Facebook is one of the worst battery apps ever made. Uninstalling that will have a huge impact.
I know Facebook doesn't help the battery, but there is something else going on here. Here are my stats from today, about 10 hours on battery with less than one hour of screen on time and streaming music for a couple hours. I did uninstall Facebook this morning just to show it isn't the culprit. I had twitter open for less than 5 minutes, yet it somehow continues to eat up battery, just like Facebook did before. That's what makes me think there is something to the mobile radio active bug. And I didn't even open I Heart Radio, so not sure how that ended up using battery.
