Hi there, I have a Early 2011 MBP 2.2 Ghz i7 with the 6750 AMD GPU. However, I find it to suck too much battery and I never need it so I use gfxCardStatus to turn it off while on the road. MacOS does a horrible job deciding which GPU to use, even skype triggers the change. So... When I come home, I switch to discrete GPU only and when I leave home again, I'll set it to integrated. However, I found when I was using my Mac at home for a while and change the GPU from discrete to integrated, the battery life will stay at 3-4 hours in idle, so it didn't really switch gpus. The only thing that helps here is a restart, which is SUPER annoying. Anyone else found a better solution for my problem?
