How to turn on Xiaomi Redmi if the power button doesn’t work

When your favorite Xiaomi or Redmi smartphone suddenly stops responding to the power button, it can take anyone by surprise. Often at the most inopportune moment when the battery is already dead and you urgently need to make a call or check important information. The mechanical power button is one of the most vulnerable design elements, subject to constant physical stress and wear of the contacts.

Fortunately, the architecture of the Android operating system and the specific features of the MIUI shell or HyperOS provide several workarounds to start the device without using a regular mechanical switch. In this article, we will discuss in detail all possible methods, from simple charging manipulations to using advanced computer utilities to diagnose and start the system.

Before you panic and carry the gadget to the service center, it is worth trying software methods of resuscitation. USB-The cable allows you to start the phone 90 percent of the time, even if the Power button is completely physically destroyed. It's important to act consistently and closely monitor the response of the screen and the LED light to choose the right algorithm for actions.

Diagnostics: Why the button stopped working

Before you start emergency switching on, you need to understand the nature of the malfunction. Most often the problem lies in mechanical wear of the plume or oxidation of contacts inside the housing, especially if the device has previously come into contact with moisture. In rare cases, the failure can be software when the system freezes in a deep sleep state and does not respond to interruptions.

If your Redmi has a removable battery (which is true for older models), the first thing to do is to remove and insert the battery back. For modern monolithic designs, it is important to check the integrity of the charging connector. Sometimes contamination of the Micro-USB or Type-C port interferes with the correct connection determination, which blocks automatic start.

⚠️ Warning: If the charger starts to heat up in the upper part of the case or makes strange clicking sounds, immediately disconnect it from the network.This may indicate a short circuit in the button circuit or power controller.

Also worth paying attention to the behavior of the LED indicator, if when you connect the charge it lights up, but the screen remains black, this is a good sign that the motherboard is alive, and the task is only to give a wake-up signal. In cases where the indicator is silent, it may require a deeper discharge or, conversely, a long charge before trying to turn on.

Charging method: automatic start and system response

The easiest and safest way to try Xiaomi without a button is to use a standard charger. Many of the brand’s smartphones are programmed to automatically turn on when connected to a power source if the battery is completely exhausted.

If the device is in a deep discharge, the screen may not immediately light up. Leave the phone charging for 15 to 30 minutes. In some cases, the system may activate itself when the charge level reaches a certain threshold necessary to safely start the operating system, especially for models with Qualcomm power controllers.

There is also a hot connection method. If the phone is off but the battery is not deep zero, try this sequence: press the Volume Down button and hold it and connect the charging cable to the computer (not the socket), which often puts the device in Fastboot mode, where you can try to boot the system.

💡

Use the original cable and power supply. Cheap analogues may not provide enough current to initiate the start-up process, especially if the battery is old.

Importantly, the charging response may depend on the version of MIUI. On newer versions of the shell, the automatic start when connected to a PC can be blocked for safety reasons, whereas the connection to the 220V outlet will work reliably. Try combining the cable connection with the compression of both Volume Up + Volume Down buttons at the time of connection to charging.

Using Recovery Mode to Reboot the System

Recovery Mode is a powerful tool built into every Xiaomi smartphone that allows you to control the device at a low level, you can get into it without the power button, using only the volume keys, and this method is effective if the system is not hanging dead, but just gone to sleep.

To enter recovery mode, do the following: turn off the phone completely from charging (if it was connected). Press the Volume Up button and, holding it, connect a USB cable connected to your computer or charger. Keep the button pinched until the Mi logo or Recovery menu appears.

Once the menu is available, you can navigate with volume buttons (up/down) and power buttons to select a point. Because the power button doesn't work, we use a trick. In some versions of Recovery, you can select "Reboot to system," and if you release the buttons carefully, the phone can start. However, a more reliable way is to select this point when the screen goes out for reboot, quickly press the button combination to log in to Fastboot, and from there, try to initiate a normal boot.

⚠️ Warning: Do not select "Wipe Data" from the Recovery menu unless you have a backup. This action will result in the total loss of all photos, contacts and applications.

An alternative option for advanced users is to use the "Connect with MIAssistant" option. If you choose one (volume button navigation, confirmation sometimes works by swipe or timeout), you can try connecting to your phone via the Mi Flash Tool program on your PC. In some cases, the mere fact of connecting to a PC in this mode can "wake up" the device and allow it to boot if the appropriate permissions were in the debugging settings.

Starting through a computer and ADB-team

If the phone has previously been debugged USB (USB Debugging, then the most effective way to enable will be using the Android Debug Bridge debugging bridge (ADB). This method allows you to send commands directly to the operating system, bypassing physical buttons. To work, you will need Xiaomi drivers and the installed Platform-tools package on your computer.

Connect the phone that is turned off (or hanging) to your computer. If the device responds to the connection with sound or vibration, open the command line on the PC in the folder with ADB. Enter the command to check the connection: adb devices. If the device appears in the list, then there is a connection, and you can try to control the power programmatically.

To try to turn on or reboot, use the following command in the terminal:

adb reboot

This command sends a signal to restart the device, if the phone was just in sleep mode, it will start. If you want to turn it off, the command may not work without pre-setting authorization, in which case you can try the command to enter bootloader mode:

adb reboot bootloader

Once this command is executed, the phone will go to Fastboot mode. In this mode, you can use the Mi Flash Tool utility or just the fastboot continue command (or fastboot reboot) to try to start a normal Android boot. Often, the transition through the modes “wakes up” the power controller, and the phone starts working normally.

Table of launch modes Xiaomi Redmi

Understanding the different modes of operation of the smartphone helps you choose the right power-on strategy. Below is a comparative table of the main modes available on Xiaomi and Redmi devices and how to log in without a power button.

The most useful thing for us is Fastboot mode, which is that when you get into Volume Down when you connect the cable, you get control of the device. It's often easier to get out of Fastboot mode through software commands than it is to try and guess when to turn on through Recovery.

EDL (Qualcomm Emergency Download) is a last resort, and if the phone doesn’t turn on in any way, entering this mode (often requiring disassembly and closure of contacts on the board) allows you to flash the device clean, but this requires an account with authorization from Xiaomi, which makes the method difficult for the average user.

Software solution: auto-start on schedule

If you have managed to turn your phone on temporarily (for example, the button still sometimes works or you used the methods above), it is critical to configure the automatic turn on function, which will allow you to use the smartphone in the future without having to look for ways to activate it every time.

MIUI and HyperOS have a built-in “Schedule Turn on and off” feature in the shell. Find this item in the settings by going to Settings → Battery → Scheduled On and Off (the path may vary slightly in different versions). Activate the option and set the time, for example, 5 minutes ahead of the current one.

💡

Setting up autostart on schedule is the only way to (long-term) use a phone with a completely broken power button.

Once the phone is turned off by the timer (or you turn it off programmatically), it will automatically turn on at a given time, and you can also set up daily turn on, which is temporary, but allows you to keep access to data and connections until you replace the button plume.

You can also use Google Play assistant apps that emulate on-screen button pressing, but they require root rights or special ADB permissions that are only given on the device on, so the regular schedule function remains the most reliable software crutch.

Mechanical Methods and Temporary Fixes

When software is exhausted, you have to do physical things, and if the button fails or it crashes, sometimes it helps to tap the body carefully around the power button, and it can temporarily restore contact within the machine, and you can do this without fanaticism, so you don't damage the screen or the motherboard.

In some cases, it helps to press the switch area with a finger or blunt object with a wide contact area, if the contacts are oxidized under the button, the pressure can penetrate the oxide layer, and you can also try to slightly curve the case in the button area (a risky method, suitable only for experienced ones) to close the contacts of the plume.

If you are ready for more decisive action and the phone is not warranty, you can remove the back cover (if it is removable or easily opens) and directly close the contacts of the switch button on the board with tweezers. This is guaranteed to turn on the device, but requires caution not to short other elements.

⚠️ Warning: Disassembling your smartphone or trying to close contacts with tweezers automatically voids the warranty. If you are not confident in your abilities, you should trust this procedure to the professionals in the service center.

As a temporary solution for non-removable battery models, you can leave your phone permanently connected to a Power Bank or charger. Many Xiaomis, when connecting charging, behave like an active device, allowing you to receive calls and notifications even with the screen turned off (but charging) if the settings were ticked “On screen when charging”.
