Experiencing unexpected battery drain on Android devices can be caused by background apps. To manage these apps and alleviate battery issues, users can activate the Adaptive Battery feature by navigating to Settings > Battery > Battery Saver > Adaptive Battery and toggling it on. Regular updates for both the Android system and applications can improve battery performance. Users can check for Android updates in Settings > System > Software updates and for app updates in the Google Play Store under Manage apps & device.
To monitor battery usage, users can go to Settings > Battery > Battery usage to identify which apps consume the most power. For RAM usage, enabling Developer options allows users to see which apps are using memory by going to Settings > About phone > Build number (tap seven times) > System > Developer options > Running services.
Users can stop or uninstall background apps by navigating to Settings > Apps > See all apps, selecting the app, and choosing to force stop or uninstall it. To limit background activity for specific apps, users can enable "Pause app activity if unused" or toggle off "Allow background usage" in the app's battery usage settings. Some manufacturers offer built-in options for managing background apps, and third-party apps like Greenify can also help. Common battery-draining apps include social media and streaming services.
