The situation when the modern Smart TV starts to work slowly, familiar to many owners of Xiaomi equipment. Instead of a smooth interface and instant launch of applications, the user faces delays in pulse, long menu response and spontaneous shutdowns of applications. This is especially disappointing, given that Xiaomi TVs are initially positioned as affordable devices with good characteristics.
The main reason that the Xiaomi Mi TV is dumb is due to the Android TV operating system, which over time becomes overgrown with temporary files, cache and residual data from remote programs, and performance is also affected by the overflow of internal memory and overheating of the processor during prolonged work in the background.
Before you bring a device to a service center or look for a new model, you should do a comprehensive software optimization. In most cases (about 85%) the problem can be solved independently without having deep technical knowledge. Below we will discuss a step-by-step algorithm that will restore your TV sharpness.
Primary diagnosis and verification of compounds
To start troubleshooting, you need to check the physical condition and basic settings. Often users look for software bugs where the problem lies in the banal overheating or poor Wi-Fi signal. If the Xiaomi TV warms, it forcibly reduces the clock speed of the processor to avoid damage to components, which causes the lags.
Make sure the device is installed in a well-ventilated place, the back panel should not fit tightly against the wall, and the ventilation holes should be closed with decorative elements or dust, and check the quality of the Internet connection, as slow loading of content is often mistaken as the brakes of the system itself.
- 📡 Check the Wi-Fi signal level in your network settings and connect the Ethernet cable if necessary.
- 🌡️ Touch the back cover: If it's hot, let the TV cool off when it's off.
- 🔌 Turn off all the extras. USB-Devices (drives, hard drives) that can consume system resources.
An important step is to check for updates. Sometimes the lags are caused by bugs in the current firmware version that developers have already fixed. Go to Settings → Device → System Update and check for a new version of the software.
Cleaning up memory and removing junk files
The most common reason Xiaomi TVs start to slow down is because of overflowing internal memory. Android requires free space to create temporary files and swaps. If free space runs out, the system starts to run critically slow.
To start, use the built-in cleanups. Search the Cleanup app or Storage Cleaner on the TV menu. Run the scan and delete the proposed files. However, the built-in tools often do not remove the cache of third-party apps, which can take up gigabytes.
You should manually go through the list of installed applications. Go to Settings → Apps → All apps. Sort the list by size and remove those programs that you do not use. Pay special attention to heavy online cinemas and games.
☑️ Checklist for memory cleanup
⚠️ Warning: When removing system applications or components that have the word "System" or "Google" in their name, be extremely careful.
If the built-in cleaning isn’t enough, install a dedicated file manager, such as X-plore or File Commander, which can help you find and delete hidden folders with error logs and residual files after remote programs.
Managing Autoboot and Background Processes
Many Android TV apps have an unpleasant habit of running automatically when the TV is turned on and continuing to run in the background, consuming RAM. This is one of the main reasons why the interface responds to latency commands.
The default Android TV settings often have a boot management feature hidden in them, and you can use third-party tools like Sena TV or Background Apps and Process List to solve this problem, which allow you to see the full list of running processes and force them to stop.
| Type of application | Impact on speed | Recommendation |
|---|---|---|
| Online cinemas | High (cache, background services) | Stop after watching |
| Games | Critical (downloading the GPU) | Remove if not used |
| System widgets | Average (constant survey) | Disable in the interface settings |
| Messengers | Low (rare notifications) | We can leave. |
You should also disable automatic app updates in the Google Play Market if you have unstable internet or little memory. Updates are often downloaded and installed in the background, loading the disk subsystem. You can do this in the Play Market settings: Settings → Auto Update Applications → Never.
How to disable unnecessary Xiaomi services?
Resetting to factory settings (Hard Reset)
If memory cleaning and process management fail, a radical but effective method remains: a complete system reset, which will put the Xiaomi TV out of the box by removing all user data, accounts and installed apps.
Before starting the procedure, be sure to save important data, if any, and write down passwords from Wi-Fi and accounts. Reset can be done in two ways: through the settings menu or using buttons on the case (if the TV does not respond to the remote).
To reset via the menu, go to Settings → Device → Reset. The system will request confirmation. After that, the TV will restart and begin the cleaning process, which can take from 5 to 15 minutes.
⚠️ Warning: Once reset, the TV will be completely clean. You'll have to reconfigure your Wi-Fi, log in to your Google account, and install all the apps you need.
💡
Full reset eliminates 99% of software errors caused by configuration conflicts or system files corruption over a long period of operation.
Optimize your network and DNS for quick response
Users often complain that the TV is dumb when watching videos online, even though the menu works fine, in which case the problem is not the processor, but the speed of data acquisition. DNS-ISP servers may be slow or have problems routing to content provider servers.
Change of change DNS-Addresses to faster ones (e.g. Google) DNS Or Cloudflare, which can dramatically speed up video launch and interface response. Go to network settings, select your Wi-Fi or Ethernet connection, go to settings. IP and set up static IP, spelling DNS manually.
Use the following addresses for maximum speed:
- 🌐 DNS 1: 8.8.8.8 (Google)
- 🌐 DNS 2: 1.1.1.1 (Cloudflare)
- 🚀 Alternative: 76.76.2.0 (Control D)
It's also worth checking if your Wi-Fi channel is overloaded by neighborhood routers. If you're using 2.4GHz, switch to 5GHz if your router and TV support that standard, which will provide more stable data transfer and lower ping.
Alternative methods and use of external prefixes
Owners of older Xiaomi TVs (released before 2019-2020) may find that the hardware of the device is simply obsolete, modern versions of YouTube apps and online cinemas are getting heavier every year, and a weak TV processor can no longer cope with decoding video in 4K.
In this case, software optimization will only have a temporary effect. The best solution is to acquire external ones. TV-consoles (for example, based on Android) TV Box or Apple TV). It will take over the entire computing load, and the TV will perform only the function of the monitor.
If you are not ready to buy additional hardware, try installing lightweight versions of apps (Lite versions) or using the built-in browser to view content, although this is less convenient. Also helps to disable unnecessary animations in the developer menu, if you can activate this mode.
💡
Use Image Mode -> User Mode and turn off all color enhancements and noise reduction, which will reduce the load on the video processor when watching regular TV and menus.
