How To Clear Old Cache On Android For Better Speed And Storage
Over time, your Android phone stores temporary files called cache to speed up app loading. But when this cache builds up, it can slow your device down, cause apps to crash, and eat up valuable storage space. Regularly clearing old cache can help your phone run faster, smoother, and with more available memory.
Here’s a quick and easy guide to help you delete old cache on your Android smartphone.
Step 1: Go to Storage Settings
Start by opening the Settings app on your phone. Scroll down and tap on ‘Storage’ or ‘Device Care’, depending on your device model. This section gives you an overview of how your phone’s storage is being used – including apps, media, documents, and cached data.
From here, you’ll be able to identify which areas are taking up the most space and where cache clean-up is needed.
Step 2: Clear App Cache Manually
Once inside the storage settings, tap on ‘Apps’ or ‘Applications’. You’ll now see a list of all installed apps along with the amount of storage each one is using.
To delete cache for individual apps:
- Tap on the app that’s using too much space.
- Then, tap ‘Clear Cache’.
This will delete temporary files without affecting your personal app data like logins or saved preferences.
Repeat this process for other apps with large cache sizes.
Step 3: Use Built-In Device Maintenance Tools
Many Android phones (especially Samsung and Xiaomi models) include a Device Care or Maintenance feature in the settings.
These built-in tools can:
- Analyse storage usage
- Clear cached files from multiple apps at once
- Free up memory automatically
Simply go to Settings > Device Care (or Battery & Device Care) and tap ‘Optimise’ or ‘Clean Now’ to instantly clear unnecessary files.
Step 4: Try Third-Party Cleaner Apps (Optional)
If you want deeper cleaning or automation, third-party cleaning apps from the Google Play Store can help. These apps offer extra features like:
- Junk file removal
- RAM boosting
- App cache sweeping
Popular examples include CCleaner, Files by Google, and SD Maid. Before installing any third-party app, always:
- Read user reviews
- Check app permissions
- Ensure the developer is trustworthy
Some cleaner apps also allow scheduled clean-ups, which makes regular maintenance even easier.
Final Tips:
- Avoid using third-party cache cleaners excessively — some may remove useful data or drain battery.
- Clearing cache is safe but may slow down first-time app loading (until the cache rebuilds).
- Make it a habit to clear cache every few weeks, especially if you’re running out of space or your device feels sluggish.
