Memory Cleanup on Xiaomi Redmi 4A: from cache to deep reset

Xiaomi Redmi 4A (released in 2016) is still a popular budget smartphone, but its main problem is a lack of internal memory. Only 16 GB (of which ~10-12 GB is available) quickly clogged with system files, app cache and debris from MIUI. If your phone writes “Memory is full” or slows down when installing new applications, this article will help it return to work.

We will discuss 7 working methods, from simple (cache removal) to radical (factory reset), and how to avoid re-clogging memory. All instructions are relevant for Redmi 4A based on MIUI 8-14 (including global and Chinese firmware), especially focusing on hidden system folders that take up to 3-5 GB of space, but do not appear in the standard file manager.

1. The analysis of occupied memory: what exactly eats the place?

Before you clean, you need to understand which files take up the most space. Redmi 4A has built-in tools and third-party utilities for this.

Open Settings → Memory (or Settings → Storage in newer versions of MIUI) and here you will see a diagram of the memory distribution by category:

System files (usually 4-6 GB, including firmware and updates)

- Annexes (APK-file)

- Media files (photos, videos, music)

- Cash (temporary files)

Other (often the most "heavy" files are hidden here)

Click on the "Other" category - that's where the underlying problem usually lies. Redmi 4A tends to accumulate:

- System logs (.log,.txt)

Residual files of remote applications (.apk,.obb)

Google Play Services cache (can weigh up to 1-2 GB!)

- Folders of temporary files from messengers (Telegram, WhatsApp)

💡

If you see a MIUI or Xiaomi folder weighing more than 500 MB in the Others section, you can clean it up. These are update residues and backups of your settings.

• 📊 Built-in Analyzer: Shows the big picture, but isn’t always accurate for small files.
• 🔍 Files by Google (Free in Play Market): Finds duplicates, large files and junk.
• 🛠️ SD Maid (paid version): Deep scanner for power users (requires root for full access).

2. Cleaning the application cache and system

Cache is a temporary file that creates applications for fast work. On Redmi 4A, the cache can take anywhere from 500 MB to 3 GB, especially if you are actively using social networks, messengers or games.

To clear the cache of all applications at once:

1. Go to Settings → Memory → Clear the cache.
2. Confirm the action (may take 1-2 minutes).

This method is secure and does not delete important data (logins, messages, game progress).

For selective cleaning of the cache of individual applications:

1. Open Settings → Applications → All applications.
2. Select the app you want (like Facebook or YouTube).
3. Press Warehouse. → Clear the cache.

Redmi 4A also has a hidden system cache that is not visible in the standard menu.

1. Turn off the phone.
2. Press Volume Up + Power before the Mi logo appears.
3. In the Recovery menu, select Wipe & Reset → Wipe Cache (control – volume buttons, choice – power button).

This method helps if the phone has become very slow after the MIUI update.

3. Removal of unnecessary applications and their residues

Even after the applications are removed, Redmi 4A still has residual files, such as folders with settings (.data), cache (.cache) and downloads (.obb), which can take up to 1-2 GB and not appear in a standard file manager.

To completely remove the application together with its data:

1. Go to Settings → Applications → All applications.
2. Select an unneeded app (such as Mi Video or Mi Music if you don't use them).
3. Click Delete and then Clear Data (if the button is active).

4. Optimization of media files: photos, videos, music

Media files are the main memory eater on Redmi 4A. Even if you do not shoot videos, messengers (WhatsApp, Telegram) and social networks automatically save photos and GIFs to the DCIM or Pictures folder.

How to make room:

1. Transfer files to the memory card (if installed). To do this: - Open Files (standard MIUI manager). - Select DCIM, Pictures, Download folders. - Click Move → Memory map.
2. Remove duplicates. Use Files by Google (Clean Up → Duplicate Files) or CCleaner.
3. Compress photos. Apps like Photo Compress will reduce the weight of photos without losing quality.

Pay special attention to the messenger folders:

WhatsApp: /WhatsApp/Media/ (all photos and videos are stored here).

- Telegram: /Telegram/Telegram Images/ and /Telegram/Telegram Video/.

These folders can be manually cleaned or set up autoclean in the messenger settings.

5. Cleaning system files and logs

System logs (.log,.txt,.dump) are files that MIUI creates for debugging. On Redmi 4A, they can take anywhere from 200 MB to 1 GB, especially if the phone is rebooted frequently or errors occur.

To remove them:

1. Open a file manager with root permissions (such as Root Explorer) or use ADB.
2. Go to the folders: /data/log/ - /data/anr/ - /data/tombstones/ - /cache/
3. Delete all files with extensions.log,.txt,.dump.

If you don’t have root rights, use the Android Debug Bridge (ADB):

1. Connect Redmi 4A to your PC and enable Debugging over USB (Settings → About Phone → MIUI Version – Press 7 times, then go back to Settings → Additional → Developers).
2. Open the command line on your PC and type in: adb shell su rm -rf /data/log/* rm -rf /data/anr/* rm -rf /data/tombstones/*

This method requires minimal ADB knowledge, but is safe if you follow the instructions.

💡

6.Reset to factory settings (last chance)

If all previous methods failed and the Redmi 4A has less than 1 GB of free space, you will have to do a full reset, which will delete all data, including:

- Applications and their settings

- Photos, videos, music.

Accounts and passwords (except Mi Account information if the phone is linked to a Xiaomi account)

How to reset your phone:

- Save the list of installed applications (you can use App Backup & Restore).

Write down your account logins and passwords (or use Google Smart Lock for auto-recovery).

7.How can we prevent future memory clogging?

To avoid recurring problems, follow these tips:

Disable auto-save media files in messengers (WhatsApp, Telegram).

Install a memory card (up to 128 GB) and transfer applications to it (via Settings → Applications → Move to SD).

Clean the cache regularly (once every 1-2 weeks).

Use cloud storage (Google Photos, Mi Cloud) to automatically upload photos and videos.

• 📵 Do not play heavy games (for example, PUBG Call of Duty – they take up to 2-4 GB and brake heavily on the Redmi 4A.
• 🔄 Update. MIUI, not through OTA (by air), and manually - so less debris remains after installation.
• 🚫 Avoid cleaners like Clean Master – they often create more problems than they solve.
