I got the update this week for 3.1 but I just got the 20 last week, so with the latest update we can't tell it to change to which type of power saving mode or am I just stupid and can't find it now? I find how to put it in power saving but couldn't specify a mode. Since the update my batt life is terrible. I will not even use the phone and hours later I'm down 50% with apps disabled and put to sleep UGH!!
