Wondering about the high android system?

15 hours with 23% battery drain is simply awesome. Nothing to worry about...all normal.

Seems normal. There is a bug that pops up where Google play services will drain your battery but that is not the case with your screen shot.

If I'm not really using my phone much my screen looks pretty much just like yours. Sometimes my screen is the third item.
