
Battery usage check: Settings > Battery > Battery Usage shows app consuming power during screen-off periods if running properly.
Purpose
Verification prevents assuming changes worked when Android might revert settings. Some manufacturers override user preferences with aggressive power management, requiring additional steps to maintain unrestricted background activity.
Verification
Open the app after 30 minutes of inactivity to check if data synced. Send yourself a test notification through the app’s service to confirm push notifications arrive instantly.
Battery usage statistics should show the app consuming small amounts of power during idle periods. No consumption means background restrictions still apply despite settings changes.
Troubleshooting
Issue: App Returns to Sleep Mode Automatically
Solution: Disable Adaptive Battery in Settings > Battery > Adaptive Battery toggle OFF. Samsung users disable “Put unused apps to sleep” in Battery > Background Usage Limits.
Add app to “Never sleeping apps” list explicitly rather than just removing from sleeping apps list.
Issue: Manufacturer Battery Optimization Overrides Changes
Xiaomi MIUI solution: Settings > Apps > Manage Apps > [app name] > Battery Saver > No restrictions AND Autostart > enable toggle.
Huawei EMUI solution: Settings > Battery > App Launch > [app name] > toggle OFF “Manage automatically” > enable all three options (Auto-launch, Secondary launch, Run in background).
OnePlus OxygenOS solution: Settings > Battery > Battery Optimization > [app name] > Don’t optimize AND Settings > Apps > [app name] > Battery > Background activity > Unrestricted.
Issue: App Still Doesn’t Receive Notifications
Solution: Settings > Apps > [app name] > Notifications > verify all notification categories enabled, not just battery settings.
Check Do Not Disturb settings aren’t blocking app notifications. Clear app cache (Settings > Apps > [app name] > Storage > Clear Cache), restart device, test again.
Related Processes
After unsleeping your app, you might want to monitor which apps run in the background to verify changes worked. Managing background apps properly prevents battery drain while maintaining functionality you need.
Some users prefer locking specific apps instead of changing battery settings, while others want to hide apps entirely from their home screen without affecting background behavior.
FAQ on How To Unsleep An App On Android
What happens when an app goes to sleep on Android?
Android restricts the app’s background activity, preventing notifications, data syncing, and automatic updates. The app stops running background processes to conserve battery.
Sleeping apps won’t refresh content, send push notifications, or perform scheduled tasks until you open them manually.
Will unsleeping an app drain my battery faster?
Yes, but minimally. Apps with unrestricted battery usage consume more power during idle periods.
Most messaging and email apps use 2-5% additional battery daily. Social media apps with constant syncing drain 5-10% more.
Does unsleeping apps work on all Android versions?
Battery optimization exists on Android 6.0 Marshmallow and later. The feature works across all versions, though settings paths differ by manufacturer.
Samsung One UI, Xiaomi MIUI, and stock Android place controls in different menus.
Can Android automatically put apps back to sleep after I unsleep them?
Adaptive Battery can re-enable restrictions if you don’t use the app frequently. Samsung’s “Put unused apps to sleep” feature reapplies optimization after 30 days of inactivity.
Add apps to “Never sleeping apps” list for permanent exemption.
How many apps can I unsleep without affecting battery life significantly?
3-5 apps won’t noticeably impact battery. Beyond 10 unoptimized apps, expect 10-15% faster battery drain depending on app behavior.
Messaging apps use minimal power compared to location-tracking or social media apps with constant background refresh.
What’s the difference between sleeping apps and deep sleeping apps on Samsung?
Sleeping apps have moderate restrictions, allowing occasional background activity. Deep sleeping apps can’t run in background at all until manually opened.
Deep sleep completely blocks notifications, syncing, and all background processes for maximum battery savings.
Why won’t my app stay unsleeping after I change the settings?
Manufacturer battery optimization overrides user settings. Xiaomi, Huawei, and OnePlus devices require disabling Autostart permissions and app-specific power management separately.
Check both battery optimization and background data restrictions in app settings.
Is there a way to unsleep all apps at once?
No universal toggle exists. You must remove each app individually from the sleeping apps list.
Stock Android’s “Don’t optimize” filter shows all unrestricted apps but requires one-by-one selection for changes.
Does disabling battery optimization affect app security or privacy?
No. Battery optimization controls power consumption, not permissions. Apps can’t access additional data or sensors just because they’re unsleeping.
Privacy permissions remain separate in Settings > Apps > Permissions regardless of battery settings.
Can I unsleep system apps like Google Play Services?
Yes, though most system apps already bypass battery optimization by default. Google Play Services, Android System, and Device Care typically appear as “Not optimized.”
Manually optimizing system apps can break functionality like notifications and background syncing.
Conclusion
Knowing how to unsleep an app on Android restores the functionality you need without sacrificing all battery life. The process takes minutes once you locate your device’s power management settings.
Manufacturer differences matter. Samsung, Xiaomi, and Huawei hide sleep controls in different menus, requiring specific paths to disable app hibernation permanently.
Check your work. Apps sometimes return to sleeping apps lists thanks to aggressive battery saver features that override manual changes.
Keep the list short. Unsleeping every app tanks battery performance without real benefit.
Focus on apps sending time-sensitive notifications or requiring constant background data sync. Your messaging apps, email clients, and work tools deserve unrestricted access while games and social media can wait.
