In the "what has been using your battery" screen in settings, the usual always show up, display, BT, voice calls, etc. The one thing that never shows up on mine is wifi. Anyone know why? I am still running 2.1 if that makes a difference. If I dial the 4636 number it does show the usage in there. Shouldn't this show in my battery usage screen as well? I have had wifi on for over two hours and it does not show it.
