No matter how expensive or popular your Android phone is, it can start slowing down after some months of use. Apps become heavier, storage fills up, background activities increase, and the device becomes slower. The good news is that you do NOT need to buy a new phone immediately. With the right steps, you can make your phone run faster, smoother, and more efficiently — even if it is an older model.
This guide explains practical and beginner-friendly ways to speed up your Android device in 2025.
Let’s begin!
Why Do Android Phones Become Slow?
Before we fix the problem, it’s important to understand what causes your phone to lag:
✔ Too many apps running in the background
✔ Low storage space
✔ Old system software
✔ Cached data and junk files
✔ Heavy apps like TikTok, Facebook, or games
✔ Too many animations
✔ Weak battery or overheating
✔ Using slow memory cards
Now let’s fix all of these step-by-step.
1. Restart Your Phone Regularly
This is the simplest but most effective method.
Restarting your phone:
- Clears RAM
- Stops background apps
- Refreshes system processes
- Removes minor bugs
If your phone is slow, restart it once every 2–3 days.
2. Clear App Cache (Not App Data)
Over time, apps store cached data which can reach several GBs and slow down the device.
How to clear cache:
- Go to Settings
- Tap Apps
- Select the app
- Tap Storage
- Tap Clear Cache
Clearing cache does NOT delete your account or information — it only removes temporary files.
Apps that build the most cache:
- TikTok
- Chrome
- Facebook Lite
- Snapchat
Clear their cache weekly.
3. Uninstall Apps You Don’t Use
Most people have 30–50 apps they never use.
Unused apps:
❌ Eat up RAM
❌ Slow down the phone
❌ Reduce battery life
❌ Take storage space
Delete apps you don’t need:
- Go to Settings → Apps
- Sort by Storage Size
- Remove unwanted apps
If you don’t use an app at least once a month, uninstall it.
4. Disable Pre-Installed Bloatware
Some phones (especially Tecno, Infinix, Xiaomi) come with unwanted system apps.
You can’t uninstall them, but you can disable them.
How to disable bloatware:
- Settings → Apps
- Select the app
- Tap Disable
Common bloatware examples:
- Palmstore
- AHA Games
- XShare
- HiOS apps
- Freezer
- Infinix/Itel system ads
Disabling them will make your phone faster.
5. Free Up Storage Space (Keep at least 20% free)
When your phone storage is full, the device becomes very slow.
Keep at least 5GB – 10GB free.
How to free storage:
✔ Delete old screenshots
✔ Delete WhatsApp media
✔ Remove duplicates
✔ Move photos/videos to Google Photos
✔ Delete heavy movies
✔ Remove old APK files
WhatsApp tip:
WhatsApp alone can take 5–20GB.
Go to:
WhatsApp → Settings → Storage & Data → Manage storage
Delete unnecessary large files.
6. Update Your Apps and System
App and system updates fix bugs and improve performance.
To update apps:
Open Google Play Store → Manage apps → Update all
To update system:
Settings → Software Update → Check for updates
New updates make the device run smoother.
7. Reduce Animations for Faster Speed
Animations make your phone beautiful but can slow down older devices.
Reduce animations:
- Go to Settings → About Phone
- Tap Build Number 7 times to enable Developer Options
- Go to Developer Options
- Change these to 0.5x or Off
- Window animation scale
- Transition animation scale
- Animator duration scale
This makes your phone feel MUCH faster.
8. Use Lite Versions of Heavy Apps
Heavy apps consume a lot of RAM and data.
Use these lighter alternatives:
| Heavy App | Lite Version |
|---|---|
| Facebook Lite | |
| Messenger | Messenger Lite |
| TikTok | TikTok Lite |
| Chrome | Opera Mini / Firefox Lite |
| YouTube | YouTube Go |
Lite apps load faster and save battery.
9. Turn Off Auto-Sync for Unused Accounts
Auto-sync constantly runs in the background.
Turn off auto-sync for apps you don’t use often.
Go to:
Settings → Accounts → Turn off Auto-Sync
10. Use a Good Antivirus (Optional)
Some budget phones get malware from infected apps or files.
Use any trusted antivirus:
- Avast
- Bitdefender
- Kaspersky
- Google Play Protect (built-in)
Avoid unknown antivirus apps — they slow the phone down more.
11. Remove Live Wallpapers & Heavy Themes
Live wallpapers reduce performance and battery life.
Use simple wallpapers and disable fancy animations.
Heavy launchers like Nova Launcher or GO Launcher also slow the device.
Use:
✔ Default system launcher
✔ Simple wallpaper
12. Use Files by Google to Clean Junk
Google’s “Files by Google” app is one of the best cleaners.
It can remove:
✔ Junk files
✔ Large files
✔ Duplicate files
✔ Temporary data
✔ Unused apps
Install it and clean your phone weekly.
13. Avoid Using Cheap & Slow Memory Cards
Cheap SD cards slow down file loading, camera operations, and app performance.
If you must use one, buy:
✔ Class 10
✔ UHS-I
✔ From trusted brands only
Avoid fake memory cards.
14. Factory Reset (Last Option)
If your phone is extremely slow, the final step is to reset it.
This will make it fast like new.
Before resetting:
✔ Backup your photos
✔ Backup your WhatsApp
✔ Save contacts to Google account
Then go to:
Settings → System → Reset → Factory Reset
Use this only if everything else fails.
Bonus: Tips to Prevent Slow Performance in the Future
✔ Don’t install too many apps
✔ Clear cache weekly
✔ Keep storage above 20%
✔ Restart your phone every 2–3 days
✔ Update your apps
✔ Avoid dirty chargers that damage battery
✔ Don’t overcharge your phone
✔ Avoid overheating
