I just wanted to report back that after my first full charge of using iOS7 and it now reporting what my usage is under iOS7, I think I might be getting a little better battery life. It might be too early since this is only my first full charge since updating but I have been using my phone today the same way I normally do everyday and I'm currently at 32% battery left with usage at 5 hrs 25 mins and standby 23 hrs 30 mins. and have not plugged in at all. I figure I can get a couple more hours usage until I get down to 1%. So usually about this time on iOS6 I would be at around 15-20% battery.
Hopefully it will get even better with additional charges.
