I don't see anything wrong with the battery usage, wait until it goes down to 50% and take that same screenshot, also 

tap on the top 5 items on the list and take screenshots, post them all here. 

And one more screenshot

settings > about phone > status > signal strength.

There's nothing wrong with your phone, the screen was on for 3hrs and 30mins

Is that normal ?
