Still debating on the size of the Xs. I plan to get the either the standard or MAX size. However, it seems like this years sizes don't differentiate much. UI optimization isn't special on the MAX. The only difference that came across my research is the battery life and slightly higher resolution. Heck, even the PPI is the same for both phones. I've always preferred the larger phones since the inception of the 6 due to battery size. Apart from the size. Can someone explain why you would go for the bigger size? I plan to upgrade from a 7+ after the Xr comes out. I've played around with both Xs and Xs MAX, but seems like the MAX size feels like a larger phone compared to 6, 7, 8 and their + size counterparts.
