How to turn off the power button on Xiaomi: a complete guide for smartphones and smart tech

The power button on Xiaomi devices is one of the most vulnerable elements: accidental taps in your pocket, children playing with your gadget, or even mechanical damage can lead to undesirable consequences. But what if you need to temporarily or permanently block its functionality? Is it possible without physical intervention?

In this article, we will discuss 5 working methods to turn off the power button on Redmi, POCO, Mi smartphones, as well as on smart watches and TVs of the brand. It is important to understand that completely disabling the hardware button is impossible software — it is about blocking its reaction to presses or reassigning functions. Each method has its own nuances, so carefully read the instructions before using.

Why you might need to turn off the power button

At first glance, the idea of blocking the power button seems strange, but in practice there are several good reasons:

• 👶 Child protection: Toddlers often accidentally turn off their smartphone or start emergency mode by pressing the power button.
• 🔧 Preventing accidental taps: In a pocket or bag, the button may clamp, causing the screen to reset or lock.
• 🛠️ Diagnostics of malfunctions: if the button is ingested or triggered by itself, its temporary shutdown helps to identify the problem.
• 🔒 Security: In some scenarios (e.g., when using the device in kiosks or public places), you need to restrict access to the shutdown.

However, completely disabling the power button at the hardware level is impossible without physical modification of the board. All of the methods described below work at the software level, blocking the system's response to presses. This means that in emergency cases (for example, a device freezes), you will not be able to force the gadget to restart in the standard way.

⚠️ Warning: Disabling the power button can make it harder to access Fastboot or Recovery mode.If you plan to flash your device or perform a setting reset, return the standard button functionality in advance.

Method 1: Use the "No button" mode in MIUI

Starting with MIUI 12, Xiaomi’s firmware has built-in “Buttonless Management” that allows you to reassign the actions of hardware keys. This method does not disable the button completely, but makes it useless for standard functions.

How to activate:

1. Open the Settings. → Special facilities.
2. Select Control without buttons (in some versions – Physical buttons).
3. Activate the slider Turn off the power button or reassign its action to another function (for example, to start the voice assistant).
4. Confirm the changes and restart the device.

This method works on most modern Xiaomi smartphones, including Redmi Note 10/11/12, POCO F3/F4/F5, Mi 11/12/13. However, on devices with MIUI 11 and older, this option may not be available.

Method 2: Reassign the button over ADB (for advanced)

If your MIUI version doesn’t have an integrated option, you can use the Android Debug Bridge (ADB) tool, which requires connecting the device to your computer and basic command line knowledge.

Instructions:

1. Turn on Developer Mode on your smartphone: go to Settings → About Phone and 7 times click on the MIUI version.
2. Return to Settings → Additional → For developers and activate Debugging over USB.
3. Connect the device to the PC, install ADB drivers and execute the command:

adb shell settings put global power_button_behavior 0

This command disables the system's response to short presses of the power button. Use:

adb shell settings put global power_button_behavior 1

⚠️ Note: Some custom firmware may ignore this command. MIUI settings may reset.

💡

If ADB Does not recognize the device, try reinstalling drivers via Mi PC Suite or use an alternative USB-cable.

Method 3: Disable the button on Xiaomi smartwatch (Mi Band, Watch)

On Xiaomi wearables (e.g. Mi Band 6/7, Xiaomi Watch S1/S2), the power button is often combined with the touchpad. You can’t completely turn it off, but you can limit the functionality through the Mi Fitness or Zepp Life app.

Steps for Mi Band:

• 📱 Open the Mi Fitness app and connect to the bracelet.
• 🔧 Go to the Device Profile → Screen settings.
• 🔄 Turn off the option to touch the button (in some versions – Quick turn on).
• 🔒 Set a password to unlock to prevent accidental clicks.

The algorithm is similar for the Xiaomi Watch, but the path may be different: Settings → Screen and brightness → Button management. Note that on some models (for example, the Watch S1 Pro), the power button is also responsible for starting workouts - turning it off can affect functionality.

Method 4: Blocking a button on Mi TVs

On Xiaomi TVs (Mi TV 4/5, Redmi TV series), the power button on the remote or the case can also be blocked, but only indirectly through restricting access to settings.

Options for action:

• 🔐 Parental Control: Establish a Parental Control PIN-code for changing settings in Settings → Security → Parental control. This won't turn off the button, but it will block access to the shutdown through the menu.
• 📶 Removing the remote from memory: in Settings → DU remote → Control of remotes can be removed pairing standard remote, leaving only the alternative (for example, through Mi Home).
• 🔌 Disabling the physical button: on some models (e.g. Mi) TV Q1) button on the body is connected through a separate plume - it can be carefully disconnected (disassembly is required!).

To completely turn off the power button on the TV will require firmware with a modified PatchROM, but this is risky and lacks warranty.

Method 5: Physical lockdown (for emergencies)

If software methods are not suitable, you can resort to mechanical locking, which is relevant for devices that are rarely turned off (for example, kiosks or media players).

Implementation options:

• 🛡️ Lock case: some protective covers (for example, for POCO X3 Redmi Note 10 has cutouts that can be closed with a plastic insert.

⚠️ Note: Physical locking can damage the button or the case. If you are not sure about your skills, contact the service center. Also remember that after such an intervention, the Xiaomi warranty will be canceled.

Frequent Mistakes and How to Avoid Them

When trying to turn off the power button, users often face some common problems, and here are the most common ones and ways to solve them:

Another common mistake is to ignore alternative ways of turning on, so before you lock the power button, make sure you can turn on the device by other methods:

• 🔌 Connecting a charger (works on most Xiaomi smartphones).
• 🖱️ Through OTG-mouse or keyboard (if support is enabled) USB OTG).
• 📡 Through a network team (for TVs with Mi Home).

💡

Before you turn off the power button, always check how you turn on the device in case of emergency.
