The choice between the iPhone 16 Pro and 16 Pro Max boils down to screen size, battery life, and portability, with the Pro Max offering a larger screen and longer battery life while the Pro is more compact and manageable. Both phones share the same A18 Pro chip, 8GB of RAM, and camera features, including a 48MP main lens, 48MP ultrawide, and a 12MP telephoto with 5x optical zoom.
