Owning a modern activity tracker often involves reconnecting your device to new gadgets or transferring it to another user. Many smart accessory owners face a situation where a standard Bluetooth shutdown doesn't solve the data synchronization problem. If you plan to sell your tracker, give it to a friend, or just switch to another smartphone model, you need to know how to untie the Xiaomi wristband from your phone correctly to avoid pairing errors in the future.
The procedure for breaking the connection between a wearable gadget and a mobile device is not always obvious, since simply turning off a Bluetooth module is not enough. Deep data cleaning requires a series of sequential actions within a specialized application and operating system settings. Ignoring certain steps can lead to the device remaining “fixed” to the old account, making it impossible to activate it on the new device without completely resetting.
In this article, we will take a closer look at the nuances of working with the Mi Home and Zepp Life ecosystem, explain the difference between simple shutdown and complete deletion. You will learn how to clear the cache, delete records about Bluetooth devices and perform a hardware reset if the software methods do not work. This guide will help you avoid typical errors and keep your tracker running.
Why you need to perform a complete decoupling of the device
Many users mistakenly believe that it is enough to simply stop using the app or turn off Bluetooth on an old gadget to change the phone, but the architecture of smart bracelets is built on a rigid binding to the unique identifier of the account and the user’s identity. MAC-If you don't do the detachment procedure correctly, the new smartphone can see the device, but it won't be able to establish a stable connection or synchronize health data with it.
This is especially critical in situations where the device is transferred to another person, and as long as the tracker is listed on your profile, the new owner will not be able to register it on his account. Xiaomi’s security system sees the attempt to connect to a “busy” device as potentially dangerous or mistaken, and conflicts often arise without cleaning old records. IP-addresses and permanent communication gaps.
⚠️ Warning: Trying to connect the bracelet to a new phone without first deleting from your old account leads to a 90% error: Device is occupied».
Also, a complete uncoupling is necessary when selling a device: a buyer should get a “clean” gadget ready for the first setup. If your personal data is left on the tracker or it is tied to your account, this can jeopardize your privacy. Deleting the device from the trusted list is a basic element of digital hygiene and personal data security.
Preparing for removal of the device from the system
Before you start the deletion process, you need to make sure that all important data is saved. Although Xiaomi cloud services usually sync statistics automatically, before breaking the connection, it is recommended to perform manual synchronization. Open the application you use to manage the tracker (most often it is Zepp Life or Mi Fitness), and wait for the update of all the metrics for the current day.
Make sure your smartphone and bracelet are in close proximity to each other. The distance should not exceed 1-2 meters so that the commands are transmitted instantly and without distortion. If the tracker battery is less than 20% discharged, it is better to put it on charge. Interrupting the removal process due to battery discharge can lead to a software failure, after which the device will have to reflash.
☑️ Preparation for uncoupling
It’s also worth checking which version of the app is installed on your phone. The menu interface on different versions of Zepp Life or Mi Fit may vary slightly, but the logic of actions remains the same. If you have several applications installed to manage Xiaomi devices, determine which one is the main one for your bracelet so you don’t get confused in the settings.
Instructions: Delete via the Zepp Life app (Mi Fit)
The most common and correct way to unplug the tracker is to use the functionality of the app itself, which allows you to break communication at the server level, not just locally on the phone. To start, open the Zepp Life app (formerly known as Mi Fit) on your smartphone. Go to the Profile tab, which is usually located in the lower right corner of the screen.
In the list of My devices, find an image of your bracelet. Click on it to enter the control menu of a particular gadget. Scroll down to the bottom where you find the Unlink or Unlink button. The system will issue a warning that all data will be deleted from the device but will remain in the cloud. Confirm the action by entering your account password or confirmation code if necessary.
After successful detachment, the device will be changed to "Not Connected" and then it will disappear from the list of active gadgets. The bracelet screen may show vibration or reset animation, confirming that the connection with the server is severed.
⚠️ Warning: After detachment through the application, all settings of alarm clocks and reminders on the bracelet will be reset to factory values.
What to do if the “untie” button is inactive?
Cleaning Bluetooth connections in Android and iOS settings
Even after removing the device from the application, the record of it often remains in the system menu of the Bluetooth smartphone. This can interfere with the correct operation, as the phone will try to automatically restore the connection to the device already removed from the profile.
On Android devices go to Settings → Find the name of your bracelet on the list of available devices (usually a “Mi Band” with a model number or a “Mi Band”). MAC-Click on the gear icon or information icon next to the name and select "Forget device" or "Unpair." On iOS, the actions are similar: Settings → Bluetooth, click on the “i” symbol and select “Forget this device».
It's important to do this for all the phones that the bracelet has ever connected to, and if you've used your tablet or your spouse's phone, clear your connection history there, too, so that when you turn on the bracelet, it doesn't automatically look for the old devices, ignoring the new phone you're trying to tuck it into.
| Action. | Android | iOS (iPhone) |
|---|---|---|
| The path to the menu | Settings → Bluetooth | Settings → Bluetooth |
| Device-related activities | Push the gear. → Forget it. | Push "i» → Forget the device |
| Extra cleaning | Settings → Applications → Zepp Life → Clear the cache | Remove and reinstall the application |
| Reboot. | Requires a Bluetooth reboot | Enough off/on module |
Once the Bluetooth list is cleared, it is recommended to restart the smartphone, allowing the operating system to completely reset the cache of Bluetooth services and start searching for devices from scratch, an approach that is especially effective if you are facing visibility problems.
💡
If the bracelet doesn’t disappear from the Bluetooth list after being removed in the app, try turning off Bluetooth on your phone, rebooting the bracelet itself (if there’s such a feature on the menu), and only then turning on Bluetooth again.
Hardware reset of Xiaomi bracelet to factory settings
In situations where the application is removed, the phone is lost or software unbundling is impossible, the only reliable method is hardware reset, which returns the device to the “out of the box” state, removing all user data and resetting the account.
To perform a reset via the device menu (relevant for Mi Band 6, 7, 8 and more new models):
1. Wake up the bracelet screen.
2. Swipe, find the item "Settings" (the gear icon).
3. Scroll through to the "System" item or immediately find "Reset".
4. Confirm the action by clicking the tick. The device vibrates and reboots.
Older models that don't have a full reset menu, or if the sensor doesn't respond, may require a charger connection. Some models reset when the touch button is held for a long time while connecting to charging, but this method depends on the specific firmware modification. In most cases, just find Settings → System → Factory Reset in the tracker interface.
⚠️ Warning: Hardware reset deletes all data accumulated since the last sync.If you haven't opened the app in a long time, steps and heart rate can be lost forever.
💡
Hardware reset is a “nuclear” method that is guaranteed to untie the device, but erases the entire local activity history.
Solving typical problems in unbundling
Despite the simplicity of the procedure, users often face technical difficulties. One of the most common problems is that the bracelet hangs in the connection status, and the application says, "Device is not responding." In this case, it helps to force the application to stop. Go to the phone settings → Apps → Zepp Life (or Mi Fit) → Forced stop, then start the application again and try to untie the device.
Another common situation is that the bracelet is untied, but when you try to connect it to a new phone, it is not in search mode. Most likely, the device is in "sleep" mode or trying to connect to an old phone. Make sure that the old Bluetooth phone is turned off and the bracelet is restarted. Sometimes you need to quickly press the touch button (if the model allows) or put the bracelet on charge to activate visibility mode.
If nothing works, use the Device Search feature in the app before uncoupling, this will force you to establish a connection and update status. Also check the permissions: the app must be allowed access to geolocation and Bluetooth, otherwise in modern versions of Android (10-14) it will not be able to control the device correctly.
- 🔄 Reboot Services: Turn on and off "Flight Mode" on your phone to reset network modules.
- 🗑️ Clean installation: Remove the app completely, download the latest version from the official website or store and try again.
- 📱 Change your account: Try logging out of your Mi Account and logging in under another to check if your device is locked at the server level.
In rare cases, the problem lies in the firmware version of the bracelet itself, if the device has not been updated for a very long time, it may not work properly with new versions of the application. Try updating the firmware of the bracelet through the application before you uncouple.
