So my battery results haven't been accurate enough to post on here for the past couple days, as I have been doing a lot of music transferring over USB since then (about 6GB worth thanks to friends telling me about different bands...) so there are places where there's a charge spike. But, even though I have done that, I have noticed that my battery life is far superior to my S3. I listened to music on the bus with bass boost EQ, while texting a friend through hangouts. I'm a little over halfway through the school day, I haven't plugged the phone in at all, and I have 85% left.
