Changing a smartphone, reselling a fitness tracker or a banal malfunction in the application are just a small part of the situations when the user needs to completely untie a wearable device. Owners of the popular Xiaomi Mi Band 3 model often face nuances that are not obvious when superficially familiar with the interface. Simply turning off Bluetooth in the phone settings is not enough here, since it does not break digital communication in the manufacturer's cloud services.
Incorrect termination of a communication session can lead to the fact that the gadget will stop seeing the new phone or, conversely, will try to sync with the old account. To avoid losing accumulated statistics or problems with re-assignment, you must strictly follow the established protocol of actions within the software.
Modern smart device ecosystems like MIUI and Xiaomi Account services create a tight link between hardware and account, which is why the disconnection process requires attention to detail, especially if you plan to transfer the tracker to another person. Ignoring certain steps can block the functionality of the wristband for the new owner.
Why you need a complete disconnection from the device
Many users mistakenly believe that it is enough to simply install an app on a new gadget and click on “device search.” However, the Mi Fit architecture (now Zepp Life) is designed so that the bracelet is rigidly tied to a particular account. Until this connection is broken software, the device will ignore pairing requests from other smartphones.
There are also situations where a software failure causes the connection status to freeze, the bracelet may indicate that it is connected, but the data will no longer be updated, in which case forced unbundling through the application menu is the only working way to resuscitate synchronization without completely resetting the settings of the tracker itself.
It is also important to consider the security aspect of personal data: the device stores your activity history, pulse and sleep. When selling or transferring the Mi Band 3 to third parties, it is critical to remove all traces of your presence, which ensures that the new owner does not access your personal health statistics through cloud services.
⚠️ Before starting the procedure, make sure that the last sync was successful.If you simply remove the device from the list without first saving data in the cloud, all accumulated activity history can be lost irretrievably.
Preparation for the tracker detachment procedure
Before you start to take action in the application interface, you need to perform a number of preparatory steps, this minimizes the risk of errors and ensures that the process goes smoothly, first check the battery level on the bracelet and smartphone.
A stable Bluetooth connection is a key success factor. If communication is interrupted at the time of handing over the removal command, the device may go into an uncertain state requiring a complex reset, make sure you are in a confident reception zone, in close proximity to the phone.
It is also worth checking the relevance of the version of the Zepp Life app (formerly Mi Fit), developers regularly update the code, and old versions may contain bugs that prevent the correct removal of device profiles.
- 🔋 Charge your bracelet and phone to at least 50% for stable operation.
- 📶 Make sure Bluetooth is on and the device is visible within radius 1-2 meters.
- 🔄 Update the Zepp Life app to the latest version via Google Play or App Store.
- 📱 Close background applications that can use the Bluetooth module.
Step-by-step: Delete via the Zepp Life app
The main and most correct way to unplug the Xiaomi Mi Band 3 is to use the standard functionality of the mobile application, which ensures that all server records are updated, and the device goes into a waiting mode for a new pairing, the process begins with the launch of the program on the smartphone.
After you sign in to your account, go to the Profile tab, which is usually located in the lower right corner of the screen. This shows a list of all the gadgets connected. Find your Mi Band 3 in the list and click on it to open the device management page. The interface may vary slightly depending on the OS version, but the logic remains the same.
☑️ The decoupling algorithm
In the management menu that opens, you scroll down to the bottom of the list of options, and you'll have a red button or a text link called Unbind, and you'll click on it, and you'll get a warning that the data will be deleted from the device but will remain in your account.
Importantly, after this action, the bracelet will return to factory settings.The tracker screen will go out and light up again with the welcome MI logo, waiting for pairing.If this does not happen and the bracelet continues to show time, try rebooting it through the settings menu on the tracker itself.
Solving the problem: if the bracelet is not removed
Sometimes users are faced with a situation where the “Untuck” button is inactive, pressed, but nothing happens, or the application gives a network error. This is a common problem associated with de-synchronization of the cache or conflict of processes in the Android or iOS operating system.
The first step in this situation is to clear the app cache. Go to your phone's settings, find the Apps section, select Zepp Life and click Clear Cache. Don't confuse it with clearing the data, otherwise you'll have to re-enter your username and password. After clearing the cache, reboot your smartphone and try to repeat the procedure.
⚠️ Warning: Do not attempt to “forget the device” in your phone’s Bluetooth settings before you uncouple the app, which will cause the app to consider the bracelet connected and the phone not, creating a conflict that is difficult to resolve.
If the software methods don't work, you can use a radical but effective way of resetting the wristband itself through the menu. On the Mi Band 3, this is done by swiping left to More, then selecting Unbind, and once confirmed on the tracker screen, the connection will be forcibly severed.
- 📱 Clear the Zepp Life app cache in your phone settings.
- 🔄 Reboot your smartphone and turn on Bluetooth again.
- 🗑️ Use the “Untie” function in the menu of the bracelet itself.
- 📶 Make sure that no other fitness apps are running on your phone.
Features of decoupling when changing an account
A situation where a user wants to change not only his phone, but also his account (for example, switching from a personal account to a corporate one or creating a new profile) requires a special approach. Simply uncoupling the device here will not help, since the serial number of the bracelet can be “fixed” to the old profile in the Xiaomi database.
In this case, the algorithm is expanded. After the standard decoupling in the application, you need to go to the profile settings and make sure that the device has disappeared from the list of available ones, only then you can log out of the account and log in under the new data. If you try to add the bracelet immediately, the system may require proof of ownership through the old account.
For owners of devices with Find My Band activated, the procedure can be complicated, and some firmware versions require that this feature be disabled before unplugged to remove the activation lock, a security measure to prevent the device from being stolen.

Comparison of decoupling methods and their consequences
There are several ways to break the link between your phone and tracker, but they have different implications for data and settings. Understanding these differences will help you choose the best option for your particular situation. Below is a table comparing the basic methods.
| Method | Data retention | Resetting bracelet settings | Recommended application |
|---|---|---|---|
| Through the application (Profile) | Yeah (in the cloud) | Yes (full) | Sale, transfer to another person |
| Forgetting the device in Bluetooth | No (risk of loss) | No. | Only to eliminate communication errors |
| Reset via the bracelet menu | No (locally) | Yes (full) | If the phone is lost or broken |
| Deleting Xiaomi account | No (removing everything) | Yes. | A complete abandonment of the ecosystem |
As you can see from the table, deleting through the in-app profile is the most secure and complete method, ensuring that the data remains at your disposal (in your account history), and the device is cleared for new use.
Using the Forget Device feature in Bluetooth settings without pre-decoupling in the app is the most common error leading to problems.The bracelet continues to think it is connected and can block incoming notifications, thinking that communication is active even though the phone has already severed the connection at the protocol level.

💡
The right uncoupling is always a two-way process: action in the application + confirmation on the device, and ignoring any of the steps leads to synchronization errors.
