Personally i never managed to adjust to 6,6s and 7 plus size during summer. Never had any issues with its weight. Now with iPhone X after so many months i still can’t get used to its weight.....it’s very cumbersome to hold it. You feel like it’s dragging you down. So for me size is a less of an issue when compared to x’s weight or weight balance.....I hate it.
I think you mean you never adjusted to the ‘5.5 iPhone Plus’. But I see your point, The trade off having these larger phones with bigger displays, is there not convenient to always carry around in your pocket. I would much prefer a smaller iPhone with an OLED display, but that’s the options Apple provided us with the sizes of the Plus or 5.8/6.5 X.
