I have the same question -- I turned off the Bluetooth radio on my phone the day I got it, and I've never turned it back on. But does that mean the radio is actually powered down, or is the phone blocking Bluetooth at a higher level? Similarly, or possibly the same question, is an rfkill soft block adequate for a laptop with bluetooth?

On a laptop, if you want to be sure, you can at least do `sudo modprobe -r btusb` (or whatever your particular chipset's BT driver is called).

A very good point -- that's definitely better than rfkill.
