I haven't really noticed much of a change in the features that I use since the update so its been normal phone use since the update. Normal days are normal days, no change in battery life. However, my low-signal school days are landing me with a flashing red light before my last class when I used to not hit that until I got home.
Not that I really care, I don't use the phone for anything between 3PM and 9PM. Just check to see if I've got any email or texts. It just sits there dying on its own, all lonely and sad.
