How to completely untie the Xiaomi Mi Band 3 fitness bracelet from your phone or account

The Xiaomi Mi Band 3 fitness bracelet remains a popular gadget even years after its release, with its reliability and functionality appreciated by millions of users. However, sooner or later, there is a need to break the connection between the device and the phone: when selling, transferring to another person, changing a smartphone or eliminating synchronization errors. Unlike new models (Mi Band 7 or Smart Band 8), the third version has nuances that make the detachment process unobvious to beginners.

In this article, you will find 3 proven ways to break the connection of the Mi Band 3 with the device: through the application, reset the bracelet itself and delete from the Xiaomi account. We will also analyze the typical errors (for example, when the bracelet does not appear in the list of devices) and give recommendations for security – why you can not just “forget” the gadget in the Bluetooth settings. If you plan to sell or transfer the bracelet, be sure to read the section about the full reset before factory settings – this will save your personal data from leaking.

Why you should untie the Mi Band 3 from your phone

At first glance, the detachment procedure seems trivial: it is enough to remove the bracelet from the application, but in practice, users face the need to break the connection in a variety of situations:

• 📱 Changing your smartphone – when switching to a new phone, the bracelet can “hang” on the old account, requiring a forced reset.
• 💰 Selling or transferring a gadget – without a full decoupling, the new owner will not be able to link the Mi Band 3 to his account.
• 🔄 Synchronization errors – if data stops updating, sometimes only a complete disconnect and re-association helps.
• 🔒 Xiaomi account problems – when you change your email or password, the bracelet may lose communication with servers, requiring a reconnection.
• 🛠️ Preparation for repairs – some service centers require resetting the device before diagnosis.

It's important to understand that simply removing the bracelet from the Bluetooth device list on your phone doesn't completely break the connection. Your steps, heart rate, and sleep data remain tied to your Mi Fit or Zepp Life account, and the gadget itself can store information about the last connected phone, and to avoid personal data leaks, you need to perform a full reset — more about this in the corresponding section.

Method 1: Uncoupling with Mi Fit or Zepp Life

The most obvious and safe way to do this is to use the official app, but there are pitfalls: Mi Fit and Zepp Life are different, and in some regions only one of the programs is available, and we'll look at both.

For users of Mi Fit (older versions of the application)

If you are still using Mi Fit, follow this instruction:

1. Open the app and go to the Profile → My Devices section.
2. Click on the Mi Band 3 icon in the list.
3. In the upper right corner, tap three points (⋮) and select Remove the device.
4. Confirm the action – the bracelet will be untied from the account, but the data will be stored in the cloud (they can be deleted separately in the profile settings).

For users of Zepp Life (new versions)

In Zepp Life, the process is a little different:

1. Launch the app and go to the Profile tab (the person icon at the bottom of the screen).
2. Select My devices and find Mi Band 3 in the list.
3. Click on the device, then on the gear icon (⚙️) top-right.
4. Scroll down and select Untie the device.
5. Confirm the action by entering a password from the Xiaomi account.

After unplugging the wristband through the app, it will remain in your phone’s Bluetooth memory, and to avoid conflicts when reconnecting, we recommend that you also remove it from the list of associated devices:

1. Open the phone settings → Bluetooth.
2. Find Mi Band 3 in the list and click on the cart icon or Forget the device.

Method 2: Reset the bracelet to factory settings

If the uncoupling through the app doesn’t work (for example, the bracelet doesn’t appear in the list of devices) or you transfer the gadget to another person, you need to perform a full reset.This will delete all data from the Mi Band 3, including:

• 📊 History of activity (steps, calories, sleep).
• ❤️ Heart rate data.
• 🔔 Notification and alarm settings.
• 🔑 Linking to Xiaomi account.

You don’t need a phone to reset – everything is done directly on the bracelet:

1. On the Mi Band 3 screen, swipe up to open the menu.
2. Scroll down to the option (or More in English).
3. Select Reset.
4. Confirm the action by clicking on the tick (✓). The bracelet will reboot and return to factory settings.

Once reset, the bracelet will display the Mi logo and request re-assignment, and can now be connected to a new phone or account.

⚠️ Warning: Once reset, all data from the bracelet will be permanently deleted. If you plan to continue using it, pre-sync the history with the application.

Method 3: Remove the bracelet from the Xiaomi account

In some cases (e.g., when you change your email or delete your account), the Mi Band 3 can remain attached to your old profile even after you reset. To completely disconnect, you need to remove the device from your Xiaomi account:

1. Go to account.xiaomi.com and log in.
2. In the Devices section, find Mi Band 3.
3. Click on the three dots next to the device and select Remove.
4. Confirm the action by entering a password.

If the bracelet is not displayed in the web version of the account, try:

• 📱 Use the Mi Account mobile app (available for Android and iOS).
• 🔄 Update the page or clear the browser cache.
• 📧 Make sure you are logged in to the correct account (sometimes users confuse primary and backup email).

After deleting the bracelet from your account, it will be completely untied from your profile, and it can be linked to another user.

💡

If you are selling a bracelet, before deleting from the account, take a screenshot of the activity history - this will help prove its performance to the buyer.

Common mistakes and their solutions

When uncoupling Mi Band 3 users often face typical problems, we have collected the most common of them and ways to fix them:

⚠️ Note: If the bracelet doesn’t untie after all the manipulations, it may be tied to another region (for example, bought abroad.

How to check if the bracelet is completely untied

Before you transfer the Mi Band 3 to another person or start using it on a new phone, make sure that the connection is broken correctly.

1. Try tying the bracelet to another phone: Install Mi Fit or Zepp Life on a second smartphone. Register a new Xiaomi account (or use an existing one). Try adding Mi Band 3 via Add Device. If the bracelet is successfully connected, the connection is severed. If not, reset again.
2. Check your data history: Open the old app and see if the activity history is updated. If the data keeps coming in, the bracelet is untied.
3. Make sure the bracelet doesn’t show up in your account: Go to account.xiaomi.com. Check Devices section – Mi Band 3 shouldn’t be listed there.

If the bracelet has been dropped, but when you try to link to a new phone, it gives an error "The device is already tied", then it is still associated with the old account. In this case, contact Xiaomi with the serial number (located on the back of the case).

Security: What to do before selling or transferring the bracelet

Many users overlook the fact that the Mi Band 3 stores personal information, from sleep history to location data (if GPS features were used over a phone).

• 🔐 Delete all data from your account: Open Mi Fit/Zepp Life. Go to the profile. → Settings → Delete data. Choose Delete all data and confirm.
• 📱 Untie the bracelet from all phones: Remove it from the list of Bluetooth devices on all smartphones it connected to.
• 🔄 Complete reset: As described in Method 2, reset the bracelet to factory settings.

Check the physical condition:

1. Make sure there are no scratches or damages on the case that could raise questions from the buyer.
2. Wipe the bracelet with an alcohol napkin - this will eliminate traces of use.

If you sell the bracelet on sites like Avito or OLX, indicate in the description that the device is completely reset and ready for a new binding, which will increase customer confidence and speed up the transaction.

💡

Even after resetting, the bracelet can store data about the last phone connected in its memory, so to erase it, link to your smartphone and reset again.
