Compare iPhone Duo vs iPhone 16 Pro

Which one is best for you?

iPhone Duo is Apple's first foldable phone with the largest iPhone display ever, while iPhone 16 Pro is a compact pro-grade phone from the 2024 range. Both include titanium frames and 48MP camera systems, but the Duo adds a foldable feature and a next-generation A20 Pro chip. 

Each offers USB-C connectivity, 5G, Wi-Fi 7 and eSIM, so you can stay connected on the go. The Duo adds Bluetooth 6, while iPhone 16 Pro keeps things focused with its pro camera features and compact pro design. 

iPhone Duo has a foldable 7.58-inch inner display, which dwarfs iPhone 16 Pro's 6.27-inch screen and can be folded into a stand for hands-free use. The A20 Pro chip is vapour-cooled and purpose-built for AI workloads, offering a clear step up from iPhone 16 Pro's A18 Pro chip for creators and power users. A dual-battery system delivers substantially more video playback, and the nano-texture inner display cuts glare when you are outside. iPhone 16 Pro uses Face ID and keeps a traditional, pocket-friendly pro design that is easy to carry. 

Choose iPhone Duo if you want a foldable phone with the biggest iPhone display, the latest AI-focused chip and exceptional battery life. Pick iPhone 16 Pro if you want a compact, pro-grade phone with a titanium frame and pro camera features.
