One advantage for the older iPhone 14 Pro Max is its thinner, 7.8 mm profile, while the iPhone 17 Pro Max measures 8.65mm thick. However, the 17 Pro Max at 233 grams still weighs a bit less the 14 Pro Max with its 240 grams. Storage-wise, the iPhone 14 Pro Max was the last Pro iPhone to boast a 128GB version along with 256GB, 512GB, and 1TB ones. MagSafe is available on both, but the 17 Pro Max supprots the faster 25W charging speeds compared to 15W on the 14 Pro Max.
