Cache Cleanup on Xiaomi Redmi 8 Pro: A Complete Guide to Accelerating Your Smartphone

Xiaomi Redmi 8 Pro is a popular smartphone with a balance of performance and price, but even it eventually begins to slow down. One of the main reasons is crowded cache. In this article, we will discuss how to properly clean the cache on your device without deleting important data, and return it to the performance of 2020 (when the model was first released).

Cache is a temporary file that creates applications and a system to speed things up. Over time, it accumulates, taking up up to 3-5 GB of memory, and instead of helping, it gets in the way. On the Redmi 8 Pro with its 64/128 GB drive, this is especially noticeable. We'll look at everything from manual cleaning through settings to hidden MIUI features and third-party utilities.

Why you should clean the cache on Xiaomi Redmi 8 Pro

The Redmi 8 Pro’s cache has two functions: it speeds up the loading of frequently used data and saves traffic, but when it’s larger than 1-1.5 GB, problems begin:

  • 🐒 Slowing the interface – lags when scrolling the menu, delays when opening applications.
  • πŸ”‹ Fast battery discharge – the system spends resources on processing unnecessary temporary files.
  • πŸ“± Overheating of the device - the processor is loaded with unnecessary operations with the cache.
  • 🚫 Application errors – conflicts between outdated cache files and new versions of programs.

On the Redmi 8 Pro with its Snapdragon 665 processor and 4GB of RAM, cache is particularly pronounced. For example, the Google Play Store may give a 924 error when updating apps, and WhatsApp can hang when sending media files. Regular cleaning (once every 1-2 months) solves these problems.

  2. Go to the Cleanup tab.
  3. Click Scan and wait for the analysis to be completed.

  • πŸ”„ Regular cleaning – you can set up automatic scanning on schedule.

On Redmi 8 Pro, the Security utility removes up to 1.2 GB of cache in a single pass, whereas manually clearing through Settings usually finds no more than 800 MB. This is because the system application has access to hidden /data/local/tmp and /cache folders that don’t appear in the standard file manager.

πŸ’‘

After cleaning through the "Security" reboot the phone - this will allow the system to correctly recalculate the free space and avoid errors in the next scan.

Method 3: Cleaning the cache with Recovery Mode

If your smartphone is slowing down or not responding to commands, you can use Recovery Mode, which removes all system cache, including update files, but does not affect user data.

The following is a step-by-step instruction for Redmi 8 Pro:

  2. Press the Power + Volume buttons up at the same time and hold for 10-15 seconds until the MI logo appears.
  3. In the Recovery menu, select Wipe & Reset (use volume buttons for navigation, power button for confirmation).
  4. Select Wipe Cache and confirm the action.
  5. Once completed, press Reboot to reboot.

⚠️ Warning: Don't confuse Wipe Cache with Wipe Data! The second option will completely reset your phone to factory settings, deleting all your files, photos and apps.

This method is useful if:

  • πŸ”„ Phone stuck on loading (Endless Xiaomi logo).
  • πŸ“± After updating MIUI There are interface glitches.
  • 🚫 Applications are mass-flying with the error "The application is stopped".
What to do if Recovery Mode does not open?
If after you pinch Power + Volume up the phone just turns on in normal mode, try: 1. Connect the charger (sometimes Recovery requires power from the network). 2. Use the combination Power + Volume up + Volume down (on some versions of MIUI). 3. Install official Recovery via Fastboot (requires a PC and a USB cable).

Method 4: Using a File Manager

For advanced users, it is possible to manually delete the cache through the root file manager or standard Explorer from Xiaomi, which allows you to pinpoint delete unnecessary files, but requires caution.

How to clean the cache manually:

  1. Open Explorer (or install Root Explorer if you have root access).
  2. Go to /data/data/ – this is where all the app cache files are stored.
  3. Find a folder with the name of the application package (for example, com.android.chrome for Chrome).
  4. Delete the contents of the cache folder (don’t touch the other folders!).

List of key cache folders on Redmi 8 Pro:

  • πŸ“ /data/dalvik-cache β€” Dalvik virtual machine cache (can only be deleted via Recovery).
  • πŸ“ /cache β€” System cache (cleaned through Recovery or ADB).
  • πŸ“ /data/local/tmp β€” installer-file.
  • πŸ“ /sdcard/Android/data/ β€” cache of applications on the memory card.

πŸ’‘

Manually clearing cache through the file manager is 20-30% more efficient than system tools, but requires care. Deleting the wrong files can lead to the collapse of applications!

Method 5: Third-party utilities for deep cleaning

If standard methods don’t work, third-party apps can be used, offering advanced features like cleaning Dalvik cache, removing duplicates, and optimizing autoboots.
