I really don't pay attention to screen on time, but my S7 easily gets me through a day even under the most demanding conditions. It has been the best phone I have ever owned in this regard. It has passed a test no other phone of mine ever could pass: A day @ Disneyland. Unplugged phone around 11:30am, streamed music all the way there (and back...one hour), spent 10 hours there taking many photos and video (testing the camera out), got home about 10:30pm and still had 55% battery. I didn't even need the power brick I brought with me. This was with Bluetooth and wifi left on the entire day too. With all my old phones I was running around looking for a charge in situations like that. They never survived a full day at at a theme park, ever. The S7 has been the first phone I have felt that I could actually USE, and not have to baby. Love it.
