I've had a search and due to too many common terms cannot find answer. I want my bluetooth only to be switch on when it is connected to a charger, is there a setting somewhere that allows this? One of my old motorola phone used to have profile config for charging, or silent, etc. I cant see anything like this on the iPhone. I want the bluetooth to be active when I plug the phone into the car charger so that it then links to the car phone system, then turn off bluetooth when unplugged. It's so easy to forget to turn off bluetooth and the battery runs out before you realise it's been left on.
