I just noticed my phone was warm and battery much lower than it should be at this point in the day. Over in the battery screen, I see something peculiar. The Messages app shows 1.1 hours of background usage in the last 6 days, but an entire hour of that was just in the last 24 hours. Meanwhile, on-screen usage is about the same day-to-day. The app was used in the foreground for 20 minutes in the last 24 hours and yet drained more battery than 1.5 hours of Safari. That's alarming. I restarted the phone, and it is now back to a cool temperature. This sort of flaky background draining isn't something you want to see in a core app like Messages. Is anyone else seeing something like this? EDIT: To be clear, I've had the GM running since its release last week, so this isn't a case of Messages doing some initial indexing or analysis.
