How to Clear the System Cache Partition on Xiaomi / Redmi Phone
Clearing the cache partition fixes sluggishness, boot loops, and glitches after system updates — without deleting your personal data, apps, or settings.
What Is the Cache Partition?
The cache partition stores temporary system files used to speed up the OS. Over time (especially after updates), outdated cached files can cause conflicts. Wiping it is safe and clears only these temporary files.
Step-by-Step: Enter Recovery Mode
- Power off the phone completely.
- Hold Volume Up + Power simultaneously.
- Release buttons when the Xiaomi / Mi logo appears.
- You'll enter MIUI Recovery (text-based menu on most models).
On some newer HyperOS models: hold Volume Down + Power to access the boot menu, then navigate to Recovery.
Step-by-Step: Wipe Cache Partition
In the Recovery menu:
1. Use Volume buttons to navigate, Power button to select.
2. Select "Wipe cache" or "Wipe cache partition".
3. Confirm → the process takes 30–60 seconds.
4. Select "Reboot to system" when done.
When to Clear Cache Partition
| Symptom | Likely Fix |
|---|---|
| Phone slow after system update | ✅ Clear cache partition |
| Apps crashing after update | ✅ Clear cache partition |
| Boot loop after update | ✅ Clear cache partition |
| Random reboots | ✅ Worth trying |
| App-specific issue | ❌ Clear individual app cache instead |
What Is NOT Deleted
- ✅ Photos, videos, music
- ✅ Installed apps and app data
- ✅ Contacts, messages, accounts
- ✅ Downloaded files
Pro Tips
- Clearing the cache partition is completely reversible — the system rebuilds the cache automatically.
- If Recovery only shows English options, use Volume Up at boot instead of Volume Down.
- For stubborn issues that cache wipe doesn't fix, consider a full factory reset — but back up data first.
