Your Xiaomi has stopped responding to the power button, the screen is black, and the charging indicator shows no signs of life? This problem is familiar to many owners of Redmi, POCO or Black Shark smartphones - from budget models to flagships. In 70% of cases, the device can be "resuscitated" yourself, but to do this, you need to accurately determine the cause of the malfunction.
We analyzed hundreds of calls to service centers and forums (including 4PDA, Mi Community, and XDA-Developers) and identified 10 key reasons why Xiaomi’s smartphone might not turn on, some of which are due to software failures (for example, after the MIUI update), others to hardware breakdowns (a disconnected plume, a bloated battery).
- 🔋 Diagnosis by symptoms (vibration is / no, the indicator flashes / does not blink, etc.)
- 🛠️ Step-by-step instructions for each case (with photos and commands for the ADB/Fastboot)
- ⚠️ Warnings that will prevent the problem from worsening (for example, why you can not connect charging from the iPhone)
- 💰 Cost of repairs in services (current for 2026)
1.Discharged battery or charging problems
The most obvious but often overlooked reason is that even if you “just” charged your phone, the battery could run as low as 0% in 10-15 minutes due to short circuit or power controller failure, especially for Xiaomi models aged 2+ years (Redmi Note 5/6/7, Mi 8/9).
How to check:
- 🔌 Connect the original cable and power supply (at least) 18W Try another socket socket for quick charging.
- ⏳ Leave your phone charging for at least 30 minutes – sometimes the indicator doesn’t light up right away.
- 🔄 Try charging from another device (laptop, power bank) – this will help eliminate the problem with the socket.
- 🔍 Light a flashlight on the screen at an angle - sometimes the image is, but the backlight does not work.
If the charging indicator flashes red or burns white, but the phone does not turn on:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Red indicator flashes 1 time in 2 seconds | Critically low charge (<5%) | Charge 1-2 hours with the original ZU |
| The red light is constantly on. | Charging is going on, but slowly (unoriginal cable) | Replace the cable/power supply |
| White indicator flashing | Firmware failure or hardware breakdown | Try Hard Reset (see Section 3) |
| The light doesn’t burn, but the phone is warming. | Short circuit in the battery | Shut down the network immediately! |
⚠️ Warning: Never use Apple or Samsung chargers for Xiaomi - they have a different current distribution scheme.This can cause the battery to bloat or damage to the power controller.
System freeze (software failure)
If the Xiaomi phone is stuck on the MIUI logo, reboots cyclically or doesn’t respond to buttons, the problem is likely software.
- 📱 Failed update MIUI (especially in beta versions)
- 🧩 Conflict after installing custom recovery (TWRP)
- 🗑️ Overflow of memory (less than 500 MB of free space)
- 🛡️ Blocking with antivirus or Google Play Protect
How to fix it:
- Forced reboot: Press the power + Volume Up button for 10-15 seconds. For some models (POCO F3, Redmi K40) you need to hold Volume Down.
- Safe Mode: When turned on, hold Volume Down until the Safe Mode sign appears.In this mode, remove newly installed apps.
- Reset via Recovery: 1. Turn off your phone (if you don't respond, wait for the battery to drain). 2. Press Volume Up + Power before the Mi. 3 logo appears. Select Wipe Data → Wipe All Data.
What if the sensor in Recovery is not working?
If the reset didn’t help and the phone is still stuck on the logo, flashing through Fastboot will be required (see Section 5).
☑️ Preparing for resetting through Recovery
3. Hardware breakdowns: from battery to motherboard
If the phone doesn't show signs of life (no vibration, no light, no heat), the problem is almost certainly hardware.
1. Bloating or failure of the battery
Symptoms: the case of the Xiaomi phone is “inflated”, the screen is raised, when you press the back cover you can hear a crunch. Xiaomi batteries last an average of 2-3 years, after which they begin to degrade, especially vulnerable models with a capacity of 5000+ mAh (Redmi Note 10 Pro, POCO X3 Pro).
2. Damage to the power plume or display
A common problem after falls: the plume can come off partially — for example, the phone vibrates when you press a button, but the screen remains black. You can only diagnose when you disassemble.
3. Short circuit on the motherboard
It happens after moisture, bad soldering or a power surge, symptoms: the phone warms even when it's off, the smell of burning, traces of oxidation on the board.
4. Power button malfunction
If the phone is responding to charging (the indicator is on), but does not turn on when you press the button, the problem may be in the micro-switch. Check if the volume button is working - if so, then power is supplied.
| Breakdown | Cost of repair (2026) | Can I do it myself? |
|---|---|---|
| Battery replacement | 1 500–3 000 ₽ | Yes (with tools available) |
| Replacement of the display plume | 2 000–4 500 ₽ | Difficult (needs ration experience) |
| Maternity board repair | 5 000–15 000 ₽ | No (professional equipment required) |
| Replacement of the power button | 1 000–2 500 ₽ | Yeah (needs fine tweezers) |
⚠️ Warning: If the phone falls into water or has been subjected to severe vibration (for example, in a car without a mount), do not try to turn it on.
💡
Before disassembling the phone, take a picture of the location of all the plumes and screws - this will help to collect it back without "extra" details.
4 Problems after MIUI Update
MIUI updates sometimes lead to a phone bric (completely inoperable) and are particularly risky:
- 📲 Transition from Android 10 → Android 11/12 (For example, on the Redmi Note. 8 Pro)
- 🔄 Update through OTA low-charge (<30%)
- 🛠️ Install custom firmware (LineageOS, Pixel Experience) without unlocking the bootloader
How to restore:
- Recovery: If the phone turns on but reboots cyclically, try retracing to the previous version via Mi Recovery (select Install update.zip and point the way to the old firmware).
- Fastboot Firmware: If the phone is not booting but is detected by the PC in Fastboot mode (check through the fastboot devices command), run the official firmware: fastboot flash boot.img fastboot flash system.img fastboot reboot
- Unlock bootloader: If the phone is locked (This device is locked), you need to get permission from Xiaomi via the Mi Unlock Tool (can take up to 72 hours).
Download official firmware on MIUI Downloads. Choose a version for your model and region (Global, EEA, China).
💡
If the phone turns on after the upgrade, but the sensor or camera doesn't work, it's not a "brick" but a driver conflict. Try resetting your settings in Safe Mode.
5. Recovery through EDL (Emergency Mode)
If Xiaomi’s phone is not detected in Fastboot and does not load into Recovery, the last chance is firmware via EDL (Emergency Download Mode), which is available even on dead devices, but requires special hardware (Qualcomm HS-USB QDLoader 9008).
How to log into EDL:
- Turn off the phone (if it doesn’t respond, wait for the battery to run out).
- Press the Volume Up buttons + Volume Down and connect USB-plug-in.
- Device Manager should appear Qualcomm HS-USB QDLoader 9008.
To run through EDL, you will need:
- 🖥️ Mi Flash Tool (download from official website)
- 📁 Firmware in.tgz format for your model
- 🔌 Original. USB-cable (better to use) USB 2.0)
Firmware process:
- Unpack the firmware in a folder without Cyrillic symbols.
- Open the Mi Flash Tool, press Select and point the path to the firmware folder.
- Connect the phone in EDL mode and press Refresh – the device must be determined.
- Select Clean All (full reset) and press Flash.
⚠️ Attention: Firmware through EDL It erases all data, including Mi Account and Google accounts, and if the phone was enabled Mi Cloud Lock, after firmware you will need to enter a password from your Xiaomi account.
6.Mi Account and Activation Problems
If Xiaomi phone turns on but requires a password from Mi Account (even after reset), this means that Find Device (analogue to Find My iPhone) is activated. Without a password, you can not use the phone - it will be blocked after each reboot.
How to unlock:
- If you remember the password: Enter it on the activation screen. Once unlocked, turn off Find Device in the settings (Settings → Mi Account → Find Device).
- If you don't remember your password: Try to restore access via account.xiaomi.com (you'll need a linked email or phone number).If the recovery doesn't help, contact Xiaomi with a check to buy.
If you bought a phone with your hands:
Mi Cloud
Cost of official unlocking through the service center: 3000-8000 ₽ (It depends on the model. Informal means (via EDL Deep Flash Cable can result in total loss of warranty.
Diagnostics by external signs
If you are not sure about the cause of the malfunction, use this table for the initial diagnosis:
| Symptoms. | Probable cause | Action |
|---|---|---|
| The phone vibrates, but the screen is black. | Problem with display plume or backlight | Connect to an external monitor via USB-C → HDMI |
| The indicator flashes red, but does not charge | Failure of the power controller | Try another charge if it doesn’t help – repair |
| The phone is warming up, but it won't turn on. | Short circuit on board or in the battery | Shut down the network immediately! |
| When connected to a PC, it makes sound, but is not determined | The problem is USB-port-to-stack | Try to flash through Fastboot or EDL |
| The phone turns on but shuts off after 5-10 seconds. | Battery malfunction or processor overheating | Check the temperature of the body, try to replace the battery |
If none of the symptoms are right, try a test call:
- Call your phone from another device.
- If you hear a beep or vibration, there is a problem with the display or plume.
- If the call is reset or the phone does not vibrate, the motherboard or battery is malfunctioning.
⚠️ Warning: Unofficial services often offer “cheap” repairs using used parts, which can cause a relapse in 1-2 months.
💡
If the phone is warranty (up to 12 months from the date of purchase), repairs in the official Xiaomi service will be free, provided that the breakdown is not caused by mechanical damage or unauthorized firmware.
