How to turn off Xiaomi if the screen is broken: effective ways

The situation when the display of the Xiaomi smartphone fails, but the device continues to function, is one of the most stressful for the owner. The screen can be completely black, but the phone vibrates, emits notifications or even heats up, at which point the user faces the urgent need to force the system to shut down to save battery power or prevent components from overheating.

The standard path through the settings menu is unfortunately unavailable, and it creates a sense of helplessness. However, Xiaomi engineers have provided several layers of device control that allow you to interact with the gadget even in the absence of a visual interface. Forced reboot or completely shut down is possible thanks to a combination of physical buttons, external accessories and debugging software tools.

In this article, we will take a look at all the available methods, from the simplest to the professional ones, how to use the mouse through the OTG adapter, how to use the capabilities of the Mi Cloud cloud service, and how to apply ADB console commands to power management, each of these techniques has its own nuances, depending on the model of your Xiaomi, Redmi or Poco.

Use of hardware button combinations

The most affordable and quick way to turn off a broken-screen smartphone is to use physical control buttons. Most modern Xiaomi models have a logic in which a prolonged pressing of the power button does not cause a switch-off menu, but immediately initiates a reboot or turn off the device if the software interface does not respond.

To implement this method, you need to find an on button, which is usually located on the right or left side of the case, press it and hold it for a long time. The standard interval is 10 to 20 seconds. If the screen is at least partially responsive or you feel tactile recoil (vibration), continue holding the button until the indicators completely fade.

In some cases, especially on older MIUI firmware or specific Android modifications, simple retention may not work right away. Then try a button combination. Press both the power button and the volume button. Hold them for about 15 seconds. This method is often used to enter Recovery Mode recovery mode, but on many devices it also works as a hardware reset that forcibly cuts power.

💡

If the phone vibrates but the screen remains black, try pressing the buttons for 30 seconds – this is guaranteed to drop static electricity and force the power controller to turn off.

It's important to understand the difference between software and hardware shutdowns. When you turn off your phone with buttons when the screen is broken, the system may not have time to save open documents or complete background processes correctly. It's a hard interrupt that's safe for hardware, but theoretically can affect the integrity of the file system when used frequently.

Management through USB-mouse OTG

One of the most effective and underrated ways to control a smartphone with a broken touchscreen is to use an external manipulator. Virtually all modern Xiaomi smartphones support OTG (On-The-Go) technology, which allows you to connect peripherals such as flash drives, keyboards and computer mice to a USB-C or Micro-USB port.

To implement this method, you will need an adapter. OTG (often comes complete with a phone or is inexpensive) and conventional wired USB-Connect the mouse to the adapter, and insert the adapter into the smartphone charging connector. If the device is on and the battery is not discharged to zero, the screen (even if it is broken, but shows the image) should show a cursor. If the screen is completely black, act on the touch or sound signals.

With a mouse cursor, you can try to reproduce the actions of your finger. Left-click at the intended location of the off button or swipe to unlock if the pattern lock is turned on. Even if the image is missing, connecting the mouse sometimes causes the system to voice the connection event or change the behavior of the LED indicator.

It is worth noting that not all adapters work equally with all models. Cheap Chinese adapters may not provide enough voltage or be incorrectly determined by the Xiaomi controller. If the cursor did not appear on the first attempt, try another adapter or connect the mouse through the mouse. USB-a hub with its own power, although it is rarely required to simply turn it off.

Forced shutdown via computer and ADB

For advanced users who have previously activated debugging mode USB (USB Debugging – The most powerful management tool opens in the “Developers” menu – Android Debug Bridge (ADB). This method allows you to send system commands directly, bypassing the graphical interface, which is ideal for a broken screen situation.

First, you need to install drivers for your device and platform. ADB to a computer with a Windows, macOS or Linux operating system. Connect your smartphone to a PC through high-quality USB-If a trusted connection to that computer was previously allowed on the phone screen, the connection will be established automatically, otherwise, even if the screen is broken, the command can pass if the permission was given earlier.

Open the command line or terminal in the folder with the ADB installed and enter the following command to check the connection:

adb devices

If a device with a device ID and status appears on the list, it means that the connection is established. Now, to turn off the phone, use the command:

adb shell reboot -p

This command initiates the shutdown process (power off). Alternatively, you can use the adb shell am start command. -a android.intent.action.POWER_USAGE_SUMMARY to go to the battery menu, from where you can sometimes initiate a shutdown, but a direct method with a flag -p more securely.

Android Security System Blocks Execution ADB-commands without prior user confirmation, which cannot be done on a broken touch screen.

Remote management via Mi Cloud and Find Device

Xiaomi’s ecosystem offers a built-in device search service that can be useful in critical situations. Find Device not only allows you to track geolocation, but also perform some actions with the gadget remotely if it is connected to the Internet.

Go to i.mi.com from any other device (computer, tablet or phone friend) log in to your Mi Account that was used on the broken smartphone. If the phone is online, you will see it on the map. The list of available actions often includes the option “Sound”, “Block” and sometimes “Data Clearup”.

While there may not be a direct “Switch Off” button in the web interface (for security reasons, so that an attacker cannot turn off a stolen phone), you can use the “Block” or “Clean Up” feature.

It is critical to have an active phone (Wi-Fi or mobile data) if the screen is so broken that you can’t see the network status, you can only hope for it if you are sure that the phone was online at the time of the breakdown.

Hardware Battery Shutdown (for Advanced)

If software methods are unavailable, buttons don't respond, and the phone continues to warm or consume energy, the only guaranteed way is to physically unblock the power circuit, a method that requires disassembling the device and is only suitable for those with minimal electronics skills.

In modern Xiaomi smartphones, the battery is connected to the motherboard via a connector. To turn off the phone, you need to remove the back cover (if it is glass or plastic and is heated / uncoupled) or dismantle the display module. After gaining access to the insides, you need to carefully disconnect the battery plume.

💡

Physically shutting down the battery is the only 100% way to stop the chemical processes and energy consumption if the phone’s electronics are hanging.

The following is a table showing the approximate time of operation of the various methods and their effectiveness:

When disassembling, be extremely careful. Lithium polymer batteries can ignite if damaged, use plastic blades and avoid using metal tools in the immediate vicinity of the battery. Once the plume is turned off, the phone is guaranteed to turn off.

Precautions and frequent errors

When trying to turn off a smartphone with a broken screen, users often make mistakes that can make things worse. The main mistake is trying to “cure” the screen with heating or freezing. Don’t put your phone in the freezer and heat it with a hair dryer in the hope that the touchscreen will “go away.” This can damage the adhesive elements of the case and moisture that gets inside through the cracks.

⚠️ Warning: Do not try to turn off the phone by sharply pulling the battery if the model is not removable.This can cause a voltage surge and damage the power controller. Use standard methods or turn off the train carefully.

Another common problem is ignoring overheating. If the phone in your pocket gets too hot and you can't turn it off, put it on a non-combustible surface (ceramic tiles, metal) away from flammable objects. Constant heating can cause the battery to bloat.

⚠️ Warning: If the phone continues to warm up even when it's off (when charging is connected), immediately disconnect it from the network.

Also, don't (too often) try to turn a device on and off with buttons if it's already gone out. Give the system time. Frequent on-off cycles with a damaged screen controller can lead to the final failure of the board.
