How to pair a watch/band with a new phone?

There are two methods to rebind the device to a new phone, as described below:
1. Perform a factory reset on the device, then use the new phone to bind it again;
2. While the device is connected to the original phone, unbind it in the Mi Fitness APP. After unbinding, use the new phone to bind the device.
Note:
1. Some older devices allow you to switch phones without unbinding, as long as you log into the same Xiaomi Account in the Mi Fitness APP on the new phone. Once logged in, restore the connection. After successful login and connection, your data will sync. (The original phone must have its Bluetooth disconnected, or else the new phone won’t be able to connect);
2. New devices support the option to connect a new phone directly from the device under [Settings] >> [System] (you’ll see the Connect new phone option). After selecting this, simply open the Mi Fitness APP on the new phone, tap [Add device], and follow the instructions to complete the binding. (If using the same Xiaomi Account, no need to factory reset. However, if using a new Xiaomi Account, the device will prompt for a factory reset.)
