Xiaomi Redmi 4A Cleanup: 7 Ways to Free Memory and Speed Up Work

Why Redmi 4A is slowing down and how to fix it

Xiaomi Redmi 4A, released in 2016, is still a popular budget device, but over the years, even this “unkillable” device begins to slow down: applications open for a long time, the system freezes, and memory ends after installing a pair of programs, the reason is not the “weak hardware”, but the clogged system — accumulated cache, the remains of deleted applications and fragmented files.

In this article, we will look at 7 proven ways to clean up Redmi 4A that work on all versions of MIUI, from the old MIUI 8 to the current MIUI 14. You will learn how to make space without losing data, which tools to use and which to refuse, and pay special attention to hidden MIUI functions that are not written about in standard instructions, for example, cleaning system debris through the engineering menu.

Important: the methods are suitable for other models of the Redmi series with similar hardware (for example, the Redmi 5A or Redmi 3S), but some menu items may differ. All operations are safe, if you follow the instructions - the risk of "bricking" the phone is minimal.

1.Cleaning the app cache: a quick way without losing data

Cache is a temporary file that creates applications to speed up work. Over time, it takes up gigabytes of memory, but it can be deleted without harming programs. On Redmi 4A with 16 GB Storage, this is especially true.

How to clear the cache:

• 📱 Open the Settings. → Annexes → All applications
• 🔍 Select an app (such as YouTube or Facebook) and tap Clear the cache
• 🧹 For mass cleaning, go to Settings → Memory. → Clean and press Clear Cache
• ⚡ Use the Security App (Based-in Antivirus Xiaomi): Optimization → Deep cleaning

⚠️ Warning: Do not confuse Clear cache and Clear data! The second option will remove all the settings of the application (for example, logins in messengers). Cache can be cleaned even daily, and data - only when absolutely necessary.

2. Delete unnecessary files and "junk" through MIUI Cleaner

MIUI has a built-in Cleaner tool (newer versions – Security → Clean) that finds and removes:

• 🗑️ Residual files of remote applications
• 📁 Empty folders and duplicate photos
• 🎵 Unused. APK-files (installer residues)
• 📄 System Logs and Temporary Files

Instructions:

1. Launch the Security app (shield icon).
2. Slip the cleanup. → Deep cleaning.
3. Wait for analysis (can take 1-2 minutes on Redmi 4A).
4. Select file categories to delete and click Clear.

3. Cleaning the system partition: hidden methods

Method 1: Through the Engineering Menu (without root)

1. Open the Phone app and dial ##4636##.
2. Select Usage Statistics → Storage.
3. Tap Clear app data for system applications (e.g. Mi Video or Mi Music).

Replace com.miui.videoplayer with an unnecessary system application package.

⚠️ Warning: Removing system applications may disrupt the work MIUI. Before experimenting, back up through Settings → Additionally. → Backup.

4.Outload optimization: why the phone brakes after turning on
