Kill the Background Apps That Are Secretly Draining Your Phone

Check what’s eating your battery and RAM

1. Go to Settings > Battery > Battery usage (wording may vary).
2. Tap the top offenders and look for apps with heavy “background” time.
3. For those apps, open Settings > Apps > [App name] > Battery and set it to Restricted (or turn off “Allow background activity”).

Turn off background work you don’t need

To disable background apps Android the clean way:

• Go to Settings > Apps > [App name] > Mobile data & Wi-Fi and disable Background data if you seldom require the app to refresh automatically.
• On Samsung, also check Settings > Battery and device care > Battery > Background usage limits and add rarely used apps to “Sleeping apps.”

Tip: If an app must run (messages, maps, email), don’t restrict it—just focus on games, shopping apps, and social apps that constantly refresh.

Delete the Digital Junk You Didn’t Know Was Piling Up

Storage pressure makes older phones stutter. Your goal here is learning how to free up space on old Android without breaking anything important.

Clear big clutter safely

1. Open Settings > Storage and review categories like Apps, Images, Videos, and “Other.”
2. Use Files by Google (or your phone’s built-in file manager) to delete downloads, duplicate files, and huge videos you no longer need.

Keep photos, lose the bloat

If you want to clear storage on Android without deleting photos, do this:

• Turn on cloud backup (Google Photos or your preferred service).
• Then in Google Photos, use Library > Utilities > Free up space to remove local copies that are already backed up.

Also uninstall apps you haven’t opened in months. A good rule: if you didn’t use it in 60–90 days, you probably won’t miss it.

3. Then update apps: Play Store > Manage apps & device > Updates available > Update all.

If your phone is slow and dying early, the battery is often part of the story. The best Android battery health tips are simple and surprisingly effective.

Use smarter charging

• Try the 20–80% rule most days (avoid living at 100%).

Turn Off These 3 Settings to Instantly Speed Things Up

• Go to Settings > About phone > Software information and tap Build number 7 times (you may need your PIN).
• Then open Settings > System > Developer options.
• Set Window animation scale, Transition animation scale, and Animator duration scale to 0.5x (or Off if you prefer).

This doesn’t “add power,” but it makes the phone feel faster immediately.

• After reboot, sign in with the same Google account and restore from backup when prompted.
