I have, in fact, gone the other way... I had installed the 10.3 preview shortly after it's announcement, and my battery life instantly went from 4+ hours per charge to roughly 2-2 1/4 hours. I've reset all manner of settings I can think of, but nothing has brought that count back up. I've since re-installed 10.2.6, but have seen no change... any ideas? aa
