Android smartphones are powerful, flexible, and packed with features—but most users never unlock their full potential. Many default Android app settings are designed for convenience, not performance, privacy, or battery life. By changing just a few key settings, you can dramatically improve your phone’s speed, security, and overall experience.
In this guide, we’ll explore the best Android app settings you should change today to optimize performance, save battery, protect your privacy, and get the most out of your device. These tips work on almost all Android phones, including Samsung, Xiaomi, Realme, Oppo, Vivo, and Google Pixel devices.
1. Disable Unnecessary App Permissions
Many Android apps request permissions they don’t really need. For example, a flashlight app doesn’t need access to your contacts or location.
Why This Matters
- Improves privacy
- Reduces background activity
- Prevents data misuse
What to Do
- Go to Settings → Privacy → Permission Manager
- Review permissions like:
- Location
- Camera
- Microphone
- Contacts
- Remove access from apps that don’t truly need it
👉 Pro Tip: Set sensitive permissions to “Allow only while using the app.”
2. Turn Off Background App Refresh for Unused Apps
Many apps keep running in the background, consuming battery, RAM, and mobile data—even when you’re not using them.
Benefits
- Better battery life
- Faster phone performance
- Less data usage
How to Change It
- Open Settings → Apps
- Select an app you rarely use
- Tap Battery
- Choose Restricted or Optimize
Repeat this for social media, shopping, or gaming apps you don’t use daily.
3. Limit App Notifications (Notification Spam)
Constant notifications are distracting and drain battery life.
Why You Should Control Notifications
- Reduces interruptions
- Saves battery
- Improves focus
Steps
- Go to Settings → Notifications
- Tap Recently sent
- Disable notifications from:
- Games
- Shopping apps
- Promotional apps
Only keep notifications for essential apps like calls, messages, and banking apps.
4. Change Default App Settings
Android allows you to choose default apps for browsing, messaging, calling, and more.
Why It’s Important
- Better security
- Faster performance
- Improved user experience
What to Check
- Default Browser (use Chrome, Brave, or Firefox)
- Default SMS App
- Default Phone App
Go to Settings → Apps → Default apps and choose trusted, lightweight apps.
5. Disable Auto-Start for Heavy Apps
Some apps automatically start when you turn on your phone, slowing down boot time.
How It Helps
- Faster startup
- Less RAM usage
- Improved battery efficiency
How to Disable
- Go to Settings → Apps → Special app access
- Tap Auto-start (menu name may vary by brand)
- Disable auto-start for unnecessary apps
This feature is especially useful on Xiaomi, Realme, and Vivo phones.
6. Turn Off Location Access for Most Apps
Location access is one of the biggest battery drainers.
Best Practice
Only allow location access to:
- Maps
- Ride-hailing apps
- Weather apps
How to Adjust
- Go to Settings → Location
- Tap App location permissions
- Set most apps to “Don’t allow” or “Allow only while using the app”
7. Disable Personalized Ads (Ad Settings)
Google tracks your app activity to show personalized ads.
Why You Should Change This
- Improves privacy
- Reduces tracking
- Still allows normal app usage
Steps
- Go to Settings → Privacy
- Tap Ads
- Enable Delete advertising ID or Opt out of Ads Personalization
This won’t remove ads completely but limits tracking.
8. Restrict Mobile Data Usage for Apps
Some apps consume mobile data in the background without you knowing.
Why This Matters
- Saves mobile data
- Prevents unexpected data usage
- Improves battery life
How to Do It
- Go to Settings → Network & Internet
- Tap Data usage
- Select an app
- Turn off Background data
This is especially helpful if you’re on a limited data plan.
9. Enable App Hibernation or Deep Sleep
Newer Android versions include app hibernation features that automatically disable unused apps.
Benefits
- Frees up storage
- Improves phone speed
- Saves battery
How to Enable
- Go to Settings → Apps
- Select an unused app
- Enable Pause app activity if unused or Hibernate
Samsung users can use Deep Sleeping Apps for better control.
10. Turn Off In-App Auto Downloads
Some apps automatically download media, updates, or files.
Why You Should Disable It
- Saves storage space
- Reduces data usage
- Prevents clutter
Where to Check
- WhatsApp → Storage & Data
- Play Store → Settings → Network preferences
- Cloud apps like Google Drive
Set downloads to Wi-Fi only whenever possible.
11. Manage App Cache Regularly
Cached data helps apps load faster but can grow too large over time.
When to Clear Cache
- App crashes
- Storage is full
- Phone feels slow
How
- Go to Settings → Apps
- Select an app
- Tap Storage
- Choose Clear Cache
⚠️ Don’t clear App Data unless necessary—it may log you out.
12. Disable Floating Apps & Overlays
Some apps use screen overlays that consume RAM and cause lag.
Examples
- Chat heads
- Floating video players
- Screen overlays
How to Fix
- Go to Settings → Apps → Special app access
- Tap Display over other apps
- Disable for unnecessary apps
13. Update Apps Manually Instead of Automatically
Automatic updates can run at inconvenient times and slow down your phone.
Recommended Setting
- Update apps manually over Wi-Fi
How
- Open Google Play Store
- Go to Settings
- Tap Network preferences
- Set Auto-update apps → Over Wi-Fi only or Don’t auto-update
14. Review App Battery Usage Stats
Android provides detailed battery usage information.
Why This Is Useful
- Identifies battery-hogging apps
- Helps you optimize settings
- Improves daily battery life
Steps
- Go to Settings → Battery
- Tap Battery usage
- Restrict or uninstall apps using excessive power
15. Uninstall Apps You Don’t Use
Unused apps take up storage, run background services, and slow down your device.
Best Practice
- Uninstall apps you haven’t used in 30–60 days
- Replace heavy apps with lighter alternatives
A clean phone is a fast phone.
