How to untie Xiaomi Mi Band 4 without a phone: the complete guide

Owning Xiaomi wearables often involves changing a device or transferring a gadget to another user, a situation where an old smartphone is lost, broken or simply unavailable, and the Mi Band 4 bracelet must be untieable, is quite common. Many users mistakenly believe that without access to the Mi Fit or Zepp Life app on the original device, this operation cannot be performed.

But the architecture of synchronizing data and device binding is designed to physically access the activity tracker itself, which is critical for anyone planning to sell a gadget or just wanting to start using it from scratch. In this article, we’ll go through all the available methods, including software and hardware resets.

It's worth noting that the untie procedure without a phone actually means a complete reset of the device to factory status, which will delete all the accumulated training and activity data stored in the wristband's memory, but will not affect the history in the cloud if the synchronization was done before, and understanding this process will help avoid panic and loss of important health data.

Why there is a need to detach the device

The main reason why users are looking for a way to untie the Mi Band 4 from an account without a phone is to change the owner of the gadget. When selling or donating the device, the new owner will not be able to connect it to his smartphone unless the old binding is removed. Xiaomi security system blocks the re-registration of the device on another account until the connection with the previous one is broken.

Another common situation is the loss or breakdown of the main smartphone. If the phone is lost and the Mi Account or Zepp Life profile remains active with the attached device, this can create conflicts when trying to connect a new tracker or restore data.

It's important to understand the difference between an in-app unduction and a hardware reset. If the phone is on hand but the app is removed, you just need to reinstall the software. But if you don't have access to the phone at all, you have to rely on the bracelet's features or the web-based account management interfaces.

• 🔄 Change of device owner requires removal of old tether.
• 📱 Loss or breakage of a smartphone makes the standard method through the application inaccessible.
• 🐛 Synchronization software failures often require a complete device reset.
• 🔒 Account protection prevents unauthorized use of someone else’s gadget.

⚠️ Note: If you plan to sell the bracelet, be sure to follow the unbundling procedure, otherwise the buyer will not be able to use the device.

Hardware resetting settings through the bracelet menu

The most reliable and quick way to untie the Xiaomi Mi Band 4 without a smartphone is to use the built-in menu of the tracker itself. Xiaomi engineers have a full reset feature that returns the device to its original state. This method does not require a Bluetooth connection to the phone at the time of operation.

First, you need to wake up the bracelet screen by touching the touch button or raising your wrist if the function is activated, then swipe the menu left or right until the More item appears, marked with a three-dot icon, and this is where the key settings of the device are hidden.

Inside the More menu, you need to find Settings, which is usually represented by the gear icon. After entering the settings, you should scroll through the list to the bottom, where the Unbind or Reset option is located.

Once confirmed, the bracelet screen will go out and the device will reboot, the Mi Band logo will appear on the screen, indicating the successful completion of the procedure, and now the gadget is ready to find a new smartphone and pair with a new account.

Use the web version of the Mi Cloud account

If access to the physical menu of the bracelet is difficult or the device does not respond to touch, you can try to remove the binding through the web interface of the Xiaomi ecosystem.This method requires that you remember the username and password from the Mi Account account to which the tracker was attached.

You should go to the official i.mi.com website or the device management section at account.xiaomi.com. After authorization, go to the device management section (often called Devices or Devices) and display a list of all the equipment registered to your account.

Find your Mi Band 4 and select the device deletion or detachment option from the list, but it’s worth considering that the web interface doesn’t always have a direct “untie” command for wearables, as they are often managed exclusively through Mi Fit or Zepp Life mobile apps. In such cases, the server reset may not work instantly without synchronization.

However, removing the device from the trusted list in your account security settings can help in some cases, especially if the bracelet is blocking the connection due to an authorization error.

The method of re-binding through a third-party smartphone

The most effective software method, if the bracelet menu is not available, is to use any free smartphone with Android or iOS.The essence of the method is to temporarily install the Mi Fit app (or Zepp Life) and log in to your account, which allows you to remotely manage the bindings, even if your main phone is not at hand.

After installing the application and logging into your profile, go to Profile and select Mi Band 4. From the device menu, find Unbind. The application will send a command to the bracelet (if it is in range) or update the status on the server, breaking the connection. If the bracelet does not connect, you can try adding it as a new device, which sometimes automatically resets the old binding settings.

It is also recommended to immediately remove the application after the operation is completed.

Solving uncoupling problems

Sometimes the detachment process may not go smoothly. The bracelet may freeze, not respond to touch, or display a connection error. In such cases, the first thing you should try to reboot the device by putting it on charge. Connecting to the power source often resuscitates the touch screen and resets temporary software errors.

If the bracelet says "Too many tries" or "Connection error," it may still be trying to sync with the previous phone that's nearby.Make sure the original smartphone has Bluetooth turned off or the Mi Fit app removed.This will prevent automatic reconnection during the reset procedure.

In rare cases, deep discharge helps. Leave the bracelet on until the battery is completely depleted until it turns off itself. Then put it on charge and immediately try to reset through the menu. This method allows you to clear the device's RAM cache.

⚠️ Warning: Do not attempt to open the bracelet body to physically shut off the battery, this will result in loss of tightness and warranty.

What to do after the device is uncoupled

After the successful Unbind procedure, the bracelet returns to the pairing standby mode. QR-A code or logo that suggests you download an app, and now the device is ready to be sold or transferred to a new owner, and if you plan to use it yourself with a new phone, just search the app for the devices.

The new owner should remember that the Mi Band 4 can only be linked to one account at a time. So before buying a used device, always check if it is reset to factory settings. Having someone else's account will make the gadget useless for you.

💡

Tip: Before transferring the bracelet to the new owner, make sure that the screen is displayed QR-Connection code, not your personal profile.

It's also worth noting that once uncoupled, all the steps and sleep data that were not synchronized with the cloud before the reset will be lost irretrievably, so if possible, always try to synchronize before the decoupling procedure.
