I do. I’m not a engineer or anything, so I can’t say definitively, but it seems logical to me. You see the teardowns of these devices, and everything is crammed in incredibly tightly. Every cubic millimetre matters, and the Max is quite a bit bigger.
I’m not sure why Apple needs an ‘excuse’. To excuse what? Selling two slightly different products with different features at different price points? As for why the previous generation didn’t have a size differentiation - I don’t know! It’s a good question, and I have no idea whether it’s a technical or marketing/business thing.
Well, personally, I‘d love that. As a battery case user, I’d be very excited about a proper chunky phone with an exponentially larger battery life, especially if they extra space was used to improve the camera. But geeks like me on forums like this have been calling for a phone like that for many years. The people who actually build and sell these things have clearly decided that we’re a small but vocal minority.
