I think some people are seeing it, and it might be in relation to some people using various new features in the Messages app, using various new Messages apps and the store for them, perhaps having a lot of saved messages and attachments that might be getting indexed, or something else of that nature, given that it's been just over a day since the update came out.I'm concerned about the battery life with the Messages app in particular, specifically the drain a lot of folks are noticing when the app runs in the background. I'd expect drain from a crappy coded app like Facebook but not a staple, built-in iOS app like Messages.
What about security?
