So, I just purchased an early 2011 MBP. I know, I know, refresh is coming, but my previous laptop died and I needed this for school. Also, I got the 2.2GHz 15" on sale and didn't have to pay any sales tax, so I saved some more money. Anyways, I have a question about the battery life. The machine came with Lion and I have upgraded it to 10.7.3. I have also installed gfxCardStatus and put it into integrated only mode. My battery life seems to be much lower than it should be, although I'm not sure if the battery just needs to be used a bit for it to calibrate itself. For example, I'm at 87% battery life and it estimates 2 hours remaining (though it jumps down to 1 hour 30 minutes remaining and back up again every few minutes). I am downloading a large file over wifi, bluetooth is turned off, and screen brightness is at 30-40%. My question is: Does the battery need to be "broken in" to be calibrated? Or is it possible that something needs to be fixed? I have read that some people reset their SMC and it cleared up issues, though it seems like with a machine that hasn't been out of it's box for 24 hours yet, that shouldn't be necessary. Perhaps there's something I can adjust to increase battery life? In linux/windows, I could have the processor automatically down clock itself to improve battery life on my old netbook, that's probably already happening but I'm not sure where to check. This is my first mac and so far it's been a nice experience, I'd just like to figure out how to get closer to the 7 hours advertised battery life.
