It’s 2mm shorter than the 5 IV.

I wouldn’t say so. Not having the 8 Gen 1 is a massive positive in itself and the 8 Gen 2 is actually a good chip. They’ve also upgraded the primary sensor to match the 1 V. Lack of telephoto is a downer but they have made it a little shorter to compensate and they’ve managed to cram the same 5000 mAh battery as last year.
