really? Like I said, I don't use either app, so I don't know what it should look like, but in my experience, apps don't usually operate that long in the background. You must be getting a lot of notifications or something.
Did you check what apps are running in the background like I suggested in my first post? Maybe there's something there that's the real culprit. I've had crazy battery drain a couple of times and the battery stats page was completely useless. It didn't list the actual app that had drained my battery so much, but it was one that was running in the background.
And, like I also said in the first post, it might take some trial and error to figure out what is draining you battery. Maybe since Facebook is running in the background so much, maybe try disabling Facebook for a few hours and use Facebook on another device for a while to see if the graph shows signs of evening out.
