How to turn on Xiaomi Mi 6: all ways to launch a smartphone after a crash or discharge

Why Xiaomi Mi 6 doesn’t turn on: the main reasons

The Xiaomi Mi 6, launched in 2017, is still popular with users thanks to its powerful Snapdragon 835 processor and robust design, but even such devices can face power problems, most often due to:

• Full discharge of the battery (especially after long-term storage without recharging).

• Software failures after updating MIUI or incorrect shutdown.

• Hardware malfunctions (damaged power supply plume, oxidized battery contacts).

• Hanging on the Mi logo due to application conflict or damaged firmware.

In 80 percent of cases, you can fix the problem without going to the service center, and below we'll discuss 5 working ways to turn on the Mi 6, from the elementary to the advanced, using a computer.

Method 1: Forced button reboot

If the Mi 6 screen is black and does not respond to the charging connection, try the hard reset first, which will work even if the smartphone is getting stuck on the screensaver or does not show signs of life.

Instructions:

• 🔘 Press the power button and the volume button at the same time.
• 🕒 Hold them for 10-15 seconds until you feel a vibration or the Mi logo appears.
• ⚡ If the screen blinks and goes out, release the buttons and wait 30 seconds. Then try turning on the smartphone in the usual way.

If the Mi 6 is turned on and off immediately, the problem is with the battery being discharged, plug in the original charger and wait 15-20 minutes before re-energizing.

Make sure the charger is offline |

Check if the power button is stuck |

Try to connect another charger |

Hold the buttons for at least 15 seconds.

⚠️ Warning: Don't confuse hard reset with Fastboot login! If an Android robot with the word No command appears after holding the buttons, then you're in recovery mode.

Method 2: Charging in the off state

The Xiaomi Mi 6 battery (capacity 3350 mAh) is sensitive to deep discharge. If the smartphone does not turn on after a long downtime, its battery could go into “sleep mode” – a state in which the power controller blocks charging.

To wake up the battery:

1. Connect the Mi 6 to the original charger (at least 18 watts).
2. Leave your smartphone to charge for at least 30 minutes, even if the indicator is not on.
3. After 30 minutes, press and hold the power button for 20-25 seconds.
4. If the charging icon appears, wait another 10-15 minutes and try to turn it on.

If the charging indicator never caught fire, try:

• 🔌 Use a different cable and power supply (preferably from Xiaomi).
• 🔋 Connect your smartphone to your computer through USB — Sometimes it works when charging from the socket does not help.
• 🔄 Change the polarity of the cable (turn the USB-Type C connector) if you use a non-original wire.

Method 3: Enable via Fastboot mode

If the Mi 6 is responding to charging (the indicator is on), but not turning on in the usual way, the boot sector may be damaged, in which case entering Fastboot mode and forced reboot will help.

Step-by-step:

1. Turn off the smartphone (if it freezes – perform a hard reset from Method 1).
2. Press the power button + volume down button at the same time.
3. Hold on until a screen with an Android image and a Fastboot label appears.
4. Connect the Mi 6 to your computer via USB-cable.
5. On PC, open the command line (Win + R → enter cmd) and execute the command: fastboot reboot

If after this command the smartphone successfully restarted, the problem was a temporary failure of the bootloader. If not, you will need to flash it.

💡

Before working with Fastboot, install the Mi Flash Tool drivers and disable the driver signature in Windows. Otherwise, the computer will not recognize the device.

Method 4: Flashing through the Mi Flash Tool (for experienced)

This method should only be used if the previous methods did not help and you are confident in your skills.

To flash Xiaomi Mi 6 via PC you will need:

• 💻 Windows computer 7/10/11.
• 🔌 Original. USB-cable (better from the set).
• 📥 Fastboot firmware ROM For Mi 6 (Sagit version) downloaded from Xiaomi official website.
• 🛠 Mi Flash Tool (last version).

Instructions:

1. Unpack the downloaded firmware in a folder without Cyrillic characters (for example, C:\Mi6_Firmware).
2. Install the Mi Flash Tool and drivers for Xiaomi.
3. Turn off the Mi 6 and turn it into Fastboot mode (power button + volume reduction).
4. Connect your smartphone to your PC and start the Mi Flash Tool.
5. In the program, click Select, specify the path to the firmware folder, then select Clean all (full cleaning) or Clean all and lock (with bootloader lock).
6. Press Flash and wait for the process to end (5-10 minutes).

⚠️ Note: Firmware through Clean all and lock will block the bootloader, which can complicate further manipulation of the software. Use this mode only if you are sure that you will not install custom firmware.

💡

Flashing through the Mi Flash Tool is the most reliable way to bring the Mi 6 back to life in case of software failures, but requires strict adherence to instructions.

Method 5: Diagnostics of hardware malfunctions

If none of the software methods worked, the problem is probably hardware. Here are the typical hardware malfunctions of the Xiaomi Mi 6 and their signs:

• 🔋 Faulty battery: the phone only turns on from charging, but immediately turns off when disconnected. ~1500–2500 ₽).
• 🔌 Damaged charging connector: charging only in a certain position of the cable. The solution is to replace the connector (USB-Type C).
• 📱 Oxidation of contacts on the motherboard: the phone periodically turns off, warms up.
• 🔧 Power controller malfunction: no response to charging and buttons. Solution - repair or replacement of board.

For self-diagnosis:

1. Take apart the smartphone (you need a plastic blade and a screwdriver T3).
2. Check if the battery is swelling (if so, don’t turn on the device! it’s dangerous).
3. Examine plumes and contacts for oxidation or breaks.
4. Try connecting another (knowingly working) battery from the Mi 6.

If you are not sure about your skills, you should contact the service. The average cost of diagnostics Xiaomi Mi 6 in Russia is 500-1000 ₽.

Frequent Mistakes and How to Avoid Them

Many users make the problem worse by doing the wrong thing, and here's what you can't do if the Mi 6 doesn't turn on:

• 🔥 Connecting non-original chargers with voltages above 5V – this can burn the power controller.
• 💥 Disassemble the smartphone without turning off the battery - the risk of short circuit.
• 🔄 Interrupt the firmware process - this will lead to the "bricking" of the device.
• 🌡 Heating or cooling your smartphone (such as putting it in the freezer) can temporarily help, but hurt the charge in the long run.

Also not worth it:

• 🔋 Use "curved" firmware from dubious sites - they may contain viruses.
• 🔧 Self-soldier board elements without experience - the Mi 6 has a multi-layer board that is easy to damage.
• 📱 Pressing the screen with force - this can tear off the display plume.

💡

If the Mi 6 stopped turning on after the fall, don't shake it or knock on the body.Mechanical damage often leads to microcracks on the board, which oxidize over time.
