Well, the independent tests state that I can web browse for 9 hours. I can actually do a good hour longer than that but hey. They also state that the S6 can be used to browse the web for almost 11 hours, so does that involve not having the screen on for half that time? How does that work then?

I'm a rescue officer. Most of my working day is spent sat on my butt and yes, I regularly browse and play videos for 8-10 hours non-stop. Sure I stop for toilet & drinks breaks etc but I'm never off this thing. I charge my 6+ every single day and I drain it to 1% every single day. I never listen to music, the screen is on all the time.
