The iPhone 17 Pro Max is Apple’s most advanced iPhone yet, featuring a 6.9-inch Super Retina XDR display, A19 Pro chip, 48MP triple rear cameras, and a durable aluminum unibody design. Design and Build The iPhone 17 Pro Max introduces a heat-forged aluminum unibody that replaces the titanium or stainless steel used in previous Pro models, offering improved thermal conductivity and durability while reducing weight. The back is protected by Ceramic Shield 2, providing enhanced scratch resistance, and the front display has 3× better scratch resistance than prior models. The device is available in Cosmic Orange, Deep Blue, and Silver. A vapor chamber inside helps dissipate heat from the A19 Pro chip, allowing sustained high performance.
