Memory Cleanup on Xiaomi Redmi 4A: A Complete Guide with Proven Methods

Xiaomi Redmi 4A is one of the most popular budget smartphones, but its main drawback is only 16 GB of internal memory (of which the user can access about 10-11 GB), over time, even this modest amount is clogged with photos, app cache and system files, which causes the phone to slow down and new applications are not installed. In this article, we will analyze 7 working methods of cleaning memory, from simple to radical, and also explain how to prevent re-clogging.

The Redmi 4A feature is that there is no memory card slot in the base version (16 GB). Even if you have a modification that supports microSD, transferring applications to an external drive often does not work properly due to the limitations of MIUI. So cleaning internal memory remains the only reliable solution. It is important to understand that just delete files is not enough – you need to optimize the system so that the memory does not get clogged again in a week.

1. Analysis of occupied space: what exactly eats memory?

Before you clean, figure out which files take up the most space.

• 📊 Go to Settings. → Memory (or Settings) → Storage in new versions MIUI). Here you will see a diagram of the memory distribution by category: Applications, Images, Video, Audio and Other.
• 🔍 Click on any category (like Apps) to see a list of the most voracious programs. Most often, the culprits are instant messengers (Telegram, WhatsApp), social networks (TikTok, Instagram), and games.
• 📁 Check the Download folder – unnecessary ones accumulate here. APK-Files, documents and archives. Path: File Manager → Internal memory. → Download.

A typical picture for the Redmi 4A after a year of use:

⚠️ Note: If the “Other” section is more than 2 GB occupied, this is a sign of clogging with system junk files, they can not be removed manually, you will need a reset or special utilities (see section 5).

2.Cleaning App Cache: A Quick Way to Free 1–3 GB

Cache is a temporary file that applications create to speed up work, accumulate over time and take up gigabytes of memory. Clearing the cache does not delete important data (logins, messages, game progress), but can reset some settings (for example, login sites).

Cleaning methods:

• 🧹 Through Settings: Settings → Annexes → Select an application → Memory. → Clear the cache. Use Settings for mass cleaning. → Memory. → Clear the cache (button at the bottom of the screen).
• 🤖 With File Manager: Open the File Manager → Cleanup → Cash. You can select applications here to clean selectively.
• 🚀 Automatic Cleanup: Enable the option in Settings → Memory. → Autocleaning (it is recommended to set an interval of 1 time per week).

On Redmi 4A, Google Play Services cache can take up to 1GB – it must be manually cleaned, as automatic cleaning often skips system applications.

Close all applications (swipe up in the multitasking menu)

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

Check the free space after cleaning in Settings → Memory

Restart your phone to apply changes-->

3. Delete unnecessary files: photos, videos, APK

Media files are the main memory eater, and Redmi 4A is particularly critical.

• 📸 Photo Duplicates: Created by editing in Gallery or Google Photos. Use Files by Google (free in Play Market) to find duplicates.
• 🎥 Videos from social networks: TikTok, Instagram and WhatsApp automatically save videos to the folder DCIM/.thumbnails or WhatsApp/Media. Remove them manually.
• 📦 APK-Files: Installation packages remain in the Download folder even after you install the application. Securely delete all files with the.apk extension.
• 📄 Downloads: PDF, DOCX, XLSX — You don't need these files all the time. Move your important documents to the cloud (Google Drive, Yandex Disk) and delete your local copies.

How to find and delete:

1. Open File Manager → Categories → Images / Videos.
2. Sort files by size (click on three dots in the top right corner → Sort → by size).
3. Delete files older than 6 months (if not needed). Use Multiple File Selection Mode (long-click on file → ticks) for convenience.

💡

In Google Photos, enable the “Free Space” function (Settings → Free Space) and the app will automatically delete local copies of photos that have already been uploaded to the cloud (provided you have a backup!).

4. Optimization of messengers: how to stop the auto-saving media

Messengers are the main culprits of memory clogging, such as WhatsApp defaults to save all photos and videos received to the WhatsApp/Media folder, while Telegram caches media files to Telegram/Telegram Images. On Redmi 4A, this can eat up to 5 GB per month!

How to set up auto-save:

In addition:

• 🗑️ Regularly clean the folders of messengers manually: File Manager → Internal memory. → WhatsApp/Media (Delete everything except the WhatsApp Databases folder – it stores backups of chats).
• 🔄 In Telegram, use the function "Clear cache" (Settings) → Data and memory → Clear cache.This will delete all uploaded media files, but will not affect chat rooms.

⚠️ Note: If you use WhatsApp Business, do not delete the Databases folder, this will lead to loss of chat history. To clear the cache, use only the built-in feature in the application settings.

5. System garbage removal: logs, temporary files, update residues

System files (.log,.tmp, remnants of MIUI updates) can take up to 2 GB of memory, but they can not be deleted by standard means.

• 🛠️ Built-in utility MIUI: Security → Cleanup → Deep Cleanup: You can delete the remnants of deleted applications, temporary files and cache of the system.
• 🤖 Third-party annexes: SD Maid (requires root) or Files by Google (runs without root) are tools that find junk files that the standard file manager can't see.
• 🔄 Cleaning Dalvik cache: If the phone began to brake after the update MIUI, Cleaning the Dalvik cache can help. You need to go to Recovery Mode (turn off your phone, then press Volume).+ + Food before the appearance of the logo MI). In the recovery menu, select Wipe → Wipe Dalvik Cache.

Redmi 4A often has old firmware files in /cache on its upgrade to MIUI 12+, which can only be deleted through recovery or root access.

6. Transfer applications to a memory card (if supported)

If your Redmi 4A supports microSD (a two-slot modification), some applications can be transferred to an external drive.

• ✅ You can transfer: Most user applications (games, instant messengers, social networks).
• ❌ Cannot be transferred: System applications (Google Play Services, MIUI System, widgets, applications with administrative rights.
• ⚠️ Problems: Some apps are slower or have errors (especially games) after a transfer).

How to move:

1. Insert a memory card (class 10 or UHS-I is recommended for speed).
2. Go to Settings → Applications → Select Application → Memory → Change → SD Card.
3. Confirm the transfer. The process may take a few minutes.

Important:

• The memory card must be formatted as internal memory (in which case it becomes part of the system and encrypted).
• After transferring the application to SD, it cannot be run without a card - the phone will give an error.

7. Reset to factory settings: a radical method

If all previous methods failed and the phone has less than 1 GB of free space, it will be a hard reset that will delete all data, including apps, photos, accounts and settings, but will return the phone to a “clean” state.

1. Turn off the phone.
2. Hold the volume.+ + Food before the appearance of the logo MI (recovery).
3. Select Wipe Data → Wipe All Data (manage volume buttons, confirmation – power button).
4. After reset, select Reboot.

⚠️ Attention: On Redmi 4A post-discharge IMEI (Communication module ID) if you have previously changed firmware or obtained root access, in which case the phone will lose the network. IMEI, typing *#06# - it should be displayed.

💡

Factory reset is the last way other methods didn't work. Once reset, the phone will run faster, but you'll have to reconfigure all the applications and restore the data from the backup.
