Hi Russell

You're still using power to power a microwave transmitter via USB though. Probably tethering is better for the laptop battery as Bluetooth is low power rated.

Just a quickie:

If tethering a phone to a macbook, is bluetooth or USB more battery- efficient?

Logic would suggest USB as you are not using power to transmit.

Is that right?

Regards

Russell
