Smartphones with Bluetooth v6.1

v6.1

— the main difference in Bluetooth 6.1 is not about a significant increase in speed or sound quality, but rather the improvement in privacy and energy efficiency: the device can change its Bluetooth address less predictably, making it harder to track via wireless signal.

Compared to Bluetooth 5.x and 6.0, this version is more like a security and background operation enhancement rather than a completely new use scenario. Meanwhile, a smartphone with Bluetooth 6.1 typically maintains compatibility with older accessories, but new features work only where both devices support them.
