Cleaning Xiaomi Redmi 7A from unnecessary files: 7 proven ways

Your Xiaomi Redmi 7A is slowing down and your memory is filled with obscure files? Even a budget smartphone with 2GB of RAM and 16/32GB of storage can be brought back to life without a radical reset. The problem is not the weak hardware — in 90% of cases, system debris, remnants of deleted applications and duplicate media files that have been accumulated in memory for years.

This guide will help you free up 3-8 GB of space on the Redmi 7A without root rights or special knowledge. We will analyze both standard MIUI tools and hidden features that are not mentioned in the official guides. Importantly, the methods are suitable for all firmware versions (including MIUI 12/14), but taking into account the features of the Redmi 7A, its low-power Snapdragon 439 processor and limited memory.

1.Diagnostics: what exactly is taking up memory on the Redmi 7A

Before you clean, you need to understand the source of the problem. On the Redmi 7A, memory is clogged for three main reasons:

• 📱 System cache – temporary application files and MIUI, which should be cleaned automatically but often remain (especially after updates).
• 🗑️ Residual data – “tails” from remote programs (for example, folders) /Android/obb/ play-off).
• 📸 Duplicates and junk media – screenshots, uploaded from instant messengers pictures, Google cache Photos.

To see the full picture:

1. Open the settings → About the phone → Storage.
2. Click on the memory usage chart – the system will show the distribution by category.
3. Pay attention to the "System Data" and "Other" items - if they take >2 GB, it's time to clean.

The Redmi 7A has a peculiarity: due to the small amount of memory (eMMC 5.1), even 1-2 GB of garbage can cause freezes when multitasking. For example, if less than 10% of storage is free, the system begins to aggressively reset background processes - hence the "dumping" of applications.

2.Cache cleanup: system and applications

Cache is a temporary file that should speed up work, but in practice often turns into ballast. On Redmi 7A, the cache can be cleaned in three ways:

Method 1: Standard cleaning in MIUI

1. Go to Settings → Applications → Application Management.
2. Select an app (like Facebook or YouTube) → Storage → Clear cache.
3. For mass cleaning: Settings → Storage → Cleanup → select “App Cache”.

Method 2: Hidden function "Deep cleaning"

MIUI has an undocumented system cache removal tool that is not visible in the standard menu:

1. Open the phone and dial ##4636##.
2. Select "Battery Statistics" → "Clear Cache" (if there is no item, go to method 3).

Method 3: Through Recovery (for experienced)

If the phone is slowing down, cleaning Dalvik-cache will help:

1. Turn off Redmi 7A.
2. Press Power + Volume up until the Recovery menu appears.
3. Select Wipe & Reset → Wipe Cache (not to be confused with Wipe Data!).

Close all applications

Connect your phone to charge (if charge < 30%)

Make a backup copy of important data

Do not interrupt the cleaning process.-->

⚠️ Warning: Clearing the cache through Recovery will reset some application settings (such as authorization in games).Do not confuse Wipe Cache with a full reset (Wipe Data) - this will delete all your data!

After cleaning the cache, Redmi 7A can run slower for the first 10-15 minutes, which is normal: the system recovers the necessary temporary files, but after an hour you will notice that the memory is freed up by 500 MB-1.5 GB.

3. Removal of residual data and “tails” of applications

When you uninstall an app through Play Market or Settings, it often leaves behind:

• 📂 Folders in /Android/obb/ (game data, weighing up to 1-2 GB).
• 📄 Settings files in /data/data/ (root-only).
• 🖼️ The messenger cache in /Android/media/ (Photos, videos, stickers).

To remove this garbage:

Step 1: Cleaning the OBB folder

1. Connect your phone to your PC or use a file manager (such as Mi File Manager).
2. Go to the internal memory → Android → obb.
3. Delete folders with the titles of games you deleted a long time ago (e.g. com.tencent.ig is PUBG Mobile).

Step 2: Removing the messenger cache

WhatsApp, Telegram and Viber cach all media files to clear:

• 💬 WhatsApp: ⋮ → Settings → Warehouse → Storage management → Sort by size and delete unnecessary files.
• 📎 Telegram: ⋮ → Settings → Data and memory → Clear the cache.

On Redmi 7A, the /Android/data/ folder often contains up to 2-3 GB of junk from long-deleted applications, and can only be cleaned via a PC or root access.

4. Optimization of photos and videos

Media files are the main memory eater on Redmi 7A. Even if you don’t shoot videos, instant messengers and social networks automatically upload hundreds of MB of content in the background.

Method 1: Automatic cleaning through Google Photos

If you are using Google Photos:

1. Open the app. → ⋮ → Settings → Make room.
2. The system will prompt you to delete local copies of photos that have already been uploaded to the cloud.

This will free up 1-3GB, but make sure the files are actually synced!

Method 2: Manual sorting of duplicates

Use applications like Files by Google or CCleaner:

1. Open the application → select “Clean up” → “Duplicate files”.
2. View the suggested take (especially screenshots and uploaded pictures).
3. Remove the unnecessary ones – it will free up 300-800 MB.

💡

To prevent automatic downloading of media from chats, on WhatsApp, disable the option “Autoload Media” in the storage settings. This will save up to 1 GB per month.

5. Cleaning system logs and dumps

Android is constantly creating error logs and memory dumps that only developers need. On Redmi 7A, they can take up to 1 GB in /data/tombstones/.

They can be removed:

1. Through ADB (PC required):
2. Or using the SD Maid app ("CorpseFinder" section).

⚠️ Note: Removing logs through ADB requires on-set debugging USB (Settings → The phone. → Version. MIUI → 7 times press to unlock the developer mode, then additionally → For developers → Debugging by USB). Wrong commands can damage the system!

If you are not sure about working with ADB, use SD Maid - it safely clears logs without root. After deleting, reboot your phone: this will free up an additional 200-500 MB.

6. Disconnecting unnecessary system processes

MIUI on Redmi 7A runs a lot of background services that consume memory and battery power, some of which can be turned off without consequence.

List of safe services for disabling:

• 🔄 Auto-update MIUI (com.miui.systemAdSolution – checks for background updates.
• 📊 Xiaomi Analytics (com.miui.analytics) – sends usage data.
• 🎵 Music player MIUI (com.miui.player – if you don’t use it.
• 📰 News MIUI (com.miui.miservice – News Feed on the Main Screen.

To disable:

1. Go to Settings → Applications → Application Management → All applications.
2. Find a service by name (e.g., Analytics).
3. Press "Disable" (if the button is inactive, first click "Stop").

💡

Disabling system applications does not remove them completely, but only stops the background work.It is safe, but some functions (for example, the news feed) will stop updating.

Once you disable unnecessary services, Redmi 7A will be less likely to “hang” when opening applications, especially on models with 2 GB of RAM, where each background process takes precious resources.

Alternative methods: from formatting to resetting

If you've had less than 1GB of free memory after all the manipulations, it's time to consider radical measures.

Option 1: Formatting a memory card (if used)

If you use microSD as internal memory (Settings → Storage → SD card → Formatted as internal storage), it can be formatted without losing data on the main storage.

• 📁 Map infected with viruses.
• 🐢 It works very slowly (cheap Class 4 microSDs slow down Redmi). 7A).

Option 2: Reset to factory settings

If the garbage has grown so large that it cannot be removed manually, it is hard reset. On the Redmi 7A, it is done like this:

1. Make a backup (Settings → Additional → Backup and Reset).
2. Go to Settings → About the phone → Reset settings.
3. Select “Erase All Data” (not “Reset” – this will only delete settings, not files!).

⚠️ Attention: After the Redmi reset 7A It will work faster, but all data (including photos and messages) will be deleted! If the phone is linked to a Mi Account, after the reset you will need to enter a login and password.

Resetting is a last resort, but sometimes it’s the only way to get the Redmi 7A back to factory speed, install only the apps you need after the procedure, and clean the cache regularly to avoid clogging again.
