When Xiaomi’s favorite smartphone suddenly stops responding to the power button, it can disembark anyone, black screen, no vibration, and silence instead of the usual sound of the launch create a sense of hopelessness, but panic at this point is the worst solution, since in most cases the device must be restored without going to the service center.
The first thing you need to do is to assess the condition of the gadget, and often the problem is a simple battery discharge or a software failure of the MIUI or HyperOS operating system. Understanding what happened before the failure — a fall, moisture or the installation of a questionable application — will help to diagnose the cause more quickly.
In this article, we’ll look at all possible scenarios, from simple “revival” techniques to complex manipulations of system partitions, learn how to perform a forced reboot correctly, how to enter recovery mode, and what to do if the phone goes into Fastboot mode. Follow the instructions consistently to bring the device back to life.
Primary diagnosis and elimination of charging problems
The most common reason the phone doesn't turn on is because the lithium-ion battery is deep-discharged: If the device has been without power for a long time, the battery voltage may have dropped below a critical threshold, and the power controller blocks the start for protection.
You need to leave your smartphone on charge for at least 30 to 40 minutes, even if the charging indicator does not light up immediately.Use the original charger and cable, as third-party power supplies may not give enough current to "rock" the battery.
Carefully inspect the USB Type-C or Micro-USB connector. It often gets stuffed with dust, pocket pile and dirt, which prevents normal contact. Carefully, without using metal objects, clean the port to eliminate mechanical obstruction to charging.
⚠️ Warning: If Xiaomi’s phone starts to heat up in the battery or processor area during charging, disconnect it immediately from the grid.
Try using a different cable and a different power adapter to rule out malfunctioning. Sometimes the problem lies in the accessories, not in the smartphone itself. If after 40 minutes of charging there are no signs of life, move on to the following methods.
💡
Use a Quick Charge or Power Delivery-enabled charger to quickly raise the battery voltage to the working level.
The method of forced reset (Hard Reset buttons)
If Android is stuck at the kernel level, a simple power button press may not work, and in such cases, a technique known as hard reset buttons or forced reboot helps, a method that is data-safe and does not delete information from the device.
To perform this procedure, you need to press the power button and hold it for a long time - from 10 to 20 seconds. Some Xiaomi Redmi or Poco models require simultaneous pressing of the power button and the volume button.
Keep the buttons pinched until you feel the vibration or see the Mi logo. If the screen blinks and goes out, release the buttons and wait. This process resets static electricity and restarts the controllers.
- 🔘 Press the power button for 15-20 seconds.
- 🔘 If it doesn’t work, then press the “food” button» + «Loudness down" at the same time.
- 🔘 Hold the combination until a vibration or logo appears.
- 🔘 Release the buttons immediately after the screen reaction.
Often users release buttons too early without waiting for the system to react. Be patient and keep the combination firmly clamped. If after 20 seconds nothing has happened, repeat the procedure 2-3 times at intervals per minute.
💡
Forced reboot doesn’t delete your photos and contacts, it’s the equivalent of taking out the battery in old phones.
Diagnostics through Fastboot mode
Fastboot mode is a special diagnostic mode built into the bootloader of most Android devices. If the Xiaomi phone doesn't turn on in the usual way, but reacts by logging in to Fastboot, that's good news: the hardware is most likely working.
To enter this mode, you need to turn off the phone (if it reacts) and press the power button along with the volume button. The screen should show an image of a rabbit repairing an android, labeled FASTBOOT. If you see this screen, then the display and the main controllers are working.
Being in this mode allows you to reflash the device through the computer or simply exit it if you entered by accident. To exit the Fastboot, you usually just need to press the power button and hold it for about 10-15 seconds until the phone vibrates and reboots.
| Symptoms. | Possible cause | Action. |
|---|---|---|
| Black screen, no reaction | Deep discharge or plume breakdown | Long-term charging, plume check |
| Hanging on the Mi logo | Software failure or damage to system files | Entering Recovery, Resetting or Firming |
| A hare appears (Fastboot) | Accidental button pressing or loader failure | Holding the power button 15 seconds |
| Phone vibrates, screen black | Display or backlight malfunction | Checking through connection to PC (USB sound) |
If the phone itself goes into Fastboot mode every time you turn on, it could indicate that the volume buttons are stuck or the button plume is damaged, requiring disassembly and inspection of internal components.

Using the Recovery Menu to Reset Settings
If standard methods didn’t work, use the Recovery Mode Recovery Menu, a built-in smartphone maintenance tool that lets you reset to factory settings or try to reinstall the system.
To enter Recovery on a phone that is off, press the power button and the volume button. When the Mi logo appears, release the power button, but keep holding the volume button until the menu appears. In newer versions of MIUI, the menu can be touch-sensitive.
⚠️ Note: Performing a Wipe Data reset in the Recovery menu will result in the total loss of all photos, contacts and applications. Use this method only if the data is not important or already stored in the cloud.
From the menu, select Wipe Data, then confirm the action. Once the process is complete, select Reboot to restart, which eliminates software conflicts that may have blocked the system from starting.
If the phone doesn’t turn on or freezes on the logo after the reset, the problem may be deeper, such as damage to the system partition or a physical memory malfunction, in which case a complete flashing through the PC will be required.
- 📱 Hold the "Food» + «Volume up" before menu appears.
- 🗑️ Select Wipe Data for a complete reset.
- 🔄 Press Reboot to restart the system.
- 💾 If you have a Connect with MIAssistant, you can try connecting to a PC.
Sometimes, you can't log in to Recovery because of a damaged bootloader, in which case the screen will remain black or the phone will only react with vibration. Don't try to disassemble the device if you don't have experience.
☑️ Checklist before data reset
Analysis of the behavior of the charging and vibration indicator
The behavior of the LED indicator and the presence of vibration can tell a lot about the state of the Xiaomi smartphone. If the red indicator lights up when connecting the charging, but the phone does not turn on, this suggests that the power chain is intact, but the system cannot start.
The lack of a response indicator when connected to the charger often indicates a malfunction of the power controller, the charging connector or the battery itself. In modern models with non-removable batteries, replacing the battery requires special tools.
If the phone vibrates when connected to the computer (produces a characteristic sound) USB-Windows connection, but the screen remains black, perhaps the display plume or the matrix itself has burned. Try gently pressing different parts of the screen or slightly curve the case (no fanaticism) to check the contact of the plume.
In some cases, the knocking method (very carefully) helps on the back cover in the camera area, as there is often a plume of the main module that could move away when falling.
If you have a vibration but the screen is black, try calling the number from this phone, and if it's ringing, it means the device is working, and the problem is only in the display, which confirms that the screen needs to be replaced.
💡
Connect your phone to your computer and listen to the sound of the device's connection, and if there's sound and the screen is black, it's probably the display, not the hardware.
When you need to go to the service center
There are a number of situations where software recovery methods are powerless: If a Xiaomi phone does not turn on after falling into the water, even if it has been in rice for several days, there is a risk of corrosion of contacts on the board.
Also, the reason for contacting specialists is a situation when the phone is very hot when it is switched off when connecting to charging, which is a sure sign of a short circuit in the power supply or a battery failure.
If you've done all the steps: long charging, hard reset, Fastboot and Recovery login, but the device still shows a brick, the problem lies in the hardware. It could be a failure of the processor, memory or power controller.
Self-repairing can lead to permanent failure of the device, and professionals use microscopes, ultrasound baths and programmers to diagnose and repair circuits.
⚠️ Attention: Opening the case of the Xiaomi phone on your own often leads to a loss of warranty.If the device is warranty, carry it to an authorized center immediately.
If the back cover of the phone has moved away or the screen has started to push out of the frame, the battery should be changed immediately, as it is fire-prone.
