Here's a crazy new rumor for the Samsung Galaxy S7. Supposedly it will be able to play 17 straight hours of video at max display brightness. Of course, we are highly skeptical of this claim, as this would be unheard battery life from a 3,000 mAh battery (which is what the Galaxy S7 is rumored to have).
We believe it is possible to see a notable improvement from software and hardware optimizations as well as the increased efficiency that will be gained from Samsung's 2nd-gen 14nm FinFET process, but this rumor would be over 3 times more efficient than the Galaxy S6. It seems unlikely that Samsung could pull off something so astounding.
It would be pretty awesome if we were wrong!
