How to turn on the smartphone Xiaomi Poco M3: 5 working methods

Xiaomi Poco M3 is a popular budget smartphone with a powerful 6,000mAh battery, but even it sometimes refuses to turn on. The reasons can be different from a dead battery to software failures. In this article, we will discuss all possible ways to launch the Poco M3, including forced reboot, charging in a switched-off state and recovery via Fastboot.

If your device doesn't respond to the power button, don't rush to bring it to the service. In 80% of cases, you can solve the problem yourself in 5-10 minutes. We have collected proven methods - from the simplest to advanced, with explanations for beginners and technical nuances for experienced users.

1. Standard on: Power button

Let's start with the basic method, which works 95% of the time. To turn on the Xiaomi Poco M3, do the following:

• 🔋 Connect the charger (preferably original to the 18W or 22.5W) And wait 5-10 minutes. Even if the light doesn't burn, the battery could run to zero.
• 🔘 Press the power button (located on the right side of the smartphone) for 3-5 seconds until the logo appears. POCO.
• 🕒 Wait 1-2 minutes – the system can load for a long time after a deep discharge.

If the screen is black after this, move on to the next method. Importantly, do not press the power button more than 1 time every 10 seconds, this may block the power controller.

2. Forced reset (Hard Reset)

If the smartphone is stuck on the logo or doesn't respond to the power button, a forced reboot will help, a method that doesn't delete data, but resets temporary system processes.

1. Make sure that the Poco M3 is not connected to the charger.
2. Press and hold the power button + volume button (top key on the left side) for 10-15 seconds.
3. Release the buttons when the POCO logo or vibration appears on the screen.

After a forced reboot, the smartphone can boot longer than usual (up to 3-5 minutes). If the method does not work, try repeating it with the charger connected.

⚠️ Warning: Do not confuse forced reboot with factory reset (Wipe Data): the first method is data-safe, the second one deletes everything from internal memory.

Charging in the off state: what to do if the indicator does not burn

One of the common causes of the dead Poco M3 is a deep battery drain, in which case standard charging might not help, because the power controller is blocking the current.

• ⚡ Use the original cable and power supply (or certified with Quick Charge 3.0 support).
• ⏳ Leave your smartphone on charge for at least 30 to 60 minutes, even if the indicator is not on.
• 🔄 Try another cable or socket - the problem may be the power supply.
• 🔋 If after an hour the charging indicator did not light up, try to connect the smartphone to the computer through USB — Sometimes it works.

After a long charge, try to turn the device on in the standard way (press the power button for 5-10 seconds).If the charging indicator does not appear, the problem may be a faulty battery or power controller.

4. Fastboot Recovery (for power users)

If the smartphone responds to buttons but does not load beyond the logo, Fastboot mode will help.This method requires a connection to the computer and installed Xiaomi drivers.

Instructions:

1. Turn off the Poco M3 (if it is on, press the Power + Volume Up for 10 seconds).
2. Press Power + Volume Down before the screen with the hare in the header (Fastboot logo) appears.
3. Connect your smartphone to your PC through USB-cable.
4. Download and install the Mi Flash Tool (the official utility from Xiaomi).
5. In the program, select Flash → specify the path to the firmware for Poco M3 (you can download on the official website).
6. Press Refresh, then Flash and wait for the process to complete (10-15 minutes).

This method reinstalls the firmware, but saves user data (if you choose the option Save user data).If the problem was a software failure, after firmware, the smartphone will turn on.

⚠️ Note: Firmware via Fastboot can lead to a bootloader lock if you use unofficial software.Always download firmware from the official Xiaomi website.

5.Reset via Recovery Mode (last chance)

If none of the methods worked, you have to reset hard through the recovery mode, which removes all the data from the internal memory, so use it only as a last resort.

How to reset:

1. Turn off your smartphone (forced if necessary).
2. Press the Power + Volume Up before the POCO logo appears, then release it.
3. In the Recovery menu, select Wipe Data (use volume buttons for navigation, power button for confirmation).
4. Confirm the action by selecting Yes.
5. After reset, select Reboot → Reboot to System.

After a hard reset, the smartphone will turn on as a new one, you will need to reconfigure it, including logging into your Mi Account, and if this method doesn’t work, the problem is likely to be in the hardware (motherboard, battery, plumes).
