Android battery optimization can limit background apps and delay notifications. Learn why apps close and how to keep important apps running reliably.
Android battery optimization can restrict an app’s background work delay network access, and sometimes make it appear as if the app has been “closed.” The safest fix is not to disable power management everywhere. Instead exempt only apps that genuinely need reliable background activity—such as messaging navigation, alarms wearables, VPNs, or backup tools while leaving normal optimization enabled for everything else.

Instead exempt only apps that genuinely need reliable background activity—such as messaging navigation, alarms wearables, VPNs, or backup tools while leaving normal optimization enabled for everything else.
Why Android Battery Optimization Can Stop Background Activity
Android uses power-management systems such as Doze and App Standby to reduce battery use when the phone or an app is idle. These systems can postpone background jobs, network access and synchronization. Android may also remove background processes when memory is needed, so an app disappearing from memory is not always caused by battery optimization alone. That distinction matters. If an app reopens from the beginning misses notifications stops syncing, or disconnects from a wearable background restrictions may be involved. If it repeatedly shuts down while you are actively using it, you may instead be dealing with an app crash, corrupted data or another software problem.
How to Stop Android From Closing Important Apps
Start with the affected app rather than changing battery settings across the entire phone.
- Open Settings > Apps > [App Name] > Battery or App battery usage. Menu names can differ between phones.
- For an app that genuinely needs continuous background access, select Unrestricted, Allow background activity, or the equivalent option available on your device.
- Check whether Battery Saver or Power Saving is enabled. Android says Battery Saver can limit background activity, network connections and certain app features.
- On Samsung Galaxy phones, go to Settings > Battery > Background usage limits. Check Sleeping apps, Deep sleeping apps, and Never sleeping apps.
- Verify notification permissions, background data access, and other permissions the app needs. Changing battery settings will not fix notifications or syncing if those permissions are blocked separately.
Use Unrestricted Battery Access Only When Needed
Setting every app to unrestricted can increase background activity and battery drain. Only give extra battery access to apps that genuinely need to work while your screen is off. Messaging, navigation, alarms, security, wearables, VPNs and cloud-backup apps may benefit from unrestricted access. Games, shopping apps and other apps you use manually usually do not need it.

Final Takeaway
If apps keep closing on Android, change Android battery optimization settings only for the affected app first. Then check Battery Saver, manufacturer-specific sleeping-app lists, notifications background data and app updates. This gives important apps more reliable background access without unnecessarily increasing battery use across the entire device.
Frequently asked questions
Yes. Battery optimization can restrict background activity, network access, syncing, and scheduled work. However, Android may also remove an app from memory for other reasons, so battery optimization is not always responsible.
Open the affected app’s battery settings and look for Unrestricted, Allow background activity, or a similar option. Also check Battery Saver and any manufacturer-specific sleeping-app settings.
Only for apps that genuinely need reliable background operation. Disabling optimization unnecessarily can increase battery consumption.
Battery Saver can limit background activity and network access, which may delay syncing, notifications, and other background features.
It generally gives an app more freedom to perform background activity than the normal optimized setting. The trade-off is potentially higher battery consumption.
The phone may be experiencing memory pressure, the app may be crashing, or your device manufacturer may have additional background-management settings. Check app updates and manufacturer-specific battery controls as well.
Deep sleeping apps cannot run in the background and normally operate only after you manually open them.
Yes. Restrictions on background activity or network access can delay some app updates and notifications, particularly when an app is sleeping or the device is conserving power.
It can increase battery usage because the exempted app gets more freedom to work in the background. This is why exemptions should be limited to apps that actually require them.
If the problem mainly happens after leaving an app in the background, power or memory management is more likely. If the app suddenly exits while you are actively using it, investigate app updates, cache or data problems, compatibility issues, and software bugs.
