I followed the tips from another thread but the battery life was still garbage. Had to turn off Cellular Data when I had WiFi to make it acceptable. On an iPhone 4S after a clean install.

That is one epic battery life man!
After all, iOS 7 is still in beta. There are bound to be battery bugs here & there. As long as the battery is not that bad, I think you guys should put up with it. Shouldn't you guys be expecting battery flaws when installing a beta software?
