Pretty good battery life! Are you saying it's weird that you're getting this much? Were you primarily watching YouTube? If you just do one activity the whole time, the battery life tends to be better, because you're not expending more energy opening and closing apps. That's how the battery life tests that reviewers use yield such good numbers -- they're just turning on a video nonstop and leaving the phone alone until it runs out of battery, which is not exactly real-world usage.
