On the theory that iPhone demand is getting lower, I'd have to agree. I used to upgrade every 2 years because there was some cool feature or battery life improvement I wanted, but my 6S is definitely going to be sticking around until the next announce (so 3 years now). I really can't see why my parents would upgrade their phones in the next 5 years unless their batteries stop working. Whats driving new phone sales nowadays? Games and apps have sort of plateaued (though lucrative for some), streaming services are pretty much matured and are going to work on any current device for a while. I can't think of what the "next" thing is going to be. I felt that health was their best shot, but it seems like the tech just isn't there to give exceptionally useful data, plus you probably need a watch. The only thing I can think of that keeps it going with non-tech is the status symbol aspect. Resolution is past the point of really mattering. Battery life could be improved, but its finally alright. Bezels? Who really cares about a few MM of screen space, except for those who want to signal they paid $1000 for a phone?
