Xiaomi Deep Cleanup: What You Can Remove Without Risk to Your System

Xiaomi’s MIUI-based smartphones are known for their functionality, but over time, even the most productive models start to “brake” because of clogged memory. Conventional cleaning through built-in tools (Settings → Memory) removes only the tip of the iceberg — temporary files and app cache. However, deep cleaning allows you to free up much more space by removing unnecessary system data, duplicates and residual files from long-deleted programs.

The problem is that not all files can be deleted without risk. Mistakes can cause MIUI malfunctions, loss of functionality, or even “bricking” of the device. In this article, we will look at what data can be safely deleted on Xiaomi, Redmi and POCO smartphones, what tools to use, and how to avoid critical errors.

Why Standard Cleaning Doesn't Help: Hidden Sources of Garbage

The built-in Cleanup utility in MIUI only removes surface debris: user app cache, temporary download files and image thumbnails. However, the main memory eaters remain intact:

• 📁 System cache (/cache and /data/dalvik-cache) — takes 1–3 GB, but does not clean automatically.
• 🗑️ Residual files of remote applications – remain in folders /data/data and /sdcard/Android/data.
• 🔄 Duplicates of media files created by Xiaomi Gallery and messengers (for example, copies of photos from Telegram or WhatsApp).
• 📦 APK-Update files that are downloaded to /sdcard/Download/rom and not removed after installation.

Besides, MIUI actively uses a preloaded cache to speed up the launch of applications. /data/system/package_cache They can take hundreds of megabytes, and standard tools don't touch them, because they're considered "useful" for performance, but if memory is critically scarce, they can be manually cleaned.

⚠️ Note: Delete files from the folder /system or changing the permissions to access system partitions without unlocking the bootloader and root rights will lead to a device blink. /sdcard (internal memory; and /data (rooted).

What can be removed without root rights: safe methods

If you don't have an unlocked bootloader or superuser right, you can still free up a few gigabytes of memory by manually deleting unnecessary data, here's a list of folders and files that can be cleaned without risk:

To clean these folders, use any file manager with hidden file access (e.g. Mi File Manager with the Show Hidden Files option enabled or Solid Explorer).

Delete the app cache in /sdcard/Android/data/*/cache

Clear /sdcard/Download/rom folder from old APKs

Remove logs from /sdcard/MIUI/debug_log

Check the messenger folders for unnecessary media files

Clean the basket in the Xiaomi Gallery (Albums → Cart)

-->

If you are actively using Google Photos or other cloud storage, check the /sdcard/DCIM/.thumbnails folder – it stores thumbnails of all photos and videos that can be safely deleted (they will be restored automatically the next time you view them).

Once a week.

Cleaning system cache and Dalvik-cache (root required)

If you have root rights, you can remove system debris that is not touched by standard methods.

• 🧹 Dalvik-cache (/data/dalvik-cache) — Android virtual machine cache that recovers automatically but can take up to 1 GB.
• 🗃️ System cache (/cache) — Temporary update files and logs that accumulate over time.
• 📦 Residual APK (/data/app-lib) — remote application library.

Use Root Explorer or the command in Terminal Emulator to clean:

su


rm -rf /data/dalvik-cache/*




rm -rf /cache/*

Once cleaned, restart the device, the system will restore the necessary files automatically, and if there are errors in the application after the reboot, repeat the cleanup and restart again.

⚠️ Note: Removing files from /data/dalvik-cache device-wise MIUI 13/14 This can lead to long-term optimization of applications at first launch (before the first run). 10–15 Don't interrupt the process!

💡

Before cleaning dalvik-cache, back up /data/dalvik-cache to your computer. If the system is unstable after the restart, you can restore the files back.

Removing Xiaomi’s built-in apps (debloat)

MIUI is known for a large number of pre-installed applications, many of which cannot be removed by standard methods.

• 🎵 Mi Music and Mi Video – if you use YouTube Music or VLC.
• 📰 Mi Browser – if you prefer Chrome or Firefox.
• 📱 Mi Pay, Mi Credit – if you do not use Xiaomi payment services.
• 🎮 Game Turbo – If you don’t play mobile games.

These applications can be removed in two ways:

1. Through ADB (no root, but requires a PC connection):

adb shell pm uninstall -k --user 0 com.miui.videoplayer


adb shell pm uninstall -k --user 0 com.miui.player

1. With root (complete removal):

Use Titanium Backup or System App Remover to uninstall. A full list of removal packages can be found in the themes on XDA-Developers for your model.

⚠️ Warning: Removing system applications may disrupt the work MIUI. For example, deleting Mi Security (com.miui.securitycenter) will cause the Security section to disappear. Before deleting, check if the application is critical (such as Mi Share for file transfers).

Cleaning up duplicates and unnecessary media files

One of the biggest memory eaters on Xiaomi is duplicate photos and videos, which are created by:

• 📸 Automatic copy creation when editing in the Xiaomi Gallery.
• 🤖 Sync with Google Photos or Mi Cloud (files duplicated in different folders).
• 📱 Saving media from instant messengers (Telegram, WhatsApp) to the main gallery.

To find duplicates, use applications like Files by Google (built-in Clean → Duplicate Files Fixer) or Duplicate Files Fixer.

/sdcard/DCIM/Camera


/sdcard/DCIM/Screenshots




/sdcard/Pictures




/sdcard/Android/media/com.whatsapp/WhatsApp Media

On devices with MIUI 14 and later, duplicates can be hidden in /sdcard/MIUI/Camera/ folder, which stores temporary copies of photos taken in Pro Mode or with effects.

💡

Before mass deletion of duplicates, sort files by date of change, often older than copies created by messengers or cloud services.

Storage optimization: what else can be done

In addition to deleting files, the following steps help to free up space on Xiaomi:

• 🔄 Transfer of applications to SD-map (if supported) C Settings → Annexes → Application Management Select Program and Click Transfer to SD.
• ☁️ Disable automatic download of media in messengers. in Telegram: Settings → Data and memory → Autoboot media.
• 📂 Archiving rarely used files, for example, old photos can be packaged in ZIP and move it to the cloud.
• 🔄 Reset Google Play Services cache. Go to Settings → Annexes → All applications → Google Play Services → Memory. → Clear the cache.

If you are using Mi Cloud, check your sync settings: by default, Xiaomi can automatically upload not only contacts to the cloud, but also the ones that are connected to the cloud. SMS, Notes and application backups, which take up space in both the cloud and the device (in the folder). /sdcard/MIUI/backup). Turn off unnecessary synchronization in Settings → Xiaomi account → Mi Cloud.

What not to do with deep cleaning

Some actions can lead to irreversible consequences, and this is strictly forbidden:

• 🚫 Delete or modify files in folders /system, /vendor, /boot rootless and knowledgeable of consequences.
• 🚫 Format a section /data Recovery without backup (this will erase all user data).
• 🚫 Delete the folder /sdcard/Android/obb whole - game data is stored here (remove only unnecessary subfolders).
• 🚫 Clear the cache of applications that work with important data (for example, WhatsApp, Banking applications).

It is also not recommended:

• ⚠️ Use cleaners like Clean Master or CCleaner – they often delete useful data and slow down the system.
• ⚠️ Clearing Google Play Services cache more than once a month can lead to push notification errors.
