Xiaomi Redmi phone does not turn on: what to do if the screen is black and there is no reaction to charging

Your Xiaomi Redmi is no longer on, the screen is black, and the charging indicator is not on? This problem is familiar to many owners of smartphones of the brand – from the budget Redmi 9A to the flagship Redmi K60 Pro. The reasons can range from a banal battery discharge to serious hardware breakdowns. 70% of the time the device manages to “reanimate” yourself without the help of a service center.

In this article, we will look at all possible scenarios for why Redmi doesn’t turn on, from software failures to physical damage, how to distinguish a soft bug from the death of the motherboard, what button manipulations can bring the phone back to life, and when to accept the need for repairs, and focus on the methods of recovery without loss of data and the typical errors that users make when trying to resuscitate.

If the phone falls into the water, gets hit hard or gets overheated, the chances of repairing yourself are minimal, and otherwise, follow our instructions in order, from simple to complex.

1. Checking for obvious reasons: charging, cables, buttons

Start with basic diagnostics, and often the problem is little things that users overlook.

• 🔌 Change the charger and cable. Use Xiaomi's original power supply (or Quick Charge-enabled certified equivalent). Cheap cables often don't provide enough current to run a dead battery.
• 🔋 Try another socket. Connect the charger to another socket. USB-The computer port or outlet, sometimes the problem is the faulty wiring.
• 📱 Clean the charging connector. Use a toothpick or compressed air to remove dust and debris. On the Redmi Note models. 10/11 frequent cause of lack of reaction - oxidation of connector contacts after moisture enters.
• 🔘 Press the power button for 20-30 seconds. Sometimes the phone freezes in deep sleep, and prolonged holding the button resets the state.

If you have a charging indicator after this manipulation (even a flashing one), it means that the problem was the power supply. Let the phone charge for at least 15-20 minutes, then try to turn it on in the standard way. If there is no indicator, move on to the next step.

⚠️ Note: Do not use “fast charging” from other brands (such as Samsung or OnePlus). Xiaomi’s power controllers are set up to specific protocols, and incompatible units can cause battery failure.

2. Forced reboot: Hard Reset and button combinations

If the phone doesn’t respond to charging, but you’re sure the battery isn’t running out (like the device turned off while in use), try forced reboot, which works even when the firmware freezes or Android kernel conflicts.

The button combinations depend on the Redmi model:

After a forced reboot, the phone should show the Xiaomi logo or the Fastboot menu. If the screen is black, but the device vibrates, this is a sign of damage to the display or plume. If there is no reaction at all, move to the next section.

Diagnosis of the battery: how to check without disassembly

A battery that is dead or out of order is one of the most common reasons why Redmi doesn't turn on. If your phone doesn't respond to charging and forced reboot, follow these steps:

• 🔋 Check the heating. Connect the phone to charge and hold for 5-10 minutes. If the case heats up in the battery area (usually the bottom), this may indicate a short circuit inside the battery.
• 🔌 Use it. USB-If the phone was previously connected to the PC in debugging mode (ADB), try the command: adb devices If the device is defined in the list, but not included - the problem is in the firmware or bootloader.
• 🔧 Check with a multimeter (for advanced users). Xiaomi battery usually has 3 contacts: +, – and BMS. Measure the voltage between + Normal value - 3.7-4.2 V. If less than 3.0 V, the battery is deeply discharged and may not take charge.

If the battery is swollen (you can see it from the rear cover or the screen glass), do not try to charge it - it is dangerous!

⚠️ Note: On Redmi models with a non-removable battery (for example, Redmi Note 11 Pro), self-replacement without experience can damage the plume of the display or antenna modules.

4.Recovery via Fastboot and Mi Flash Tool

If the phone reacts to button combinations and goes into Fastboot mode (a black screen with the Mi Bunny logo and the Fastboot label), but does not boot further, the problem lies in the firmware, in which case the firmware will help to flash through the official Mi Flash Tool utility.

Step-by-step:

1. Download the firmware for your model from the Xiaomi Firmware website. Choose the version of Fastboot (file with the extension.tgz).
2. Download Mi Phone Manager or Xiaomi driver package for Fastboot.
3. Connect your phone to your PC in Fastboot mode (hold Power + Volume down when connecting the cable).
4. Run the Mi Flash Tool, select the downloaded firmware and press Flash. In the utility settings, select Clean All (complete clean) or Save User Data (save data).

It takes 5-10 minutes. When you're done, the phone automatically restarts. If you have an Anti Rollback error after you've run the firmware, you're trying to install an older version of MIUI than you did before, and you're going to download a newer firmware.

5. Hardware damage check: What can be done at home

If none of the software methods worked, it's time to look at the hardware malfunctions, some of which can be diagnosed by yourself:

• 📱 Damage to the display or plume. Hold the phone to a bright light – if the black screen barely shows an image (for example, the Xiaomi logo when booting), the problem is in the backlight or plume.
• 🔌 Power controller malfunction: If the phone is unresponsive to charging, but when connected to a PC is defined as Qualcomm HS-USB QDLoader 9008, this is a sign of a power supply failure (often after a drop or moisture hits).
• 🔋 If the phone is heated but not turned on, it can collapse memory chips or processor (typical for Redmi Note). 8/9 post-impact).

For more accurate diagnosis, you can use the test mode (if the phone somehow responds to the buttons):

1. Keep Power + Volume up until the Recovery menu appears.
2. Select Connect with MIAssistant (on some models – Advanced → Test Device).
3. Connect your phone to your PC and run the Mi PC Suite, and the Diagnostics section will show hardware component errors.

⚠️ Note: If an error is displayed in the test mode EMMC error UFS Error, that means memory damage, and self-repair is impossible, so you need to replace the chip at the soldering station.

💡

If the phone falls into water, don't turn it on right away! Place the device in a silica gel (or rice) bag for 24 to 48 hours. Attempting to turn it on before drying out completely can cause a short circuit.

6.When to contact the service: signs of serious breakdowns

Not all malfunctions can be fixed at home. Please contact Xiaomi Service Center if:

• 🔥 The phone overheats even without charging (a sign of a short circuit on the board).
• 💧 On the screen or under the glass, traces of corrosion are visible (liquid getting into the screen).
• 🔌 When connected to a PC, it is defined as Unknown Device or QHUSB_BULK (controller failure USB).
• 📱 The phone vibrates, but the screen remains black (damage to the plume or matrix).
• 🔋 The battery swelled or deformed the body.

The cost of repairs in official Xiaomi services (in Russia for 2026):

Before visiting the service, back up your data if the phone is at least somehow responsive to the connection to the PC. In most cases, during hardware repairs, the device's memory is formatted.

💡

If the phone is warranty, don't open it yourself! disassembly of the case will void Xiaomi's warranty obligations.

7 Prevention: How to avoid problems in the future

To make your Redmi last longer without crashing, follow these guidelines:

• 🔋 Don't drain the battery to 0%. Optimal charge range is 20-80%. Complete discharge accelerates battery degradation.
• 🔌 Use the original chargers. Cheap power supplies can cause power surges that damage the charging controller.
• 📱 Update the firmware. Regular updates. MIUI Correct errors in the management of power and the core of the system.
• 💧 Avoid overheating and moisture. Do not leave your phone in direct sunlight or near heat sources (e.g., on a car torpedo).
• 🔄 Reset every 6 to 12 months, which clears the system partition of debris that can cause freezes.

It is also useful to disable unnecessary background processes that consume charge and load the processor. To do this, go to Settings → Battery → Power Saving Mode and select Balanced or Long Life profile.
