Xiaomi Mi TV Cleanup: A Complete Guide for All Models

Xiaomi Mi TVs have become popular thanks to a combination of affordable prices and a powerful hardware platform. However, over time, even the most productive equipment begins to work slower: applications hang up, the system slows down when switching channels, and the interface reacts with a delay. The reason most often lies in clogged cache, overloaded memory or fragmented data. In this article, we will discuss all the ways to clean the Xiaomi Mi TV from basic methods to deep reset, and also explain how to prevent re-clogging of the system.

It's important to understand that cleaning your TV is not just about removing unnecessary files, but also optimizing Android TV, which is the basis for Mi TV firmware. Some users mistakenly believe that it's easy to remove apps, but in fact the system requires a comprehensive approach: cleaning the cache, managing background processes and even hardware reboot. We have collected proven methods that work on all models, from Mi TV 4A to the flagship Mi TV Q2 and Mi TV Master.

Why is the Xiaomi Mi TV starting to slow down?

Before you start cleaning, it’s worth figuring out the reasons for the slowdown. Xiaomi TVs run on a modified version of Android TV, which, like any OS, accumulates “garbage” over time.

• 🗑️ Overflowing application cache are temporary files that should speed up programs but slow down the system when they are too much.
• 📦 Unnecessary background processes – many applications (especially streaming services) continue to run in the background, consuming memory.
• 🔄 Data fragmentation – when files are added/deleted frequently, the TV’s memory is “split” which slows down access to data.
• 📱 Outdated firmware – Older versions of the software may contain errors that affect performance.
• 🎮 Games and heavy applications – even when closed, they leave traces in memory (e.g., Gameloft or emulators).

The problem is particularly severe on low-end models with a small amount of RAM (1-2 GB). For example, the Mi TV 4S 32 with 1 GB of RAM can begin to “suppress” after six months of active use, while the Mi TV Q1E with 3 GB of RAM can withstand the load longer. But even flagships require periodic cleaning – especially if you are actively installing applications from Google Play or third-party sources.

Preparation for cleaning: what to do in advance

Before you start taking action, follow a few preparatory steps to avoid losing important data and speed up the process:

1. Save settings. Take pictures or record current image, sound and network settings (especially if you use custom profiles).
2. Check the firmware version. Go to Settings → About TV → Software version. If an update is available, install it before cleaning.
3. Connect the remote to the Internet. Some operations (such as resets) require confirmation through Mi Account. Make sure the remote is connected to the same Wi-Fi network as the TV.
4. Charging the remote. If you use the Mi Remote Controller with the battery, check its charge - discharging during reset can interrupt the process.

It is also worth considering that deep cleaning (for example, resetting to factory settings) will remove:

• 📺 Installed apps (except pre-loaded ones like Netflix or YouTube).
• 🔑 Google and Xiaomi accounts (re-entry required).
• 📡 Settings for Wi-Fi and connected devices (e.g., sound bar or game consoles).
• 🎨 Individual image and sound profiles.

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

The most gentle method is to clean the cache of individual applications, which will not delete your accounts or settings, but will free up space and speed up the work of programs.

1. Open the settings (cog on the main screen).
2. Go to the Appendix section → All Appendices.
3. Select an app that slows down (like YouTube or IVI).
4. Click Clear Cache (not to be confused with Clear Data – it will delete logins!).
5. Repeat for all "heavy" programs (streaming services, games, browsers).

To speed up the process, you can use the built-in memory manager:

1. Go to Settings. → Warehouse.
2. Select Internal Memory → Cached Data.
3. Confirm the cleanup (the system will show how much space will be vacated).

This method is safe and recommended for monthly maintenance, but it doesn't remove background processes -- it would require rebooting or forcing applications to stop.

💡

If the app is still slowing after cleaning the cache, try reinstalling it. To do this, delete the program, restart the TV and install it again from Google Play.

Method 2: Forced stop of background processes

Many applications continue to run in the background even after they are closed, not only for streaming services, but also for system processes (such as Mi Home for managing smart devices) to stop them:

1. Open Settings → Applications → All applications.
2. Select the app you want (like Prime Video or OKKO).
3. Press Forced Stop.
4. System applications (such as Google Play Services) may need to unlock the Special Options Resolution in the developer settings.

To see which processes consume the most memory:

1. Activate Developer Mode: Go to Settings → About TV and click on the Software Version 7 times.
2. Back to Settings → Additionally. → For developers.
3. Select Services in the Work – here you can see all active processes and their RAM consumption.

⚠️ Warning: Don't stop system processes called android. or com.xiaomi. -- this can cause the TV to run unstable.

Method 3: Deep cleaning through factory reset

If the TV is so slow that even the menu is delayed, it will only help to reset the system completely, and this method will return the system to its original state by deleting all user data.

1. Open Settings → Additional → Reset and Recovery.
2. Select Reset (on some models – Reset factory settings).
3. Enter. PIN-code (by default 0000 or 1234 if you have not changed it).
4. Confirm the action. The TV will restart and start the reset process (5-10 minutes).

After the reset, you will need:

• 🔄 Reconfigure the Wi-Fi connection.
• 📥 Sign in to Google and Xiaomi accounts.
• 📺 Reinstall applications (we recommend starting with the most essential ones).
• 🎨 Set up image and sound profiles to suit your preferences.

⚠️ Warning: On the Mi TV Stick and Mi Box models, reset is done via Settings → Device → Reset. Don't interrupt the process by powering out - this can lead to a "brick" (unable to turn on).

Method 4: Firmware TV to clean the system completely

If the reset doesn't work, or if the TV doesn't turn on after a failed cleaning, you have to reflash the device. This is an extreme measure that requires preparation.

• 🖥️ Computer with Windows/Mac.
• 📁 Official firmware for your model (you can download it on the Xiaomi website).
• 💾 Empty flash drive (FAT32, 32GB).
• 🔌 Cable USB-A → USB-A (for some).

Instructions for firmware via USB:

1. Download the firmware (a file with the.zip extension) and unpack it on a flash drive. The folder should be called update, and the firmware file should be called update.zip.
2. Turn off the TV from the network, insert the flash drive into the USB-port.
3. Press the Menu button on the remote and, holding it, connect the TV to the network.
4. Wait for the recovery menu to appear. Select Apply update from USB → update.zip.
5. After you complete the firmware, select Reboot system now.

For models with a locked bootloader (such as the Mi TV 5 Pro), it may be necessary to unlock through the Mi Unlock Tool, a process that is more complex and requires linking a Xiaomi account to the device.

💡

Fastboot's firmware deletes all data without recovery, and use this method only if other cleanup methods have failed.

Method 5: Optimizing the work after cleaning

After cleaning the TV, it is important to adjust it so that it does not clog again.

• 🚫 Limit background activity: In application settings (Settings → Applications), turn off autorun for unnecessary programs.
• 🔄 Update your firmware regularly: enable automatic updates in Settings → About TV → System Update.
• 🗃️ Use external drives: for movies and games, plug in SSD or a flash drive via USB (especially relevant for models with 8/16GB of memory).
• 🛡️ Install antivirus: for example, Malwarebytes for Android TV (available on Google Play).
• 📊 Monitor Memory: Check occupied space once a month in Settings → Storage.

Also avoid:

• 🎮 Pirate applications (e.g. modified versions of Kodi or Terrarium TV) – these often contain malicious code.
• 🔗 Connecting to questionable Wi-Fi networks (especially in public places) can lead to virus infection.
• 📥 Download files from unverified sources (e.g., torrents via a TV browser).

On models with an Amlogic processor (for example, Mi TV 4A), it is recommended to turn off the interface animation after cleaning. To do this, activate the developer mode and in the Settings section → For developers, set the values of Animation Scale, Transition Animation and Duration of the animator on the Off. - this will speed up the system's response by 20-30%.

Frequent Mistakes and How to Avoid Them

When cleaning Xiaomi Mi TVs, users often make mistakes that lead to even bigger problems.

• 🔌 Power outage during reset — this can make the TV unfit to turn on. Always wait until the process is complete.
• 📁 Using unofficial firmware – custom firmware (like LineageOS) can take you out of warranty and cause driver problems.
• 🔑 Forgotten PIN- code to reset — if you changed the standard PIN (0000) but forgot it, you’ll have to stitch the TV through Fastboot.
• 📱 Reset via remote from another device -- some general-purpose remotes don't support service functions. Use the original Mi Remote.
• 🌐 Clean up without updating the firmware — if the system is outdated, the reset may not work. Update the software first, then clean it.

If the TV is still slow after cleaning, check:

• 📡 Internet connection quality (slow Wi-Fi can slow down streaming apps).
• 🔋 Power supply (use the original power supply, especially for the Mi TV Stick).
• 🌡️ Overheating (if the TV is hot, let it cool for 30 to 60 minutes).
