How to turn on Xiaomi Mi Band 4 after a complete reset: 5 working ways

After resetting the Xiaomi Mi Band 4, many users face a problem: the bracelet stops responding to clicks, does not turn on or hangs on the logo. The reasons can vary from a dead battery to software failures in the firmware. In this article, we will discuss all possible ways to turn on the device, and also explain how to avoid typical errors when restoring the gadget.

It's important to understand that resetting to the Mi Band 4 isn't always smooth. In some cases, the bracelet requires a forced reboot or even a flash flash. We've put together proven methods to help bring the device back to life, from simple manipulations to sophisticated technical solutions. If you've tried charging the bracelet but it still doesn't show signs of life, read on.

Why Mi Band 4 doesn't turn on after reset

Before you try to turn on the bracelet, you should understand the causes of the malfunction, most often the problem lies in one of the following factors:

🔋 Battery discharge – even after being connected to charging, the device may not react due to deep discharge.
🔄 Incomplete resetting of settings – if the procedure was interrupted, the firmware could be damaged.
📱 Mi Fit application problems – outdated version of the program or synchronization errors.

The most common reason is a deep battery discharge, where standard charging doesn't work, which requires you to force the bracelet to wake up, and if the firmware is a problem, you might need to flash it through some special utilities.

⚠️ Warning: Do not try to disassemble the bracelet yourself to check the battery - this will lead to a loss of warranty.

Method 1: Forced resetting of the bracelet

If the Mi Band 4 doesn't respond to pressing, but you're sure it's charged, try a hard reset, which works in 70% of cases when the bracelet freezes after reset.

Instructions:

Connect the bracelet to the charger and wait until the charging indicator appears on the screen (if it does not burn, leave on charging for 30-60 minutes).
Unplug the bracelet from charging.
Press the touch button under the screen for 10-15 seconds until you feel vibration.
Release the button – the bracelet should reboot and show the Mi logo.

If the device does not turn on after that, repeat the procedure 2-3 times. Sometimes it takes up to 5 attempts for the bracelet to react.

Leave the bracelet on charge for at least 30 minutes |

Method 2: Charging in "recovery mode"

If the bracelet is completely discharged and does not respond to charging, try an alternative method of connection.

You'll need:

🔌 Smartphone charger (5V/2A).
🔗 USB-Type-A cable (from old phone or power bank).
📌 paperclip.

Algorithm of action:

Disconnect the standard charging cable from the bracelet.
Take a paper clip and carefully close the contacts on the bracelet connector (two metal pins) for 1-2 seconds.
Without releasing the clip, connect the bracelet to charging via USB-Type-A cable.
Hold the circuit for another 5-10 seconds, then release.

If the method works, the charge indicator will appear on the screen. Leave the bracelet to charge for 2-3 hours, then try to turn it on in the standard way.

⚠️ Warning: Do not close contacts for more than 2 seconds in a row - this can damage the power controller.If after 3 attempts the bracelet does not respond, stop manipulating.

What to do if the bracelet heats up during charging?

If the body of the Mi Band 4 is very hot (above 40°C), immediately disconnect it from charging. This may indicate a malfunction of the battery or controller, in which case it is recommended to contact the service center, as further attempts to charge can lead to fire.

Method 3: Recovery through the Mi Fit app

If the bracelet is switched on but not synced to the phone, the problem may be reset communication settings, in which case re-assignment through the official app will help.

Step-by-step:

Remove the bracelet from the list of devices in Mi Fit (if it is still listed there).
Reinstall the Mi Fit app (sometimes cache cleaning helps).
Launch the app and select Add Device → Mi Smart Band 4.
Follow the instructions on the screen when required – click on the touch button of the bracelet.
Wait until the synchronization is complete (it can take up to 5 minutes).

If the bracelet is not detected, try:

📱 Reboot your smartphone.
🔄 Turn Bluetooth on/off.
📋 Install an alternative app, such as Notify & Fitness for Mi Band.

FAQ: Answers to Frequent Questions

My Mi Band 4 doesn't turn on after reset, but vibrates when connected to a charger. What do I do?

If the bracelet vibrates but doesn't turn on, it means it's getting power but can't load the firmware. Try: Hold the touch button for 20 to 30 seconds to force reboot; plug the bracelet into the Mi Fit and wait for the firmware update suggestion. If nothing helps, hand-stitch the bracelet (see Method 4).

Once reset, the bracelet turns on, but it doesn't sync with the phone. What's the matter?

The problem could be: Outdated version of Mi Fit (update the app); conflict with other apps (disable Google Fit, S Health); Bluetooth failure (reboot phone and bracelet); try removing the bracelet from Mi Fit and adding it again.

Can I recover the data (steps, pulse) after resetting?

Unfortunately, all the local data on the bracelet is deleted when you reset. However, if you had Mi Fit sync enabled, some of the statistics could be saved to the cloud. To recover: Open Mi Fit and check the activity history. If there is data, it automatically syncs with the bracelet after the binding. If the sync was not configured, the data is lost irrevocably.

How long does the Mi Band 4 charge after a deep discharge?

In deep discharge, the first charge can take up to 3-4 hours, as the power controller first “wakes up” the battery and then charges it as normal.

Where to download the official firmware for Mi Band 4?

Official firmware is distributed through: Mi Fit App (automatic update); Xiaomi Community Forum (c.mi.com); Zepp Life website (for global versions); Warning: Download firmware only from trusted sources; files from torrents or unknown sites may contain malicious code.
