I got an iPhone 4 on launch day and have noticed something fishy with my standby and usage times. For example, today I took it off the charger at about half 8, went to work, haven't used it much at all. It says it's been on standby for 8 hours 40 minutes, and in use for 7 hours 15. I checked it throughout the day and it appeared to be steadily increasing. I reset my settings which looked like it fixed it for a while. But it's back to steadily increasing. Anyone have any similar issues? Ps. I didn't restore from a backup, I have 2 exchange accounts that were set to push but are now every 30 minutes.
