How to untie Xiaomi Mi Band 2 from the phone: all working ways

The 2016 Xiaomi Mi Band 2 fitness bracelet is still popular with users due to its simplicity, reliability and low price. However, over time, it becomes necessary to untie the device from the phone — whether it is selling a gadget, switching to a new model or eliminating synchronization errors. Unlike modern bracelets with NFC and advanced features, the Mi Band 2 has its own disconnection features, which are important to consider.

In this article, we will discuss all the current ways of unbundling, from standard unbundling through the Mi Fit app to forced reset via a hidden menu. Particular attention will be paid to the typical problems: when the bracelet “can’t see” the phone, freezes in the synchronization stage or requires authorization in a Xiaomi account. If you encounter one of these situations, the instructions below will help solve the problem without contacting the service center.

Why you should untie the Mi Band 2 from your phone

At first glance, the disengagement procedure seems trivial, but in practice users face the need to decouple in a variety of scenarios:

• 📱 Change of smartphone – when switching to a new phone, the bracelet remains tied to the old device, and without detachment, data synchronization will be impossible.
• 💰 Selling or transferring the bracelet – before transferring the gadget to another person, you need to delete all personal data (steps, pulse, notifications).
• 🔄 Synchronization errors – if the bracelet stopped correctly transferring data to the application, sometimes a complete reset of communication helps.
• 🔒 Reset password from Xiaomi account – if you change credentials, you may need to re-authorize the device.
• 🛠️ Update firmware - some users note that after the update, the bracelet "forgets" the binding and requires reconfiguration.

It’s important to understand that the Mi Band 2 doesn’t support multiplayer — it can only be synced to one phone and one Xiaomi account at a time. If you’re trying to connect the bracelet to another smartphone without first detaching, the system will give an error The device is already tied to another account.

⚠️ Note: After the bracelet is untied, all accumulated data (activity history, sleep statistics) will be deleted from the device and can only be stored through export in the Mi Fit app until communication is broken.

Method 1: Standard uncoupling via the Mi Fit application

The easiest and most recommended method is to use the official Mi Fit app, which is suitable if you have access to the phone to which the bracelet is attached and the app correctly recognizes the device.

Step instructions:

1. Open the Mi Fit app on your smartphone.
2. Go to Profile → My Devices (or Devices depending on the version of the app).
3. Select Xiaomi Mi Band 2 from the list of connected gadgets.
4. Slap the icon. ⚙️ (Settings) in upper right corner.
5. Scroll down and select Untie the device (or Remove the device).
6. Confirm the action in the dialog window.

After that, the bracelet will be removed from your account and you can link it to another phone, but sometimes users find that the Unplug button is inactive or absent, and this can happen for two reasons:

• 🔌 The bracelet is not connected to your phone via Bluetooth (check the connection in your smartphone settings).
• 🔄 Mi Fit is outdated (update it via Google Play or App Store).

If the standard method does not work, go to the alternative methods described below.

Method 2: Forced reset of the bracelet to factory settings

When the application is not uncoupled (e.g., if the phone is lost or the bracelet is getting stuck), the hardware reset remains, which removes all data from the device, including account binding, and importantly, once reset, the bracelet returns to its "out of the box" state and requires reconfiguration.

How to perform the reset:

1. Remove the bracelet capsule from the strap.
2. On the back, look for a touch button (under the Mi logo).
3. Connect the bracelet to the charger.
4. Press the touch button for 5-7 seconds until a Reset message or vibration appears on the screen.
5. Release the button - the bracelet will reboot and reset to factory settings.

Once reset, the bracelet will display a binding code (e.g., 1234) that you will need when you reconnect to the phone.

⚠️ Note: Some Mi Band 2 firmware may not reset the first time.If the bracelet does not respond to the hold of the button, repeat the procedure 2-3 times or try holding the button up to 10 seconds.

Method 3: Uncoupling through the web version of Mi Account (if the phone is not available)

If you don’t have access to the phone that the bracelet is attached to, but you remember the data from your Xiaomi account, you can try to delete the device via the Mi Account web interface.This method doesn’t always work, but in some cases it helps to break the communication remotely.

Instructions:

1. Go to account.xiaomi.com and log in with your account.
2. Under Devices (or Mi Cloud) look for Xiaomi Mi Band 2.
3. Click on the basket icon (🗑️) or select Remove the device.
4. Confirm the action by SMS or email.

Please note that this method may not work if:

• 🔗 The bracelet was not synced to the Mi Cloud (data is only stored locally on the phone).
• 🕒 More than 30 days have passed since the last sync (the device can be automatically removed from the list).

If the web method does not help, only hardware reset remains (described in Method 2).

How to tie Mi Band 2 to a new phone after undocking

Once successfully uncoupled, the bracelet is ready to be connected to another smartphone, and the binding process is virtually the same as the initial setup:

1. Install the Mi Fit app on your new phone and log in (or create a new Xiaomi account).
2. Turn on Bluetooth and allow the application to access geodata (required for correct operation!).
3. In Mi Fit, go to Profile → Add the device.
4. Choose Xiaomi Mi Band 2 from the list.
5. Follow the instructions on the screen: confirm the pairing on the phone and bracelet (when vibration appears, click on the touch button).
6. Enter the code from the bracelet screen (e.g., 1234) into the application.

• 📱 Remove the Mi Fit app cache in your phone settings.
• 🔌 Turn off and turn on Bluetooth again.

Once attached to a new phone, all previous data (steps, sleep, workouts) will be lost — it will not be automatically transferred. To save the story, export it manually through Mi Fit → Profile → Export data to the detachment.

Alternative applications for managing Mi Band 2

If the standard Mi Fit app is unstable or you need advanced features, you can use third-party utilities that allow you not only to untie the bracelet, but also to adjust notifications, change dials and even update the firmware manually.

Popular alternatives:

• 📱 Notify & Fitness for Mi Band – supports all Mi Band models, including the second version, allowing you to customize vibrations, notifications and export data to Google Fit.
• 🔧 Mi Bandage – a utility for PC that helps to sew the bracelet, reset settings and recover after failures.
• 🌐 Tools & Mi Band – an open source app for fine-tuning the gadget (including hidden features).

Warning: Third-party apps may require root rights or special drivers to work with the bracelet, and use them at your own risk, especially if you are not sure about the download sources.

⚠️ Note: When using unofficial firmware or utilities, there is a risk of “bricking” the bracelet (turning into a “brick”). Before experimenting, back up your data using Mi Fit.

💡

Third-party apps may offer more features, but official Mi Fit software remains the most reliable way to manage the Mi Band 2 without risking the device.
