This whole thing is stupid. I have an iPhone 6 and it just barely fit comfortably in my front pocket. If it's just a bit off I find it awkward and uncomfortable.
I would love to see tests involving the real people who are bending their phones in their pockets. a) to measure the forces in their pockets and b) to see how they can stand that sort of discomfort.
Edit: I'll be specific. When I am standing the phone fits fine in my jeans. It's not great when I try and sit. In some positions it's ok. But in my head I was implying that if it's uncomfortable, I take it out of my pocket. The 6 is definitely the limit of any phone I'd buy.
