There have been numerous reports, including our own anecdotal ones, about how much better Safari is than Chrome when it comes to battery life on MacBooks. Here's another on, this time from Battery Box:

Averaging data from all websites tested, Safari won first place with 6 hours 21 minutes of total usage, Firefox second with 5 hours 29 minutes of usage, and Chrome last with 5 hours 8 minutes of usage.

Basically, if you simply switch to using Safari instead of Chrome, on average you could get an extra 1 hour of usage from your battery life.

Not innovating anymore, WebKit's ass.
