I was able to take a quick look at BetterBatteryStats and the top two items on the partial wakelock list were the Nielsen mobile panel app and one of the Google NLP services, so I'm guessing that the phone was hunting for a data signal the whole time, and that was what was causing the battery drain.
Can anyone recommend an app that will disable data and/or wifi if no good signal is available, and perhaps re-check every 15 minutes? I remember reading about just such an app in the last couple of weeks, but can't remember what it was called and haven't had any luck googling it.
I guess, tasker can do that
