My Litany for each new WM phone I get

[cornelious2]

as far as performance your right, but it still affect battery life. and the clock does automatically adjust, but it can take several hours for it to do so (talking from experience) I look at it like wearing a seat belt. 99.9999999 percent of the time it does nothing for you, but that once moment you do need it your glad you have it. alot of what I have done may or may not fix a problem/prevent the problem, all I know is it has been a much smoother ride since I have done this.
