I was finally jumping from iPhone 7+ that was getting long on the teeth after nearly 4 years of use, looking for sufficiently large screen in as small body as possible. After looking closely at various iPhone 11 and 12 models, I realized that anything smaller than Max has screen narrower than 7+, and that wouldn't work too well for my eyes. 12 didn't seem to have enough advantages over 11 for me, when considering pricing difference, so I went with used 11 Pro Max and that was the right choice. Same screen width, but much longer, much better picture/text quality and sound, camera, better signal sensitivity. When placed into Otter case, it's actually a tad smaller than 7+, although noticeably heavier. Battery life is simply outstanding: after my usual day use it still has 50% to 80% left, when my old 7+ was 30% or lower even with replacement battery. Great phone.
