I decided to swap it at the Apple Store for the 11 Pro Max, and immediately decided that was my final decision. The battery life on this thing is INSANE, lasting longer than my XS Max ever did, as well as my 11 Pro (understandably). One-handed use is still easy for me (although the 11 Pro is obviously better at that), and the screen real estate
The battery life of each device is also quite different; the iPhone 13 Pro Max has an upgraded battery of 4352 mAh, in comparison to the 3174 mAh battery on the XS Max, which is quite a jump for extended web browsing or video streaming. The display size and resolution are also different between these two models; while both have 6-inch displays

The iPhone 11 Pro and iPhone XS displays are pretty similar across both standard models and larger Max models. The iPhone 11 Pro has the same size 5.8-inch Super Retina OLED display as the iPhone XS, and the iPhone 11 Pro Max has the same size 6.5-inch Super Retina OLED display as the iPhone XS Max. However, there are two key differences.

The XS Max has a 6.5” screen and the 12 Pro Max has a 6.7” screen. While the sizes are similar, and they each share common features, the iPhone 12 Pro Max display is of higher quality. The iPhone 12 Pro Max has a Super Retina XDR display with a resolution of 2778 x 1284, a contrast ratio of 2,000,000:1, and an 800 nits (typical) max
