Xiaomi Redmi smartphone does not turn on: full instructions for diagnosis and repair

You pressed the power button Xiaomi Redmi, but the screen is black, the indicators are not burning, and the device does not respond? This problem is familiar to many owners of smartphones brand — from budget Redmi 9A to the flagship Redmi K60 Pro. 80% of the time, the malfunction can be fixed without resorting to the service center, but it is important to correctly diagnose the cause: it can be as dead battery and serious failure of the motherboard.

In this article, we will look at all possible scenarios why Xiaomi Redmi does not turn on, from software failures to physical damage, how to distinguish between false death of a device from real failure, what manipulations can be done at home and when to immediately contact the service, and we have collected current data on models from 2020-2026, including features of the Redmi Note 12, Redmi 10 and other popular lines.

We warn you right away: if the phone falls into the water, has been hit hard or overheated, the chances of self-repair are minimal. In such cases, it is better not to take the gadget to the specialists. For everyone else, we start diagnosing!

1. Checking the underlying causes: battery, charging, button

Start with the basic. Most often, Xiaomi Redmi doesn't turn on because of trivial issues that are fixed in 5 minutes.

Pay particular attention to the charger. Many users use cheap cables or power supplies from other brands that don't provide enough current. For example, the Redmi Note 11 Pro with support for fast charging 67W will only work with the original adapter or certified counterpart. If the charging indicator does not light up, try:

• 🔌 Connect the phone to another power source (outlet, power bank, car adapter).
• 🔋 Leave the device on charge for at least 1 hour – sometimes the battery is discharged to such a level that even the indicator does not work.
• 🔄 Try charging from another Xiaomi smartphone (for example, from a smartphone) POCO X3 Mi 11).

If you're still not showing any signs of life after this manipulation, then you can move on to the next step, but before you do that, check the power button, and it sometimes sticks because of dust or moisture, and then you can press it carefully several times, and if you hear clicks or resistance, it's possible that the contacts have oxidized.

💡

On Redmi 9/9A/9C models, the power button often fails due to design features, and if it fails or fails to lock, the micro-switch will likely need to be replaced.

2. Forced reset and Recovery mode

If your smartphone doesn't respond to the power button, but you're sure the battery is charged, try a forced rebuke, which resets temporary OS errors and often helps when you're stuck on a black screen.

• 📱 For the Redmi Note 8/9/10/11, Redmi 9/10/12: Hold the power button. + Loudness up 10–15 A few seconds before the Mi logo appears.
• 📱 For Redmi. K40/K50, POCO F3/F4: Press the power button. + Loudness down on 20 seconds.
• 📱 For older models (Redmi) 6/7/8A): power button combination + Loudness up + Loudness down.

If the phone is turned on after a forced reboot, but it is unstable (spontaneously shuts down, brakes), this is a sign of a software failure, in which case the reset via Recovery Mode will help:

1. Turn off the phone (if it is turned on after the reboot).
2. Hold the Power button + Volume up until the Recovery menu appears.
3. Select Wipe Data (Data Reset) or Reboot (Reboot).

⚠️ Warning: Wipe Data reset will delete all user data (photos, contacts, apps).If your phone had important files, try connecting it to your PC in Fastboot mode first. + Loudness down) and copy the data.

3. Diagnosis of hardware breakdowns: what can be checked at home

If the software methods didn't work, the problem is probably hardware.

The most common hardware problem is a faulty battery, the average battery life in Xiaomi Redmi is 2-3 years, after which it loses capacity and may not hold a charge.

1. Enter the dialer code: ##4636##.
2. Go to the Battery Information section.
3. If you look at the Health parameter, if it's below 80 percent, you should change the battery.

⚠️ Warning: If the phone is hotter than 50°C when you connect to a charge, immediately turn it off! This is a sign of a short circuit that could cause a fire.

4. Firmware recovery via Fastboot and EDL

If the phone turns on but only boots to the Mi logo or reboots cyclically, it's the firmware that's to blame, and it can happen after a failed update, custom software installation, or system failure, and in such cases, flashing through Fastboot or EDL modes will help.

First, try Fastboot:

1. Download the official firmware for your model from the Xiaomi Firmware website (choose the Fastboot version).
2. Unpack the archive in a folder on your PC.
3. Hold the Power button + Volume down on your phone to log into the Fastboot.
4. Connect your phone to your PC and launch the file flash_all.bat (for Windows or flash_all.sh (for macOS/Linux).

If Fastboot doesn't work, you'll have to use EDL, which allows you to flash your phone even if you're seriously damaged by the bootloader, but requires an EDL cable or a short circuit of the contacts on the board. Be careful: wrong actions in the EDL can finally kill the device.

For firmware via EDL:

1. Download the Mi Flash Tool from Xiaomi’s official website.
2. Install Qualcomm drivers (for Snapdragon processors) or MediaTek (for Helio/Dimensity chips).
3. Connect your phone in EDL mode (the instructions for your model may be different!).
4. In the Mi Flash Tool, select the firmware and press Flash.

💡

Firmware through EDL is a last resort, and if you're not sure what you're doing, you better go to the service, and if you're not firmware right, you can lose your IMEI or lock the bootloader.

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

Not all malfunctions can be fixed at home, but here's the reading for a visit to the service center:

• 🔥 The phone is warmed for no apparent reason (even when it is off).
• 💧 Contact with water or other liquids (even if a few days have passed).
• 🔌 After a fall or impact, the phone stopped turning on.
• 📵 Artifacts appear on the screen (stripes, flickering, broken pixels).
• 🔋 The battery swelled (seems to be on the raised back cover).

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

⚠️ Note: if your Xiaomi Redmi is warranty, do not attempt to repair it yourself! opening the case or unofficial firmware will void warranty obligations.

Before visiting the service, do the following:

1. Check if they have original parts for your model (especially for newer smartphones like the Redmi Note 13 Pro+).
2. Ask about the possibility of a diagnosis before repair – some services even charge for an inspection.
3. If the phone is turned on but glitchy, back up your data via Mi Cloud or ADB.

6.Prevention: How to avoid inclusion problems

To ensure that your Xiaomi Redmi lasts longer and doesn’t “die” at the most inopportune moment, follow these guidelines:

• 🔋 Use only original or certified chargers. Cheap adapters can damage the power controller.
• 🌡️ Avoid overheating: Do not leave your phone in direct sunlight or on charge during games.
• 💧 If the phone is wet, turn it off immediately, remove it. SIM-card and battery (if possible), then dry in rice or silica gel for at least 24 hours.
• 📲 Regularly update the firmware through Settings → The phone. → Updating the system.
• 🔄 Once every 3-6 months, reset your cache via Recovery (does not delete user data).

Pay special attention to the battery. Modern lithium polymer batteries don't like:

• Deep discharge (below 5%).
• Extended 100% charge (especially in the heat)
• Use of cheap powerbanks with poor-quality voltage stabilization.

Optimal charging range for prolonging battery life is 20%–80%. If your Redmi starts discharging too quickly (e.g., loses 50% in 2–3 hours), it’s a sign of battery degradation — consider replacing it.

💡

On models that support wireless charging (Redmi K50 Ultra, Redmi Note 12 Pro+), avoid using uncertified stations.
