I received my iPhone 6 Plus 64GB spacegray at about 3pm on Friday and set it up, but haven't worn it out that day, so it wasn't in my pocket. Yesterday, I left at 10am with the iPhone in my left FRONT pocket of my suit pants. I drove 4 hours to a wedding, which also involved a lot of sitting during dinner etc but also 2-3 hours of dancing. I left at 2am and went to bed, driving home 4 hours back. So in total, the 6 Plus was about 18 hours in my pocket while sitting mostly. As I lay it on the coffee table and sat down on the couch to relax from the drive (yes, sitting again ), I saw the reflection of the window in the iPhones slightly distorted. Now I lay it flat with the display side on the table, take a look. Maybe at 5.5" it is too thin?
