How to turn on Xiaomi phone if the power button breaks: the complete guide

When a Xiaomi, Redmi or POCO smartphone stops working, the physical power button catches the user by surprise: the screen goes out, the device goes into sleep mode, and the usual short press no longer leads to the desired result. This is a common hardware problem that often occurs due to wear of the mechanism, moisture or dust entering the body.

But don’t panic too soon, as the Android operating system and the MIUI or HyperOS shell provide several software and hardware workarounds. In this article, we’ll go into detail on all the ways you can start a device, from simple keyboard combinations to using specialized software on your computer, and you can restore functionality even without visiting a service center.

Before we go to radical measures, we need to check whether the problem is mechanical failure. Sometimes the button just gets stuck or contaminated, which interferes with contact. Careful but confident pressing at different points of the key or a slight vibration of the device can temporarily restore sensitivity. If mechanical action does not help, you will have to use software crutches.

⚠️ Note: If the device is completely discharged, some software methods may not work until the first power supply.Make sure the battery has at least a minimum charge before trying complex instructions.

Use of charger and PC

The most common, but often ignored, way to launch a smartphone with a broken button is to connect to a power source. When you connect a Xiaomi switched off to the original charging cable, the power controller automatically initiates the charging process. On many models with a MIUI shell, this action not only displays the battery indicator, but can fully activate the system.

To increase the effectiveness of this method, try to connect the phone not to the network outlet, but to the computer through the USB-When connecting to a PC, the phone receives a signal to connect to a digital device, which sometimes causes the system to wake up more actively than with a normal charge from the network. ID or fingerprint unlocking.

If a simple connection doesn't work, use the power interpenetration method. Connect the cable to the phone that's turned off, then quickly remove it and re-insert it. Repeat this procedure 3-5 times. This simulated unstable contact can trigger the power controller to start the system in emergency mode. This does not work on all models, but is a safe first step.

💡

Use a quality cable with thick veins – poor contact may not transmit the necessary current pulse to wake up the power controller.

Keyboards and login to Recovery Mode

If standard powering is not possible, try using other physical buttons that have remained working. Most Redmi and Xiaomi smartphones have the option of entering Recovery Mode without using the Power button.

Once the Recovery menu appears on the screen (usually a black screen with text or a MIUI logo), try to find the option "Reboot" or "Restart" Navigation in this menu is done with volume keys, and the choice is made by a short press of the same button that you entered the mode (most often Volume Up).

In some cases, the Volume Down + Power combination helps, but since the power button doesn't work, this method is modified. Try to pinch Volume Down and plug in the cable. This can trigger Fastboot mode. While in Fastboot, use the key combination to exit (usually a long hold on the off button that we can't press, or select the menu item through volume if the interface allows).

• 🔌 Connect the cable to the phone turned off.
• 🔊 Press the Volume Up button before the logo appears.
• 🔄 Select the "Reboot to System" buttons.
• 📱 If the screen catches fire but the phone doesn’t load, try “Wipe Data” (the data will be deleted).

It's important to understand that logging into Recovery or Fastboot is a low-level mode that works regardless of the state of the main operating system, and if the phone responds to these commands, then the motherboard and display are intact, and the problem is localized to the button mechanism or software boot failure.

Application ADB-start-up

The most powerful software tool for managing Android devices is Android Debug Bridge (ADB). If your phone has previously been debugged USB (USB Debugging, you can run your phone with your computer. This method requires a PC, a Xiaomi driver installed. USB Driver and platforms SDK Platform-Tools.

First, connect the phone to your computer. In some cases, a PC connection can wake the device up by itself if debugging is enabled. Open the command line on your computer in the ADB folder and type in a command to check the connection. If the phone calls back, you can send a command to reboot.

adb reboot

This command forces the device to restart, and if the phone is in deep sleep or off but is powered, adb reboot often forces it to turn on. If the standard reboot doesn't work, try the command to enter recovery mode, where it's easier to start the system:

adb reboot recovery

⚠️ Attention: Method C ADB It only works if the debugging mode has been activated before. USB. On a completely new or reset phone without debugging enabled, this method won’t work.

If none of the commands is executed, check the list of connected devices with the adb device command. If the device is displayed as unauthorized, you will need confirmation on the phone screen, which is impossible when the screen is off, in which case this method, alas, is not available.

Use of assistant applications and automation

If you miraculously turned your phone on (like it turned on when charging or using previous methods), your first priority is to install a software solution that replaces the physical button. There are many applications on Google Play, such as Assistive Touch, Button Mapper or Volume Power.

The principle behind it is to reassign functions. You can set the phone to turn on or wake up when you double tap on the screen, when you plug in a charger, or when you press the volume button for a long time. For Xiaomi phones with their rich themes and settings, this is the most viable long-term solution.

You should also look at the built-in Quick Commands or automation scenarios if your version of MIUI allows you to create macros, such as creating a script that says, "If it's 08:00, turn on the screen," which will help you use your phone at least during certain hours without a physical button.

Don’t forget that third-party button replacement apps require special permissions, often through ADB. Once you install the app, you’ll likely have to execute a command:

adb shell pm grant com.package.name android.permission.WRITE_SECURE_SETTINGS

This will allow the application to control system functions, including turning on the screen, without this permission, the application will only work partially, for example, only emulate the presses, but not wake the phone.

Comparison of Startup Methods Without Power Button

To structure the information and choose the most appropriate way for your situation, let's compare the methods we've reviewed on the key parameters of complexity, requirements and efficiency. Not all methods are universal, and success depends on a particular Redmi or POCO model.

As you can see from the table, ADB gives you the most control, but requires a lot of preparation. Recovery is the most reliable emergency option if the phone is completely off. Apps are the best solution for comfortable operation after successful switching on.

💡

A combination of methods (e.g., activation via Recovery and subsequent installation of an assistant app) gives a 100% guarantee of a device being brought back to life.

Radical measures: disassembly and closure of contacts

If the software is exhausted and the phone is vital, there is a physical intervention option, which requires precision, a thin screwdriver, a plastic blade and tweezers. Attention: opening the case may take you out of warranty, so only use it if the warranty has expired or the phone is not repairable in the service.

The idea is to directly close the contacts of the power button on the motherboard, so you need to carefully remove the back cover (or screen if the unibody design), find the plume going to the power button, and close the corresponding contacts on the board with tweezers, which simulates the press of a button.

On some Xiaomi models, the power button is a separate module connected by a plume, so you can simply unplug the button plume and gently close the contacts on the motherboard connector, which is less risky than soldering or picking at the button itself.

• 🔧 Turn off the phone (if it is not already off) and remove it. SIM-map.
• 🌡️ Heat the edges of the body with a hair dryer to soften the glue.
• 🔓 Carefully slap the cover with the mediator.
• ⚡ Find the button contacts and close them with a metal object.

Once the phone is on, install the button management app right away or set up an automatic on-charger to avoid repeating the disassembly procedure every time, a temporary solution that will save data or wait for repairs.

⚠️ Warning: When disassembling a smartphone, there is a high risk of damaging the plumes of the display or battery. If you are not confident in your abilities, you better trust this to the professionals.

Prevention and Configuring of Alternative Management

Once the phone is successfully turned on, it is important to set the system so that the breakage of the button does not become critical in the future.In the MIUI settings, there is a function “Unlock the Screen” that can be configured to double-touch. Go to Settings → Lock Screen → Double-touch to enable.

You can also activate the “Raise to Turn” feature (if supported by your model’s sensors), which will wake the screen with a simple hand movement, eliminating the need for a physical button, and you can use widgets or the Google Assistant voice assistant to turn off the phone.

To turn off voice, say, "OK, Google, turn off your phone." The system will request confirmation, but this will do without buttons. In addition, set up automatic on and off on a schedule in the Settings → Battery → Scheduled tasks. The phone will turn on in the morning and off at night.

Check the battery status regularly. If the phone accidentally shuts down due to a discharge, you will have to resort to "dancing with a diamond" to turn it on again. Keep the charge above 20% and avoid situations where the device may completely land at the wrong time.
