How to completely disable the smartphone Xiaomi Poco X3: 5 ways with explanations

Xiaomi Poco X3 is a popular smartphone with advanced power management features, but not all users know how to turn it off correctly without risk to the system. Unlike classic button phones, modern devices on MIUI require several nuances to consider: from forced shutdown when hanging to correct termination of background processes. This article will help you understand all available methods, from standard shutdown to emergency scenarios when the smartphone does not respond to commands.

The Poco X3 (M2007J20CG and M2007J20CI) features optimized power consumption that can interfere with the usual shutdown through a long press of the power button. For example, if the Quick Start function is activated in the battery settings, the smartphone can go into deep sleep instead of turning off. We will discuss in detail how to circumvent these restrictions and what to do if the device hovers on the POCO logo or the screen becomes black after a failed firmware.

Standard shutdown via the power menu

The safest and most recommended way is to use a regular shutdown menu, which is suitable for most situations where the smartphone is stable and responsive to pressing.

1. Press and hold the power button (located on the right end of the body) for 2-3 seconds.
2. The screen will appear menu with three options: "Switch off", "Reboot" and "Emergency mode".
3. Tap the "Switch off" item and confirm the action by pressing "OK" in the dialog window that appears.

If the menu doesn't appear, check if Double-click to wake up is activated in Settings → Screen → Lock and Protection. It may conflict with long-press processing. Also make sure that the power button is not hit by moisture or dirt - this is a common cause of mechanical elements malfunctioning.

💡

If the smartphone doesn't respond to the first press, try repeating the action with the charger connected. Sometimes low battery power blocks access to the power menu.

• ✅ Pros of the method: safe for the system, saves all data, does not require additional knowledge.
• ⚠️ Cons: Does not work when the interface freezes or hardware failures of the power button.
• 🔄 Alternative: You can turn off the device through Settings → The phone. → Turn off (the path is relevant for) MIUI 12–14).

Forced shutdown when getting stuck

If the Poco X3 stopped responding to touch, the screen stopped in one image or endless download animations appeared, a hard reset would be required – a technique that mimics battery extraction, but on modern smartphones with a fixed battery, it is performed with a combination of buttons.

Instructions for forced disconnection:

1. Press and hold the power button + volume button at the same time.


2. Keep them clamped for 10-15 seconds (before vibration or screen shutdown).




3. After switching off, wait 30 seconds before re-energizing.

Poco X3 models with MIUI 13+ firmware may need to hold buttons for up to 20 seconds – this is due to optimizing the Android 11/12 kernel to protect against accidental reboots. If the smartphone doesn’t turn on after being forced to turn off, plug it into charging for 10-15 minutes, and then try again.

⚠️ Attention: Frequent use of forced shutdown can cause damage to the file system (especially if you interrupt the recording of data on flash memory). DCIM and downloads.

Turning off via Recovery Mode

If the smartphone is turned on but does not load beyond the POCO logo, or you need to reset before selling, you can use Recovery mode. This method is also useful if you forget the pattern lock or lock password.

Step-by-step:

1. Turn off your smartphone (forced if it freezes).
2. Press the power button + volume button at the same time.
3. Hold them until the Mi Recovery logo appears (usually 5-8 seconds).
4. In the Recovery menu, select "Reboot → Power Off" with the volume buttons.
5. Confirm the choice of the power button.

Recovery Mode also offers options for Wipe Data resets or Wipe Cache cleaning. Careful: choosing Wipe Data will delete all user data, including photos and apps!

Disconnecting via ADB (for advanced users)

The Android Debug Bridge (ADB) method is suitable for those with USB debugging enabled and computer access, which is useful if the physical buttons don't work, but the smartphone is determined by the PC.

Instructions:

1. Get Poco on. X3 computer-to-computer USB-Cable (original or certified).
2. Open the command line (Windows) or terminal (macOS/Linux) in the adb folder.
3. Enter the command to check the connection: adb devices must appear serial number of the device.
4. Execute the shutdown command: adb shell reboot -p

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

adb shell input keyevent 26 # Simulating the power button


adb shell input keyevent 4 # Return to the menu (if necessary)

⚠️ Attention: Use ADB Requires prior activation of the debugging USB In Settings → The phone. → Version. MIUI (7 times press to unlock the developer menu. Without this, commands will not be executed.

Automatic shutdown on schedule

The MIUI Auto Shutdown feature allows you to schedule a smartphone shutdown at a specific time, which is convenient if you want to limit your device usage time (e.g., before bedtime) or save battery power.

How to set up:

1. Go to Settings → Battery and Performance → Schedule off / on.
2. Activate the "Automatic Shutdown" slider.
3. Set the time and days of the week when the smartphone should turn off.
4. Press Save.

Note that this feature only works when connected to charging (if you select the option "Only when charging"), and it can conflict with the "Do Not Disturb" mode if it has exceptions for alarms or notifications.

Frequent Mistakes and How to Avoid Them

Even when following instructions, users often encounter problems, and here are the most common mistakes and ways to solve them:

• 🔋 "The smartphone does not turn on after switching off – check the battery charge (plug in for 10-15 minutes) or try to press the power button at 20+ seconds to reset the power controller.
• 🔄 "Permanent reboots after forced shutdown are a sign of damage to system files. Solution: Reset settings via Recovery or reflash the device.
• 📱 "Power button not working" - if mechanical damage is ruled out, try turning on your smartphone via charging connection or use ADB (if the debugging has been included previously).
• ⚡ "Fast Discharge After Shutdown – Turn off Quick Start in Battery Settings and check apps in the background via Settings → Annexes → Permits → Auto-start.

Preventive tip: Once a month, perform a soft reset (turn off for 5-10 minutes) to clean RAM. This is especially true for the Poco X3 with 6 GB of RAM, where background processes can accumulate and slow down the system.
