Modern fitness trackers and smartwatches have become an integral part of the digital ecosystem of millions of users. Devices from Xiaomi and the sub-brand Amazfit collect huge amounts of data on health, pulse and physical activity, synchronizing them with a smartphone via Bluetooth. However, sometimes there is an urgent need to break this digital connection. The reasons may be different: selling a gadget, transferring it to another family member, switching to a new smartphone model or a banal attempt to eliminate software failures in the tracker.
The shutdown procedure is not always limited to simply turning off Bluetooth in the operating system settings. To properly complete the communication session and clean the device’s memory, a number of actions are often required within specialized applications. The wrong approach can lead to the watch continuing to try to connect to the old phone or remaining “tied” to the account, which will create problems when reconfiguring. In this article, we will discuss in detail all existing methods of disconnecting the connection.
It's important to understand that the Mi Band, Mi Watch and Amazfit's connectivity architecture has its own characteristics: you can remove your device from the Bluetooth list, and you can have a mandatory reset through your profile menu, and we'll look at the algorithms for different use cases, including when the app is unavailable or your phone is lost, and carefully following the instructions will help you avoid errors and keep your data safe.
Preparing for disconnection and data retention
Before you start actively breaking the connection, you need to make sure that all the important information is stored. Data synchronization is a two-way process, and once the device is uncoupled, your workout history or sleep metrics may become unavailable in the application if they were not transmitted to the server. So the first step should always be to check the synchronization status.
Open the app you use to manage your watch (this could be Mi Fitness, Zepp Life or Amazfit). Scroll down the main screen before the update indicator appears and wait until the process is complete. Make sure the last sync time is right now. If you see the cloud icon or arrow icon, it means that data is being exchanged right now.
💡
Before setting the clock, forcefully open the app and pull the screen down to update the data – this ensures that your last steps and pulse are stored in the cloud.
Also worth paying attention to the state of battery charge. Although shutting down usually does not require much power, suddenly turning off the clock during the reset process can lead to software errors. If the charge level is critically low, it is better to put the tracker on charge before starting the procedure.
Standard detachment procedure through an annex
The most correct and safe way to disconnect the watch from the phone is to use the functionality of the companion app itself, a method that ensures that the device not only breaks the Bluetooth connection, but also clears the internal settings back to factory status. The algorithm for actions can vary slightly depending on the software version.
Consider the step-by-step process for current versions of Mi Fitness and Zepp Life. Most of the time, the interface is logically built, and the desired option is hidden in the device profile, and it's important not to confuse removing the application with removing the device from the list.
- 📱 Launch the app on your smartphone and go to the Profile or Device tab, which is usually located in the lower right corner of the screen.
- 🔗 From the list of associated devices, select your watch or bracelet. Click on the model name to open the detailed control menu.
- 🗑️ Scroll down the options list, and it should have a Unlink or Delete Device button, and some versions of the interface might call it Reset Settings».
- ✅ Confirm your actions in a pop-up window, and the system will warn you that all data will be deleted from the clock.
☑️ Checklist of detachment
After performing these actions, the clock should emit a vibration signal and reset, suggesting that you choose a language or display a different language. QR-This means that the device is successfully cleaned and ready for sale or new setup. If this does not happen, you may need manual intervention through the Bluetooth settings.
Delete the device via Bluetooth settings
Sometimes the standard app method doesn't work, and this can happen if the app is stuck, the watch is out of reach, or the Bluetooth stack on the Android or iOS operating system has failed, and you have to act directly through the system settings on your smartphone.
Go to your phone’s Settings and find the Bluetooth section. In the list of available and previously connected devices, find your tracker’s name (such as Mi Band 6 or Amazfit GTS). Click on the gear icon or arrow next to the device name to open additional options.
⚠️ Warning: Simply removing from the Bluetooth list does not always reset the clock completely.The device may remain in a state when it "remembers" the last connection and when turned on will try to find the phone again.
Select the option “Forget device” or “Unpair pairing” and then the phone will stop seeing the clock and the connection will be severed, however, to completely clean the data on the tracker itself, it is recommended to reset through the device’s menu, if such a function is provided there.
In some cases, especially on iOS, it may be necessary to remove the device from the My Devices list in the settings of the health app itself if it remains there.This will help avoid confusion in the future when you decide to reconnect the watch.
Resetting settings directly on the clock
If the phone is lost, broken or the app is removed, the only way to turn off the watch is to use its own interface. Modern models Xiaomi and Amazfit have sufficiently advanced menus that allow you to perform a complete reset without the participation of a smartphone.
To do this, wake up the watch screen and find the settings menu (usually indicated by the gear icon). In the list of options, look for System, Settings or Additional. Inside this section should be the option Reset or Factory Reset.
What to do if the menu on the clock does not respond?
Pressing the reset button initiates the process of cleaning the internal memory. Importantly, during this process, you can not remove the clock from charging or allow it to discharge. Interrupting the procedure can damage the firmware, after which it will be extremely difficult to restore the device to work.
Once the reset is complete, the watch will return to the “out of the box” state, and a welcome message will appear on the screen or QR-From now on, the device is completely disconnected from any phone and ready for a new pairing.
Comparison of methods of disabling devices
To make it easier for you to choose the right way, we have systematized information about different methods of disconnection, each of which has its advantages and disadvantages depending on your particular situation.
| Method | We need a phone. | Stores data in the appendix | Total reset of hours |
|---|---|---|---|
| Through the app | Yes. | Yes (automatically) | Yes. |
| Through Bluetooth. | Yes. | No (risk of loss) | Partially. |
| Reset on the clock | No. | No. | Yes. |
| Deletion of account | Yes. | No (data deleted) | Yeah (with re-binding) |
As you can see from the table, the most complete and safe method is to use an official application, which ensures that data is synchronized before the connection is broken and ensures that the device settings are correctly reset, and the rest of the methods should be considered as emergency.
💡
The ideal shutdown scenario is to use the Untie feature inside the app, as it combines data storage and a complete cleanup of the device.
Delete the Mi Account and Linkage
In the Xiaomi ecosystem, there is the concept of linking a device to a Mi Account, which is a security measure that prevents the use of stolen devices. If you plan to sell a watch, it is not enough to untie it from your phone, you need to remove the device from your list of gadgets in your cloud profile.
Go to i.mi.com or your in-app account settings, find Devices or Find Device. From the list, select your watch and click Delete or Unlock, which will remove the activation lock.
- 🔐 This procedure is critical when selling, otherwise the new owner will not be able to customize the watch.
- 🌐 Changes take effect almost immediately after confirmation of the action.
- 📧 The mail may receive a notification about the change of the status of the device in the account.
If you don't delete the device from your account, the new owner will encounter an error when you try to pair, and the system will report that the device is attached to another user, so link control is the final and mandatory step in preparing the gadget for transfer to another person.
Solving and eliminating errors
During the shutdown process, users often face various technical difficulties, such as the Untie button may be inactive, or the process may be suspended while waiting for a response from the device, most often due to an unstable Bluetooth connection.
Try to get closer to the clock to eliminate interference. Also helps is rebooting the Bluetooth module on your phone: turn it off and turn it on again. In rare cases, you need to reboot the smartphone itself to clear the cache of Bluetooth services.
⚠️ Warning: If the watch doesn't respond to any commands and doesn't show up in Bluetooth search, it may be completely discharged. 15-20 minutes, even if the indicator does not immediately light up.
If nothing helps, you can try to find the device through third-party Bluetooth utilities like nRF Connect and try to break the connection at the level. GATT-It's a method for advanced users, but in most cases, it's enough to just wait until the watch comes in range, or to do a hard reset with a button on the case (if the model allows you to do it).
