Compare iPhone Duo vs iPhone 16 Pro Max
Which one is best for you?
iPhone Duo is Apple's first foldable phone with the largest iPhone display ever, while iPhone 16 Pro Max is the biggest non-folding phone in the 2024 release — both feature titanium frames, 48MP camera systems and 5G, but the Duo adds a foldable form factor and a next-generation A20 Pro chip.
Both phones are built with titanium frames and 48MP camera systems, giving you premium materials and strong photography on either. Each support WiFi 7, 5G, eSIM and USB-C charging, so you stay connected and charged on the go. The Duo offers Bluetooth 6, while 16 Pro Max offers an older Bluetooth 5.3
iPhone Duo stands out with its foldable 7.6-inch inner display, which is larger than iPhone 16 Pro Max's 6.9-inch screen and can be folded into a stand for hands-free viewing. The A20 Pro chip is vapour-cooled and purpose-built for AI, offering a clear step up from iPhone 16 Pro Max's A18 Pro chip for power users and creators. A dual-battery system delivers substantially more video playback, and the nano-texture inner display reduces glare outdoors. iPhone 16 Pro Max uses Face ID and keeps a traditional, large-screen iPhone design that we’re familiar with.
Choose iPhone Duo if you want a foldable phone with the biggest iPhone display, the latest AI-focused chip and exceptional battery life. Choose iPhone 16 Pro Max if you want a large-screen iPhone with a titanium frame and pro camera features in a familiar, non-folding design.
