How to restart Xiaomi smartphone if the power button does not work: all working methods

A broken power button on Xiaomi is one of the most frustrating breakdowns that can completely paralyze a smartphone. Without the ability to physically press a key, users face problems: the phone does not turn off, does not reboot, and sometimes even freezes on the lock screen. But do not rush to carry the device to the service center, in 90% of cases, the reboot can be performed software or using alternative hardware methods.

In this article, we will discuss all the current ways to reboot for Xiaomi, Redmi and POCO smartphones, including models with MIUI 12/13/14 and Android 11/12/13/14. From simple software solutions to emergency measures, you will learn how to regain control of the device even without a power button working.

Why Xiaomi’s power button may not work

Before we go into reboots, it's important to understand the cause of the malfunction, which will help you choose the most effective method and avoid the problem from getting worse.

• 🔋 Mechanical damage – the button stuck, the contact fell off, or the microswitch broke (often after falling or getting moisture).
• 💻 Software failure – the system does not recognize the pressings due to errors in the MIUI or drivers (for example, after a failed update).
• 🔌 Power problems – a discharged battery or faulty charging controller blocks the response to a button.
• 🛠️ After repair – if you recently changed the display, battery or motherboard, could damage the plume of the button.

If the button sometimes works (for example, with a strong press or at a certain angle), the problem is more mechanical, if it does not respond at all, it is the software or a complete contact break, in the latter case, you can not do without disassembling the device, but you can still restart the phone.

Method 1: Reboot via MIUI menu (if phone is on)

The easiest method is to use the built-in MIUI features. It is suitable if the smartphone screen is working and the power button does not respond only to hold (for example, to call the reset menu).

Instructions:

1. Open the settings (cog icon on the desktop).
2. Go to About Phone (in some versions of MIUI – About Device).
3. Slip on the item Reboot (or turn off if you need a complete disconnect).
4. Confirm the action in the window that appears.

If your MIUI version does not have a “Reboot” option, use an alternative path:

• 📱 Open the Notification Panel (swipe down from the top edge of the screen).
• 🔄 Find the Reboot icon (if it is not, tap the icon). ⚙️ Settings in the upper right corner of the panel).

Close all important applications|Connect the charge (if the battery is discharged)|Keep open files.|Make sure that SIM-card not blocked-->

Note: Some models (e.g., POCO F3 or Redmi Note 10 Pro) may have a mode-selected menu (Normal Reboot, Safe Mode, Recovery) after clicking "Reboot."

Method 2: Forced reboot via charger

If the phone doesn't respond to touch (the screen is black, but the device is warm), you can try to wake it up with a charger, which works because when the power is connected, the charging controller is activated, which can initiate a restart of the system.

Step-by-step:

1. Connect your smartphone to the original charger (it is better to use the power supply from Xiaomi at 18-33 watts).
2. Wait 10-15 seconds – sometimes the phone turns on or shows the charging indicator.
3. If the screen remains black, hold the Volume Up button for 20-30 seconds, which will cause a forced reboot on some models.
4. If nothing happens, turn off the charging, wait 5 seconds and reconnect.

If the battery is completely discharged (below 3%), this method will not work – you first need to recharge the phone to at least 5-10%.

Method 3: Using Fastboot Mode (for Power Users)

If the phone turns on, but the power button doesn't work even for short-term presses, you can reboot it through Fastboot, a special mode for firmware and diagnostics. USB-cable, but suitable even for completely dead screens (if the device is determined by the PC).

What you need:

• 🖥️ Computer with Windows/macOS/Linux.
• 🔌 Cable USB Type-C (preferably original).
• 🛠️ Utility. ADB & Fastboot Tools (you can download from the official Android website).

Instructions:

1. Connect the phone to the computer.
2. Open the Command Prompt (cmd) or Terminal.
3. Enter the command to check the connection: fastboot devices If the device is determined (its serial number appears), move to the next step. If not, try another cable or USB port.
4. Run the reboot command: fastboot reboot

If the phone is not detected in Fastboot, try to manually convert it to this mode:

• 🔕 Turn off the device (if it still works, use Method 1).
• 🔊 Hold Volume Down + Power (if the power button does not work at all, this method will not work).

💡

If the phone doesn’t restart after the fastboot reboot command, try fastboot reboot recovery – this will load it into recovery mode, from where you can select the restart option.

Method 4: Battery Removal (for older models with removable battery)

On Xiaomi smartphones before 2017-2018 (e.g. Redmi 4A, Redmi Note 3, Mi 5), the battery was removable, and if you have this model, the most reliable way to reboot is to physically shut down the power.

How to do this:

1. Turn off your phone (if it still responds to touch).
2. Remove the back cover (a plastic shoulder blade or mediator will be required).
3. Carefully disconnect the battery plume or remove it completely.
4. Wait 30 to 60 seconds (this will reset the residual charge of the capacitors).
5. Install the battery back and turn on the phone with the power button (if it works even a little) or through charging (Method 2).

⚠️ Note: New models (Redmi Note 10, POCO X3, Xiaomi 12 and newer) the battery is non-removable, and trying to remove it without special skills will damage the plume or blow up the battery!

If you are not sure if the removable battery in your model, check the table:

Method 5: Emergency reboot via ADB (no power button)

If the phone is on, but the power button doesn't work even for short-term taps, and the Fastboot isn't available, you can use ADB (Android Debug Bridge), which requires pre-activating USB Debugging in the developer's settings.

Important: If you’ve never enabled USB debugging, this method won’t work!

Instructions:

1. Connect the phone to your computer and confirm your trust in the device (if you receive a request).
2. Open the Command Prompt in the ADB folder.
3. Enter the command to check the connection: Adb devices should appear serial number of your Xiaomi.
4. Do the reboot: adb reboot

If you need to reboot to Recovery (for example, to reset settings), use:

adb reboot recovery

⚠️ Note: After rebooting through ADB You may need to re-enable the debugging USB. If the lock screen is on, unlock the phone manually (for example, through a fingerprint or a fingerprint). PIN-code).

💡

If ADB Does not see the device, check the drivers (install Mi) PC Suite and try another one USB-On Windows, sometimes it helps to disable the driver signature.

What to do if nothing helps: hardware solutions

If none of the software methods worked, the problem is probably hardware, and in this case, there are three options:

• 🔧 Power button repairs -- microswitch or plume replacements, 800 to 2,500. ₽ model-wise.
• 🔋 Connection through test points – experienced masters can close contacts on the board, simulating the push of a button (temporary solution).
• 📱 Replacement of the motherboard is the last resort if the power controller is damaged. Cost: from 5000 ₽.

Before you bring your phone to the service, try diagnosing the problem yourself:

• 🔍 Light a flashlight on the button – if it shows dirt or oxidation, it can be cleaned with alcohol.
• 🎵 Connect your headphones and check if your phone is responding to other buttons (volume, lock.
• 🔋 Try charging your phone with another cable - sometimes "glitch" buttons are associated with unstable power supply.

If you decide to repair the device yourself, consider:

• 🛒 Xiaomi is better off buying parts on AliExpress (sellers rated 98%+) or in trusted stores (for example, MegaFon Shop, Connected).
• 🔧 For analysis you will need: plastic spatula, sucker, tweezers and hair dryer (to soften the glue).
• 📹 Before disassembling, watch the video instructions for your model - the location of the plumes may differ.

How to avoid repeated problems with the power button

If you can reboot Xiaomi without a power button, take care to prevent the problem from recurring.

• 🚫 Avoid mechanical stress – do not put your phone in your pocket with your keys, do not press the button with dirty or wet hands.
• 🔄 Regularly update the software in new versions MIUI Frequently fixing food management bugs.
• 🔋 Watch the battery – if the phone suddenly turns off at 20-30% charge, the battery needs to be replaced (a discharged battery can cause button failures).
• 🛡️ Use a case with a cutout under the button - this will protect it from accidental pressing and dust.

If the button has already started to “glue”, but still works, you can extend its life:

• 🧴 Wipe the area around the button with isopropyl alcohol (at least 90%) – this will remove oxides.
• 🔊 Set up program buttons (for example, double tap to wake up in Settings) → Lock screen).
• 🔄 Enable automatic reboot on schedule (in Settings) → Additionally. → Planner).

Important: If the power button stopped working after falling or getting moisture, do not pull with repair - over time, oxidation can spread to other components of the board.
