Compare iPhone Duo vs iPhone 16

Which one is best for you?

iPhone Duo and iPhone 16 both bring Apple's 48MP Fusion camera system and 5G connectivity, but iPhone Duo takes things in a new direction with a foldable design, a larger inner display, and a more advanced A20 Pro chip. 

Both phones feature a 48MP Fusion camera with a Main and Ultra Wide lens, so you can capture detailed photos and wide shots with either. Each also supports 5G, WiFi 7, and MagSafe charging, keeping you connected and powered up throughout the day. iPhone 16 offers a compact 6.1-inch Super Retina XDR display, while iPhone Duo gives you a 5.4-inch outer display and a 7.6-inch inner folding display — the largest iPhone display yet. Both also come with Ceramic Shield protection for added durability. 

iPhone Duo is built for power users and creators who want more screen to work with. Its A20 Pro chip with a Dual 16-core Neural Engine is purpose-built for AI workloads, delivering faster performance than iPhone 16's A18 chip. The foldable design is poseable and standable, so you can prop it up for video calls or streaming without a stand. iPhone Duo also adds a nano-texture inner display to reduce glare, an under-display FaceTime camera, and a dual-battery system that gives you up to 44 hours of video playback on the outer display. iPhone 16, in comparison, offers up to 22 hours of video playback and a simpler, lighter design. 

Choose iPhone Duo if you want a foldable display and the latest AI performance for multitasking and content creation. Choose iPhone 16 if you want a dependable, compact phone at a more accessible price.
