Autoshutting Xiaomi: how to turn off on TV and smartphone

Are you tired of your Xiaomi spontaneously turning off at the most inopportune moment? Auto-shutting can be useful for saving energy, but often it works inappropriately - while watching a movie, playing or downloading files. In this article, we will discuss all the ways to turn off automatic shutdown on Xiaomi devices, including Mi TVs, smartphones with MIUI and even smart lamps.

The problem of auto-switching can be manifested in many ways, from a scheduled timer shutdown to sudden reboots due to overheating or software errors. We will consider not only standard settings, but also hidden parameters that the manufacturer does not advertise. It is important to understand that on some devices the auto-switch function can be tied to energy saving mode or parental control - we will talk about this too.

If you own a Xiaomi Mi TV 4S/5/5X/Q1/Q2 or a smartphone with MIUI 12/13/14, you will find the current instructions here, taking into account the latest firmware updates. For owners of Android TV devices (such as the Mi Box), there are also separate recommendations.

1.How to turn off auto-switch on Xiaomi Mi TV

Xiaomi TVs often turn off automatically due to power saving or sleep timer settings. To fix this, you need to go to system settings. On most models (Mi TV 4A, 4S, 5, Q1, Q2, A2), the path to settings is the same, but there may be slight differences depending on the PatchWall version.

First, check your sleep timer, which is the most obvious reason for auto-turning off, and if the timer is not set but the TV is still off, the problem may lie in the Eco Mode settings or Auto-Disabled Inactivity settings. Here's a step-by-step instruction:

• 📺 Open Settings (cog in the upper right corner of the main screen).
• ⏰ Go to System and Updates → Timer.
• ❌ Turn off the sleep timer option (set off).
• 🔄 If the problem persists, go back to Settings → Display & Sound → Eco Mode and deactivate it.

Some models (e.g. Mi TV Q1 75) have a hidden setting to turn off auto-turning when no signal is available, which is activated if the TV does not receive a video signal within 15-30 minutes, to turn it off:

1. Press the Menu button on the remote for 5 seconds to open the engineering menu.
2. Select Factory Settings → Power Off Options.
3. Find the No Signal Power Off option and install Disable.

⚠️ Warning: On Xiaomi TVs with firmware older than 2021, an auto-shutdown may be triggered due to an error in the CEC Control module. If the problem persists after all timers are turned off, try disabling HDMI-CEC in Connection settings → HDMI.

Auto Shutdown on Xiaomi smartphones: causes and solutions

On Xiaomi smartphones (Redmi, POCO, Mi series) auto-shutdown can occur for several reasons:

1. Sleep timer in energy saving settings.
2. Overheating of the processor (especially on the POCO F3, Redmi Note 10 Pro).
3. Firmware error (often found on MIUI 12.5 and MIUI 13)
4. A battery with a low charge level (less than 5%).

First, check the obvious settings. Go to Settings → Battery and Performance → Sleep Timer and turn it off. If overheating is a problem, try the following steps:

• 🔥 Install the CPU Monitor app from Google Play to track the processor temperature.
• 🧊 Clear the cache in Settings → Storage → Cleanup.
• 🔄 Turn off Ultra-Economic Mode in the battery settings.
• 🛠️ If the phone turns off at 20-30% charge, calibration of the battery is required (instruction below).

On some models (Redmi 9, POCO X3), the auto-shutdown may be due to the Security application.

1. Open Security → Battery → Battery settings.
2. Turn off the option Automatic Shutdown at low charge.
3. Add problematic apps (e.g. YouTube, Netflix) to the Exceptions.

3. Hidden settings: disable auto-switch off via ADB

If standard methods don't work, you can use the ADB debugging bridge (Android Debug Bridge), which is suitable for power users and requires connecting a smartphone to a computer, and the advantage of the method is that it allows you to disable system constraints that are not visible in the conventional interface.

To start, turn on the Developer Mode:

1. Go to Settings. → The phone.
2. Click 7 times on the MIUI version until you become a developer!
3. Back to Settings → Additionally. → For developers.
4. Activate Debugging on USB.

Now connect your phone to your PC and execute commands in the terminal (or Command Prompt):

adb shell settings put global stay_on_while_plugged_in 3


adb shell settings put global auto_shutdown_enabled 0

The first command turns off auto-switching when you connect to charging, the second command completely deactivates the system timer. If after the reset, the settings are reset, use this command for continuous application:

adb shell cmd device_config put battery auto_shutdown_disabled true

⚠️ Warning: Changing system settings through ADB may cause the device to operate unstable. Before executing commands, back up your data via Settings → Additional → Backup and Reset.

💡

If the ADB commands still turn off the phone, check the logs of system errors through the Logcat Extreme app, perhaps the problem is in conflict with the custom core or Magisk modules.

4. Auto-Switch off Xiaomi Smart Lamps and Devices (Mi Home)

Xiaomi Yeelight smart bulbs, Mi Smart Plug outlets, and other Mi Home ecosystem devices can also turn off automatically, usually due to settings in the Mi Home app or automation scenarios, to turn off auto-switching:

• 💡 Open the Mi Home app and select the device you want.
• ⏱️ Go to Device Settings → Timers and delete all active tasks.
• 🤖 Check Automation – it may have a time or condition set-up (e.g., no movement).
• 🔄 Update the device’s firmware through Settings → Update.

Yeelight smart bulbs have a separate Sleep Mode feature that gradually decreases the brightness before turning it off.

1. In the Mi Home app, select the lamp.
2. Press... → Lamp settings → Modes.
3. Turn off Sleep Mode and Auto Off.

If the device is turned off due to loss of communication with the router, check the settings of the Mi Home Hub (gateway). Sometimes changing the region in the settings of the application (for example, from China to Russia), as some firmware has restrictions on the time of operation.

Calibration of the battery during false auto-switching

If your Xiaomi shuts down at 20-30% charge, the problem may be incorrect battery calibration.This is common on smartphones older than 2 years or after a battery change.

Here's how to do it:

1. Discharge the phone before it is completely switched off (0%).
2. Connect to the original charger and charge for at least 8 hours without interruption.
3. After full charging, turn off the cable and turn on the phone.
4. Repeat the discharge / charge cycle 2 more times.

To speed up the process, you can use the engineering menu:

#4636## → Battery → Reset statistics

If calibration doesn’t work, check battery wear through the AccuBattery app. If you wear more than 50%, it is recommended to replace the battery. Some models (Redmi Note 8 Pro, Mi 9) require the controller to be reset via Fastboot after the battery is replaced:

fastboot oem reset_battery

6. Updating the firmware as a solution to the problem of auto-switching

Often auto-shutdown is associated with firmware bugs. For example, MIUI 12.5 had an error that caused the POCO X3 NFC and Redmi Note 9 phones to spontaneously reboot at low charge. In MIUI 13, a similar problem was observed on the Xiaomi 11T due to a conflict with the Thermal Engine module.

To update the firmware:

• 📱 Go to Settings. → The phone. → Updating the system.
• 🔍 Click Check Updates and install the latest version.
• 🔄 If the OTA- update doesn't come, download the firmware manually from en.miui.com and install through the Update → Three Dots → Select a file.

For Xiaomi TVs, the firmware update is available through:

1. Settings → About TV → Updating the system.
2. If the automatic update does not work, download the.zip file for your model from the official website and install via USB.

⚠️ Warning: When you manually install firmware on Xiaomi TVs, don't interrupt the upgrade process. If the progress indicator is 99 percent getting stuck, wait at least 30 minutes - that's normal for models on Amlogic chipsets.

7. Alternative methods: firmware rollback and custom solutions

If the auto-shutdown started after the firmware update, you can try to roll back to the previous version. For smartphones, this is done via Fastboot or TWRP. For TVs, you will need a special Mi TV Assistant tool.

Instructions for smartphones:

1. Download the archive with the desired version of MIUI (for example, from xiaomifirmwareupdater.com).
2. Unpack the flash_all.bat file (for Windows) or use fastboot manually:

fastboot flash boot boot.img


fastboot flash system system.img




fastboot flash vendor vendor.img




fastboot reboot

For TVs:

• 🖥️ Install Mi TV Assistant on PC.
• 📁 Download the firmware for your model (e.g. msp40_qq3c_user_20230920.zip).
• 🔌 Connect the TV to your PC via USB and follow the program instructions.

If you use custom firmware (LineageOS, Pixel Experience), the problem may be in the wrong build. Check the logs through adb logcat or contact the firmware developer.

💡

Firmware rollback is a last resort. Be sure to back up the data before the procedure, as all settings and files will be erased.
