I have a 15-inch MBP, Mid-2010, 2.66GHz i7, with Intel integrated graphics and a discrete NVIDIA GeForce GT 330M. Since I installed Lion, it seems my battery life has gone down to just 2 or 3 hours. After reading various things on the internet, I found out about the gfxCardStatus app which I used and noticed my machine is using the discrete graphics card. It appears the following apps are requiring discrete graphics:
- the Google Talk plugin (because I keep gmail.com open, even though I'm not signed in to chat)
- Twitter for Mac
- both Droplr and CloudApp
Should I be concerned about these? Will it affect my battery life if my machine switches to discrete graphics even though these apps may not actively be using it?
And, as a follow-up: is resetting the SMC (another thing I read people have been trying) a good thing to try to improve my battery life?
