The title thing is funny, if you look at the URL it's a more accurate title.

Title aside, very interesting article I'd like to see what factors play into these huge disparities of battery life loss between the different browsers.

I suppose that just displaying a page and scrolling around it consumes little energy, with a short spike during the layout phase.

What really consumes energy is compiling and executing Javascript, and playing animations (flash, gif, css, video). JS engines of all three browsers are likely different. I also suspect that Safari, being essentially single-platform, can afford platform-specific optimizations (e.g cheaper non-public API calls).
