Memory Cleanup on Xiaomi Redmi 8: a complete guide with hidden MIUI chips

Xiaomi Redmi 8 is one of the most popular budget smartphones with 4/64 GB of memory, but even this amount is not enough over time. MIUI actively caches data, applications accumulate unnecessary files, and users often do not know how to properly free up space without harming the phone. In this article, 7 proven ways to clean up memory, including hidden MIUI features that are not described in the official documentation.

The Redmi 8 features hybrid memory: part of the built-in drive is given to system needs, and the user is available about 50-55 GB of the declared 64 GB. At the same time, MIUI aggressively reserves space for updates and cache, which creates the illusion of lack of memory even with free gigabytes.

1. Built-in cleaning MIUI: What is missing and what is missing

The most obvious way is to use the built-in Security β†’ Cleanup tool. It removes:

  • πŸ—‘οΈ Application cache (temporary files that can be restored on the next run)
  • πŸ“ Unnecessary APK (residues of established programmes)
  • πŸ“₯ Downloads (files from the Download folder, older than 30 days)
  • πŸ—‚οΈ Duplicate files (only in the MIUI 13+)

However, this method has critical limitations:

  • ❌ Does not clear the cache of system applications (e.g. com.miui.gallery or com.android.providers.media)
  • ❌ Does not delete residual data after uninstallation of programs (folders) /Android/data/ and /Android/obb/)
  • ❌ Ignores hidden files from Xiaomi Cloud and Mi Account

To start deep cleaning through standard means:

  1. Open Settings β†’ Applications β†’ Application Management.
  2. Slip on the three dots in the upper right corner and select Sort by size.
  3. View the list and manually clear the cache for applications from 100MB and above.

⚠️ Note: Do not clear the cache for Google Play Services and Services Framework – this may disrupt Google services and lead to sync errors.

πŸ“Š How often do you clean your memory on your smartphone?
Once a week.
Once a month
Only when the place ends.
Never clean.

2 Manual removal of junk files: hidden folders and secure paths

Even after using the built-in cleaning, Redmi 8 still has gigabytes of invisible garbage, and here are 5 key folders that can be manually cleaned without risk to the system:

Folder/pathWhat it keeps.Is it safe to remove?Potential savings
/storage/emulated/0/Android/data/Residual data of remote applicationsβœ… Yes (only folders of non-existent programs)500MB to 3GB
/storage/emulated/0/Android/obb/Additional game files (cache, textures)βœ… Yes (games will be reloaded if necessary)From 1 GB to 10 GB
/storage/emulated/0/MIUI/backup/AllBackup/Backup copies of MIUI (if not used)βœ… Yes.Up to 5GB
/storage/emulated/0/.thumbnails/Miniatures for gallery (automatically restored)βœ… Yes.From 100MB to 1GB
/storage/emulated/0/Download/Downloads from the browser and messengers⚠️ Partially (check the contents)Depends on the user.

To access these folders:

  1. Connect your phone to your PC via USB (File Transfer Mode).
  2. Use Windows Explorer or Total Commander with the "Show Hidden Files" option enabled.
  3. Delete the contents of the folders listed in the table (except Download – check it manually).

⚠️ Note: Do not delete files in folders /system/, /vendor/ or /data/ It's not root-righted, it's going to cause permanent damage to the system and the need to flash it back.

3. Cleaning the cache of system applications: hidden memory reserve

MIUI system applications (e.g. Gallery, Music, Records) accumulate cache that is not cleaned by standard means.

  1. Go to Settings β†’ Applications β†’ Application Management.
  2. Tap it on three points. β†’ Show all the processes.
  3. Find in the list: com.miui.gallery (Gallery) com.miui.player (Music) com.miui.notes (Notes) com.miui.video (Video)

Warehouse β†’ Clear the cache

Pay special attention to the application com.android.providers.media β€” it is responsible for media scanning and can take up to 1-2 GB of cache. its cleaning will not hurt, but after the restart, the phone will re-scan all media files (it will take 5-10 minutes).

Use it to speed up the process. ADB-Team (Developer Mode enabled is required):

adb shell pm clear com.android.providers.media

πŸ’‘

If after cleaning the cache com.android.providers.media gallery for a long time uploads photos, reboot the phone – this will speed up the re-scanning.

4. Transfer of applications to SD-map: circumventing restrictions MIUI

Redmi 8 supports memory cards up to 512 GB, but MIUI blocks most applications from migrating to SD.

Method 1: Through Application Settings (Limited List)

  1. Go to Settings β†’ Applications β†’ Application Management.
  2. Select the application β†’ Warehouse β†’ Change. β†’ SD-map.
  3. Confirm the transfer (only works for a portion of the programs).

How to do the reset correctly:

  1. Create a backup through Settings β†’ Additional β†’ Backup or manually copy files to your PC.
  2. Go to Settings β†’ About the phone β†’ Reset settings.
  3. Choose to erase all data and confirm.
  4. After rebooting, set your phone up as new (don’t restore the backup right away – check the free space first).

Alternative method (via Recovery):

  1. Turn off the phone.
  2. Press Power + Volume up until the Mi logo appears.
  3. Select Wipe Data β†’ Wipe All Data (control – volume and power buttons).

πŸ’‘

Resetting through Recovery removes more debris than a standard reset in the settings, but requires reconfiguration of all system settings.

6.Memory optimization without deleting files: Hidden MIUI chips

If you need to make room but don’t want to delete anything, use the built-in MIUI tools that few people know about:

1. Compression of unused applications

The Light Mode feature (available in MIUI 12+) archives rarely used programs, saving up to 50% of their size:

  1. Go to Settings β†’ Applications β†’ Light mode.
  2. Activate the option and select compression applications.

MIUI 13+ can find repetitive photos and videos.

  1. Open the gallery β†’ Albums β†’ Duplicates.
  2. Select unnecessary copies and click Delete.

3. Disabling automatic download in messengers

WhatsApp, Telegram and Viber download all media files by default.

  • πŸ“² WhatsApp: Settings β†’ Warehouse β†’ Autoboot media β†’ Turn off for mobile data.
  • πŸ“² Telegram: Settings β†’ Data and memory β†’ Autoboot media β†’ Choose Never.

4.Using Xiaomi Cloud Storage

5GB is free in Xiaomi Cloud to transfer photos to:

  1. Open the gallery. β†’ Select the photo β†’ More. β†’ Upload to the cloud.
  2. After downloading, delete local copies (the option to Delete after download).

πŸ’‘

If you use Google Photos, turn on the β€œFree Space” option in the app settings – it will automatically delete local copies of photos that have already been uploaded to the cloud.

7. Advanced methods: root access and custom firmware

If you are willing to take drastic measures, root access will open up additional opportunities:

1. Removal of system applications (bloatware)

With Titanium Backup or Root Explorer, you can remove pre-installed programs that cannot be uninstalled by standard means:

  • πŸ—‘οΈ com.miui.analytics (collection of statistics)
  • πŸ—‘οΈ com.xiaomi.midrop (Mi Drop, if not used)
  • πŸ—‘οΈ com.miui.hybrid (hybrid services) MIUI)

Warning: Removing system applications may disrupt MIUI. Be sure to back up your system through TWRP before doing so.

2. Transfer applications to SD using Link2SD

Link2SD (requires root) allows you to:

  • Transfer any applications to SD-map (including system map).
  • Create links to files, saving space in internal memory.
  • Freeze unnecessary programs.

3. Use of custom firmware

Firmware like LineageOS or Pixel Experience is devoid of pre-installed MIUI debris and takes up 2-3 GB less space.

  • Unlocked bootloader (bootloader).
  • Installed TWRP Recovery.
  • Experience with fastboot and ADB.

⚠️ Attention: Inept actions with custom firmware can lead to a "brick" of the phone (completely inoperable). On Redmi 8 it is especially dangerous to use firmware for other models (for example, Redmi). 8A).

FAQ: Frequent questions about memory cleaning on Redmi 8

Why does the memory fill up quickly after cleaning?
This is due to two factors: System process cache: MIUI actively caches data to speed up work. Cleanup gives a temporary effect. Application background activity: Messengers, social networks and games are constantly downloading updates and media files. Solution: Turn off auto-update applications in Google Play and limit background activity in Settings β†’ Battery β†’ Power Management.
Can I clean the DCIM folder without losing a photo?
The DCIM folder stores photos and videos taken by the camera, and you can only delete the contents after you back up, but inside the DCIM, there's a hidden folder called.thumbnails, which you can clean without risk (these are thumbnails that the gallery will restore automatically).
How do I know which app takes up the most space?
Go to Settings β†’ Applications β†’ App management, tap three dots β†’ Size sorting. The system will show apps from the heaviest to the lightest. Pay attention to: com.android.chrome (browser cache) com.facebook.katana (Facebook) com.whatsapp (messaging media files)
What if the phone says "Not enough memory" but there is a place?
This is a MIUI error related to system memory reservations. Solutions: Reboot your phone. Clear the cache of com.android.providers.media (see section 3). Delete the latest updates for Google Play Services (Settings β†’ Apps β†’ Google Play Services β†’ Three dots β†’ Remove updates).
Can I increase memory on Redmi 8 with a flash drive?
Physically, no. Redmi 8 does not support Adoptable Storage technology. SD-maps that were in older versions of Android, but you can: Move individual apps to the old Android versions. SD (See section 4. Store media files on a memory card. Use SD as a portable storage device (but not as an extension of internal memory).
