Untieing a Xiaomi fitness bracelet from a smartphone or Mi Account can be necessary in a variety of situations: you sell a device, transfer it to a relative, have experienced synchronization errors or just want to change your phone. However, many users face problems - the bracelet does not untie through the application, requires a password from an old account or completely “hangs” in the process. In this article, we will discuss all the working ways of untieving for Mi Band 3/4/5/6/7 models, Mi Smart Band 7 Pro and newer ones, and also tell you how to avoid typical mistakes.
It is important to understand that the procedure differs depending on whether you want to simply disconnect from your phone (to connect the bracelet to another device) or completely remove it from your Mi/Xiaomi account (for example, before selling). In the first case, standard in-app actions are enough, in the second case, you may need to reset to factory settings.
1.Preparation: What to do before untiing the bracelet
Before you start to unplug, follow a few mandatory steps to avoid data loss and reconnection problems:
- 📱 Sync your data in the Mi Fitness app (formerly Mi Fit) or Zepp Life. Open your bracelet profile and wait until sync is complete to avoid losing your activity history.
- 🔋 Charge the bracelet to at least 50%. Resetting or long-term operations can drain the battery, which will lead to a failure.
- 📡 Check your phone’s internet connection. Account detachment requires access to Xiaomi servers.
- 📝 Record or take pictures of your bracelet’s current settings (alarm clocks, notifications, training profiles) if you plan to reconnect it.
If you untie the bracelet for sale, be sure to reset to factory settings (instruction in Section 4) this will delete all personal information, including health data and tied payment cards (for models with NFC).
⚠️ Note: If the bracelet is tied to a Mi Account you no longer use (such as an old phone number or email), you won’t be able to untie it in the standard way.
2. Method 1: Untie the bracelet through the application Mi Fitness/Zepp Life
The easiest and recommended way is to use the official app. The instructions are suitable for all modern Xiaomi bracelet models, including the Mi Band 5/6/7 and Mi Smart Band 7 Pro.
Steps for detachment:
- Open the Mi Fitness app (or Zepp Life if you have a new firmware).
- Go to the Profile section → My devices.

3. Method 2: uncoupling through phone settings (Android)

If you do not delete the cards in advance, they will remain in the memory of the bracelet, which is not safe when transferring the device to another person.
⚠️ Note: Some models (e.g. Mi Band 7 Pro) may require re-activation of the feature after reset. NFC Please check this in advance if you plan to continue using the bracelet.
7.How to check if the bracelet is successfully untied
After performing any of the procedures, we recommend that you make sure that the bracelet is truly untied.
- 🔍 Check the list of devices in Mi Fitness – the bracelet should not be there.
- 📱 Try connecting the bracelet to another phone, and if it appears on the list of available devices, the undressing was successful.
- 🔄 Reset the bracelet (press the button for 5 seconds). After rebooting, it should request a new binding.
If the bracelet is still tied to your old account, repeat the reset (Section 4) or contact Xiaomi with proof of purchase.
