How to untie the Xiaomi bracelet from the phone: 5 proven ways

Xiaomi fitness bracelets are some of the most popular wearables on the market, but sometimes it becomes necessary to untie them from the phone. The reasons can be different: selling the bracelet, switching to a new smartphone, resetting settings or fixing synchronization errors. In this article, we will discuss all the current ways to detach the Mi Band, Smart Band and other models from the phone, including nuances for different versions of firmware and applications.

Many users have trouble trying to break the connection between the wristband and smartphone. For example, the Mi Fitness app (formerly Mi Fit) may not show the detachment option, or the wristband continues to automatically connect to the old device. We will look not only at standard methods, but also at alternative solutions for complex cases.

If you're planning to hand over the wristband to another person, or just want to start with a clean slate, it's important to understand that it's not enough to just uninstall the app. Without the right uncoupling, the new owner won't be able to tie the device to their phone, and you risk losing access to health data.

1. Standard uncoupling through the Mi Fitness app

The easiest and most recommended way is to use the official Mi Fitness app, which works for most bracelet models, including the Mi Band 3/4/5/6/7/8, Smart Band 7 Pro and newer versions.

1. Open the Mi Fitness app on your smartphone.

2. Go to Profile → My Devices (or Devices depending on the version of the application).

3. Select your bracelet from the list of connected gadgets.

4. Scroll down and click on the option Untie the device (or Remove the device).

5. Confirm the action in the window that appears.

After that, the bracelet will be disconnected from your Xiaomi account and you can link it to another phone, but note that some models (such as the Mi Band 7 and newer) may require additional resetting on the bracelet itself.

Make sure the bracelet is charged (minimum 20% charge)

Turn on Bluetooth on your phone

Update the Mi Fitness app to the latest version

Remember the Xiaomi account details (they will be required to re-link)-->

Important: If the Untie Device option is inactive or not, it may mean that the bracelet is already disconnected from the account, but stored in the list of devices, in which case try the methods in the following sections.

2. Uncoupling through resetting settings on the bracelet

If the standard method didn’t work or you can’t access the application, you can perform a hardware reset directly on the bracelet, which is suitable for all Mi Band and Smart Band models, but the process may vary slightly depending on the version.

For most bracelets (e.g. Mi Band 5/6/7):

1. On the bracelet screen, swipe down to open the menu.

2. Find the Settings icon (cog) and select it.

3. Scroll to Reset Settings or Restore Factory Settings.

4. Confirm the reset by clicking on the tick or the corresponding button.

For the Mi Band 3/4:

1. Click on the touch button below the screen to open the menu.

2. Find the section Additional → Reset.

3. Confirm the action by pressing the button long.

Once reset, the bracelet will automatically disconnect from all devices and be ready for a new binding, but note that this method removes all data from the bracelet, including activity history and settings.

💡

If the bracelet does not respond to touch, connect it to charge for 10-15 minutes. Sometimes a discharged battery blocks access to the reset menu.

3. Uncoupling through Xiaomi account on the website

If you don’t have access to the phone that tied the bracelet to, or the Mi Fitness app doesn’t work, you can try untie the device via the web version of your Xiaomi account, a method less well known but often helpful in difficult situations.

1. Go to the official account.xiaomi.com and log in under the same account to which the bracelet is linked.

2. Under Device Management (or Mi Cloud → Devices), find your bracelet in the list.

3. Click on the basket icon or select the option to Remove the device.

4. Confirm removal.

This method does not work for all wristband models, as some devices (such as the Smart Band 7 Pro) may not appear in the web version of your account.

4. Uncoupling through another device (if the bracelet is tied to multiple phones)

Sometimes the Xiaomi bracelet can be tied to multiple smartphones at the same time (for example, if you used it with a work and personal phone), in such cases, the severance through one device may not work, as the connection is saved through another.

1. Make sure the bracelet is not connected to other phones. To do this, check the list of conjugated devices in the Bluetooth settings on all smartphones it has previously worked with.

2. If you find the bracelet in the list of associated devices, delete it (Forget the device in Bluetooth settings).

3. perform a reset on the bracelet (as described in Section 2).

After that, the bracelet will be fully untied and ready for a new binding. If you don't remember which phones it was connected to, use the reset method through the app or Xiaomi account.

What if the bracelet automatically connects to the old phone?

If the bracelet is reconnected to the previous smartphone after detachment, it means that it is stored in the Bluetooth memory of the phone. To avoid this: 1. On the old phone, remove the bracelet from the list of associated devices (Settings → Bluetooth → Forget the device). 2. Disable Bluetooth on the old phone while you are attached to the new device. 3. Reset the network on the bracelet (if such an option is on the menu).

5. Uncoupling through Developer Mode (for experienced users)

If standard methods don't work, you can try untie the bracelet through the developer mode in the Mi Fitness app, which is suitable for advanced users and requires caution.

1. Open the Mi Fitness app and go to Profile → Settings → About the program.

2. Click 5-7 times on the line with the version of the application until the message You became a developer appears.

3. Go back to the basic settings and find a new section for developers.

4. Enable the Bluetooth Debugging option (or ADB-debugging).

5. Connect the bracelet to your computer via ADB and execute the command:

adb shell am start -n com.xiaomi.hm.health/com.xiaomi.hm.health.device.UnbindDeviceActivity

This method requires having ADB on your computer and basic command line knowledge, and if you're not sure what you're doing, you'd better use other methods.

💡

Developer mode allows you to untie the bracelet even if standard options in Mi Fitness are not available, but improper actions can lead to malfunctions in the device.

6. What should I do if nothing helps?

If none of these methods worked, you may have a problem with the bracelet firmware or a conflict with your Xiaomi account.

✅ Update the bracelet firmware through the Mi Fitness app. Sometimes sync errors are fixed after the update.

✅ Check your account region. Some features may not be available if the region in your Xiaomi account is not the same as the region of your bracelet (e.g., a bracelet for China is tied to your European account).

✅ Contact Xiaomi Support If the bracelet is locked or tied to someone else's account, you may need to officially unlock.

As a last resort, if the bracelet has completely stopped responding to commands, it may need to be firmwareed through a computer, but this is a risky process that can lead to a loss of warranty.

💡

Before you run through your computer, make sure you have a backup of the data from the bracelet.Use official tools like the Mi Flash Tool and follow the instructions for your model.
