Memory Cleanup on Xiaomi Redmi 6A: from simple ways to radical measures

Why Redmi 6A is so fast to fill up memory โ€“ and what to do about it

Owners of Xiaomi Redmi 6A (released in 2018) often face the problem of lack of space, despite modest 16 or 32 GB of internal memory. Even after removing photos and applications, the system persistently signals overflow, it is all about the features of MIUI and hardware limitations of a budget smartphone.

The main memory eaters on Redmi 6A are app cache (especially messengers and social networks), system log files that MIUI creates in the background, and residual data after uninstallation of programs. To this are added updates that take up to 1-2 GB, but are not always deleted correctly after installation, as a result of 16 GB on paper, the user is available only 8-10 GB, and 1-2 GB are actually free.

In this article, 7 proven methods of memory cleaning, from safe (cache removal) to radical (factory reset), taking into account the specifics of Redmi 6A. All methods are tested on current versions of MIUI 12-14 and do not require root rights.

1.Cleaning the app cache is a quick way to free up 500MB-1GB

Cache is a temporary file that apps create to speed up work. On Redmi 6A, they can take up to 30% of the available memory, especially if you are actively using YouTube, Telegram or games. Deleting the cache is safe: apps will simply create it again the next time you run.

How to clean the cache of all applications at once:

  1. Open Settings โ†’ Applications โ†’ Application Management.
  2. Slip on the three dots in the upper right corner and select Sort by size.
  3. Click Clear Cache for each application from the top of the list (those that take >100MB).

To speed up the process, use the built-in MIUI tool:

Settings โ†’ Memory โ†’ Cleaning โ†’ Cash

โœ… Cache of messengers (Telegram, WhatsApp, Viber)

โœ… Cache of browsers (Chrome, Mi Browser)

โœ… Cash games, especially if you havenโ€™t played in a long time)

โŒ Do not delete application data (for example, saved messages in Telegram or bookmarks in Chrome)-->

โš ๏ธ Warning: Once the cache is cleared, YouTube and Google Maps may temporarily run slower, having to re-upload frequently used data.

2. Delete unnecessary files through the โ€œCleanupโ€ in MIUI

MIUI has a built-in Cleanup tool that analyzes memory and suggests removing:

  • ๐Ÿ—‘๏ธ Garbage files (remains after uninstallation of applications, empty folders).
  • ๐Ÿ“ Duplicate photos (if you save photos in both the gallery and Google Photos).
  • ๐ŸŽต Unused. APK (Application installation files left over after updates).
  • ๐Ÿ“„ Large files (>50 MB) that have not been opened for a long time.

To start the scan, go to Settings โ†’ Memory โ†’ Clean โ†’ Scan.

Pay special attention to the Big Files section. Redmi 6A often accumulates:

  • ๐ŸŽฅ High definition video (even 1 minute full) HD weight ~100MB).
  • ๐ŸŽฎ Preservation of games (e.g, PUBG Mobile or Free Fire can take up to 1GB).
  • ๐Ÿ“Š Log files of system applications (names of the type com.miui.*).

๐Ÿ’ก

If MIUI doesnโ€™t find large files but the memory is full, check the DCIM/.thumbnails folder โ€“ it stores thumbnails of photos and videos that can be safely deleted.

Type of fileMedium size on Redmi 6ACan I remove it?
Cash Telegram.300-800 MBYes (but downloaded stickers and media will be lost)
Log files MIUI (/sdcard/MIUI/debug_log)100-500 MBYes (the system will create new ones if necessary)
Residual data after removal of applications50โ€“200 MBYes (use Settings โ†’ Memory โ†’ Cleanup โ†’ Residual files)
Updates MIUI (/sdcard/Downloaded_rom)1-2 GBYes (if the update is already installed)

3. Transfer of applications to SD-card (if supported)

Redmi 6A officially supports memory cards up to 256 GB, but there is a caveat: not all applications can be transferred to SD. However, this will free up 1-3 GB of internal memory.

How to move applications:

  1. Put it in. SD-A card (formatted as a portable storage, not as an internal memory!).
  2. Go to Settings โ†’ Applications โ†’ Application Management.
  3. Select an app (such as Facebook or Spotify) and click Storage โ†’ Change. โ†’ SD-map.

โš ๏ธ Attention: Don't put it on SD System applications (such as Settings or Phone) โ€“ this can cause crashes!

Which applications should be transferred first:

  • ๐Ÿ“š Readers (Moon)+ Reader, FBReader).
  • ๐ŸŽฎ Games with big resources (Clash of Clans, Brawl Stars).
  • ๐Ÿ“บ Video players (VLC, MX Player).

4. Cleaning system application data (without root)

Even if you haven't installed many programs, MIUI system applications can take up gigabytes of memory.

  • ๐Ÿ“ฑ Mi Video caches the videos viewed.
  • ๐ŸŽต Mi Music keeps the album covers.
  • ๐Ÿ“ก Security (Security) stores scan logs.
  • ๐Ÿ“Š Analytics collects data on smartphone usage.

  2. Find a system app (such as Mi Video) and tap it.
  3. Select Warehouse โ†’ Clear the data (not the cache, but the data!).

What System Applications Should Not Be Cleaned
Cleaning up the following applications data may cause crashes: - Settings (com.android.settings) - Phone (com.android.dialer) - Google Services Framework (com.google.android.gsf) - MIUI System UI (com.miui.system) If after cleaning one of these applications stops working, reset (see section 7).

After cleaning the system application data:

  • โœ… Free 200-500 MB of memory.
  • โœ… The number of background processes will decrease.
  • โš ๏ธ Some settings will reset (for example, in Mi Video will disappear selected videos).

5. Removal of MIUI updates and old firmware

MIUI It automatically downloads updates in the background, but doesn't always delete installation files after installation. 6A They can borrow up to 2 GB in a folder /sdcard/Downloaded_rom.

  2. Open the folder. Downloaded_rom storage.
  3. Delete all files with the.zip extension (e.g, miui_HM6AGlobal_V12.0.1.0.QCBMIXM_...).

If you donโ€™t have a folder, check /sdcard/MIUI/backup/AllBackup (reserve backups before updates).

You can also remove updates via ADB (if you have experience with command line):

adb shell pm uninstall -k --user 0 com.xiaomi.market


adb shell pm clear com.android.updater

These commands will remove the cache of MIUI Updates and Mi App Store.

๐Ÿ’ก

Do not delete update files if you plan to roll back to a previous version of MIUI. These may be needed to restore the system.

6. Disabling unnecessary system services

MIUI contains many background services that consume memory and resources, some of which can be turned off without compromising the smartphone.

  • ๐Ÿ“ก Mi Cloud Sync (if you donโ€™t use Xiaomi Cloud).
  • ๐Ÿ“Š Usage & Diagnostics (sending statistics to Xiaomi).

โš ๏ธ Note: Do not disable services called com.android. or com.qualcomm. โ€“ this can lead to unstable phone operation.

Effects of disconnecting services:

  • โœ… 100-300 MB of memory is released.
  • โœ… Battery consumption is reduced.
  • โœ… System speeds up (less background processes).

7.Reset to factory settings is the last chance

If all previous methods failed and the Redmi 6A has less than 500MB of free memory, you'll have to do a hard reset, which is a radical way to delete all data, including:

  • ๐Ÿ“ฑ Applications and their settings.
  • ๐Ÿ“ท Photos, videos and music.
  • ๐Ÿ“ž Contacts (if not synced with Google).
