Why is my battery performing so badly?

[Hock3y Monk3y29]

I have an S6 Edge, and the battery is awful. I get maybe 10-11 hours if I am lucky with 1-2 hours of screen on time. I am seeing other people get upwards of 15-20 hours with 3-4 hours of screen on time with the s6 edge. I have uploaded some screenshots, please help. (Also, I have tried clearing cache, using an app that automatically turns wifi off every time I lock the phone, so on...) Also, when does android 6.0 come out for S6 Edge? Wondering if that might help at all?

You must be using your phone in direct sunlight, because it looks like the maxed out screen is eating up all your battery. Try turning it down, and try to find some shade.
