Rather late to this thread. I must say that gfxCardStatus is excellent, useful way beyond Xcode. For me, by the way, Xcode itself doesn't cause the switch away from the integrated chipset, but the iOS simulator does.
Anyone who cares about battery life (or a machine hot on the knees), I really suggest downloading this tiny utility. It's changed how I use my machine. e.g. now I only use Firefox if I really have to as it switches on the graphics card just by running, other programs I close down when I'm done with them because again, just having them up causes a graphics card switch. I've also noticed no real performance hit from forcing the machine into integrated graphics mode either, which is now my 'on battery' setting.
