: Unplug usb cable?

After you hook your iPhone up to the USB plug and audio jack in the center console, listen to music and arrive at your destination, if you take your phone with you, should you unplug the USB cable? Although it is then not plugged into a player, does it still drain the battery if the cable is left plugged in at the armrest console?

No, I never unplug mine. I don't believe it draws any power if it's not connected to a device on the other end.

No, the circuit is open without the phone hooked up, so no power drain. Mine has been left plugged in since day one. My car is a weekend only ride, and it often is not driven for several weeks at a time. Never had a problem...
