How to Clean Cache on Xiaomi TV: The Complete Guide

Why Clean Cache on Xiaomi TV and When to Clean It

Cache on Xiaomi TVs (Mi TV, Redmi TV, Xiaomi TV A) are temporary files that are created by apps and the system to speed up work. Over time, they accumulate, take up precious space in memory and can cause disruptions, from slow loading YouTube or Netflix to a complete freeze of the interface.

Cleaning the cache is recommended in the following cases:

• 📉 The TV began to slow down when switching between applications.
• 🔄 Annexes (e.g, IVI or Kinopoisk) is constantly rebooted.
• 🚫 Errors such as “Not enough memory” or “The app has stopped” appear».
• 🔍 In the storage settings, it is clear that the "Cash" takes 1 GB+.
• 📺 After the firmware update, the TV is unstable.

It is important to understand the difference between cache and user data. Cache are service files that can be deleted without risking personal information. But cleaning the application data (such as logins or bookmarks) will lead to their loss. On Xiaomi TVs, these options are separated, but in some menus they can be displayed together - be careful!

Method 1: Clearing the cache for a separate application

If you only have problems with one application (like Tricolor TV or Megogo), clear the cache for it only, which is the safest method, since it does not affect system files.

Instructions:

1. Open Settings (cog in the upper right corner of the main screen).
2. Go to the Applications section → Installed Appendices.
3. Select a problem app (like YouTube).
4. Click Clear Cache (not to be confused with Clear Data!).
5. Confirm the action and restart the TV (Settings → About TV → Reboot).

Close all applications (return to the main screen)

Connect the TV to the network (in case of update after cleaning)

Make sure the remote is charged (the process can take 1-2 minutes)

Do not press buttons on the remote during cleaning.-->

Some apps (like Netflix or Disney+) may require login re-entering after cleaning the cache, which is normal because they recreate temporary files. If the app still doesn't work properly after cleaning it, try reinstalling it or contact the service.

⚠️ Attention: On Xiaomi TVs TV A2 Redmi Smart TV X 2023 in the application menu may not have a button to clear the cache. In this case, use Method 3 (system cleaning).

Method 2: Automatic cleaning through “Memory Optimization”

Xiaomi Android TVs or Google TVs (Mi TV Q2, Xiaomi TV P1 and later) have a built-in tool for automatic cache cleaning and RAM release.It is less efficient than manual cleaning, but it is safe and does not require technical knowledge.

How to start:

1. Open the settings → Device → Memory.
2. Choose Memory Optimization (or Waste Cleanup on Old Firmware).
3. Wait for the scan to be completed (usually 10–30 seconds).
4. Click Clean and confirm the action.

This method does not delete the cache of individual applications, but only clears the system temporary files. If you need to free up the maximum amount of memory, combine it with Method 1 or Method 4 (full reset).

💡

After automatic cleaning, restart the TV – this will help the system correctly recalculate the free space and avoid errors when installing new applications.

Method 3: Cleaning the cache through the engineering menu (for advanced)

If standard methods don't work, you can use the engineering menu (or service mode), which is suitable for PatchWall models (Xiaomi firmware) and allows you to clear the cache deeper, including system files. Careful: improper actions in the engineering menu can lead to a failure of the TV!

Step-by-step:

1. Turn on the TV and go to the main screen.
2. On the Xiaomi remote, press and hold the buttons at the same time: Menu + Back up (←) + Home (🏠) Hold for 10-15 seconds until the service menu appears.
3. From the menu that opens, select Advanced Settings → Storage.
4. Find Clear Cache (or Wipe Cache Partition) and confirm the action.
5. Wait until the process is complete (the TV can restart).

On some models (Redmi TV A55, Mi TV 5 Pro) the path may be different.

Service Menu → Factory Mode → Clear eMMC

In this case, choose Clear Cache Only, not Full Erase (the latter will delete all data!).

⚠️ Warning: If after cleaning the cache through the engineering menu, the TV freezes on the Xiaomi logo, do not panic. Wait 5-10 minutes - the system recovers files. If the freeze lasts longer, perform a hard reset (Reset button on the back of the TV panel).

Method 4: Complete factory reset (extreme case)

If the TV is slowing down, the apps won't open, and cleaning the cache doesn't help, you're left resetting to factory settings, and this method deletes all data, including accounts, installed apps, and personal settings, and only use it as a last resort!

How to reset:

1. Open the settings → About the TV → Reset.
2. Select Reset to factory settings (or Full Reset).
3. Enter the password from your Xiaomi account (if tied) or the TV PIN.
4. Confirm the action and wait until the completion (it will take 3-7 minutes).

After resetting, the TV will return to a boxy state.

• 🔧 Reconfigure Wi-Fi and account login (Google, Xiaomi, Netflix, etc.).
• 📥 Install applications again (the list can be exported in advance through Settings) → Annexes → Exports of the list).
• 🎛 Set up sound, picture and other parameters.

💡

Before reset, save important data: screenshots of screen settings, list of installed applications, logins from services, which will save time after the reboot.

Method 5: Cleaning the cache through ADB (for technical users)

If you’re familiar with Android Debug Bridge (ADB), you can clear the cache via the command line.This method is suitable for all Xiaomi TV models on Android TV and allows you to point-to-point memory management.

What you need:

• 🖥 Computer installed ADB (You can download from the official website).
• 🔌 USB-cable (or Wi-Fi connection).
• ⚙ Included debugging by USB on the TV (Settings) → On TV. → Build Number – Press 7 times, then return to Settings → For developers → Debugging by USB).

Cleanup commands:

adb shell pm list packages -f | grep 'cache'


adb shell pm clear --user 0 com.android.tvlauncher # Clearing the launcher cache




adb shell pm clear --user 0 com.google.android.youtube.tv # YouTube Cleanup




adb shell cmd package bg-dexopt-job # Optimization of background processes

To completely clean the cache of all applications, use:

adb shell su -c 'find /data/dalvik-cache -type f -delete'


adb shell su -c 'rm -rf /data/cache'

⚠️ Note: Su commands require root rights, which are disabled on most Xiaomi TVs, and may result in a loss of warranty or failure of the TV!

How to prevent the accumulation of cache in the future

To avoid cleaning the cache too often, follow these tips:

• 🔄 Regularly update the TV firmware (Settings) → Software updates: Memory optimizations in new versions.
• 🗑 Remove unnecessary apps – each one creates a cache, even if you don’t use it.
• 🛑 Limit the background of applications (Settings) → Annexes → Special access → Auto-start).
• 📦 Use external drives (flash drives or flash drives) SSD) for installing applications (Settings) → Warehouse → Preferred installation location).
• 🔍 Check the cache volume once a month through Settings → Memory.

On Xiaomi TV A2 and later, there is a feature called Auto Cleanup, which deletes unnecessary files when memory is scarce, to enable it:

1. Go to Settings → Storage → additionally.
2. Activate the option of automatic garbage cleaning.
3. Set a threshold value (e.g. 500MB of free memory).

If you watch video streaming frequently (like YouTube or Twitch), the cache will accumulate faster.

• 📶 Using wired internet instead of Wi-Fi (reduces buffering and cache volume).
• 🔽 Limiting video quality in application settings (e.g, 720p instead 4K).
