Background apps that continuously fetch location data, poll advertising networks, and refresh social feeds drain battery life and cause phone sluggishness.
While Android handles RAM management automatically, poorly coded third-party apps can keep your CPU awake. Here is how to take complete control of background processes on Android.
Method 1: Put Apps into "Restricted" Battery Mode
Android allows you to customize battery usage permissions on a per-app basis.
- Open Settings on your phone.
- Tap Apps (or App Management).
- Select the app that is draining battery (e.g., Facebook, TikTok, or shopping apps).
- Tap App battery usage (or Battery).
- Choose Restricted (or Optimized):
- Restricted: The app is strictly forbidden from running in the background when not actively open on screen.
- Unrestricted: Allows background activity (use only for critical alarms or fitness trackers).
Method 2: Put Apps to Deep Sleep (Samsung Galaxy)
Samsung One UI includes an industry-leading feature called Deep Sleeping Apps:
- Open Settings and tap Device Care > Battery.
- Tap Background usage limits.
- Toggle Put unused apps to sleep to ON.
- Tap Deep sleeping apps and tap the + (plus) icon.
- Select all apps you only want active when you open them. Deep sleeping apps never run in background and won't send unprompted notifications.
Method 3: Restrict Background Mobile Data
If you want to stop background apps from consuming cellular data:
- In Settings > Apps, select the target app.
- Tap Mobile data & Wi-Fi.
- Switch the Background data toggle to OFF.
- The app will now only access the internet when you are actively using it.
Method 4: Limit Background Processes in Developer Options
For power users who want system-wide enforcement:
- Go to Settings > About phone and tap Build number 7 times to unlock Developer Options.
- Go to Settings > System > Developer options.
- Scroll to the Apps section and tap Background process limit.
- Select At most 2 processes or Standard limit.
Warning: Do not choose "No background processes" as this will prevent incoming messaging notifications and music playback while your screen is off.
