The 6s Plus is good for women who carry purses or men who have enormous pockets like male clowns, Karate instructors, parachutists, and fly fisherman.
For everyone else the 6s is the sane choice. The battery life increase is marginal and so is the image quality increase, OIS is essentially irrelevant if you have steady hands. The large size is useless to anybody with an ipad.
Um, it fits in the front pocket of Levi jean. It has fit in all my pant pockets so far without issue. I'm 5'10"
I have 14 hours standby and 6 hours 52 minutes use and 27% left right now. Sorry but your info isn't accurate.
