Modern Poco smartphones from Xiaomi are famous for their performance and optimized interface MIUI or HyperOS. However, even the most advanced devices sometimes face a situation where the screen remains black and the device does not respond to the usual actions of the user. Owners often panic, believing that the gadget is out of order, although in most cases the problem is solved by simple manipulation of power or software.
In this article, we will take a look at all possible scenarios for starting a device, from standard procedure to complex cases where you need to enter recovery modes, how to distinguish a software failure from a hardware malfunction, and what steps you need to take if your smartphone stops turning on after discharging or updating. Understanding these processes will help you save time and avoid unnecessary visits to the service center.
Importantly, the algorithms of actions can vary slightly depending on the model, whether it is the flagship Poco F5 or the budget Poco C55. We will look at the universal methods applicable to most current models, as well as the specific nuances specific to Chinese and global versions of firmware.
Standard first-on and-start procedure
When you first start a new smartphone or after you completely drain the battery, the device requires a special approach. If you have just unpacked the box, you should not expect an instant reaction of the screen on a short press. The battery could run to zero during long-term storage in stock, so it takes time to accumulate a minimum charge before starting the system.
Connect the original charger and cable to the network and phone. Leave the gadget alone for at least 15 to 20 minutes. Even if the charging indicator or Xiaomi logo does not light up on the screen, the energy storage process is already underway. Modern power controllers block the on-set at critically low voltage levels to protect the battery's chemical elements from degradation.
After a pause, try a classic action: press the power button and hold it. Depending on the model, it can take 3 to 10 seconds. On some devices, such as the Poco X4 GT or Poco F4, it takes longer to activate than on older models. If the screen catches fire and the brand logo appears, release the button and wait for the operating system to boot.
☑️ The initial launch of the smartphone
Sometimes users confuse the off state with deep sleep mode. If the phone does not respond to a short press, try unlocking it with a combination of buttons or check if the "Do Not Disturb" mode is activated with the screen completely turned off. In rare cases, it helps to connect to a computer through USB-cable that can wake up the device controllers.
What to do if the smartphone does not turn on and the black screen
A situation where the phone completely ignores the button presses and shows no signs of life is called "Black Screen of Death." This does not always mean that the display or motherboard breaks. Often the reason lies in the Android process freezes, which can not complete the background services, in which case a forced reboot is required, which simulates the extraction of the battery.
To perform a hard reset on most Poco models, you need to press two buttons simultaneously: power and Volume Up. Hold this combination for 10-15 seconds. The screen may go out and light up again, or you will feel a slight vibration. This is a signal that the system has received a command to restart.
⚠️ Warning: Do not release buttons immediately after the logo appears. Keep them clamped until the device begins to vibrate or until the language selection menu or Fastboot logo appears on the screen.
If the volume button combination doesn’t work, try holding the power button for 20 to 30 seconds. On some global firmware versions, this method is the main one for resetting static electricity and restarting the controller. It’s also worth checking the integrity of the charging cable and the power supply, since the lack of reaction can be a banal lack of power.
Why does the phone warm up but not turn on?
In cases where nothing helps, you should pay attention to the notification indicator. If it flashes red or orange when connecting to a charge, this indicates a deep discharge or charging error. Try replacing the cable or power supply with a known serviceable one to eliminate problems with accessories.
Enter Recovery and Fastboot on Poco
Recovery and fastboot modes are essential for resetting, flashing, or diagnosing hardware errors, and are entered when the phone is off using special keyboard combinations, critical tools for any Xiaomi owner.
To enter the Recovery menu, do the following: turn off the device completely (if it is on), then simultaneously press the power and volume buttons. Hold them until the Mi logo appears, then release the power button, continuing to keep the volume. In a few seconds, the main recovery menu will open.
Navigation in this menu is done with volume buttons (up/down), and the choice of item is confirmed by the power button. Here you can choose a language (usually English), perform a data reset (Wipe Data) or restart the system (Reboot). Be careful: resetting data will delete all information from internal memory.
Fastboot mode is called in a similar way, but using Volume Down. Press the power and volume down at the same time. The screen will show an image of a hare repairing an android, or the words FASTBOOT. This mode is used to low-level firmware of the device through the computer.
Table of key combinations for different models
While the logic of buttons is the same across the ecosystem, there are nuances depending on the series of devices, and here is a summary table that will help you quickly navigate your Poco model.
| Model of the device | Inclusion (standard) | Recovery Mode | Fastboot Mode |
|---|---|---|---|
| Poco F3 / F4 / F5 | Power (5 sec) | Power + Vol Up | Power + Vol Down |
| Poco X3 NFC / Pro | Power (5 sec) | Power + Vol Up | Power + Vol Down |
| Poco M3 / M4 / M5 | Power (5 sec) | Power + Vol Up | Power + Vol Down |
| Poco C40 / C50 | Power (7 sec) | Power + Vol Up | Power + Vol Down |
| Poco X4 GT / F4 GT | Power (10 sec) | Power + Vol Up | Power + Vol Down |
Note that on side-fingerprint scanner models (like the Poco X3 Pro), the scanner button and the power button are the same. Press it clearly and confidently. Some budget C-series models may require longer key retention due to firmware features.
If the combinations don't work, make sure the phone is completely off before starting the procedure.Any attempt to log in to Recovery on a device turned on will only lock the screen or call Google's voice assistant, but won't open the desired menu.
Solving problems with hanging on the MIUI logo
One of the most common problems is bootloop, which is an endless reboot or hanging on the brand logo, which can happen after a failed system update, memory overflow, or the installation of damaged applications, in which case standard activation is impossible, you need to interfere with the boot process.
The first step is to try Safe Mode if the system is at least partially responsive. However, if you freeze completely, the best way to reset is to reset via Recovery. Go to the recovery menu (as described above), select English, then go to Wipe Data → Wipe All Data. Confirm the action by selecting Confirm.
⚠️ Note: Wipe All Data will completely destroy all your photos, contacts and applications. If you do not have a backup in the Mi Cloud or Google Photos cloud, data will not be restored.
After the cleaning process is complete (Progress: 100%), select Reboot → Reboot to System. The first run after the reset will take longer than usual - from 3 to 10 minutes. Don't panic if the phone is hanging on the logo at this time, the initial file table settings are going on.
💡
If the phone is stuck on the logo after reset, the system partition may be damaged or the battery does not hold the voltage under load. Try replacing the battery or reflashing the device through the computer using the Mi Flash Tool utility.
In some cases, the problem lies in the incompatibility of installed updates. If the reset did not help, you will need a complete flashing of the device ("clean" firmware), which is a more complex procedure, requiring a PC and an unlocked bootloader (in some regions).
Diagnostics of hardware faults
If neither software nor resetting has helped turn on the smartphone, there is a high probability of hardware failure, such as failure of the display plume, damage to the power controller or bloating of the battery. A bloated battery is not only the cause of failure, but also a fire element.
Carefully examine the body of the device. If the back cover has moved away, the screen has pressure stains or the phone is lying on the table and scrolls spontaneously with a light touch - the battery is swollen, in which case it is strictly forbidden to try to charge the device or turn it on, as this can lead to ignition.
Another sign of hardware failure is the charging response (vibration, sound), but the lack of image even when the screen is illuminated with a flashlight, which indicates a malfunction of the display matrix or the plume. It is also worth checking the charging connector: if the cable is hanging or charging only in a certain position, the problem may be in the USB Type-C socket.
💡
If the phone does not turn on after falling or getting moisture, self-attempts to turn on can aggravate the corrosion of contacts.
For a final diagnosis at home, you can try to gently (without fanaticism) press the camera area or the bottom of the back cover when turned on, sometimes helping to restore contact of the plume if it is slightly removed, but this is only a temporary solution that requires professional repair.
