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.
Here is a video showing how easy it is to get an iPhone 6+ bent.
