MoF'n Safari is sucking battery like chrome off a trailer hitch! I was noticing this especially on MacRumors site, since I have had a tab open for it since I got this awesome MBP. I just installed the Ghostery extension and it saved me around 2.5-3 watts consumption on the Macrumors site (equates to a couple hours of battery life). I highly recommend it. I am not in any way affiliated with Ghostery, nor do I understand how exactly it is saving power. But I did surmise that ads, tracking, and other trash are drawing power. This varies from site to site. Like everything else on the new MBP, there is big variability of power consumption with these new chips. Just thought I'd pass along the tip for those with Safari specific power issues. If you have general power issues, that other thread has your solutions.
