The situation when your favorite smartphone suddenly stops responding to the press, can knock out any user. Xiaomi Redmi 4X, despite its legendary reliability and metal body, is not immune to software failures or hardware problems. If the screen is out and the device does not show signs of life, do not immediately panic or carry the gadget to the service center.
In most cases, the problem will be solved on its own within minutes, if you know the correct algorithm of actions. There are many reasons why the Redmi 4X may not turn on, from a banal battery discharge to a deep freeze of the system or a failure in the firmware, we will analyze all possible scenarios, from simple methods to more complex procedures for resuscitation of the device.
Itβs important to understand that the diagnosis must be done consistently so as not to make things worse. Sometimes the phone just βthinksβ itβs off when itβs actually in deep sleep or kernel error mode. By following the instructions below carefully, you can identify the nature of the malfunction and bring your Xiaomi back to life at no extra cost.
The main reasons for the lack of reaction to the power button
Before you get into action, you have to rule out the basics, and users often forget about them in a hurry. The most obvious but critical reason is that the lithium-ion battery is completely drained. If you've been out of use for a long time or left it dead, the chemical processes inside the battery could have slowed down so much that the power controller blocks the start.
The second common scenario is a software βdead endβ of the MIUI system. The smartphone could freeze during the shutdown or upgrade phase, and now it does not respond to short presses. In this case, the physical Power button ceases to perform its function because the operating system does not process the input. It is also worth checking the integrity of the charging cable and the power supply unit, since damage to the wires often simulates the breakdown of the phone itself.
β οΈ Warning: If the indicator does not light up after charging 15-20 So, take a minute to conclude that the battery is dead, and the lithium cells take time to get the minimum voltage.
The third reason is mechanical damage: Redmi 4X crashes could cause the display plume or the power button to move away. Visually, the device may look whole, but the contact inside is broken. Also, you should pay attention to the Micro-USB charging port: pile, dust or oxidation of contacts often interferes with normal energy flow.
The method of forced reset (Hard Reset buttons)
If the screen is black and the phone is not vibrating, the first thing you need to do is try to do a forced reboot, which is data-safe and helps in 80 percent of software freezes, and it emulates battery extraction by breaking the CPU power circuit in a software-based way.
To perform the procedure on the Xiaomi Redmi 4X model, you need to press the on button and hold it for a long time. The standard short press here will not work, since the system ignores interruptions. You will need patience and a firm hand.
βοΈ Hard reset algorithm
The process is as follows:
- π Connect your smartphone to the original charger.
- π Find the Power button (usually at the top right).
- β±οΈ Press and hold the button continuously for 15-20 seconds.
- π³ When you feel a vibration or see the Mi logo, release the button.
If nothing happens after 20 seconds, try a button combination. Some firmware versions help to hold the Power and Volume Up together. Hold them for about 10-15 seconds. This action can throw the device into Recovery mode or just reboot the system kernel.
Long-term charging and resuscitation of the battery
When the phone is idle for several months, the battery voltage drops below the start threshold of the controller, in which the Redmi 4X can show signs of life (blinking indicator), but does not turn on.
Leave the device connected to a powerful power supply (preferably 2A or higher) for at least 40 to 60 minutes. Do not try to turn it on at this time. Current should "swing" the battery cells. USB-The port is less efficient due to low current.
β οΈ Warning: If the phone gets too hot during storage or charging, turn it off immediately.Attempting to charge a bloated or overheated battery can cause a fire.
After an hour of charging, try to re-energize the forced-on procedure described above. Sometimes the charging indicator lights up after an hour, and the phone itself turns on after another 10 minutes. Patience is key. Also check if the charging port is contaminated. Carefully, without metal objects, clean the Micro-USB socket with a wooden toothpick or a plastic spatula.
How to check the status of the battery without turning on?
Enter Recovery and Fastboot Mode
If the buttons are reacting (there is vibration) but the screen is black or the logo is hanging, it may be that the system files are damaged. In this case, the Recovery Mode Recovery Menu will help. It is a diagnostic interface built into the phone's memory regardless of the main OS.
To get into the Recovery menu on Xiaomi Redmi 4X:
- Make sure the phone is turned off.
- Press the Volume Up and Power buttons at the same time.
- Hold them until the Mi logo appears, then let go of Power, but keep holding Volume Up.
- A menu with an orange or black background should appear on the screen.
In this menu, you can navigate with volume buttons and you can choose with power buttons. You're interested in Wipe Data or Reboot. Selecting Wipe Data will completely delete all your photos, contacts and apps, returning your phone to factory settings. Use this only if the data is not important or the backup is saved.
There's also a Fastboot mode that's used for flashing, and you can enter by squeezing Volume Down and Power, and if you see a picture of a rabbit fixing an android on the screen, the hardware (screen, processor, memory) is probably working, and the problem is the software.
Diagnostics of hardware faults
When software is powerless, you have to look at hardware issues, and the Redmi 4X has a number of typical diseases, and one of them is the plume dump of the display, and if the phone vibrates and makes sounds when you call, but the screen is black, the plume contact may have gone.
Another common problem is the failure of the power controller or the power button itself, and the button can physically fail or oxidize, and you can check this by gently (without fanaticism) pressing the button area or tapping your finger on the back cover in the upper right corner.
| Symptoms. | Probable cause | Action. |
|---|---|---|
| The indicator flashes red. | Critical battery discharge | Long-term charging (1+ hour) |
| Vibration's on, no screen. | Software failure or display plume | Recovery / Checking the plume |
| The top is warming. | CZ in the power supply chain or processor | Get in service, no charge! |
| Fastboot mode (hare) | Accidental hitting on the regime | Hold the Power 15 seconds |
If the phone heats up in the area of the camera or processor immediately after connecting to charging, this is a sign of a short circuit on the board, in which case further attempts to turn on the device can finish off.

Try connecting your phone to your computer. If the PC makes a sound of connecting a new one. USB-The device, therefore, the power controller is alive, and the phone can be tried to βreviveβ flashing through the Mi Flash program.
