Overall, nothing looks out of place to me. It's usually helpful to post the stats from the display section with any battery troubleshooting too, but I don't think it's necessary in this case. Often the android system will be a high percentage if most of the time you are just scrolling through menu's settings, ect. My phone usually does have much better battery life than that, but recently when I updated to Jelly Bean on this thing, mine's been having a little worse battery life too. I think for now your phone looks fine, let it go a few days and if you still have issues with it, post again on here, but nothing is standing out for now. Just as a comparison, on days when I don't use my phone much at all (A few texts throughout the day, maybe checking some news articles for a few minutes throughout the day, and less than an hour of talk time) I can end a 16-hour day with 75-80 percent battery left. That is with LIGHT use, often I do use it more than that too.
