Re: [apple-iphone] 4S Bluetooth Question Please

 

My guess is that the same applies as for 3G: it uses power even if you're
not using the connection, because it's continuously broadcasting a signal
*and* looking for possible connections. The power used is less than for 3G
but I doubt that it's insignificant.
