Xiaomi phone does not turn off and does not respond to the power button: 7 working ways to solve the problem

The situation is familiar to many: Xiaomi smartphone suddenly stopped responding to the press of the power button. The screen can be black, stuck on the logo or show a working interface, but neither forced reboot nor holding the button helps. What is the reason and how to regain control of the device without going to the service center?

The problem is more common on Redmi Note 10/11, POCO X3/X4 and Mi 11, but it also affects new devices. Software failures (system freeze after update, application conflict) and hardware malfunctions such as button wear, plume damage or power connector damage, and in this article we will examine all possible scenarios, from simple to radical, with data preservation and device security in mind.

Important: If the Xiaomi phone not only doesn’t turn off, but also overheats or makes uncharacteristic sounds (such as squeaking when you connect a charger), immediately disconnect it from the network and don’t try to turn it on until you diagnose it.

1. Forced reboot: button combinations for Xiaomi

The first and most secure method is hardware reset, which doesn't delete data, but reboots the system, interrupting the hanging processes. Most Xiaomi models have a universal combination:

For devices with power and volume button:

1. Press the Power button + Volume increase for 10-15 seconds.
2. Let go when the Mi logo or vibration appears.

For devices with a Bixby button (e.g. Mi Mix 2S):

If the combination does not work, try an alternative:

• 🔋 Connect the charger and hold the power button 30+ Sometimes it works when the battery is empty.

Battery discharge: a radical but effective method

If the Xiaomi phone doesn’t respond to any combination of buttons, you can try to completely drain the battery.This method works because at zero charge the device automatically shuts down, and after connecting the charge can boot in normal mode.

How to properly discharge:

⚠️

Note: Do not use this method often – deep discharge reduces the life of lithium-ion batteries, and it is not suitable for devices with a faulty battery (blown or damaged).

If the phone doesn't turn on after it's discharged, the problem may be in the power controller or the battery itself, which will require a diagnosis at a service center.

💡

Before discharging, check if the phone is connected to wireless charging or power bank – this can interfere with the process.

3. PC Connection: Diagnostics via ADB or Mi Flash

If the Xiaomi phone doesn’t turn off but is determined by the computer, you can try rebooting it via ADB (Android Debug Bridge) or flashing it back again using the Mi Flash Tool.This method requires pre-tuning, but often saves in critical situations.

Method 1: Reboot through ADB

1. Connect your phone to your PC through USB-cable (preferably original).
2. Open the Command Prompt (Windows) or Terminal (macOS/Linux).
3. Enter the command: adb devices If the device is defined, execute: adb reboot

Method 2: Firmware via Mi Flash (for power users)

• 🖥️ Download the official firmware for your model.
• 🔧 Install Qualcomm or Mediatek drivers (depending on the processor).
• 📱 Put your phone in Fastboot mode (if possible) or EDL (This may require a disassembly).
• 🔄 Start the Mi Flash Tool and follow the instructions.

⚠️

Note: The firmware via Mi Flash deletes all data on the device. If the phone is not detected in Fastboot, but responds to charging (the indicator is on), try the discharge method first.

Checking the power button: mechanical failures

If a Xiaomi phone doesn’t respond solely to the power button, but it charges normally and turns on via the cable, the problem may be with the button itself. This is typical for devices older than 2-3 years, where contacts oxidize or wear out.

How to diagnose:

• 🔍 Light a flashlight on a button – if it is drowned or stuck, it probably got dirt or moisture under it.
• 🎵 Press the button and listen: creaking or crunch indicates mechanical damage.
• 🔌 Try turning your phone on via charging connection – some Xiaomi models start when connected to the network.

Provisional decision:

1. Carefully tap on the power button area (like a pen), sometimes helping to "close" the contacts.
2. Use an alcohol wipe to clean the button (without disassembling the phone!).
3. If the button is completely inoperable, turn the device on via ADB or wait for the battery to drain.

For permanent repairs, you will need to change a button or a plume. The cost of service in service centers is from 800 to 2000 rubles (depending on the model).

5. Alternative ways to turn off through software

If the Xiaomi phone screen is working but the power button is not responding, you can turn the device off through software methods. This is true for devices with an unlocked bootloader or root rights, but some methods work on standard firmware.

Method 1: Recovery Menu (Recovery)

1. Press Volume Up + Power before the Recovery menu appears.
2. Select Reboot → Power Off (use volume buttons for navigation).

Method 2: Using the "Screen buttons" application

• 📱 Install Screen Off and Lock (if your phone still responds to touch).
• 🔘 Set up the shutdown widget on the main screen.
• 🔄 Use the Google Assistant with the command “Switch off the screen".

Method 3: Through ADB (if debugging is enabled)

adb shell input keyevent 26

This command simulates the pressing of the power button.

⚠️

Note: If the Xiaomi phone doesn’t respond to touch, but the screen is working, don’t try to repeatedly press the display – this can damage the touchscreen plume.

6.When to contact the service: signs of serious malfunctions

Not all power button problems can be solved on their own.If none of these methods worked and the Xiaomi phone still doesn’t turn off, it could indicate hardware breakdowns requiring professional intervention.

Signs that you need a service:

• 🔥 The phone is overheated even when it is off.
• 💥 The battery swelled (seems to deform the body).
• 🔌 The device is not defined by any computer (even in Fastboot).
• 🛠️ Power button physically damaged (cracks, chips).
• 🔄 The phone is turned on / off without pressing buttons.

What to do before visiting the service:

1. Take a picture of the IMEI device (on the box or under the battery if you have access).
2. Delete. SIM-Card and memory card (if the phone sometimes reacts).
3. Do not try to disassemble the device yourself - this will deprive you of the warranty (if it is still valid).

On Xiaomi models with a Mediatek processor (for example, Redmi) 9A, POCO M3) with incorrect firmware through SP Flash Tool can burn out NAND-Memory that will result in complete data loss without the possibility of recovery.

7.Prevention: How to Avoid Power Button Problems

To make the power button on Xiaomi last longer, follow the simple rules:

• 🚿 Avoid moisture – even a little humidity can cause contact oxidation.
• 🧴 Clean the button from dust and dirt regularly with a dry soft brush.
• 🔋 Do not press the power button with excessive force - this deforms the mechanism.
• 🔄 Use a software shutdown (via menu or voice assistant) to reduce the load on the button.

It is also recommended to disable automatic reboot in the developer settings (Settings → About Phone → MIUI version – press 7 times, then return to Additional Settings → For Developers → Automatic Reboot).

💡

If the power button starts to stick, immediately clean it with alcohol and reduce the frequency of use, the longer you ignore the problem, the greater the risk of a complete failure of the mechanism.
