How to completely clean the β€œOther” section on Xiaomi Redmi 9 without risk to the system

The β€œOther” section in Xiaomi Redmi 9 memory is a real headache for many users. It can take up 10 to 30 GB of precious space, and the system insists that it β€œcannot be removed.” In fact, it is not: some of these files can be safely cleaned, and some even transferred to a memory card. In this article, we will discuss all the ways, including hidden MIUI functions, which are not shown in standard settings.

The problem is that under the category β€œOther” Xiaomi hides several types of data: cache system applications, temporary update files, error logs, remnants of deleted programs and even hidden backups that create MIUI Cloud without your knowledge. Just clicking β€œClean” in the memory settings will not work here – you need to act point-by-point. We tested all methods on Redmi 9 with MIUI 12-14 and selected only those that actually vacate space.

Why The Other Takes So Much Space on Redmi 9

On the Redmi 9, which is 64 or 128GB of storage, the Other section often grows to illogical sizes, for three key reasons:

  • πŸ“± Systemic debris MIUI: Temporary update files (.zip and.apk), Google Play Services cache and MIUI System Launcher that does not automatically clean.
  • πŸ—‘οΈ Remnants of Remote Applications: Even after uninstallation, programs leave files in folders /data/data/ and /Android/obb/.
  • πŸ”„ Hidden backups: MIUI automatically creates backup settings, SMS and call logs in a folder MIUI/backup/, weighing 5–7 GB.

Another invisible memory eater is the dalvik-cache files, which take up to 1-2 GB and are recreated after rebooting, but can be forcibly cleaned through Recovery, which is more detailed in the Deep Cleanup section.

folder /cache/ and /data/ota_package/ They store uploaded firmware to remove it:

1. Open the file manager (e.g. Files by Google).


2. Go to Internal Memory β†’ Cache and delete all the contents.




3 Go back and find the ota_package folder β€” delete the files with the.zip extension.

Do not delete the cache folders and ota_package The system will restore them automatically if necessary.

πŸ’‘

If the app starts to slow down after cleaning the cache, restart the phone. MIUI reassembles the cache in 5-10 minutes.

Deep Cleaning with Recovery Mode

If standard methods don't work, use Recovery mode, which is safer than root, but requires caution:

  1. Enter Recovery Turn off Redmi 9, then press the Power button + Volume up until the MI logo appears. From the menu, select the language (if you have a choice) and go to Wipe & Reset.
  2. Select Wipe Cache (not to be confused with Wipe Data!) This will delete temporary files of the Android virtual machine, freeing up 1-2 GB.
  3. Resetting settings MIUI If the Other takes up more than 15GB, try Wipe All Data.Caution: This will delete all user data, but return the memory to its original state. If you press the buttons, the phone vibrates but does not load into Recovery, then the boot partition is damaged.

Hidden folders and files that can be deleted

How do you check which files are occupied by the β€œOther”?
Use the Storage Analyzer or Files by Google app: Open the app and select Memory Analysis. Click on the Other section to show the largest files. Sort by size and remove the unnecessary (such as old.apk or.log files). For advanced analysis, connect your phone to your PC and use WinDirStat or TreeSize.
