How to Delete Junk Files and Clear Cache on Xiaomi Safely

Clearing cache and junk files on Xiaomi is safe, free, and takes under 2 minutes. Here's what to delete — and what to leave alone.

What Is Junk / Cache?

• App cache: Temporary files apps create to load faster (safe to delete)
• Residual files: Leftover files from uninstalled apps (safe to delete)
• APK installer files: Leftover installation packages (safe to delete)
• Log files: System and app logs (safe to delete)
• Thumbnail cache: Previews for photos/videos (safe to delete — regenerates automatically)

Method 1: Phone Manager (Security App) — Recommended

1. Open the Security (Phone Manager) app
2. Tap "Clean" or "Cleaner"
3. Tap "Scan" — HyperOS finds junk across all categories
4. Review what was found (you can expand each category)
5. Tap "Clean Up" to delete

This is the safest method — the built-in cleaner knows what's system-critical and won't delete anything important.

Method 2: Clear All App Cache at Once

Settings → Additional Settings → Storage → "Cached Data" → tap to clear all. Clears cache for every app simultaneously.

Method 3: Clear Cache for Specific Apps

Settings → Apps → Manage Apps → [App] → "Clear Cache"

Best for apps that misbehave or have grown large caches: Chrome, Instagram, TikTok, Maps.

What NOT to Delete

Avoid Third-Party "Cleaner" Apps

Apps like "Phone Cleaner Pro" or "Junk File Cleaner" from unknown developers often do less than the built-in cleaner while displaying intrusive ads. Stick with Xiaomi's Security app for cleaning.
