Mi Band 3 doesn’t turn on after charging: 5 working ways to start

Did you take the Xiaomi Mi Band 3 out of the box, plug it into the charger, but the screen is black? Or did the bracelet suddenly run out and now it shows no signs of life? This problem is familiar to many owners of smart gadgets — especially if the device has been idle for a long time. 80% of the time it is not a failure, but the peculiarities of the firmware or battery.

Unlike the current Mi Band 7 or Mi Smart Band 8, the third version of the bracelet has more modest hardware resources and sometimes falls asleep after a deep discharge. But don’t rush to carry it to the service center: in 95% of cases, the device can be brought back to life on its own without a soldering iron or special skills. In this article, we will analyze all possible reasons why the Mi Band 3 does not turn on after charging, and give step-by-step instructions for restoring performance.

Why Mi Band 3 does not turn on after charging: top-5 reasons

Before you start resuscitation, it’s important to understand what exactly caused the problem.The Xiaomi Mi Band 3 has a few typical “diseases” related to nutrition:

• 🔋 Deep battery discharge – if the bracelet has been discharged for more than 2-3 weeks, the power controller may block charging.
• 🔌 Faulty cable or adapter – even the original chargers wear out over time (especially the contacts).
• 📱 Firmware failure – after updating or resetting the bracelet may “hang” during the boot phase.
• 💧 Moisture intrusion – Despite the stated IP68, charging contacts oxidize over time.
• 🔄 Hanging after synchronization – if the bracelet is “glued” during data transfer to the Mi Fit application.

The most common situation is that the bracelet does not respond to charging due to a deep discharge, but the indicator (red light) does not burn, which means that the power controller blocked the current supply to the battery, in which case standard charging will not help, you need to use alternative methods.

Method 1: Proper charging – check cable and contacts

Start with the basic diagnostics. Even if you think the charger is working, 60 percent of the problems with turning on the Mi Band 3 are power-related.

Examine the cable for damage (curves, insulation breaks)

Wipe the contacts of the bracelet and charging with an alcohol napkin

Try another USB-port or power adapter (5V/1A)

Keep the bracelet on charge for at least 30 minutes (even if the indicator is not on)-->

Pay special attention to the contacts on the back of the bracelet, which over time become oxidized or coated with plaque, which prevents normal charging.

• 🧴 Alcohol wipes - wipe the contacts gently without pressing.
• 🪒 Cotton brushing for hard-to-reach areas (do not use metal objects!).
• 🔥 Hair dryer – If the contacts have moisture, dry them with warm air (not hot!).

⚠️ Warning: Never use abrasive materials (steelpaper, needles) to clean, which will damage the protective coating of the contacts and impair conductivity.

If the charging indicator never caught fire after cleaning, try an alternative power source:

If the bracelet doesn’t respond anyway, move on to the next method – most likely, the problem is deeper than it seems.

Method 2: Hard Reset for Mi Band 3

If the Xiaomi Mi Band 3 doesn’t turn on even after a long charge, but the indicator vibrates or flashes, there is likely a software failure, in which case hard reset helps, this method works even if the screen does not respond to touch.

Resetting instructions:

1. Connect the bracelet to charge and wait 10-15 minutes (even if the indicator is not on).
2. Unplug the bracelet from charging.
3. Press and hold the touch button (under the screen) for 20-30 seconds.
4. If the bracelet vibrates, release the button and reconnect to charging.
5. Wait 5-10 minutes and the Xiaomi logo will appear.

⚠️ Warning: If the bracelet switches on after resetting but switches off immediately, it's a sign of a faulty battery, and you'll need to replace the battery.

If Hard Reset doesn’t work, try the button combination:

• 🔄 Connect the bracelet to charging.
• 🖐️ Press the touch button and tap the screen easily (sometimes this helps wake up the display).
• ⏱️ Hold the button for 30 to 40 seconds until you feel the vibration.

💡

If the bracelet vibrates but the screen is still black, try holding it to a bright light source (like a lamp), and sometimes the backlight works, but it's not visible in normal light.

Method 3: “Resuscitation” after deep discharge (the “push” method)

If the Mi Band 3 is zero and has been uncharged for more than 3-4 weeks, standard methods may not work, and in such cases, the “push” method, a short-term supply of high voltage to “wake up” the power controller, helps.

You'll need:

• 🔌 Charger with output 5V/2A (from smartphone).
• 🔋 External Power Bank with capacity ≥ 10,000 mAh.
• ⏱️ Timer (you can use a smartphone).

Step-by-step:

1. Connect the bracelet to Power Bank (not to your computer!)
2. Hold on charging for exactly 5 minutes (take a time).
3. Turn off the bracelet from charging and wait 1 minute.
4. Reconnect and hold again for 5 minutes.
5. Try to turn on the bracelet with a button. If it does not work, repeat the cycle 2-3 times.

This method works because the power controller in the Mi Band 3 sometimes wakes up after a series of short pulses of current, and in 70% of cases the bracelet is turned on after 2-3 cycles.

Method 4: Checking through the Mi Fit app (if the bracelet is determined)

If the bracelet vibrates when connected to charging, but the screen does not turn on, try connecting to it through the official Mi Fit application. Sometimes the device “hangs” during the synchronization stage, and it can be “waked” programmatically.

Instructions:

1. Install the latest version of Mi Fit (you can download it from Google Play or App Store).
2. Sign up or sign in to your Xiaomi account.
3. Go to Profile → Add Device → Bracelet → Mi Smart Band 3
4. Follow the instructions on the screen. If the bracelet is detected but not turned on, click "Device not responding?" and select "Reconnect."

If the app sees the bracelet but it doesn’t respond to commands:

• 📱 Try updating the firmware through Device Settings → Software Update.
• 🔄 Perform a reset via the application: Settings → Untie the device.
• 🔋 Check the charge level in the app — if it shows 0% but the bracelet is on charge, it's a sign of a battery failure.

💡

If the Mi Fit doesn’t find the bracelet, but it vibrates when connected to charging, the problem is Bluetooth contacts or firmware, in which case only flashing through the Mi Band Tools (more on this below) will help.

Method 5: Flashing through Mi Band Tools (for power users)

If all previous methods did not work, but the bracelet at least somehow responds to charging (vibrates, flashes the indicator) - there is a last chance: flashing through third-party software.

• 📱 Android smartphone with Bluetooth 4.0 support.
• 🔌 Mi Band Tools app (download here).
• 💾 Firmware file for Mi Band 3 (version should match your model!)

Step-by-step:

1. Install Mi Band Tools and provide all the necessary permissions.
2. Connect the bracelet to charging and wait until it is determined in the application.
3. Go to Firmware and select Install custom firmware.
4. Download a firmware file (e.g., mi_band_3_fw_1.0.1.38.bin).
5. Start the firmware process and don’t turn off the bracelet until you see a Success message.

⚠️ Warning: Incorrect firmware can permanently kill the bracelet. Use only verified files from official sources (e.g. AmazfitWatchFaces).

If the firmware was successful, but the bracelet still does not turn on:

• 🔋 Try replacing the battery (cost is about 500-800 rubles).
• 🛠️ Contact Xiaomi Service Center – the motherboard may have failed.

What to do if nothing helps: Diagnostics of malfunctions

If the Mi Band 3 has not been activated after all the manipulations, it is likely a hardware problem.

If you are not sure about your skills, it is better to contact the professionals.Average cost of repairing Mi Band 3 in service centers:

• 🔋 Battery replacement: 600–1000 ₽.
• 🖥️ Display replacement: 1200–1500 ₽.
• 🔧 Diagnostics + Flashing - 500-800 ₽.

Before visiting the service, check if the warranty period has expired (for Mi Band 3 it is 12 months from the date of purchase).
