How to turn off Xiaomi smartphone without a power button: the full guide

Why the power button stops working and what to do about it

The on/off button on Xiaomi smartphones is one of the most vulnerable elements. It fails due to mechanical wear, moisture, falls or factory defects. According to service centers, up to 15% of Redmi, POCO and Mi repairs are due to a malfunction of this button. But what if the phone needs to be turned off immediately and the button does not respond?

In this article, we’ll look at 5 proven ways to turn off Xiaomi without a power button, from standard MIUI features to technical tricks with ADB and battery. Importantly, some methods require pre-tuning or disassembling the device, so choose the right one based on your situation.

If the button breaks suddenly and the phone is down to 1-5%, connect it to charging first. Sometimes the device automatically shuts down at a critical charge level - this can save time finding alternative solutions.

Method 1: Turn off via the settings menu (if the screen is running)

The easiest and safest method is to use the built-in MIUI functions, which is suitable if the smartphone screen is working and the power button is not pressed.

1. Open “Settings” (the gear icon on the home screen or in the application menu).
2. Go to About Phone (in some versions of System → About Phone).
3. Slip on the item "Switch off" or "Reboot" (on POCO and the new Redmi can be called "Switch off" power).
4. Confirm the action by selecting Turn off in the window that appears.

If this is not the case, try an alternative route:

• 🔄 Pressing the lock button for a long time (even if it doesn’t work physically, sometimes it helps to hold the area around it with your palm).
• 📱 Power widget: add power management widget to the main screen (available on the MIUI 12+).
• 🔋 Developer Mode: Activate the Option Off in the Power Menu in the Developer Settings (how to enable – see the next section).

⚠️ Note: If your smartphone is locked with a password and the power button is not working, this method will not work. ADB or battery-extracting.

Method 2: Using Developer Mode and ADB

For advanced users, there is a way to turn Xiaomi off via Android Debug Bridge (ADB), a method that requires pre-setting, but works even on locked devices (if USB debugging was previously enabled).

If the USB debugging is already activated:

1. Connect your smartphone to your PC through USB-cable.
2. Open the command line (Windows) or the terminal (macOS/Linux).
3. Enter the command: adb shell reboot -p It will instantly turn off the device.

If USB debugging is not enabled, but the screen is running:

1. Activate Developer Mode: Go to Settings → About Phone and tap the MIUI version 7 times.
2. Return to Settings → Additional → For developers and enable USB debugging.
3. Connect to your PC and execute the command adb shell reboot -p.

⚠️ Attention: Adb shell reboot command -p It doesn't work on all firmware. It works on some devices (e.g., some devices, POCO F1 with custom firmware) root rights may be required, which voids the warranty.

Method 3: Forced shutdown through battery

If the screen doesn’t respond and the power button breaks, the mechanical way is to turn off the battery, a method that is suitable for most Xiaomi models, except for flagships with non-removable batteries (for example, the Mi 11 or Redmi K50).

Instructions for removable battery devices (Redmi 4A, Redmi 5A, POCO M2, etc.):

1. Remove the back cover (a mediator or plastic card will be required).
2. Carefully disconnect the battery plume or remove the battery (on some models it is glued – do not pull force!).
3. Wait 30 seconds and reconnect the battery.

For non-removable battery devices (Mi 9, Redmi Note 10 and later):

• 🔧 Disassembly: a screwdriver will be required T3/T4 And experience with electronics. Disconnect the battery plume from the motherboard.
• 🔋 Discharge: if you can not disassemble the phone, wait for the full discharge (may take several days with the screen turned off).
• ⚡ Short circuit: An emergency method for power users is to short-term close the contacts of the battery (risk of damage to the board!).

💡

Before disassembling, take a picture of the location of the plumes and screws - this will help to assemble the device back without errors.

⚠️ Warning: Disassembly of the smartphone voids the warranty. If the device is warranty, contact the service center Xiaomi - repair power button will cost less than recovery after a failed disassembly.

Method 4: Turn off via Recovery Mode (if the button is partially working)

If the power button responds to a long press (for example, it turns on the off menu, but does not confirm the action), you can try to log in to Recovery Mode and turn off the device from there.

Instructions:

1. Press the button combination: For most models: Volume up + Power (hold 10-15 seconds). For POCO: Volume up + Volume down + Power.

Recovery

Power Off

Shutdown

Confirm the choice of the power button (if it works even a little) or wait for the automatic shutdown.

If the Recovery menu is in Chinese:

• 📛 First paragraph - (Reboot).
• 🔌 Second or third item (Power Off).
• 🛠 Last item is Wipe Data (don’t choose it unless you want to reset your settings!).

💡

Log in Recovery Mode only erases data if you have selected Wipe Data. Simply turning off through this menu is safe.

Method 5: Emergency Methods (for experienced users)

If none of the above methods work, there are extreme measures that require technical skills and can damage the device, so only use them in a desperate situation.

Method 1: Short-circuit of the power button contacts

On the smartphone motherboard, there are power button contacts, and if you close them carefully with tweezers or screwdrivers, the device can react as if you press them. 9 and similar models contacts are located next to the battery connector - they can be found by marking PWR_SW.

Method 2: Use of Test Menu (Engineer Mode)

Some Xiaomi models support a hidden engineering menu to get there:

1. Dial the number on the keyboard: ##4636##.
2. Go to the Battery Information section.
3. Click on the menu icon (three dots) and select Shutdown.

Method 3: Connecting to a non-standard voltage power source

If the battery is completely discharged, some craftsmen use a laboratory power supply with a voltage of 3.7-4.2V, connected directly to the contacts of the battery. When the power is applied, the device can turn on, then it can be turned off through the menu.

💡

Before using emergency methods, try to leave your phone on charge for 1-2 hours, sometimes after recharging the power button temporarily "resurfaces" due to the restoration of contacts.
