So I checked that and there where several system compenants that where near the same amount of usage as the screen itself. I don't remember what those where last time I had the issue but I think it was android system and cell standby but im not sure. I did not have this problem today and looking at the graph it was all low draw except little blurps which I would guess is the phone checking weather, facebook, and stuff like that. No phantom 400 ma draws. The thing is that today I spent most of the day in a 3g area where it would not be on the 4g network at all. Could it have something to do with that? I don't want to end up like sprint people who have to turn the 4g off and on. I feel that really ruins the 4g experience and the HTC rep said that it wasn't going to be that way with this phone.
