How to reboot Xiaomi if the power button doesn’t work: all the working ways

Why Xiaomi’s power button is failing and what to do

The power button on Xiaomi smartphones (including the Redmi, POCO and Mi series) is one of the most vulnerable elements. According to service centers, up to 15% of calls are due to mechanical failures of this key. The reasons range from banal wear (especially on models older than 3 years) to moisture or dust under the body. But what if the phone freezes, does not respond to presses or does not turn on at all, and the power button does not work?

In this article, we’ll look at 5 proven ways to reboot without using a physical button, from software techniques to hardware tricks. Importantly, some require pre-tuning (e.g., USB debugging enabled), so if your Xiaomi still turns on, prepare it for possible crashes in advance. If your smartphone is completely dead, go straight to the emergency methods section.

Before you start, check:

• 🔋 Battery charge. Connect your phone to charge for 10 to 15 minutes -- sometimes a discharged battery blocks any action.
• 🔌 Cable and power supply. Try another cable/charging - a faulty accessory can simulate the "death" of the device.
• 💧 If your smartphone falls into the water, don't try to turn it on, bring it to the service right away.

Method 1: Software reboot via menu (if phone is on)

If your Xiaomi is on but the power button is not working, try rebooting it through the system menu first, which works on all models with MIUI 10 and later, including Redmi Note 10/11, POCO X3/X4, Mi 11/12, etc.

Instructions:

1. Open Settings (the gear icon on the main screen).
2. Scroll down and select About Phone.
3. Slip on Reboot (or Reboot the system on some firmware).
4. Confirm the action by pressing OK.

If this item is missing, try an alternative path:

• 📱 Hold the volume button. + lock button (yes, even if it doesn't work - sometimes a combination works).
• 🔄 In some models (for example, POCO F3) Reboot is available through Settings → Additionally. → Reboot.

⚠️ If after the reboot the power button did not work, do not try to disassemble the phone yourself - on most Xiaomi models, the battery is glued, and careless actions can damage the plumes.

Method 2: Reboot over ADB (for advanced users)

If your Xiaomi has enabled debugging on USB (setting for developers, you can restart it using your computer and utility ADB (Android Debug Bridge.This method is suitable for models that turn on but don't respond to the power button.

What you need:

• 🖥️ Computer with Windows/macOS/Linux.
• 🔌 USB-cable (preferably original).
• 📦 Installed Xiaomi drivers and package ADB Tools.

Step-by-step:

1. Download ADB Tools and unpack the archive.
2. Connect your phone to your PC and open the command line (Win + R → cmd).
3. Go to the folder with ADB command: cd path to folder\platform-tools
4. Enter the command to check the connection: adb devices If the device appears in the list, continue.
5. Do the reboot: adb reboot

If the team doesn’t work, try an alternative:

adb shell input keyevent 26

This command simulates the pressing of the power button.

⚠️ Attention: Teams ADB Do not use unknown commands from the Internet - this can lead to data loss or device blink.

Method 3: Reboot via Fastboot (if the phone doesn't turn on)

If your Xiaomi doesn’t respond to charging and doesn’t turn on, but when connected to a PC it’s defined as Qualcomm HS-USB QDLoader 9008 or the like, you can try rebooting it via Fastboot mode.This method requires an unlocked bootloader (it’s locked by default on most Xiaomi models).

Instructions:

1. Hold the volume button and connect the phone to the PC via USB.
2. Open the command line in the ADB folder and type: fastboot devices If the device is determined, continue.
3. Reboot: Fastboot reboot

If the phone is not identified, try:

• 🔌 Use the other USB-port (preferably) USB 2.0).
• 🔄 Reinstall Qualcomm drivers.
• 📱 Keep the combination Volume up + Power 10-15 seconds (sometimes even with a non-working button).

💡

Fastboot is a powerful tool, but the wrong commands (like fastboot erase) can erase data or lock your phone. Use only verified instructions!

Method 4: Emergency reboot via charging (for dead phones)

If your Xiaomi isn’t showing signs of life — it doesn’t vibrate, it doesn’t light up, it doesn’t detect the computer — try the forced discharge/charging method, which works thanks to the power controller features on Qualcomm and Mediatek chips that are used in most of the brand’s smartphones.

Algorithm of action:

1. Connect the phone to the original power supply (at least 18W).
2. Leave at least 30 minutes on the charge (even if the indicator is not on).
3. After 30 minutes, turn off the cable and wait 1 minute.
4. Connect the charge again and hold the volume button for 10-15 seconds.
5. If the Mi or Redmi logo appears, release the button and the phone should start downloading.

Why it works:

• 🔋 The power controller may block the on-off due to deep discharge or firmware failure.
• 🔄 The charging/discharge cycle sometimes resets the protection.
• 📱 On some models (e.g. Redmi) 9A) This method triggers emergency recovery mode.

⚠️ Warning: If after several attempts the phone has not turned on, do not continue experiments - this may indicate damage to the motherboard or battery dump.

💡

If you have a second Xiaomi phone, try using its charger – sometimes non-original power supplies don’t provide enough current to run a dead phone.

Method 5: Service codes for rebooting (hidden functions)

MIUI firmware has hidden service codes that allow you to reboot your phone without physical buttons, which don’t work on all models, but it’s worth a try — especially if other methods haven’t worked.

List of working codes:

• 🔄 Reboot: ##7325### (on some models).
• 📱 Hardware Test: ##4636## → In the menu, select Reboot.
• 🔋 Resetting power settings: ##76937## (can help if the button is not working due to software failure).

How to enter codes:

1. Open the Phone app.
2. Enter the code as a phone number.
3. If the code works, a menu with the option of rebooting will appear.

If the codes don't work:

• 📵 Check if they are blocked by the operator (relevant for some regions).
• 🔄 Try entering codes through Settings → The phone. → Version of the kernel (tap 5 times according to the kernel version).
• 📱 On new models (Xiaomi 13, Redmi Note 12) service codes can be disabled.

When is the time to bring your phone to service?

If none of these methods worked, it's probably a hardware problem, and here are the signs that it's time to call in the experts:

• 💥 The phone does not respond to charging, does not vibrate, does not warm.
• 🔧 The power button fuses or falls off (apparent mechanical damage).
• 💧 There were contact with water or severe blows.
• 🔋 The battery swelled (see on the raised screen or body).

The cost of repairing the power button on Xiaomi:

Where to repair:

• 🏢 Xiaomi service centers – 6-12 months warranty, but more expensive.
• 🔧 Local workshops are cheaper, but check reviews.
• 📦 Self-replacement – only if you have experience (on Redmi Note and the Redmi Note) POCO It is easier to replace the button than on the flagships Mi).

💡

If the phone is warranty, do not open it yourself - this will void warranty obligations.
