I agree with you on your heavier statement. I was first surprised when I lifted its box out of the shipping box. Although the box is smaller than the box my 11 Pro Max came in it seemed to be noticeably heavier. The phone does also even though I used my 11PM with the Apple Smart Battery case. I really love it.Solid is the word, it feels like a solid chunk of metal.
By far the most well built phone Apple have ever released.
I’m coming from a 11PM and it is noticeably heavier, but I’ve not really noticed a difference in physical size. It doesn’t “feel” bigger to me, but it does look chunkier.
Love it and so pleased I upgraded. They are gorgeous in the flesh.
