I realize this might be an annoying topic for you guys to post on but I was curious about something. I was thinking for those of you that upgraded from a MBP 2011 15" to a MBP 2012 15" with a Hi-Res Display how does the battery life compare? I know the pro's of the 2012 MBP has Ivy bridge w/ lower power consumption and the integrated Intel 4000 and the Discrete NVIDIA Graphics card both also has lower power consumption (and better performance) but the Hi-Res display would naturally negatively affect the battery life. Does anyone have a ballpark estimation of how much either way (plus/minus)? Thanks in advance.
