- Remove old downloads
- Transfer files to cloud storage
- Clear WhatsApp and media folders
Step 6: Disable Background Apps
Background apps consume RAM and CPU power.
How to Close Background Apps
- Tap Recent Apps button
- Close unused apps
- Use built-in memory cleaner if available
Step 7: Disable or Reduce Animations
Animations make Android visually appealing but slow older devices.
How to Reduce Animations
- Enable Developer Options
- Open Developer Settings
- Reduce:
- Window animation scale
- Transition animation scale
- Animator duration scale
Set values to 0.5x or Off.
Step 8: Check Internet Connection
Many apps rely heavily on internet speed.
Internet Impact on App Speed
| Internet Quality | App Performance |
|---|---|
| Strong WiFi | Fast loading |
| Average Mobile Data | Moderate speed |
| Weak Signal | App delays and errors |
Step 9: Disable Battery Optimization for Important Apps
Battery optimization restricts background activity.
How to Disable Battery Optimization
- Open Settings
- Tap Battery
- Tap Battery Optimization
- Select Important Apps
- Disable optimization
Step 10: Update Android Operating System
System updates improve app compatibility.
Why OS Updates Improve Speed
- Fix system bugs
- Improve resource management
- Enhance security performance
Step 11: Remove Widgets and Live Wallpapers
Widgets and animated wallpapers consume memory continuously.
Performance Improvement Benefits
- Reduces RAM usage
- Improves battery life
- Enhances app responsiveness
Step 12: Scan for Malware or Harmful Apps
Malicious apps often run hidden background processes.
Signs of Malware Slowing Apps
- Unexpected ads
- Rapid battery drain
- Apps opening automatically
- Phone overheating
How to Scan for Malware
- Use Google Play Protect
- Install trusted antivirus apps
Step 13: Use Lite Versions of Apps
Lite apps use fewer resources and load faster.
Popular Lite Apps
- Facebook Lite
- Messenger Lite
- YouTube Go
- Twitter Lite
Step 14: Clear System Cache Partition
System cache contains temporary files that may slow apps.
⚠ Steps vary by manufacturer but usually include:
- Turn off device
- Enter recovery mode
- Select Clear Cache Partition
- Restart device
Step 15: Limit Background Processes (Advanced)
Reducing background process limits improves RAM availability.
How to Limit Background Processes
- Open Developer Options
- Tap Background Process Limit
- Select 2–4 processes
