How to Clean Xiaomi Redmi 5A: From Cache to Deep Optimization

Xiaomi Redmi 5A is one of the most popular budget smartphones, which is still actively used due to its reliability, but over time even this model begins to slow down: applications open for a long time, the system freezes, and memory is clogged with unnecessary files, 90% of the time it is not the hardware, but the debris of the software part.

In this article, we've got 7 proven ways to clean Redmi 5A, from basic to advanced, how to free up memory without losing data, which system tools to use and which applications to remove, and we'll focus on the hidden MIUI junk folders that are not mentioned in the standard instructions.

Important: All methods are tested on current MIUI versions (including MIUI 12.5 and MIUI 14 for Redmi 5A).If your smartphone runs on older firmware, some menu items may differ - but the logic remains the same.

1.Diagnosis: What exactly is stopping your Redmi 5A?

Before cleaning, you need to understand the source of the problem. On the Redmi 5A, with its modest 2/3GB of RAM and 16/32GB of brake memory, there are three reasons:

• 🗑️ Full storage – less than 10% of free space on the system partition.
• 🐢 Overloaded cache – temporary application files take up gigabytes.
• 👻 Background processes – autoloading unnecessary services and widgets.

To check the current state:

1. Open the settings → About the phone → Memory.
2. Pay attention to the schedule of use of RAM and internal memory.
3. Click Warehouse → Other apps to see the most “gluttonous” culprits.

⚠️ Note: If you see system files occupying more than 8 GB on a 16GB model in the Memory section, that’s fine. MIUI reserve space for updates and firmware cache.

2.Relieving Memory: What Can Be Deleted Without Risk

On the Redmi 5A with 16GB of storage, it is critical to clean up unnecessary files regularly.

• 📸 Photo and video: Move media files to MicroSD or the cloud (Google Photos, Mi Cloud). Delete duplicates using the Files by Google app (free in Play Market). Clear folder DCIM/.thumbnails — Here are the photos (may weigh up to a few). 500 MB!).
• 🎵 Music and downloads: Download folder is often clogged with outdated files (APK, PDF, Offline playlists Spotify/Music can weigh several gigabytes.
• 📱 App cache: Go to Settings → Annexes → App management. Sort by size and clear the cache from Facebook, Instagram, Telegram — they're the ones that accumulate garbage most often.

⚠️ Note: Do not manually delete Android folders, MIUI Or data at the root of the storage! This can cause a system failure. MIUI.

3. Deep Cleanup: Hidden Folders and System Garbage

MIUI creates many hidden folders that are not visible in a standard file manager, but take up space.

• 🔍 folder /sdcard/MIUI/sss — It stores temporary file files of the themes. You can delete all the content.
• 🗑️ folder /sdcard/MIUI/backup — backups of settings (if you did not make a backup manually, it can be cleaned).
• 📦 folder /sdcard/MIUI/gallery/cloud — Cloud Gallery cache (remove if you don't use Mi Cloud).
• 🔄 folder /sdcard/MIUI/extra — Residual files after updates.

To see the hidden folders:

1. Install the file manager for Solid Explorer or FX File Explorer.
2. Enable the display of hidden files in the manager settings.
3. Go to /sdcard/MIUI/ and delete the contents of the listed folders.

Critical folder /sdcard/MIUI/debug_log can weigh up 1 GB — you can clean it completely without any consequences, and these files are created to debug system errors and are not needed by the average user.

4. RAM optimization: how to reduce background load

On the Redmi 5A with 2GB of RAM, each megabyte counts. To reduce the load:

• ⚙️ Turn off the autoload of applications: Go to Settings → Annexes → Autostart. Turn off autoboot for Facebook, VK, Messages (except those you use daily).
• 🔄 Limit background activity: In Settings → Battery → Select Power mode Saving Charge – this will limit background processes. For individual applications (such as Telegram) in the battery settings, select Limit background activity.
• 📱 Use the "Lite" versions of the apps: Replace Facebook with Facebook Lite, Messenger with Messenger Lite. For Instagram and Twitter, use the web version via the browser (enable the Desktop option in Chrome).

⚠️ Note: Do not use RAM boosters from the Play Market (e.g. Clean Master or Play Store). DU Speed Booster: These applications consume resources themselves and often contain advertising software. MIUI Has a built-in optimizer – just click Clean in the menu of the latest applications.

💡

If the phone is slowing down, try restarting it in Safe Mode (hold the switch off button → long tap on "Stop" → "Reboot in Safe Mode"). This mode only works system applications, which will help identify the culprit of the lags.

5. Partition cache reset: radical method without data loss

If standard methods don’t work, try resetting the partition cache, which will delete temporary system files but won’t affect your data, photos or apps.

Instructions:

1. Turn off the phone.
2. Press the Power button + Volume up at the same time until the Mi logo appears.
3. Release the buttons and you will be taken to Recovery Mode (English menu).
4. Select Wipe & Reset → Wipe Cache (Manage volume buttons, confirmation – power button).
5. After cleaning, restart your phone (Reboot → Reboot to System).

This method helps in cases where:

• The phone hangs on the logo when turned on.
• Applications are spontaneously closed.
• The system says "No memory" even though there's a place.

💡

Partition cache reset is the only safe way to clean system files without losing data. Don't confuse it with wipe data, which will delete all the contents of your phone!

6.Remove embedded MIUI applications (for advanced ones)

MIUI installs many pre-installed applications that cannot be removed by standard means, but can be disabled or removed with ADB (no root rights!).

List of safe applications to remove:

Instructions for removal through ADB:

1. Turn on USB Debugging in Settings → About Phone → MIUI Version (stick 7 times) → Additional → For Developers.
2. Connect your phone to your PC, install ADB drivers.
3. Open the command line and type: Adb devices (the device should appear).
4. To remove an application (e.g. Mi Video): adb shell pm uninstall --user 0 com.miui.videoplayer

⚠️ Warning: Do not delete system applications with packages com.android., com.miui. (except for those listed)! This can cause the phone to fail. If in doubt, it is better to turn off the application in the settings (Settings) → Annexes → Select an application → Shut down).

7. Alternative firmware: when cleaning doesn't help

If Redmi 5A slows down even after all the manipulations, it is worth considering the firmware reflash: official global MIUI firmware is often overloaded with unnecessary services, and custom ones (for example, LineageOS or Pixel Experience) run faster.

Advantages of custom firmware for Redmi 5A:

• ⚡ Higher performance due to optimized core.
• 🆓 Less pre-installed garbage (no Mi apps).
• 🔄 Longer support for updates (official updates for Redmi) 5A They stopped in 2020).

Recommended firmware:

• Pixel Experience is a pure Android with support for Google Services.
• LineageOS is a stable firmware with a minimalist interface.
• Havoc-OS is a customizable firmware with many functions.

⚠️ Attention: Installing custom firmware will reset all data and require unlocking the bootloader. 5A Unlocking takes 72 hours (according to Xiaomi rules). 4PDA model-themed.

💡

Custom firmware can bring back a second life to the Redmi 5A, but it requires technical skills. If you've never stitched your phone, you'd better see a specialist.
