Owners of modern Xiaomi Mi TVs often face a situation where after several months of active operation, the device starts to work slower, the interface freezes, applications open with a delay, and sometimes even fly out at launch, these are classic signs of overflowing system storage with temporary files that accumulate during the use of streaming services and games.
The Android TV system that runs Xiaomi TVs is designed just like a smartphone: it stores data to quickly load content. However, over time, this mechanism fails, and instead of speeding up the cache begins to slow down the processor. Regular cleaning of this data is not just a recommendation, but a necessary procedure to maintain the stability of the Smart TV.
In this guide, we’ll take a look at all the ways you can delete temporary files, from built-in system tools to advanced computer-based methods, and learn to distinguish important data from junk and safely free up space without risking losing your settings or subscriptions.
What is Cache and Why Does It Slow Down TV?
Cache is a region of RAM or permanent memory that is designed to store intermediate data that can be accessed quickly. In the context of Xiaomi TVs, these are video preview files, application temporal logs, image thumbnails and snippets of web pages. When you first launch YouTube or Netflix, the system loads heavy interface elements and stores them locally.
The problem arises when the volume of such files becomes too large or when corrupted data enters the storage. Instead of reading the finished information, the Android TV processor spends resources checking the integrity of the cache or trying to read the broken sectors, which leads to the fact that even a powerful Xiaomi Mi TV Stick or 4S TV begins to stutter when scrolling the menu.
It is important to understand the difference between cache and application data: Cache removal is safe and often solves performance problems, while data deletion resets the application to the “just established” state, requiring re-entering passwords and settings.
⚠️ Warning: Don't confuse cache cleaning with full setup reset.Cache cleaning removes only temporary debris, saving your accounts and installed programs.
The accumulation of junk files is particularly common in applications that actively use streaming video. Services like Ivi, Okko or Kinopoisk can take up gigabytes of space in a few weeks of viewing. If you do not control this process, the free space in the Memory section is rapidly shrinking, which critically affects the performance of the entire system.
Standard cleaning through Android TV system settings
The safest and most recommended way to free up space is to use the built-in functionality of the operating system. TV On TVs, Xiaomi provides access to memory management without the need to install third-party software. TV P1 older versions.
You first go to the main menu and find the settings section, and the way to do that is usually to click on the remote button with the gear or select Settings in the upper right corner of the screen, and then the system will suggest you go to the deep settings of the system.
💡
If the TV interface is severely inhibited, try cleaning immediately after turning on before the background processes have fully booted.
The settings menu will be a section that you're interested in, which is related to application management. Depending on the version of Xiaomi's firmware, it can be called Apps, All Apps, or Application Management, and here's a complete list of installed software, sorted by frequency of use or size.
Choose the application that consumes the most resources (often browsers or video players). Inside the application menu, you will see two important buttons: Clear the cache and Clear the data. To solve speed problems, just press the first button. The system will instantly delete temporary files, freeing up space.
☑️ Procedure in settings
Repeat the procedure for all resource-intensive programs. Pay special attention to the Google Play Services system application and the built-in browser if you use them. They tend to grow to unimaginable sizes, taking up to 500 MB or more of temporary storage.
Use of built-in cleaner and service menu
Some versions of the PatchWall shell or Xiaomi's Android TV include a built-in optimization tool that allows you to do a comprehensive cleaning with a single click, and you can find it by pressing the Home button on the remote or through a special TV Manager app.
Accelerate or Clean up analyzes the current state of RAM and internal storage, forcibly shuts down background processes that are not currently in use, and removes temporary files from system folders, which is especially useful if the TV is slowing down while watching video.
However, it is worth considering that automatic cleaners do not always work perfectly, they can leave "tails" in the form of error logs or a cache of updates. Therefore, manual control through application settings described above remains a more reliable method of deep cleaning.
| Cleaning method | Security | Efficiency | Difficulty |
|---|---|---|---|
| Application settings | Tall. | Tall. | Low. |
| Built-in accelerator | Tall. | Medium | Low. |
| Third-party annexes | Medium | Tall. | Medium |
| ADB (via PC) | Low * | Maximum | Tall. |
* Low security of ADB means the risk of deleting system files when incorrect commands are used.
Regular use of built-in service extends the life of your TV flash memory. Constant recording and overwriting of files causes wear and tear on memory cells, so removing excess debris is also a concern for the hardware of your Xiaomi TV.
Third-party applications for cleaning memory on Xiaomi TV
If standard tools are not enough, you can use specialized software from the Google Play Store. There are many utilities designed specifically for Android platforms, which are able to find hidden caches, remnants of remote programs and duplicate files.
One of the most popular and proven solutions is the TV Cleaner app, or Clean Master for Android TV, which, once installed and launched, offers scanning, shows how much space the cache takes up, and allows you to delete it with a single click.
The advantage of third-party utilities is automation, you can set a schedule so that you clean it every night, for example, and it eliminates the need to manually check each application, and some of them can cool applications without letting them run in the background without you knowing.
⚠️ Warning: Be careful of antivirus and accelerator apps from unknown developers, some of which may consume a lot of resources and display intrusive ads.
When choosing a program, pay attention to the rating and installation number. Xiaomi TVs are best suited versions marked for Android TV, as they have an adapted interface for remote control. Conventional mobile versions may require mouse control, which is inconvenient without additional devices.
Radical measures: complete discharge and clean-up through ADB
In situations where the Xiaomi TV is hanging dead and the menu is not responsive to remote commands, a deeper intervention may be required. If the system does not allow you to enter the settings, the only way out is to reset to factory settings (Factory Reset).
To do this, the TV body (usually on the back or side) has a Power button or a special joystick. When the TV is turned off (or when it is getting stuck), you need to pinch this button and, without letting go, turn the device into the socket or press the power button on the remote, hold the button until the Mi logo or recovery menu appears.
For advanced users, there is a method of cleaning through debugging by USB (ADB). Connecting the TV to the computer via a network or USB-cable, you can send commands to remove the cache of system partitions that are not available through the normal interface.
adb shell pm clear com.google.android.youtube
adb shell pm clear com.android.browserThis command will completely clear the cache and data of the specified application (in the example of YouTube), which is a powerful tool, but you need to use it with caution. Incorrect removal of system packages can lead to the failure of the TV.

Preventing: How to Avoid Overflowing Memory in the Future
To avoid going back to cleaning too often, you should change your smart TV habits. First of all, don't install apps just in case. Every app you install, even if you don't use it, can have background services that collect data and take up space.
Check the installed software list regularly. If you watched a movie through an app you no longer plan to use, you better delete it. In the Google Play store on your TV, you can select My apps and uninstall the unwanted ones.
It's also recommended that you turn off automatic app updates at night if you have a TV with a small amount of storage. Updates take up space during download and installation. Do this manually for important programs.
💡
The main rule of prevention: keep free at least 15-20% of the total internal memory of the TV for stable operation of the system.
Watch what permissions you give to applications. If a simple player requests access to a microphone or geolocation, it's suspicious.
