Read alot and am still very confuse. Have a one month old mbp, built in nov 2010; however my battery is only lasting about 3 hours... Before I calibrate is that the best opinion?? What else can be going on...

I also use it most of the time on battery power until I am forced to plug in.. I think I have actually only had 4-5 actual charging cycles.... 3-4 hours is far from 8-10 hours...

What do you mean by this?

Also: I'm on one made in October and I can easily get 8 hours. But that's not always with the brightness all the way up.

So that's it, just perform the calibration?? Outside of screen brightness, is there anything else I can check or adjust

No. Just do the calibration first before you judge how well it's fairing.

Well what are you running on your Mac? Check Activity Monitor to see if the apps you're running are CPU intensive. Are you watching videos? Editing videos/photos/etc?

Those things combined with screen brightness can severely cut down battery life.
