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

Xiaomi Android TVs or Google TVs slow down over time, with apps loading, video hanging, and the interface reacting with a delay, most often due to cache, fragmented memory, or update conflicts, but before you bring the equipment into the service, try to clean it yourself — it takes 10 to 30 minutes and 80 percent of the time solves the problem.

In this article, you will find 4 proven cleaning methods, from basic cache cleaning to full reset to factory settings. We will break down the nuances for different models — Mi TV 4S, Redmi Smart TV X, Xiaomi TV A Pro and others, and also tell you how to avoid the mistakes that can turn a TV into a brick. If your Xiaomi started to lag after updating or installing new applications, start with the first section. If the problem is deeper, move to radical measures.

Why is Xiaomi TV slowing down and should it be cleaned?

Xiaomi TV performance depends on three key factors: RAM (RAM), internal storage (ROM) and firmware, each of which fails over time:

• 📱 App caches are temporary files that should speed up work, but when overflowing (usually after 1-2 GB) they start to slow down the system. IVI.
• 🗑️ Garbage files — remnants of deleted applications, error logs, failed update downloads, take up to 500-800 MB of “invisible” memory.
• 🔄 Memory fragmentation — where data is scattered all over the storage, and the TV has to "assemble" it into pieces.
• 🐛 Firmware conflicts – after automatic updates, there may be “tails” of old versions that prevent the new system from working stably.

How do you know it's time to clean?

Critical: If a Xiaomi TV gives an error “Not enough memory” when trying to update the firmware, cleaning the cache will not help – you need to delete applications or reset settings. In models with 16 GB of memory (for example, Mi TV 4A 32), there is only ~3-4 GB of free space after installing the system, and it is easy to score with two or three games.

⚠️ Warning: If the Xiaomi TV doesn't turn on or is stuck on the logo, cleaning won't help - it's a sign of damaged firmware. USB service-wise.

Method 1: Clearing the application cache (without data loss)

The safest and fastest method is to delete temporary files. It does not affect personal data (accounts, Wi-Fi settings, saved passwords), but frees up to 1-3 GB of memory. Suitable for all models on Android TV 9.0 and later, including Xiaomi TV Q2 and Redmi Smart TV X55.

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 that slows down (like YouTube or Megogo).
4. Click Clear cache. If the button is inactive, the cache is already empty.
5. For a complete cleanup, repeat for all applications in the list below.

Which apps to clean first:

Clear the YouTube cache | Clear the Netflix cache | Clear the IVI cache | Clear the Kinopoisk cache | Clear the Google Play Store cache-->

If manual cleaning seems to be long, use automatic mode:

1. In Settings, select Storage and Reset → Internal Memory.
2. Click Clear the cache (button at the bottom of the screen).
3. Confirm action. The system will delete the cache of all applications at once.

💡

Once the cache is cleared, the first launches of the applications will be slower than usual — that's OK.

⚠️ Warning: Don't confuse Clear cache and Clear data! The second option will delete all app settings (e.g. logins on Netflix or YouTube history).

Method 2: Remove unnecessary applications and files

If there is still not enough space after cleaning the cache, check which programs are taking up memory. Xiaomi TVs often pre-installed unnecessary services (such as Mi Home for a smart home or games from partners) that cannot be removed in the standard way.

How to make room:

• 📺 Remove User Applications: Go to Settings → Annexes → Installed apps. Select an unnecessary app (e.g. TikTok or Likee). Click Delete (if the button is active).
• 🔧 Disable system applications: Some programs (e.g. Mi Game Center) can't be deleted, but you can disable: In the same menu, select the application. Press Disable (if the button is available). Confirm the action. The application will disappear from the menu, but will remain in memory.

Removal of loads:

Files downloaded through the browser or Google Play Store can take up gigabytes:

1. Open the File Manager (or File Manager) application.
2. Go to the Download or Download folder.
3. Select unnecessary files and click Delete.

Method 3: Resetting settings to factory (complete cleaning)

If Xiaomi TV slows down even after cleaning the cache and removing the applications, the radical method is resetting to factory settings, which will delete all data: accounts, Wi-Fi settings, installed programs, saved passwords.

• 🐢 The TV is so unusable that you can’t use it.
• 🔄 After the update, critical errors appeared (for example, no sound or no remote control).
• 📦 You need to sell/give TV and delete personal information.

What to do after the discharge:

• 🔌 Connect to Wi-Fi again.
• 📥 Sign in to your Google account (if necessary).
• 🎯 Install only the necessary applications (don’t clog up memory!).
• 🔧 Customize the image and sound to suit yourself (brightness, white balance, etc.).

⚠️ Note: On Xiaomi TVs with Google TV (for example, Xiaomi TV A2 43”) after reset, you may need to reset Google Assistant and connect devices to your account again.

Method 4: Cleaning through the service menu (for experienced)

If the standard methods didn't work, and you don't want to reset, you can use the service menu, which is hidden from ordinary users, but allows you to:

• 🧹 Forced to clear Dalvik cache (accelerates the system).
• 🔍 View the error logs.
• 🔄 Restart the TV in Safe Mode (without third-party apps).
• 🧹 Clean the cache once a month: use automatic cleaning in Settings → Warehouse.
• 🚫 Don’t install games: even simple games like Candy Crush take 200-500 MB and load the processor.
• 🔄 Reboot the TV once a week: this clears RAM. To reboot, press the power button on the remote for 5 seconds.
