Why is the standard shutdown not working?
Broken screen on Xiaomi is a stressful situation, especially if the sensor does not respond to touch. Even if the display shows the image partially, the standard hold of the power button may not work: the system simply does not recognize your press due to a damaged glass layer. In the worst case, the screen is completely black, and you can not even see if the phone is on.
Compounding the problem, many users fear damaging data or causing a faulty shutdown, and if the battery is less than 15% dead, a sudden power outage can cause the file system to crash, but there are proven methods that minimize the risks.
In this article, we will look at all possible scenarios, from the simplest hardware shutdown to the use of ADB and service codes. Importantly, if the screen is not just cracked, but fluid oozes from under the glass (a sign of battery damage), immediately stop all manipulation and contact the service center - it is life-threatening!
Method 1: Hardware shutdown with buttons
The most versatile method, which works on 90% of Xiaomi models (including Redmi Note 10/11/12, POCO F3/F4, Mi 11/12). It does not require a PC connection or special knowledge.
Algorithm of action:
- Hold the power button + volume button at the same time for 10-15 seconds.
- If the phone vibrates or the screen flashes, release the buttons. This is a signal to start turning off.
- Wait 30 to 60 seconds for the device to shut down completely.
⚠️ Note: On some models (e.g. Xiaomi 13 Pro), this combination can start the Fastboot instead of turning it off. If you hear vibrations but the screen doesn't go out, try holding the power button for 20 to 25 seconds.
☑️ Pre-off check
Method 2: Use of service codes (if the screen is partially running)
If the display display displays a little bit of the picture, you can try to enter a service code to force the shutdown, which is suitable for devices on MIUI 12/13/14.
Instructions:
- Open the phone app (if the sensor is in one zone).
- Enter the code ##7780## (reset to factory settings without deleting data).
- Confirm the action if a request appears.
⚠️ Warning: Some firmware may not work with this code. Alternatively, ##4636## (test menu), where Power off is sometimes available in the Battery information section.
| Code. | Action. | Works for MIUI. |
|---|---|---|
| ##7780## | Soft reset (saves data) | 12, 13, 14 |
| ##4636## | Test menu (sometimes there is an option to turn off) | 11–14 |
| ##284## | Sensor test (can help if the screen is partially responsive) | 10–13 |
Method 3: Disconnect via ADB (for advanced users)
If you've previously had Developer Mode and USB Debugging enabled, you can turn your phone off via your computer, which requires pre-setting, but it's 100% effective.
Step-by-step:
- Connect your phone to your PC through USB-cable.
- Open the Command Prompt (Windows) or Terminal (macOS/Linux).
- Enter the command: adb devices If the device is defined, execute: adb shell reboot -p
⚠️ Note: If adb devices returns an empty list, then debugging is the best way to do it. USB It wasn't activated beforehand, and it won't work.
What if the ADB can’t see the device?
Method 4: Removal of the battery (extreme case)
If no software method works, there is a physical power outage, which is the only way to guarantee Xiaomi to turn off with a completely idle screen and a locked bootloader, but it requires disassembling the device.
What you need:
- 🔧 Plastic blade or mediator
- 🔩 Cross screwdriver (usually) PH00)
- 🧲 Suction (for models with glass back cover)
- 🔋 Thin gloves (the battery may be deformed)
Sequence of action:
- Heat the back cover with a hair dryer (60–70°C) around the perimeter to soften the glue.
- Tap the lid with a plastic spatula, starting at the corner next to the power button.
- Unscrew the screws that fix the metal plate of the battery.
- Carefully disconnect the battery plume (don't pull the wires!).
⚠️ Warning: If the battery is blown up (the cover is raised), do not try to remove it yourself - risk of fire! In this case, wrap the phone in foil and take it to the service.
💡
Before disassembling, take a picture of the location of the screws and plumes, which will help to properly assemble the device back.
Method 5: Contacting a Service Center
If you are not confident or the phone is on warranty, the best way to go is to contact professionals. Xiaomi has official service centers in most major cities. The cost of turning off the device (without repairing the screen) is usually 300-800 rubles, depending on the model.
What to say to the master:
- 📱 Please note that you only need soft reset (off), not a complete flashing.
- 🔋 Ask to check the battery for bloating (it's free).
- 📁 Find out if it is possible to save data before turning it off (sometimes it helps). EDL-regime).
⚠️ Note: If the phone was purchased less than a year ago, the repair warranty can cover the replacement screen (provided the damage is not mechanical).
What do I do after the shutdown?
When the finalmente phone is turned off, the question is, what's next? Here's a checklist of actions depending on your situation:
| Purpose | Action | Tools |
|---|---|---|
| Save the data | Connect to your PC via Fastboot or EDL, use the Mi Flash Tool | USB-cable, PC, firmware |
| Replace the screen | Buy the original display (check the article by model), disassemble the phone | Screwdriver, spatula, hairdryer. |
| Sell for spare parts | Check the performance of the camera, speakers, microphone | Test, multimeter |
If you plan to repair your phone yourself, be sure to check out the disassembly of your model on YouTube - Xiaomi design can be very different even within the same line. For example, in the Redmi Note 12, the battery is glued stronger than in the POCO X3, and the plumes are thinner.
💡
Never turn on a phone with a broken screen if you see sparks or smoke from under the glass.This is a sign of a short circuit - immediately isolate the device!
