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

When the smartphone is completely discharged and the power button is no longer responsive, it can take any Xiaomi owner by surprise. This is not just an inconvenience, but a real problem blocking access to important contacts and data. Fortunately, the Android operating system and the hardware of modern gadgets have workarounds for such cases.

Before you take your device to the service center, you should try a number of software and hardware techniques that often help you start the system without using a physical key. In this article, we will examine all the existing ways of activating the device, from simple connections to charging to complex manipulations with debugging over USB. The effectiveness of each method depends on the specific model and battery condition.

Some of the actions described below require prior preparation or the presence of certain tools, such as a computer or a charger with support for fast charging. It is important to act consistently so as not to aggravate the situation and not damage the software part of the gadget.

Use of charger and computer

The easiest and safest way to try to revive the device is to connect to a power source. Many Xiaomi models automatically turn on when connected to a charger, especially if the battery has been completely discharged. This method works at the level of a hardware controller that responds to the voltage.

And to do this, you're going to need an original cable and a power supply. You plug your phone into an outlet and wait a few minutes. If the screen lights up and the Mi logo comes up, you're in luck. If the device only shows the charging light, try plugging it into a charging light. USB-port.

Connecting to a PC can trigger debugging mode or simply wake up the system, as the computer sends certain signals over the data bus. Sometimes it helps to quickly reconnect the cable to the smartphone connector when it is already connected to the power source, which creates voltage surges that the system can perceive as a signal to start.

💡

Use a cable that supports data transfer, not just charging, so that the computer can send wake-up signals to the device.

Volume button combination method

If standard turn on is not possible, a combination of audio buttons comes to the rescue. On many Xiaomi devices, pressing the volume or decrease button along with connecting the cable allows you to enter special boot modes, this can be Fastboot or Recovery Mode.

The algorithm of actions usually goes like this: press the volume button (usually "minus") and without releasing it, connect a cable connected to the computer. The screen should show an image with a hare in a hat-eared or recovery menu.

In the Recovery menu, you can navigate with volume buttons and you can choose with a power button. If the power button doesn't work at all, sometimes you can wait for a long time: some phones automatically reboot after a timeout or menu item selection, and you can also press both volume buttons at the same time when you plug in the cable.

Including via ADB and computer

For advanced users who have previously had USB debugging enabled, there is a powerful tool called ADB (Android Debug Bridge), which allows you to send commands directly to the operating system even if the screen does not respond to touch, but if the phone is completely turned off, this method will only work in conjunction with the Fastboot login method.

First, you need to install Xiaomi drivers and the SDK Platform Tools platform on your computer. After connecting the phone in Fastboot mode (via volume and cable), open the command prompt in the folder with ADB. Enter the command to reboot the device in normal mode.

adb reboot

If the device is in Fastboot mode, the command will look different and requires the fastboot utility:

fastboot reboot

This is the most reliable method, because it programmatically forces the controller to reboot. It is important that the drivers are installed correctly, otherwise the computer will not see the connected gadget. In Windows Device Manager, the phone must appear as Android Bootloader Interface.

Use of accessories and peripherals

And don't forget to look at external accessories that can help solve the problem. USB-hub OTG-Connecting a mouse or keyboard sometimes sends a wake-up signal to the device.

If you have a wireless mouse with USB-Receiver, try to connect it through OTG. Pressing a button on the mouse can be perceived by the system as an external interrupt that will wake the screen. There are also special applications and scripts that can be activated when you connect the charging, but they require pre-configuration.

Another option is to use a docking station. Some of Xiaomi's original docks have their own buttons or mechanisms that can trigger turn-on when you install a smartphone. This is a less common but possible scenario for owners of the smart home ecosystem.

Comparison of Incorporation Methods without a button

To make it easier for you to choose the right option, we have organized the basic methods into a table that will help you assess the complexity and the conditions for each method.

As you can see from the table, the methods range from simple household activities to complex technical manipulations, and the choice depends on how deep you are willing to dive into the solution and what tools are at hand.

Interim solution: “Schedule Inclusion” function

If you managed to turn your phone on with one of the above methods, but the button never worked, it is critical to prevent it from turning off again. For this, the MIUI and HyperOS shell have a useful feature called “On and off on schedule”.

Go to Settings → Battery → Schedule on and off. Set the turn on time a few minutes ahead of the current time. Now, even if the phone runs out and turns off, it automatically turns on itself when you connect to a charge or at a predetermined time, without the use of a button.

⚠️ Note: This function only works if the phone has not been completely de-energized (the battery has not been removed if it is removable, or the backup capacitor has not discharged to zero.

You also need to ban the shutdown or use applications that block the power button software, which will allow you to use the smartphone until the repair without fear that it will go out and will not turn on again.

💡

Set up auto-on schedule is the only way to protect yourself from a situation of complete locking of the device in the future.

Hardware closing contacts (for experienced)

The most radical method that requires disassembling the case is to directly close the contacts of the switch button on the board, a method that is only suitable for those who have experience with small electronics and understand the risks of short circuit.

You need to gently open the back cover, find the plume or contacts that go to the power button, and then you lock them with tweezers (simulating a push) and you can also plug in the power, and you can start the device. Some boards have special test points for turning on, which are designated as PWR_ON.

⚠️ Warning: Sloppy closure of contacts can cause the motherboard to burn, use only isolated tools and act at your own risk.

After successful inclusion in this way, it is strongly recommended to immediately configure “Schedule Enablement” or replace the button plume, since the device cannot be operated for a long time in the disassembled state.
