How to turn off Xiaomi smartphone if the power button is broken

When the physical Power button on Xiaomi’s smartphone stops responding to presses, it can take the user by surprise.It’s not just an inconvenience of not being able to lock the screen, but also a potential problem if the device is getting stuck or requires an emergency reboot.Redmi and Poco models often face mechanical wear of the keys due to active use.

Fortunately, the Android operating system and the MIUI shell (or HyperOS) provide a lot of software-based power management techniques. You don't have to bring it to the service center right away just to turn it off. There are several proven action algorithms that can help solve the problem software.

In this guide, we will go through all the available ways in detail, from standard menus to advanced debugging tools. The fastest way to turn off Xiaomi without a button is to use the screen lock feature in the notification curtain or voice assistant. Let’s take a look at each option in detail so you can choose the most suitable for your situation.

Use of the settings menu and notification curtains

The most obvious, but often forgotten, method is to use a regular system interface, which in most modern versions of MIUI, developers have hidden the off button in the settings menu or made it available through the control panel, a basic layer that does not require additional software.

To start, try unlocking the screen and find the Settings app shortcut. Scroll down to the bottom of the list where system settings are usually located. There you will find the About phone item or a separate Turn off button that duplicates the physical key function, and clicking on it will trigger a standard action dialog box.

The alternative and faster way is to use a notification curtain. Swipe down to open the control center. Quick access icons often include a Lock or Turn off button. If it's not on the first screen, click on the pencil (edit) and add this widget to the active zone.

It is important to note that some versions of the firmware may appear in the Google Assistant menu instead of the off menu when the power button is pressed for a long time, in which case the software methods through the settings become the only correct solution. Don't try to push the button too hard so as not to damage the plume completely.

Reboot with Recovery Mode

If the system interface is completely unavailable or the phone is frozen, Recovery Mode comes to the rescue. This is a low-level menu built into the firmware that allows you to control the device even when the touchscreen is not working (manage volume buttons, if they are good) or programmatically through a reboot.

To get into this menu without a power button, you can use the command via a computer or special emulator apps on the phone itself, if you have access to the system. However, the classic method of logging into Xiaomi often requires a key combination. If the power button does not work at all, this method can be difficult, but it is worth trying a software call through ADB (which will be discussed below) or using the reboot menu.

Once you're in the Recovery menu, you'll see a list of options in English. Use the volume buttons to move up and down. You'll need to select Power off or Shutdown. Selection confirmation is usually also done with a power button, but on some Xiaomi models, confirmation is automatically made a few seconds after selection, or you can try pressing the volume button.

• 📱 Recovery is an independent partition of memory that is loaded to the main system.
• 🔧 If the touchscreen does not work, navigation in Recovery is carried out exclusively by mechanical buttons.
• ⚠️ Note: Do not select Wipe Data unless you want to completely erase all data from your phone.

This is a useful method when the system is unstable, but if you just need to turn off your phone to save power, you'd better use a more gentle method. Recovery Mode is a tool for emergency and resetting.

Shutting down via computer and ADB

For advanced users who have an ADB (Android Debug Bridge) toolkit installed on their computer, it allows you to have full control of your smartphone. This method requires that you turn on USB debugging beforehand. If this option is activated before the button breaks, you can control power using the command line.

Connect your smartphone to your PC through USB-Open the command line (CMD) or terminal in a folder with installed ADB. Enter a command to check the connection:

adb devices

If your device is listed as device, the connection is established. To turn off the smartphone, use the command:

adb shell reboot -p

This command initiates the Power Off process. Alternatively, you can use the adb shell svc power shutdown command on some versions of Android. This is the most reliable way, since it runs at the core level and ignores the state of the interface.

💡

Make sure that ADB drivers are installed on your computer, otherwise the PC will not see the smartphone in debugging mode.

If the standard command fails, you can try sending the system switch off key:

adb shell input keyevent 26

However, this command emulates a short press of the power button, which can simply lock the screen rather than turn off the phone. To ensure shutdown, use the command reboot -p. This is a professional method often used by engineers when testing devices.

Emulator applications and virtual buttons

There are many apps in the Google Play and GetApps store that create a virtual floating button on the screen, and utilities like Assistive Touch or Virtual Button allow you to add a button to the screen that mimics Home, Back and, most importantly, Power.

Once you install an app like this, you'll see a translucent joystick or button on the screen, and when you click on it, you'll open a menu where you can choose to turn off or restart, which is ideal if the power button stops working suddenly and you need to unlock your phone or shut it down.

Some applications require special permissions, such as Overlay (above other windows) and access to system functions. Without these permissions, the emulator will not be able to call the shutdown menu. Be careful when choosing an application: read reviews so as not to install malicious software masquerading as a useful utility.

Using third-party software is a temporary solution, it consumes RAM and battery power, and once you fix the physical button or replace the device, it's best to remove those apps so you don't slow down the system.

Use of voice assistant

Xiaomi smartphone owners have access to Google Assistant or Xiao AI (depending on the firmware region) voice control allows you to execute commands without touching the screen or buttons, making this method indispensable when breaking keys.

To turn off the phone, just say, "OK, Google, turn off the phone," or "Hey Google, power off." The system recognizes the command and will give you a confirmation on the screen. You just have to press "OK" on the touchscreen. If the touchscreen is also intermittent, you can try setting up voice confirmation, although this is less common.

To activate the assistant, you usually need to say a phrase or keep the home button long (if virtual), you can turn on the Continued Conversation feature in the Google Assistant settings, which will make it easier to interact, and the assistant can also execute commands “Reboot”, which sometimes works faster than a direct shutdown.

⚠️ Warning: Voice command may not work if the phone is in Do Not Disturb mode or if the microphone is locked by security in sleep mode. Also make sure there is an internet connection to handle the request by the server.

It's a great way to be versatile, it doesn't require any additional software, and it works at the service level, and if the voice assistant doesn't turn off the phone completely, try the "Reboot" command, which often has a higher execution priority.

Automation of shutdown on schedule

The Android operating system has a built-in automatic on and off schedule feature, ideal for those who want to turn off their phone at night or at a certain time without using a physical button.

To set up this feature, go to Settings → Battery and Performance (or simply Battery). Find Scheduled power on/off. Activate the switch and set a time when the phone should turn off. You can set the repetition for certain days of the week.

This function works even in sleep mode, because it's the task scheduler that's responsible for it. You don't have to keep the screen on. Just set a time, say, 5 minutes from now, and the phone will shut down.

Using a scheduler is a lazy, but effective way, and it doesn't require any action from the user when it's off, and the only downside is waiting for the set time.

Hardware causes and prevention

If software methods help, but the button never worked, it's likely the hardware that's the problem, most often the microswitch itself (called the pill) fails, or the plume that connects the button to the motherboard departs. In Xiaomi smartphones with a side-fingerprint scanner, the power button has a complex design, which increases the risk of failure.

A common cause is moisture or dust falling under the key. Even a drop of sweat or sweet soda can oxidize the contacts. In such cases, the button may stick or stop closing the chain. Mechanical wear and tear occurs after thousands of cycles of pressing, which is typical for devices that have been in active use for more than two years.

• 💧 Moisture is the main enemy of electronics, causing corrosion of button contacts.
• 🔨 The impacts can displace the mechanism of the button or damage the plume inside the body.
• 🔋 Bloating the battery can create internal pressure by clamping a button or shifting the boards.

For prevention, it is recommended to use protective covers with protruding sides that take the load on themselves. Do not push the button with excessive effort. If you notice that the button has become stiff or stalled, it is better to immediately use software methods of shutting down and plan repairs.

⚠️ Warning: Attempting to repair yourself without experience can damage the plumes of the screen or battery. If the phone is warranty, any opening of the case will invalidate it.

A temporary solution to protect against accidental pressing (if the button, on the contrary, closes itself) may be to turn off the “Block in the pocket” function in the settings, but this will not solve the problem of turning off. In the case of hardware failure, the only correct solution is to replace the button module in the authorized service.

💡

Software shutdown methods are a temporary solution. If the power button physically breaks, it is recommended to contact the service center as soon as possible to replace the part, to avoid a situation where the phone will run out and you will not be able to turn it on.
