Cleaning memory on Xiaomi Redmi 6A: a complete guide for Android

Has Xiaomi Redmi 6A began to slow down, applications are constantly closing, and the memory is full to capacity? This is a typical problem for budget smartphones, where the system and pre-installed applications take up the lion's share of space. Even after deleting photos and instant messengers, free space melts like snow under the sun - this is due to 16 GB of internal memory, where the system and pre-installed applications take up the lion's share of space. Even after deleting photos and instant messengers, free space melts like snow under the sun - this is due to application cachejunk files and background processes.

In this article you will find unique memory cleaning methods specifically for the Redmi 6A, taking into account the features of its firmware MIUI and hardware limitations. We will figure out how to free up space without losing important data, which system folders can be cleaned manually, and why standard advice like “uninstall unnecessary applications” only works halfway here. And you will also learn how to prevent the memory from quickly filling up in the future - with this smartphone, proactivity is much more important than reactive cleaning.

Why does the memory on the Redmi 6A run out so quickly?

The main problem Redmi 6A is a combination modest 16 GB of memory (of which ~10-12 GB are available to the user) and aggressive policy MIUI to create backups and cache. Even after a complete reset, the system takes up to 6-7 GB, and each installed messenger or social network adds hundreds of megabytes of “invisible” garbage.

Here are the key memory "eaters" on this device:

• 📱 MIUI system cache: the firmware creates duplicate applets, themes and widgets that are not deleted automatically.
• 🗑️ Residual application files: after uninstalling apps, folders are often left in /Android/data/ and /Android/obb/.
• 📸 Gallery thumbnails and metadata: even after deleting photos MIUI Gallery stores their previews and EXIF data.
• 🔄 Logs and system dumps: files .log i .dumpstate can take up to 1-2 GB after failures.

⚠️ Attention: On Redmi 6A versions MIUI below 12.5 there is no built-in “Memory Analysis” - this function was added later. Do not confuse it with the “Storage” section in the settings, which shows only general data.

Another feature is partition /data quickly fragments. Due to cheap eMMC memory (and not UFS, as in flagships), the recording speed drops by 30-40% even when it is 80% full. Therefore, cleaning not only frees up space, but also restores performance.

Method 1: Clearing the application cache manually

Let's start with the safest method - deleting temporary files (cache). On Redmi 6A this can be done both for individual applications and globally for the entire system. Important: the cache does not contain personal data, so clearing it will not lead to the loss of photos or messages.

Instructions for clearing the cache for a specific application:

1. Open Settings → Applications → Management applications.
2. Select the desired application (for example, Facebook or YouTube).
3. Click Storage → Clear cache.
4. For complete clearing, click Space management → Clear all data (⚠️ this will delete settings and accounts in the application!).

For mass clearing the cache of all applications:

1. Go to Settings → Storage → Cache data.
2. Confirm clearing (may take 1-2 minutes).

Delete messenger cache (Telegram, WhatsApp)|Clear Google Play Services data|Delete browser cache (Chrome, MIUI Browser)|Clear map cache (Google Maps, Yandex.Maps)-->

After clearing the cache, some applications may take longer to load when first launched - this is normal. But you will free up from 500 MB to 1.5 GB (depending on the number of installed apps).

⚠️ Attention: Do not clear the cache of system applications like MIUI System or Android System —this may cause the interface to malfunction.

Method 2: Removing junk files through MIUI Security

MIUI Security (or "Security" in Russian-language firmware) is a built-in tool for system optimization. It can find and delete unnecessary files that are not visible in the standard storage manager. Redmi 6A this is one of the most effective solutions.

How to use MIUI Security for cleaning:

1. Open the application Security (icon with a shield).
2. Go to the tab Cleaning (or Deep Clean in the English version).
3. Click Scan and wait for completion (may take up to 3-5 minutes).
4. Tick all categories (Residual files, Cache, Large files) and click Clear.

What exactly deletes MIUI Security:

• 🧹 Residual APK files: uninstalled packages after updating applications.
• 🗃️ Empty folders: directories from uninstalled apps.
• 📄 Temporary files: downloads that have not been opened for more than 30 days.
• 🔍 Log files: error logs and crash reports.

After cleaning, restart the phone - this will help the system re-index the freed space. On average, this method frees up from 800 MB to 2 GB, but the result depends on how long ago you last cleaned the device.

Method 3: Manually cleaning folders through the file manager

For experienced users, there is a more radical method - manual cleaning of system foldersThis allows you to delete files that are not visible by standard means, but requires caution: an error can lead to a system crash.

Which folders can be cleaned manually (use MI File Manager or Solid Explorer):

How to clear these folders:

1. Open MI File Manager and turn on the display of hidden files (Settings → Show hidden files).
2. Go to the desired folder (for example, /Android/obb/).
3. Select unnecessary files and click Delete.
4. For folders like /DCIM/.thumbnails just delete all content - it will be restored the next time you view galleries.

⚠️ Attention: Do not delete files in folders /system/, /vendor/ or /data/app/ - this will lead to system crash. Also, do not touch files with the extension .odex or .vdex.

adb shell
su
rm -rf /path/to/file

Method 4: Transferring data to the card memory

Redmi 6A supports cards microSD up to 256 GB, but by default applications are installed in the internal memory. Fortunately, some of the data can be transferred to an external drive, freeing up precious megabytes.

What can be transferred to a memory card:

• 📷 Photos and videos: through Gallery or a file manager.
• 🎵 Music and podcasts: in the player settings (for example, MIUI Music or Spotify).
• 📱 Data of some applications: only if the developer has provided this option (checked in Settings → Applications → Storage → Edit).
• 📁 Downloads and documents: change the default save path in the browser settings or office applications.

How to transfer applications to a memory card (if supported):

1. Open Settings → Applications → Manage applications.
2. Select an application (for example, Maps or Netflix).
3. Click Storage → Edit → Memory card.
4. Confirm the transfer (may take a few minutes).

Method limitations:

• ❌ Not all applications support transfer (especially system and games).
• ❌ On the card microSD applications run slower (due to eMMC vs UHS-I limitations).
• ❌ After removing the card, the transferred apps will stop working.

Method 5: Disabling and deleting system applications

MIUI famous for the abundance of pre-installed applications, many of which duplicate Google functions or are simply useless. They cannot be removed using standard means, but can be Redmi 6A they cannot be removed using standard means, but they can be disable or uninstalled via ADB.

• 💼 Mi Pay (com.mipay.wallet) - does not work in Russia and many countries.
• 📊 Analytics (com.miui.analytics) - collects data for Xiaomi (can be disabled without consequences).

How to disable system applications:

1. Open Settings → Applications → Manage applications.
2. Click on the three dots in the upper right corner and select Show all processes.
3. Find the application you need (for example, Mi Browser).
4. Click Disable (or Uninstall updatesif the button is active).

For complete removal required ADB:

adb shell
pm uninstall -k --user 0 com.miui.player

⚠️ Warning: Do not delete applications with names com.android., com.qualcomm. or com.miui.home —this will lead to system inoperability.

Method 6: Reset to factory settings (last chance)
