This process removes temporary system files — not your personal data.
It is safe, quick, and recommended after major updates.
What Is Cache Partition?
Samsung devices store temporary system files in a separate partition.
After updates, old cache files can conflict with new system files.
This may cause:
- Battery drain
- Overheating
- Random lag
- Bootloop issues
- App crashes
Clearing cache partition forces the system to rebuild fresh files.
Does This Delete My Data?
No.
It does NOT delete:
- Photos
- Apps
- Messages
- Contacts
It only clears temporary system cache.
Step-by-Step: How to Clear Cache Partition
- Turn off your Samsung phone completely.
- Press and hold Volume Up + Power button together.
- Release when the Samsung logo appears.
- You’ll enter Recovery Mode.
- Use Volume buttons to navigate to “Wipe Cache Partition.”
- Press Power to select it.
- Confirm “Yes.”
- After it finishes, choose “Reboot system now.”
The first boot may take slightly longer than usual.
When Should You Do This?
- After major One UI updates
- If battery drain continues for more than 3 days
- If the phone overheats unexpectedly
- If apps crash after update
Final Thoughts
Clearing cache partition is one of the safest and most effective troubleshooting steps for Samsung Galaxy phones.
If you’re experiencing battery drain after update, combine this method with:
- Disabling RAM Plus
- Limiting background apps
- Adjusting Galaxy AI settings
