The power button on Xiaomi Redmi does not work: complete solutions

When the power button on your Xiaomi Redmi stops responding, it causes panic, especially if the screen is locked or the device is getting stuck.This is a common hardware problem that smartphone owners face after a certain lifetime or fall. Often users mistakenly believe that the phone is completely out of order, but in most cases the system continues to work and access to data can be restored.

There are several effective ways to get around a broken button using software or external hardware manipulations. It is important to understand that the methods of solving depend on the current state of the device: whether the screen is on, whether the touchscreen or smartphone is fully black. In this article, we will discuss in detail all options, from simple software settings to complex engineering solutions.

⚠️ Warning: If your smartphone is warranty-free, self-opening the case to repair the button may result in a loss of warranty obligations.Be careful when physically impacting the device.

Diagnostics of the problem and primary actions

Before we go to radical measures, we need to determine exactly the nature of the malfunction, most often the problem lies in the mechanical wear of the microswitch under the button or in the sticking of contacts due to moisture, sometimes it is a software failure, when MIUI stops correctly processing signals from the hardware buttons.

Try to gently press the on button with different forces, but without fanaticism, to avoid sticking.If you feel that the button's stroke has become too soft or, conversely, the button "failed" and does not emit a characteristic click, it is a physical injury.

In cases where the phone reacts to the charger's connection with vibration or sound, but the screen does not light up, the problem may be in the plume or display, not just in the button.

• 🔍 Check the smartphone’s response to the connection to the charger.
• 🔍 Evaluate the tactile sensations of pressing: is there a click or a move of the button?
• 🔍 Try pressing the Down Volume button along with the power button (if it works even a little) to enter Recovery mode.
• 🔍 Connect the phone to your computer and check if it is defined as a device in Task Manager.

Software reboot without power button

If your Xiaomi Redmi is on, but the screen is gone (sleep mode), and it is not possible to wake it up in the usual way, you can use the system functions to force the reboot. This is true for models that support the function of “Double touch to wake up” or “lift to wake up”.

Activate these features in advance if the button is still showing signs of life. Go to the settings, select the Lock Screen section and find the appropriate items. Double tap on the screen often helps the device when the physical button ignores the presses.

For models with a security app installed or advanced MIUI settings, you can set your on and off schedule. If you set your turn on time, the phone will start at a given hour, allowing you to access the system and save data.

💡

Install the Double-Tap to Turn on Screen function right now while the button is still running, this will be your salvation in the future.

Some firmware versions work with a combination: pressing the volume button "Up" or "Down" for a long time can initiate a reboot or call assistant through which you can try to launch the application. However, this does not work on all Redmi models and depends on the version of Android.

Using ADB to control your smartphone

The most powerful software method to solve a problem when the power button on Xiaomi does not work is to use the Android debugging bridge (ADB). This method requires connecting the phone to the computer through USB-cable and availability of installed drivers.

To start, you need to activate the USB debugging mode. If the phone screen responds to touch, but the power button doesn't work, unlock the device with a pattern lock, fingerprint or Face ID. Then go to Settings → About Phone → MIUI version and quickly press 7 times to activate the developer menu.

After activation, go to Advanced Settings → For developers and turn on Debugging over USB. Connect your smartphone to your PC, download the Platform Tools package and open the command line in the tool folder.

adb reboot

This command will force the device to restart. If the phone is turned off and not turned on, but is determined by the computer, you can try the command to turn on, but it does not work on all models due to the security limitations of the bootloader.

Special assistant applications

Android smartphone owners can use third-party apps that add a virtual on-screen button, a temporary solution that allows them to use the phone before repairs. Popular apps like “Assistive Touch” or “Button Mapper” create a floating button on the display.

Install this app from the Google Play Store while the device is still functioning, and once set up, you can lock the screen, reboot the phone, and do other things just by touching the virtual button, which is especially useful if the physical button has completely stopped working.

Some apps allow you to adjust the actions when you connect a charger. For example, when you connect a cable, the phone can automatically turn on or go into unlock mode, which bypasses the need to use the power button.

• 📱 Assistive Touch – Creates a floating menu with a lock button and other features.
• 📱 Button Mapper – allows you to reassign the functions of the volume buttons to turn on the screen.
• 📱 Volume Power – a specialized application for turning on the phone with volume buttons (requires root rights).

⚠️ Note: Applications requiring root rights for deep integration into the system may disrupt the warranty software and lead to denial of service.

Hardware methods and entrance to Recovery

If software methods don't work, you'll have to resort to hardware solutions. Entering Recovery or Fastboot mode is often possible even with a power button not working, if you use certain combinations or close contacts.

To enter Fastboot on many Xiaomi models, it is enough to press the volume button and connect it. USB-The phone needs to turn on in a special mode, where you see a hare fixing an android, and from there you can choose the reboot option, which will start the phone normally.

There's also a double-clamp method. Press both volume buttons ("Up" and "Down") at the same time and plug in the charger. On some older Redmi models, this triggers a boot mode selection menu. If the "Up" or "Down" button works, you can navigate to Reboot.

Table of keyboard combinations for different models

Different Xiaomi and Redmi models may have their own features in the work of the bootloader. Below is a table that will help you navigate in combinations to enter service modes without using the power button in the standard scenario.

Radical measures: closing contacts

If nothing works and the phone needs to be turned on, there is a method that requires the back cover to be opened, which is only suitable for advanced users and can permanently disable the device if you are careless, and the essence of the method is to short-term circuit the contacts of the switch button on the board with tweezers.

To do this, remove the back cover (preheated with a hair dryer or on the heating panel), unscrew the protective screens and find the plume of the power button. Carefully closing the switching contacts on the motherboard with a metal object (tweezer) for a fraction of a second, you can initiate the start of the system.

Once you're successful, back up your data immediately, which is not a repair, but an emergency measure to save information, and you'll still have to replace the button to make a full use of your phone.

💡

Closed contacts is an extreme measure to save data, not a way to constantly operate a smartphone.
