How to turn off the power button on Xiaomi: the full guide

Xiaomi and Redmi smartphones are famous for their functionality, but the standard MIUI or HyperOS shell lacks a native option to completely ignore the on button, which is often a problem for parents whose children constantly turn off the gadget, or for owners who use the phone as a navigator or smart home control panel.

You can't physically disable the button without disassembling the device, which will make you unwarranted, but software methods can completely neutralize its action. In this article, we'll look at how to block the power button through system constraints and third-party software.

There are several levels of locking, from simply stopping the screen from turning off to completely insulating the interface, and the choice of method depends on your ultimate goal, whether it’s child protection or creating a specialized device.

Why block the power button on your smartphone

The main reason users are looking for a way to turn off the click response is the kiosk mode. When the phone turns into a stationary control panel, a random touch should not interrupt the application. Power locking is critical here.

Another scenario is child control, and young children love to press all the buttons available, and if the phone is in the pocket or the hands of the child, one unsuccessful tap can turn the device off or trigger an emergency call.

Also worth mentioning are people with special needs or older users who may accidentally turn off a device while holding it in their hands, in which case limiting the functionality of the buttons increases usability.

Use of the built-in mode "Second space"

The MIUI shell offers a "Second Space" feature that creates an isolated environment, and while it doesn't turn off the power button globally, it allows you to limit the actions within that profile, and that's the first step to creating a safe zone.

To activate, go to Settings → Second Space, where you can create a separate desktop with a limited set of applications, and if a child or user is in that space, leaving requires a password or a fingerprint.

However, even in the second space (long press) or short press of the power button can still trigger the shutdown menu, so this method is only effective when combined with other solutions, such as locking the interface.

⚠️ Warning: The second space is not a full-fledged anti-thief or button blocker, it only separates data and settings.

"Kiosk" mode for business and presentations

For the corporate and retail sectors, Xiaomi offers more advanced solutions: Kiosk Mode allows you to pin one or more apps on the screen, blocking all system buttons, including power.

To activate the basic restrictions, use App Logging. Go to Settings → Passwords and Security → Access device features → App Logging. Turn on the switchboard and follow the instructions.

Once the fix is activated, trying to turn off the phone with the power button will only lock the screen, but not turn off. To exit the mode, you will need to simultaneously press special keys that only the administrator knows about.

This method is ideal for:

• 📱 Payment terminals
• 🗺️ Navigation systems in the car
• 📊 Information panels

Third-party applications for button blocking

If there's not enough system tools, Google Play apps come to the rescue, and the leader in this niche is the Button Mapper app or the specialized "Kiosk Lockdown" programs, which require extended access rights.

These utilities often require an ADB connection, which is not root rights, but access to hidden system settings, and you give the app permission to reassign the buttons.

Popular applications allow you to customize scenarios:

• 🚫 Completely ignoring the short press
• 🚫 Ignoring long pressing (off)
• 🚫 Blocking keyboard combinations (volume) + feeding)

Using third-party software is the only way to completely reassign or disable the power button response without flashing the system, but beware: a poor-quality application can cause a cyclical reboot.

Setup lock through ADB commands

For advanced users who don’t want to put unnecessary background processes, there is a method of direct configuration modification via ADB.

First, turn on USB debugging in the Developer menu. Then connect your smartphone to your PC. Open the command line and type a command to get a list of button-handling packages.

adb shell dumpsys input | grep"mDispatching"

You can then use utilities to reassign keys, such as creating a.keylayout file with modified keycodes, which is a complex technique that requires accuracy, because a code error can make the phone unmanageable.

⚠️ Attention: Improper use of commands ADB This can lead to a device being "bricked" or data loss. Always back up.

Solving problems with sticking and physical defects

Sometimes the question of "how to turn off" arises from a physical breakdown. If the Xiaomi power button is stuck or closes, the phone can indefinitely reboot or shut down. Software shutdown here is a temporary measure.

In such cases, you can try to programmatically prevent the reaction to a long press so that the phone does not turn off on its own, but if the button closes the circuit constantly, the software methods may not work, since the signal interrupts the processor at a low level.

💡

If the power button is physically faulty, turn on the dual tap function in the screen settings, which will allow you to turn on the screen without using the side button.

To diagnose, use button testers, which will show you if the button is sending a signal when you're not touching it, and if the signal is constantly going, you need to replace the plume at the service center.
