How to Clean Xiaomi TV Memory: From Cache to Complete Reset

Why Xiaomi TV is slowing down and how it relates to memory

Your Xiaomi Mi TV or Redmi Smart TV has become slow to switch channels, hang around when running apps, or even give out a “Not enough memory” error? 90% of the time, it’s clogged storage. Like smartphones, modern Android TVs accumulate cache, temporary application files and update debris, especially on models with 8-16 GB of internal memory (for example, Mi TV 4A or Redmi TV A55), where free space ends in just a few months of active use.

The manufacturer claims that the system cleans the data itself, but in practice it doesn't work well.

• 🐢 Slowing down the interface when navigating the menu
• 🔄 Spontaneous reboots during viewing
• 🚫 Errors of installing new applications ("No space enough")
• 📺 Artifacts when playing video (twitching, lags)

In this article, 5 proven ways to clean up memory, from simple (cache removal) to radical (factory reset), all of which have been tested on 2018-2026 models and do not require root rights or special knowledge.

Method 1: Cleaning the application cache manually

The fastest and safest method is to remove the cache of individual apps, which will not affect your data (Netflix login, bookmarks on YouTube), but will free up up to 1-3 GB of space, especially voracious streaming services and launchers.

Instructions:

1. Open Settings (cog in the upper right corner of the main screen).
2. Go to the Apps → Installed annexes.
3. Select an app (such as Prime Video or MEGOGO) and click Clear Cache.
4. Repeat for all applications where the cache size is greater than 100MB.

⚠️ Warning: Do not clear cache for com.miui.tvlauncher (PatchWall launcher) and com.google.android.gsf (Google services.

🎬 YouTube (cache up to 500MB)

🎥 Netflix/Prime Video Up to 1GB)

🎮 Game emulators (Dolphin, PPSSPP)

📱 Launchers (PatchWall, Google) TV)

🔄 System updates (folder) /cache)-->

If you don’t want to clean each application separately, use the Memory Cleanup feature in your settings.It deletes temporary files of all programs at a time, but less efficiently (leaves up to 30% of garbage).

Method 2: Remove Unnecessary Applications and Data

Many pre-installed apps on Xiaomi TV cannot be removed by standard means, but they can be disabled or removed updates, which will free up space and speed up the system.

How to find and remove unnecessary:

1. Go to Settings → Applications → Installed Applications.
2. Sort the list by size (click on the three dots at the top → Sort by size).
3. Select an unnecessary app (such as Mi Home if you are not using a smart home) and click:

Critical folder for cleaning: /storage/emulated/0/Android/obb/ — This is where game data is stored (up to) 5–10 Delete its contents through the file manager (e.g., GB, FX File Explorer).

adb shell pm disable-user --user 0 title.package

Method 3: Using the built-in "cleaner"

Xiaomi TVs with MIUI TV 3.0 and later have a built-in memory optimization tool.

• 🗑️ Temporary application files
• 📁 Empty folders and duplicates
• 🔄 Remnants of remote programs
• 📥 Unused. APK-file

How to start:

1. Open the settings → Device → Memory.
2. Click Memory Cleanup (or Optimize on New Models).
3. Wait for analysis (1-2 minutes) and confirm the removal.

⚠️ Warning: The Cleanup Wizard does not remove the cache of system applications (e.g. Google Play Services) and after it is worked, it is recommended to manually clean the launcher cache (com.miui.tvlauncher) and Google Play Store.

Method 4: Manual cleaning through ADB (for power users)

If standard methods didn't work, and the TV still slows down, you can connect to it via ADB (Android Debug Bridge) and do a deep cleaning. This method requires a PC and minimal command line knowledge, but allows you to remove system debris that is not available through the interface.

Step-by-step:

1. Turn on USB Debugging on your TV: Go to Settings → About TV. Press 7 times on Build Number to activate Developer Mode. Return to Settings → Additional → For Developers and enable USB Debugging.

USB 3.0

ADB Tools

adb.exe

adb devices

(Should be available, confirm access to TV)

adb shell pm trim-caches 1000G

(cleaning the cache of all applications)

adb shell rm -rf /data/local/tmp/*

(Temporary file removal)

For complete cleaning, you can also delete folders with logs:

adb shell rm -rf /data/log/*


adb shell rm -rf /cache/*

⚠️ Attention: Do not delete folders /system or /vendor — This will cause a TV to crash, and don't use the adb shell pm clear command for system applications (e.g. com.android.tv.settings).

💡

ADB-Cleaning is the most efficient way, but it requires caution. If you're not sure about the commands, use method 5 (reset to factory settings).

Method 5: Reset to factory settings (last chance)

If Xiaomi TV is so slow that even the menu opens with a delay and free memory is less than 500 MB, it’s time to do hard reset.This method will delete all data (apps, accounts, settings), but return the device to factory performance.

How to reset your settings:

1. Open Settings → Additional → Reset and Recovery.
2. Select Reset (or Delete all data on new models).
3. Enter. PIN-code (if installed) and confirm the action.
4. Wait for the reboot (5-10 minutes) and the TV will return to the "out of the box" state.
5. Use an external drive: Connect a flash drive or SSD through USB-port and transfer movies, games and applications to it (in the application settings, select Move to Modify to the port). USB). For Android models TV 11+ You can use the flash drive as an internal memory (formatted as Adoptable Storage).

Limit background activity:

Settings → Applications → ⚙️ (three dots) → Special access → Battery optimization

Turn off optimization for frequently used apps (like YouTube or Kodi).

Critical advice: Don’t install Google Play memory cleaners (like Clean Master or CCleaner) that consume resources themselves and often contain advertising software.

💡

For Xiaomi TV A Pro and later, the Easy Mode feature (Settings → Special Features → Easy Mode) is available. It turns off animations and background processes, saving up to 30% of memory.
