This is how its for me, got the 6+ and then the 6s+, but towards May of this year I started getting tired of the plus size of the phone. So I sold that and got myself the 6s 128GB. And I was very happy with the shift in size, totally loved the one handed use, portability but wasn't happy with the battery life although it wasn't much of a deal breaker since I had chargers everywhere (work, car, home,etc).
Then came the 7 and i was torn between the 2 sizes again as the 7+ had a better camera, etc. So preordered the 7+ Black 256 GB, got the delivery and here I am thinking of going back to the smaller size after using the plus for over a week. I don't know but its just the ease of use, smaller footprint, etc is what is pulling me towards it.
I'm kinda glad that I'm not the only one in this. ��
