I actually went so far as to buy a new 5S a couple of weeks ago after I got drunk and threw my old one at the ground one too many times and smashed it to pieces. It was due for replacement anyway because the battery was hosed and losing charge way too fast. I could've paid a bit more for the 6 or 6s and I love the shape and construction of the phone, but the size is simply a dealbreaker for me.
I know this isn't the question you asked and you've already moved on, but for others, there is a way around this problem on the iPhone. If you 'soft tap' the home button twice, the entire display shifts down about 3 inches.
I think he already know that, and I kind of agree.
Sure, some people can multi-task. I might even be one of them. But I prefer not to.
This would appear to be reasonably dependent on the size of the person. The idea that a smaller person and an NBA player would like the same size is a bit silly, no?
Hopefully there will be a future update at the smaller size.
I know on the 6 you can double tap the home key to bring the screen down, but that is a bandaid. I also found the double tap unresponsive sometimes, often having to try two or three times, in which time I could have just repositioned my hand.
To me, the 5 is near the optimal smartphone size.
