Memory Cleanup on Xiaomi Redmi 7A: A Complete Guide with Proven Methods

Xiaomi Redmi 7A owners often face a shortage of free space, despite modest 16 or 32 GB of internal memory. the problem is exacerbated by the features of MIUI, which actively caches data and creates duplicate files. Unlike flagship models, the budget Redmi 7A does not support the installation of microSD as the main drive, so cleaning internal memory becomes a critical task.

This article will help you understand how to effectively free up space on the device without resetting to factory settings. We will look at both standard tools MIUI 10/11/12 and hidden features that are not written about in the official instructions. Particular attention will be paid to the removal of system debris, which takes up to 3-5 GB on devices with a long life.

Why is the memory of Redmi 7A being lost?

The main cause of memory overflow is aggressive data caching in MIUI. The system backs up applications, error logs and temporary files that are rarely deleted automatically. On Redmi 7A with a Qualcomm Snapdragon 439 processor and 2GB of RAM, this leads to:

  • 📱 Slowing down the interface when memory is filled by more than 85%
  • 🔄 Unintentional reboots when installing updates
  • 🚫 Inability to install new applications even when "free" 200-300 MB
  • 📸 Errors in saving photos/video in the gallery

The second factor is the storage architecture of eMMC 5.1 used in the Redmi 7A. These memory chips wear out over time when data is overwritten frequently, resulting in fragmentation and loss of performance, and the memory cleaning in this case not only frees up space, but also prolongs the life of the drive.

📊 How often do you clear your memory on your Xiaomi?
Once a week.
Once a month
Only when the place ends.
Never clean.

Preliminary Diagnosis: What Takes Place

Before cleaning, you need to identify the main memory eaters, and on Redmi 7A, you can do this by:

  1. Settings → About phone → Memory (shows general statistics)
  2. Safety → Cleanup (detailed analysis)
  3. Google Files app (shows hidden folders)

Typical memory allocation on a 16GB device:

CategoryOccupied seatCan I remove it?
System files4-5GBPartially.
Cash app.1-3 GBYes.
Media files (photo/video)2-8 GBYes.
APK-file500MB - 2GBJust the de-installation.
Logs and dumps of the system300-800MBYeah (root requires)

Special attention should be paid to /data/log, which accumulates error logs. On Redmi 7A with MIUI 12, it can take up to 1 GB after a year of use. Also check the Download folder - many users forget to delete APK installers and archives from there.

💡

Use Google Play's DiskUsage app to visualize occupied space, and it shows large files and folders as an interactive diagram.

Method 1: Integrated cleaning of MIUI

The safest method is to use the built-in MIUI tools, which do not require superuser rights and rarely cause crashes.

  1. Open Settings → Security
  2. Select the item Clean (icon with broomstick)
  3. Wait for the analysis to be completed (may take 1-2 minutes)
  4. Click Clean up the garbage at the bottom of the screen
  5. Go to the Deep Clean tab to remove the app cache

In this section, it is possible to delete:

  • 🗑️ Unnecessary APK- files (residues after application installation)
  • 📁 Empty folders and temporary files
  • 🔄 Duplicate photos (a feature appeared in MIUI 12)
  • 📥 Unused downloads

Note the Recommendations section here, MIUI suggests removing rarely used apps. On Redmi 7A, this is especially true, as 2GB of RAM is quickly clogged with background processes.

Close all working applications

Connect your phone to charge (the process can take 5-10 minutes)

Disable mobile data (to avoid interrupting the cleanup with incoming calls)

Backup of important files-->

Method 2: Manually cleansing the application cache

System cleaning doesn't always remove the entire cache, and some applications (especially social media and instant messengers) accumulate gigabytes of temporary data.

  1. Go to Settings → Applications → Application Management
  2. Select sort by size (click on the three dots in the upper right corner)
  3. Open the app card and click Clear the cache
  4. To completely delete data, click Clear Data (this will reset the app settings!)

Top-5 "cash monsters" on Redmi 7A:

  1. Facebook up to 1.5GB (especially when watching videos)
  2. Telegram – up to 1 GB (caches media files)
  3. Google Play Services: 300-500MB
  4. MIUI Gallery – 200-400 MB (miniatures of photos)
  5. Chrome – 100-300 MB (web cache)
What happens if you clear the application data?
When you clean the data (not the cache!), the application will return to the “as after installation” state. For instant messengers, this means logging out of the account, for games, loss of progress (if it is not synchronized with the cloud), except for system applications, which can lead to unstable MIUI operation.

To speed up the process, you can use the ADB- command, which clears the cache of all user applications:

adb shell pm trim-caches 1000000000

This command will free up up to 1 GB of space, but requires the phone to be connected to a PC with ADB- drivers installed.

Method 3: Removal of system debris (without root)

Redmi 7A has hidden system folders that can be cleaned without superuser permission.

  1. Install a file manager with access to root folders (such as FX Explorer or Solid Explorer)
  2. Enable the display of hidden files in the manager settings
  3. Go to /data/data and find:
  • 📂 com.android.providers.downloads — download history
  • 📂 com.miui.gallery - gallery cache (miniatures)
  • 📂 com.android.vending - Google Play cache
  • 📂 com.xiaomi.scanner — temporary scanner files

In each of these folders, you can safely delete the contents of the cache and tmp subfolders. Do not touch files with the.db extension - these are application databases.

💡

Never delete files from /system or /vendor folders, as this will cause the device to fail and require flashing.

To delete system logs (files with the.log and.txt extension in /data/log folder) you will need:

  1. Activate Developer Mode (Settings → About Phone → MIUI version – press 7 times)
  2. Enable debugging over USB in Settings → Additional → For developers
  3. Connect your phone to your PC and execute the command: adb shell rm -rf /data/log/*

Method 4: Transfer data to SD- card

Although Redmi 7A does not support Adoptable Storage (using the SD- card as internal memory), some data can be manually transferred:

  • 📸 Photos and videos (via Gallery app)
  • 🎵 Music and podcasts (most players have an export feature)
  • 📄 Documents (via Google Files or MI File Manager)
  • 🎮 Data from certain games (e.g. Minecraft or GTA San Andreas)

The transfer of applications will require:

  1. Install SD- 10 (UHS-I)
  2. Format it as a portable storage (not as an internal memory!)
  3. Use AppMgr III (or Link2SD for root users)
  4. Manually transfer supported applications

Important: Redmi 7A cannot port system applications and most Google services, and some programs (such as WhatsApp) do not work with SD- cards due to Android security limitations.

💡

To speed up the SD- card on the Redmi 7A, turn off the "SD- Card Check" function in the storage settings, which will reduce read/write delays, but increase the risk of data loss when you extract the card without safely shutting down.

Method 5: Reset to factory settings (last chance)

If there is less than 500MB of space left and standard methods don't work, there is Hard Reset. On the Redmi 7A, there are two ways to do this:

Method 1. Through the settings menu:

  1. Settings → About the phone → Resetting settings
  2. Select to erase all data
  3. Confirm the action with a pattern lock or password
  4. Wait for the reboot (takes 3-5 minutes)

Method 2. Through Recovery Mode (if the phone is not turned on):

  1. Turn off the device.
  2. Press Power + Volume Up for 10 Seconds
  3. In the recovery menu, select Wipe Data (Manage volume buttons)
  4. Confirm the action and wait for the completion

After the reset on the Redmi 7A will be available:

  • 📱 11-12 GB of free space (for the 16 GB version)
  • 📱 27-28 GB of free space (for the 32 GB version)
What if the memory is quickly over again?
This indicates hardware degradation of eMMC memory. In this case, only replacing the memory chip in the service center will help, symptoms: persistent write errors, application crashes, inability to save files despite the free space.

⚠️ Warning: Redmi 7A with MIUI 12 may miss the OTA- updates section after reset. To avoid problems with future updates, copy the /cache/recovery folder to your PC before reset.

Method 6: Optimize memory for long-term effects

So that your memory doesn’t get too fast:

  • 🔄 Set up automatic cleaning to Security → Cleanup → Settings (select weekly cleaning)
  • 📸 In Google Photos, enable Free Space (delete local copies after uploading to the cloud)
  • 🎵 In music app settings, limit your cache size to 500MB
  • 📱 Turn off automatic app updates in Google Play
  • 🔍 Check the Download folder regularly for unnecessary files.

For advanced users, it is recommended:

  1. Install Magisk and Universal GMS Doze to limit background activity of Google services
  2. Use Greenify to hibernate unnecessary apps
  3. Disable system applications via ADB: adb shell pm uninstall -k --user 0 com.miui.analytics

On Redmi 7A, pay special attention to disabling Mi Cloud Sync (if not used), which creates local backups that can take up to 2 GB.

FAQ: Frequent questions about memory cleanup

Can I increase the internal memory of Redmi 7A?
No, you can't physically increase the amount of internal memory you have, and the only option is to use the SD- card to store media files, and full-fledged memory expansion (like flagship models) is not supported due to hardware limitations.
Why does memory run out quickly after cleaning?
This is due to the features of the F2FS file system used in Redmi 7A. After cleaning, the system creates new temporary files, and memory fragmentation occurs. Regular cleaning (once every 1-2 weeks) helps maintain free space.
Is it safe to delete the Android/obb folder?
You can delete it, but it will cause some games (especially heavy 3D- projects) to fail, and the files in this folder are additional data for applications. If the game is no longer needed, you can delete the folder with the APK itself.
How to clear your memory if your phone is not switched on?
Connect Redmi 7A to your PC in Fastboot mode (clamp Power + Volume down). Then use the command: fastboot erase userdata This will reset to factory settings without having to turn on the phone.
Why does MIUI show the wrong amount of free memory?
This is a well-known MIUI 10-12 problem on eMMC devices, where the system reserves some space for its needs (up to 3 GB), but does not display this in the interface. The actual free space is always less than shown in the settings.
