My battery issue was mostly due to the email app. That seems to have settled down after a few force stops, and now I'm back to about normal. Unplugged for 16 hours and still at 62% battery left. There's stuff I still don't like much, but it's not that it's better or worse, just different. By the time the next update comes out I'll have adjusted and got used to this one, and will have to go through the whole process again. The only thing I really don't like is the calendar, I think they made it more cumbersome to use for no real reason.
