How is your iOS 5.1.1 battery life? [Poll]

Apple released iOS 5.1.1 a couple of days ago, and it included numerous bug fixes and performance improvements, so I have to ask -- how's your battery life? How's your performance? If you were having issues before, did iOS 5.1.1 fix any of them? Did it introduce any new ones? Battery life can be tricky. There are background tasks, push services, location services and features that make our lives better or more interesting and yet put a constant strain on our battery. There are apps that do fantastic things but for some reason can't be kept active or they drain power while we're watching.
