Most of my jeans have pretty small pockets (biggest thing I've noticed with higher end denim is the pockets are much smaller than levis, etc). An iPhone 5 sized device is about the max that will fit in there, a 6 (4.7 inches) borders on too large. But those pockets are plenty large for a phone, keys, wallet in my back pocket, and a few other small items. There's a difference between "useless pockets you can't carry anything around in" and useful pockets you can't carry a tablet-sized device in.

So yeah, it's definitely an issue for both sexes. You may not buy pants that don't have large enough pockets, but I won't base my wardrobe around my phone and won't buy a phone that I can't easily fit in average sized pockets.

I always associated massive phones as being marketed towards women seeing as, at least in western culture, they're generally the demographic that is able to conveniently carry them. Most men don't have the pocket space to carry a 6 inch phone, and I've heard a lot of complaints around the new iPhone screen size (the smaller, not the 6-plus) from both genders as being too large to conveniently carry.
