This is a discussion thread for the "Mac OS X 10.8.2 Improves Battery Life on Mountain Lion" story posted on the front page.
Good news! I was a little worried about the battery life... Uh...why are the HDD's getting better battery life than the SSDs???
Does this apply to the Macbook Air as well? I tested how long my Air would run yesterday (got it Friday) and I got easily to the seven hours Apple promises and above. So with 10.8.2 I get even better battery life?
My guess is HDD's don't use up a noticeable amount of power versus SSD's and we were lied to by people who said "no moving parts = better battery life"
