Modern Smart TVs from Xiaomi operate under the operating system Android TV, which, like any computer or smartphone, requires regular maintenance. Over time, the internal storage of the device is filled with temporary files, residual data of remote applications and cache, which inevitably leads to a slowdown in the interface. Users often notice that the menu begins to hang up, and the launch of heavy programs like YouTube or Netflix takes an unreasonable long time.
The main reason for the lack of space lies in the limited amount of internal memory that manufacturers often make minimal (usually 8 or 16 GB), leaving the user even less free space after installing the system. The Android TV system partition can take up to 40% of the total storage, leaving only a small part for user data. When the free space runs out, the TV cannot create temporary clipboard files, which causes critical errors and forced closure of applications.
In this article, we will take a look at all available ways to free up space, from standard system tools to advanced computer cleaning methods. You will learn how to safely remove unnecessary data without damaging the device’s performance, and which tools are best suited for the Xiaomi Mi Box model or embedded Mi TVs. Regular maintenance will extend the life of the gadget and ensure smooth multimedia functions.
Analysis of occupied space in Android TV
Before you start taking radical steps to delete files, you need to do a thorough audit to understand what exactly occupies space, built-in diagnostics allow you to see the distribution of memory between applications, images, video and system data, which helps to identify heavyweights that you may not have used for a long time, but who continue to consume resources.
To get detailed statistics, you should go to the device settings. Navigation through the menu is done using the remote, so it is important to choose carefully. The standard path is: Settings → Device → About TV → Memory. This section shows the total storage capacity, the amount of space occupied and the available balance.
- 📊 Applications – occupy the bulk, especially if games or heavy media players are installed.
- 🗑️ Cache – temporary files that speed up content loading, but over time inflate to gigabytes.
- 📦 System data – operating system files that cannot be deleted without loss of functionality.
Note that some system processes may temporarily take up space to buffer streaming video. If you see memory filling up instantly while you’re watching, it may indicate a memory leak in a particular application, in which case it’s worth checking if the program requires an update or reinstallation.
Clearing cache and data through system settings
The safest and most recommended way to free up space is to use regular tools of the Android operating system. This method does not require the connection of third-party software and eliminates the risk of deleting important system files. Clearing the cache allows you to delete temporary data that accumulate during the use of applications without affecting your personal settings or logins.
To do this, you need to go to the application management menu, and here you'll see the full list of installed software, and you'll want to sort the list by memory size to see if you're looking at the most voracious programs, and it's often found that one or two of the services that are rarely used take up the lion's share of the available volume.
☑️ Cache cleaning algorithm
When you select a specific application, you will see the "Clear Cache" button, which will securely delete temporary files. However, there is also the option "Clear Data" (or "Reset App"). Attention: using this feature will return the application to state immediately after installation, removing all your logins, passwords and personal settings within the program.
⚠️ Note: Do not use the Clear Data feature for system applications such as Settings, Google Play Services or Android TV Core" if you are not sure what you are doing, it can cause a user interface to crash or loss of access to your Google account.
Once you clear the cache of heavy applications like browsers or social media, you can free up a few hundred megabytes to a gigabyte of space, which is often enough to get the TV back to work quickly. If you can't make room with standard methods, move on to specialized software.
Use of specialized cleaning applications
Android TV is not always effective against hidden debris. For deeper cleaning, experts recommend installing specialized utilities from the Google Play Store, which can find residual files, empty folders and duplicates that the average user may not notice when manually searching.
One of the most popular and proven solutions is Files by Google, which has a simple interface adapted to control from the remote, and efficiently analyzes the contents of memory, and Clean Master for Android TV and SD Maid are also well-established, providing more detailed control over the file system.
When using cliners, it is important to be careful with automatic cleanup modes. Some aggressive algorithms may try to delete files that they think are unnecessary but are necessary for certain services to work. Always check the list of files proposed for deletion before confirming an operation.
Why can’t you install too many antiviruses?
After installing the selected utility, run a system scan. The program will analyze the file structure and report. Usually, cleaning takes 1 to 5 minutes depending on the amount of data accumulated. After the procedure is completed, it is recommended to restart the device to apply the changes.
Removing Unused Applications and Games
The most effective way to free up a significant amount of memory is to remove programs you don't use, and many users install apps to try and forget about them, and they continue to hang in memory, taking up space and sometimes running background processes.
You can delete the application through the main menu or through settings. In the application list, find the unwanted program, click on it and select "Delete". If the delete button is inactive (gray), then it is a system application that can not be removed by standard methods without superuser rights (Root).
When removing games, consider that they often take up the most space because of graphics resources. Even if you don't play constantly, having a few heavy games can eat up all your free memory.
| Type of application | Average size | Recommendation |
|---|---|---|
| Streaming services (Netflix, YouTube) | 50 - 150 MB | Leave, clear the cache |
| Heavy 3D games | 1- 4 GB | Remove after passing |
| browsers | 100 - 300 MB | Use one, remove the cache |
| Google System Services | Depends on the version. | Don't remove |
💡
Removing even one large app or game can free up more space than cleaning up your cache for a week with all the tools available.
Connecting external memory and transferring data
If Xiaomi’s internal TV memory is critically small, the solution is to expand storage with external media, and most models have USB ports that can be connected to a flash drive or external hard drive, especially for models with 8GB of internal storage.
After connecting USB-The system will suggest formatting the drive. Choose the use case as "Internal Memory" (if supported by the Android version) or "Universal Drive." In the first case, the system will be able to transfer applications to an external drive, in the second - store only media files there.
The use of external memory has its nuances. USB-The storage device may be lower than the internal memory, which sometimes leads to a slightly longer load of applications. However, for storing movies, music and photos, this is an ideal option that unloads the main system partition.
💡
Use it. USB-interface-storage USB 3.0 (blue connector inside) and fast recording speeds. Cheap flash drives may not be able to handle streaming high-resolution video 4K.
In the storage settings, you can force some applications to an external medium. Go to Settings → Device → Memory, select an application and click Change or Move to USB. This will free up precious megabytes in the internal partition for system needs.
Radical measures: Resetting to factory settings
When neither cleaning the cache nor deleting the apps is working, and the TV is still unstable, the last option is a full system reset, which will return the device to the “out of the box” state, removing absolutely all user data, accounts and settings.
Before starting the procedure, make sure to back up your important data if possible. Remember that after the reset, you will have to reconnect to Wi-Fi, log in to your Google account and re-install all the necessary applications. It is a long process, but it is guaranteed to remove any software debris.
To perform the reset, go to Settings → Device → Reset (or About TV → Reset). The system will warn you that all data will be destroyed. Confirm the action and wait for the process to be completed. The TV will restart and start the initial setup.
⚠️ Attention: During the reset process, it is strictly forbidden to turn off the TV from the socket or pull the power cord. Interrupting the recording of system files can lead to the "bricking" of the device, after which it can be restored only in the service center.
Once you reset successfully, you'll get a clean system with maximum memory. In the first hours of operation, the TV can run slower than usual while the files are indexed and the services are being updated in the background. Give it time and the performance will recover.
