Memory Cleanup on Xiaomi Redmi: A Complete Guide to Secret Methods

Noticing that your Xiaomi Redmi is slowing down, apps are suddenly shutting down, and “Not enough memory” is increasingly being logged? 90% of the time is due to clogged storage. Even if you regularly delete photos and videos, the system continues to accumulate hidden debris: app cache, residual files after updates, duplicates and temporary data. On Redmi devices (especially the budget lines of Redmi Note, Redmi A or POCO), the problem is exacerbated by limited internal storage — often only 32-64 GB of which is available to the user less than 80%.

In this article, we will discuss 7 proven ways to clean memory, from basic (cache removal) to advanced (system partitioning via ADB), you will learn how to free up up to 15-20 GB of space without losing important data, as well as which applications and settings MIUI steal memory unnoticed. All instructions are relevant for devices on MIUI 12-14 (including HyperOS) and tested on models Redmi Note 12 Pro+, Redmi 10C and POCO X5.

1. Analysis of occupied memory: what exactly takes place?

Before we start cleaning, we need to understand which files are clogging up memory. MIUI has a built-in analyzer, but it often hides system data. Here's how to get the whole picture:

Open Settings → Phone → Memory. Here you will see a diagram of how you categorize your memory into Apps, Images, Videos, Audio, Documents, and more. The last one is the most insidious one, which hides cache, log files, and remnants of deleted programs, for example, after you uninstall Facebook, up to 500 MB of garbage can remain in your memory.

• 📊 System applications: MIUI It can reserve up to 8-12 GB for its own services (for example, com.miui.system or com.xiaomi.midrop.
• 🗑️ Cache and temporary files: Apps like Telegram, TikTok or Google Chrome accumulate cache up to 1-3 GB each.
• 🔄 Residual files: After updates MIUI I remember the old versions of the firmware (folder) /cache), occupying 1–2 GB.
• 📁 Duplicates and lost files: Photos from WhatsApp, screenshots, browser downloads – all copied into multiple folders (DCIM, Pictures, Download).

For detailed analysis, use third-party utilities like Files by Google or SD Maid (available in the Play Market) will show hidden folders, like: /data/data/ (cache), /Android/obb/ (game-play), /MIUI/backup/ (backups of settings. On Redmi with MIUI 14 folder /MIUI/debug_log can weigh up 500 MB - it can be safely removed.

2. Basic cleaning: removal of cache and debris

Start with simple methods that don’t require root rights or special knowledge, and these activities will free up 1-5 GB of memory in 5-10 minutes.

Clearing the application cache

Cache speeds up programs, but it grows to giant sizes over time, for example, Instagram can accumulate up to 1 GB of cache, and Google Play Services can accumulate up to 500 MB.

How to clean:

1. Go to Settings → Applications → Application Management.
2. Select an app (like Chrome) and click Clear Cache.
3. For mass cleaning, use Settings → Memory → Clean (in MIUI 14 this option is called “Free space”).

⚠️ Warning: Do not clear the cache for com.android.systemui or com.miui.home – this can cause interface failures MIUI.

Removal of downloads and duplicates

Download is the main dumping ground for unnecessary files, APK-files, archives, and folders. DCIM/Screenshots Pictures are full of duplicate screenshots and photos.

How to clean:

• 📂 Open Explorer (built-in or Files by Google) and go to /storage/emulated/0/Download.
• 🔍 Sort files by size and delete anything older than 3 months (especially.apk,.zip,.pdf).
• 🖼️ To find duplicate photos, use Gallery Doctor (pre-installed in the photo) MIUI) Duplicate Files Fixer.

APK-files (installation packages)

Archives (.zip,.rar over 6 months old)

Screenshots with the same content

Log files (.log,.txt from application folders)

Cleaning of the basket and cloud copies

Many people forget that deleted files first end up in a 30-day shopping cart, and apps like Google Photos or Mi Cloud can automatically back up data by duplicating it.

What to do:

1. Open the gallery. → Basket and clean it.
2. In Google Photos, go to Settings → Free up space.
3. Turn off autosynchronization in Mi Cloud (Settings → Accounts → Mi Cloud → Sync).

💡

If you install apps from APK frequently, check the /Download/APK folder, which may contain outdated versions of programs that take up hundreds of megabytes.

3. Advanced Cleanup: System Files and Hidden Folders

If the basic methods didn't work, it's time to dig deeper. MIUI There are hidden folders and system files that are not visible in a standard conductor, but take up gigabytes of memory. /data/log can weigh up 1 GB, yeah. /MIUI/debug_log — before 500 MB.

3.1 Deletion of log files and dumps

Android and MIUI are constantly creating error logs, memory dumps and debugging files, which are only needed by developers, but take up space.

How to delete:

• 📱 Use it. SD Maid (section "CorpseFinder") or 1Tap Cleaner to find unnecessary logs.
• 🔧 Manually (via Root Explorer or Root Explorer) ADB) delete the contents of the folders: /data/anr/ (error-tracking), /data/tombstones/ (dam), /MIUI/debug_log/ (logic MIUI).

⚠️ Note: Do not delete files in /data/data/ manually, it can break applications. Use only proven utilities.

3.2 Clean up the MIUI update cache

After each update, MIUI keeps the old firmware versions in mind, for example, after upgrading from MIUI 13 to 14, up to 1.5 GB of garbage can remain in the /cache folder.

How to clean:

1. Go to Settings → About the phone → System update.
2. Click on the three dots in the top right corner and select “Remove downloaded service packs”.

3.3. Removal of preloaded applications (bloatware)

Xiaomi installs dozens of unnecessary apps on Redmi: Mi Video, Mi Music, GetApps, games from Gameloft. These cannot be removed by standard means, but can be disabled or uninstalled through ADB.

List of safe applications to remove (do not affect the operation of the system):

For removal via ADB:

1. Connect your phone to your PC and enable USB Debugging (Settings → About Phone → MIUI Version → 7 times press to unlock the developer mode).
2. Enter in the command line: adb shell pm uninstall -k --user 0 com.miui.videoplayer (replace com.miui.videoplayer with the desired package).

4.Memory optimization: MIUI settings to save space

MIUI has built-in tools for automatic memory cleaning, but they are often disabled by default.Properly configured will save up to 1-2 GB per month.

Set-up of automatic cleaning

Enable the Smart Cleanup feature, which removes cache and temporary files when you lock the screen:

1. Settings → Battery and performance → Cleaning.
2. Activate the Auto Clean switch and set a schedule (e.g. daily at 3:00).

Background limitation for applications

Many programs (like Facebook or VK) continue to run in the background, accumulating cache.

• 🛑 Go to Settings. → Annexes → Permits → Autostart and disable Autostart for unnecessary programs.
• 🔄 B Settings → Battery → Select battery mode to “Saving Charge” – this will reduce background activity.

Transfer of data to SD-map

If your Redmi supports memory cards (such as the Redmi Note 11 or POCO M5), transfer the heavy files to the memory card:

• 📁 In the Explorer, select files. → «Move it» → choose SD-map.
• 🎮 For games, use the settings → Annexes → [play-name] → Warehouse → Change. → SD-map.

⚠️ Note: Not all applications support portability SD. For example, WhatsApp and Telegram will not allow you to move chat data.

💡

Automatic cleaning in MIUI only removes cache, but does not touch downloads, duplicates and system logs. For full optimization, use a combination of built-in and third-party tools.

Radical methods: resetting and flashing

If you've had less than 10 percent of your free memory manipulations and your phone is slowing down, you've got two options: hard reset or flashboot, which will bring the device back to factory status, but require backup.

2. Unpack the archive and run the Mi Flash Tool on your PC.
3. Connect your phone in Fastboot mode (clamp Volume down + Power).
