Ars Technica reviewed iOS 7, and after benchmarking the battery life of iOS 7 compared to iOS 6 they came to the conclusion that iOS 7 drains the battery faster than iOS 6: The Dutch site Tweakers.net came to the same conclusion after thoroughly testing the battery life of iOS 7. Seems to me there is work to be done by Apple. I'm aware that a lot of you are probably experiencing better batttery life, but one person's data is not a useful statistic. Unless anyone can counterclaim these findings with objective benchmarking tools, the consensus currently is that iOS 7 will take a bite out of your battery life. Yours truly.
