The situation where the physical power button on a smartphone stops responding is one of the most stressful for the owner.The Xiaomi Redmi Note 4, despite its reliability, is not immune to mechanical breakdowns, and a failure of the Power key can turn the device into a brick that cannot be turned off or rebooted in the standard way. Owners often panic, believing that without a hardware button the phone is doomed to eternal work to full discharge or requires urgent repair in the service.
But the Android operating system that runs the MIUI has several software-based power management methods. Even if physical contact is disrupted, program interrupts and system commands remain available to the user. There are many ways around this problem, from using special applications to connecting to a computer via a debugging bridge.
In this article, we will take a look at all the working methods of rebooting and turning off the Redmi Note 4 without the help of the power button. You will learn how to use accessibility features, system codes and computer utilities. The main condition for the success of most software methods is that the smartphone screen must be active and responsive to touch. If the display also does not work, the situation becomes complicated, but there are still solutions.
Use the off menu through the notification panel
The simplest and most obvious way, often forgotten in panic, is through the standard system interface: If your smartphone is on and the screen responds to touch, you can initiate the process of turning off or rebooting through the software menu, which requires unlocking the device and lowering the notification curtain from top to bottom.
At the top of the Quick Settings panel, wireless module control icons are usually located, often with a lightning button or power icon, and clicking on this element triggers a system dialog box with options. Depending on the version of MIUI, this window may contain "Stop", "Reset" or "Flight Mode" buttons.
If the standard button is not available, try pressing the volume button or using the voice assistant if it is configured. However, Redmi Note 4 most often uses the classic method through the control center. It is also worth checking the settings of the home button or navigation buttons if they are reprogrammable, although this model is rare.
It’s worth noting that this method only works when the screen is active, and if the phone is locked and the screen is gone, you’ll have to wake the device up first in other ways, such as taking a call or getting a notification that will light up the display.
Quick buttons and special features
Android has powerful tools for people with disabilities that can be a rescue when hardware buttons break. A feature known as the Special Features Menu or Assistive Touch (in various implementations) allows you to display a virtual floating button that duplicates the basic functions of navigation and power management.
To activate this feature on the Xiaomi Redmi Note 4, you need to go to the settings section. The path usually looks like: Settings → Advanced Settings → Special Features → Special Features menu. Once the switch is turned on, a translucent button will appear on the screen that you can move, and when you click on it, you will open a menu where there are options for Lock, Turn off and Reset.
This is especially useful because the virtual button is always on hand, and you can set it up automatically when you turn on your phone, so you can not only reboot the device, but also take screenshots, adjust volume and lock the screen without using physical keys.
⚠️ Warning: Do not install third-party button emulation apps from questionable sources before the button breaks.It is better to set up the system function in advance, as long as you have full control of the device.
If the standard feature menu seems uncomfortable, there are analogs like “Assistive Touch” or “Virtual Button” in the Google Play or GetApps store, which offer more flexible configuration of the appearance and location of virtual keys, including creating your own macros to reboot.
Reboot via computer with ADB
For more advanced users who have broken the power button on Redmi Note 4, the ideal solution is to use the Android Debug Bridge debugging bridge (ADB). This tool allows you to send system commands directly from your computer to your smartphone via USB-This method requires prior preparation, but it is one of the most reliable.
The first and most important condition is that the phone must be enabled debugging via USB. If you did not have time to activate this function before the button breaks, the method will not work. To enable, go to Settings → About phone and 7 times click on the build number to unlock the menu for developers, and then turn on the item “Debug by USB”.
Once you connect your smartphone to a PC with Xiaomi drivers installed and ADB platform tools, you open the command line. In Windows, this is done through the Win + R combination and input the cmd command. In the window that opens, you enter a command to check the connection: adb devices. If a message appears on the phone's debugging resolution screen, you need to confirm it by touching.
The following command is used to perform the reboot:
adb rebootIf you want to turn off the device, the command will look like this:
adb shell reboot -pThis method is good because it works even if the touch screen is partially not functioning, as long as it works. USB-It also allows you to enter Fastboot or Recovery mode with the adb reboot bootloader or adb reboot recovery command, respectively, which you may need to flash back.
⚠️ Attention: Adb shell reboot command -p On some versions of Android, you may not turn off completely, but just go to standby mode.
Automatic reboot on schedule
The MIUI shell on the Redmi Note 4 has a built-in and very useful automatic reboot feature on a schedule, not just a way to reboot your phone right now, but also a great preventive measure to keep the system running smoothly without user input.
To set up automatic reboot, go to Settings → Battery and Performance (or simply “Battery”). In the upper right corner of the screen is the gear icon or three menu dots. In the list that opens, select “Task Planner” or “Out and Off.”
Here you can set the time when the phone should turn off and on, for example, you can set the switch off at 03:00 a.m. and turn on at 03:05 a.m. This will allow the device to “rest” and clear RAM daily, which is especially important for problems with physical buttons.
The advantage of this method is that it's autonomous, you don't have to look for a computer or think about virtual buttons, but there's a caveat: if the phone is already off and the power button doesn't work, the "Switch on" function may not work, because it often requires a power interruption or a hardware trigger to start the process, which depends on the functionality of the button controller.
However, as a way to reboot the device regularly, it is the best option, preventing the accumulation of system debris and the freezing of processes that might require an emergency restart.
💡
If the auto-on function doesn’t work after shutting down on a schedule, try connecting your phone to a charger. On some Xiaomi models, the power connection simulates pressing the power button.
Use of third-party applications
If system tools seem limited, the app store offers a variety of utilities designed specifically for power management. Apps like Power Button to Volume Button or Assistive Touch can reassign volume button functions or create floating widgets on the screen.
The way these programs work is to intercept system events, for example, an application can set up a double-pressing of the volume button to call the shutdown menu, which is extremely convenient when the main Power button is dead. You just need to press the side key to access the reboot options.
The other class of applications is desktop widgets, and once you install one, you can put a big red turn off button right on the main screen, and one tap, and the phone starts the shutdown process, which is faster than going through the settings every time.
Some features may not work without root rights, but basic features are available to regular users. Before installing, read reviews carefully to make sure you are compatible with your version of Android.
☑️ Checking readiness for software reboot
Engineering menu and codes for diagnostics
At the back of Xiaomi's system, there's an engineering menu that can be accessed through a set of special code in the Phone app, and while there may not be a direct shutdown command, it's a menu that allows you to diagnose and sometimes manage power settings.
The code ##64663## is usually used to enter the engineering menu on Redmi Note 4. Once inside, you will see a list of tests. We are interested not so much in testing as in checking whether the system responds to software requests. Some firmware modifications in the CIT (Calibration and Information Test) menu have options for rebooting modules.
There's also a code called ##7780## that causes factory resets to delete user data. Use this command with extreme caution! It doesn't just reboot the phone, it erases all data. It's a last resort if the phone freezes and other methods don't help and the data doesn't matter to you.
The more secure code is ##4636##. It opens the phone information menu. Although there is no direct reboot button, this section confirms that the system responds to input, and you can, for example, switch the network type through it, which sometimes helps to revive the suspended modem without fully restarting.
Secret codes for Redmi Note 4
What to do if the phone is completely off
The most difficult situation is when the Redmi Note 4 is already off and the power button is not working, in which case the software methods from the screen will not help, since the system is not running, and here comes the hardware features of the smartphone design.
The first method is to connect to a computer. Some versions of Xiaomi bootloader respond to the connection to the computer. USB-Connect the phone with a cable to the computer and simultaneously press both Volume Up and Volume Down buttons. 10-15 This can force Fastboot mode to start, where you can already select the Start option to boot the system using volume buttons to navigate.
The second method is to connect to the charger. Leave the phone on charge for a few hours. Sometimes, when the battery is fully charged, the system itself initiates an on or vibration signaling readiness. Once a logo or vibration appears, you can try to apply methods from the beginning of the article.
A third, more risky method is to simulate a push, and if the button falls inwards but the contact is there, you can gently (without undue effort) press the button area with a toothpick or a thin plastic tool, and if the button is physically removed from the plume, you will need to disassemble the case to close the contacts on the board.
| Method | Conditions required | Difficulty | Efficiency |
|---|---|---|---|
| Shutdown menu | Work screen, phone on | Low. | Tall. |
| ADB team | PC, cable, enabled debugging | Medium | Tall. |
| Auto-reboot | Schedule set up | Low. | Medium (planned) |
| Connection to PC | Phone off, Fastboot mode | Medium | Depends on the software version. |
⚠️ Attention: Attempts to disassemble the phone to close the contacts of the buttons on their own can lead to loss of warranty and damage to other components.
