Guys, it definitely sounds like you have battery issues. Mine has been epic and continues to be so even now a month later. I'm currently sitting on 2 days 21 hours on one charge and still have 37% battery left. I've sent over 60 text messages over the last two days too, and not all on wifi either.
If you aren't even getting a quarter of that then I would take it back and see if you can exchange it.
