Bluetooth for Xiaomi watches and Bluetooth for mobile phones are two different concepts. Bluetooth is a wireless communication technology used to transfer data over short distances between devices. Both the Xiaomi watch and the phone support Bluetooth technology, but the distance between them is not measured in meters. The transmission distance of Bluetooth is usually about 10 meters, but the actual distance may be different depending on the environment and device performance. Therefore, it is not possible to accurately answer the specific distance between Xiaomi watch Bluetooth and mobile phone Bluetooth.
