Modern smart TVs like Xiaomi Mi TV or Redmi Smart TV are equipped with Android TV, making their control process different from classic models. Users often face a situation where a short press of the power button does not turn off the screen, but only puts the device in standby mode or starts the voice assistant. Understanding the logic of the MIUI TV interface is critical for comfortable operation.
In this article, we will discuss all the ways to properly shut down the device, we will look at the differences between Standby modes and full shutdown, and also explain how to set up an automatic shutdown timer, which will help to extend the life of the matrix and save electricity without unnecessary actions.
Many owners mistakenly believe that their remote is faulty if the TV doesn't respond to a single tap. In fact, Xiaomi has implemented several levels of power management, and once you understand them, you can flexibly control your device using both standard buttons and voice commands.
Standard method of switching off via the power menu
The most common way to complete a Xiaomi smart TV requires a sequence of actions, not a single tap. Unlike older button models, it uses a software menu. You need to find a button with the power icon on the Mi Remote remote.
If you just press that button, you'll see a horizontal menu with a few options on the screen, including Turn Off, Reset, and Sleep Mode, and then you'll need to use the navigation buttons to select Turn Off and confirm the action, and then the screen will go out and the indicator will go into standby mode.
⚠️ Note: If you just briefly press the power button and don’t select a menu item, the TV can go to Standby, continuing to consume electricity for background processes.
Pressing the power button (more than 3-5 seconds) on some versions of Android TV firmware can also trigger this menu, a useful quick access feature if the cursor is getting stuck on the screen.
💡
A short tap calls the menu, the option “Switch off” completes the system, transferring the TV to deep sleep.
Using a voice assistant to manage
Xiaomi’s next-generation remote controls feature a built-in microphone and support for Google Assistant, which allows you to control your TV without having to look for buttons on the screen. To activate the feature, you need to press and hold the microphone button or the colored Google button.
Once you have an audio signal or a visual indicator on the screen, clearly say the command. The system recognizes the speech and performs the action. The most effective commands to turn off include the phrases "Switch off the TV," "Turn off TV," or "Ok Google, turn off," which is especially convenient when the remote is far away or in the dark.
- 🗣️ Press the microphone button and say, Turn off the TV».
- 🗣️ Use the “Ok Google” command, then “Switch off” command».
- 🗣️ To go to sleep, say: “Sleep mode».
Voice control works even when the system interface is slow to respond, making it a reliable emergency control tool, but to function, the TV must be connected to the Internet, because the request is processed on servers.
Setting up a sleep timer and automatic shutdown
One of the most useful features for energy saving and matrix protection is a sleep timer, which allows you to set up an automatic TV shutdown after a given period of time, ideal for those who like to fall asleep to the noise of video or music.
To set the timer, go to the system settings menu. You'll need Settings → Preferences → Energy & Environment → Sleep Timer. You can choose between 15 minutes and a few hours, and after the time has expired, the TV will shut down on its own.
What happens when the timer expires?
In addition to the manual timer, MIUI TV has a "No Activity" feature, which means that if you walk away with the static screen on, after a given time (usually 10-30 minutes), the TV will ask if you're still watching, and if you don't respond, it will turn off, which prevents pixels from burning out and saving energy.
| Function | Description of action | Where to find out. |
|---|---|---|
| Sleep timer | Shutdown after a predetermined time | Settings → Energy |
| Inaction | Reaction to the lack of remotes | Settings → General |
| Schedule | Time-on/off switching | Settings → Timers |
Remote control via smartphone
If the remote is lost, discharged or defective, you can turn off the TV using your smartphone. Both devices must be on the same Wi-Fi network. Xiaomi provides the official Mi Remote app (for phones with an infrared port) or control through the Google Home app and Android TV Remote Control.
When you use an infrared port, the phone emulates the signal of a conventional remote, so you just have to start the app, select the model of the TV, and press the virtual power button, and this method works even without an Internet connection, because it uses a direct radio channel.
If your phone doesn't have an IR port, use the Google Home app. Find your Chromecast built-in or Android TV on the device list. The control menu that opens will have a shutdown button. This is a convenient way to do it if the physical remote is out of reach.
Power consumption modes: Standby and full shutdown
It is important to distinguish between “turn off” and “sleep down.” In modern Xiaomi TVs with Android operating system, these states have different technical characteristics. Understanding the difference will help you to properly operate the device.
Standby mode leaves the system partially active, in which the TV can continue to download updates, receive commands from the remote or smartphone, and perform background tasks. The indicator is lit red or flashing. The power consumption in this mode is from 0.5 to 3 watts.
⚠️ Warning: In standby mode, the TV can heat up and make noise due to internal processes, which does not happen when completely switched off through the software menu.
Complete shutdown via Settings → Shutdown closes all operating system processes. The device goes into a state close to disconnection from the network, but retains the ability to react to the power button. For complete safety and economy (0W), it is recommended to use a physical switch on the case or pull the plug from the outlet if the TV is not planned to be used for a long time.
Solving problems with the remote and power button
There are times when the TV doesn't respond to shutdown commands, it can be caused by the Android TV operating system freezing or the batteries being discharged. If the screen is black but the light is on, try a forced reboot.
To do this, press the power button on the TV body (usually it is on the back or bottom, under the logo) for 10-15 seconds. The device must vibrate or blink the indicator, after which it will reboot. This is the analogue of a hard reset for a smartphone.
☑️ Diagnostics of the remote
If the remote is no longer fully responsive, check the batteries. Even if the LED on the remote lights up, the charge may not be enough to transmit the IR signal over a distance, and it is also worth checking whether the IR receiver on the TV is closed with foreign objects or a sound bar.
💡
If the remote stops working, try to remove the batteries for 1 minute, then insert them back - this will reset the remote controller and fix software failures.
