Wearables users often face a situation where they need to disconnect the fitness tracker from their account, but access to the old smartphone is no longer available. This can happen when selling the device, breaking the main gadget, or simply losing access to the account. Owners of the Xiaomi Mi Band 4 model wonder whether it is possible to perform this procedure without having a phone that was previously paired with them.
The answer to this question is ambiguous and depends on what you mean by “untie.” Completely removing a device from your Mi Account or Google Fit cloud profile without logging in via the Mi Fit app (now Zepp Life) is technically impossible because of the security architecture. However, if your goal is to break your current Bluetooth connection or prepare a tracker for sale, there are effective methods that do not require a smartphone.
In this article, we will take a look at all the ways you can reset and disconnect, how to force the connection to be broken, how to clear the data on the device itself, and what to do if your old phone is lost forever, and it is important to understand the difference between simply disconnecting and completely deleting your account.
Technical limitations of the detachment without a smartphone
The interface architecture of Xiaomi Mi Band 4 and mobile devices is built in such a way that the bracelet is a dependent peripheral device. SIM-All authorization and deauthorization commands are transmitted via Bluetooth connection from the intermediary application.
When you try to unplug a device, Xiaomi servers need to get confirmation that the account owner actually initiated this action.Without logging into the application on an authorized device, it is impossible to send such a signal directly from the bracelet.This is done to protect user data so that an attacker cannot delete the tracker from the victim's account just by being nearby.
⚠️ Warning: There are no hidden buttons or secret tap combinations on the Mi Band 4 itself that would remove the device from the cloud profile without being confirmed through the app.
However, a physical reset of the bracelet settings is possible, which will put the gadget back out of the box by clearing all the stored data about the pulse, steps and dreams stored in the device's memory, but the binding to the server-side account will remain active until logged in from any other phone.

Direct deletion from the account without the application is impossible, but a full reset of data on the device is available to everyone.

Method of complete reset through the bracelet menu
The most reliable way to untie a device, if that means clearing it of personal data and preparing for a new pairing, is to perform a reset, which completely erases all the information stored in the Mi Band 4 memory and breaks the current active Bluetooth connection.
You don't need a phone to do this. All the actions are done directly through the tracker's touch interface. First, you wake the screen by touching it or lifting your wrist. Then you look for the "More" icon (usually looking like three dots or horizontal bars at the end of the list) and scroll through the menu to Settings.
Inside the settings menu, you need to find the Reset or Unbind option. Clicking on this button will cause a confirmation request, as the system warns you of data loss. Once confirmed, the device will restart, and all settings will be returned to factory values.
- 🔄 Find the “More” menu icon on the tracker’s home screen.
- ⚙️ Go to Settings and select Reset.
- ✅ Confirm the action by pressing the touch area to start the process.
Once the procedure is complete, the bracelet will go into pairing standby mode. QR-Mi Band code or logo signaling readiness to connect to a new smartphone, old pedometer and pulse data will be deleted irrevocably.
☑️ Pre-reset check
Using the “Find Device” function to break the connection
There is a lesser-known method that allows you to forcibly break the connection if the bracelet is still trying to sync with the lost phone. Although this feature is more often used to find a gadget, it can help in a situation where you need to “scare” the bracelet from an old device.
If you have access to a computer or tablet, you can try logging into the web version of the Xiaomi Cloud service. However, the functionality of the web interface for wearable devices is extremely limited. It allows you to see the status of the device, but rarely gives a command to uncoup. However, it is worth checking the Devices section in the Mi Account profile.
Ignoring is a more effective method, and if you just stop wearing the bracelet next to your old phone, it'll go into power-saving mode and stop trying to connect, but it's not a good way to decouple your account completely. It just stops the data transfer in real time.
| Action. | Impact on data | The need for a telephone | The result |
|---|---|---|---|
| Reset via menu | Complete removal | Not required | Ready for a new sale |
| Turning off Bluetooth | Data is retained | Required. | Time gap |
| Removal from Mi Cloud | Cleaning the cloud | Entry required | Account untied |
It is important to note that none of the software methods will replace a physical reset if the phone is lost.Mi Band 4 has no remote control over the Internet, since the device does not have its own device. IP-address.
Working with Mi Account through the browser
If your goal is to remove the device from the trusted list in your Mi Account profile so that the new owner doesn’t see your data, you’ll have to use any available device with Internet access.
You need to go to the official i.mi.com website and log in with your login and password. In the Devices section, you can see a list of all the gadgets associated with your account. There is often an option to delete the device or change the password, which indirectly affects access.
Changing your account password is a radical but effective step. If you change the password from Mi Account, any device trying to sync using old authorization tokens will require re-entering data. This effectively untethers the bracelet until it is reconnected with the new password.
What happens to the data after changing the password?
After performing the actions in the browser, it is also recommended to check the Security section and delete old sessions.This ensures that no one can access your profile and re-associate the tracker without your knowledge.
Nuances of sales and transfer of the bracelet
When selling the Xiaomi Mi Band 4 to a new owner, it is critical not only to reset the settings, but also to make sure that the device is not locked by binding to your account. Unlike smartphones, trackers rarely have a hard activation lock, but there can be conflicts when trying to pair.
The new owner, when trying to connect the bracelet, may see a message that the device is already occupied or tied to another account.In most cases, Zepp Life (formerly Mi Fit) allows you to force the device to be unplugged on the first connection attempt if the previous owner has performed a reset.
- 🧹 Make sure to complete a full reset before transfer.
- 🔓 Make sure the bracelet doesn’t show up in your app as an active device.
- 📦 Transmit the device in a discharged state or with a charge near 50-60%.
If you just reset the settings but don’t remove the device from your app (because there’s no phone), the new user will still be able to use it. They’ll just link it to their account, and your steps history will stay in the cloud and a new one will start on the wristband.
⚠️ Note: When selling a device, make sure you don’t share your health data with it if it’s synchronized with other health services.
Frequent problems and their solutions
During the detachment process, users may encounter various errors, such as the bracelet may not respond to touch when trying to reset, in which case you need to connect the device to the charger, often low battery power blocks the execution of energy-intensive operations, such as cleaning memory.
Another common problem is that the bracelet will freeze in pairing mode after resetting. If the screen is on or the device is not responding, try putting it on charge for 15-20 minutes, which will restart the power controller and can solve the problem of software failure.
If the bracelet appears as "Unknown Device" in the phone's Bluetooth settings when you try to check, it's normal after resetting.The main thing is that in the Zepp Life or Mi Fit app itself, it's not active on any phone.

If the bracelet is not reset through the menu, put it on charge - this often solves the problem of the interface freeze.
