Compare iPhone Duo vs iPhone 16 Plus
Which one is best for you?
iPhone Duo brings a foldable design and the largest iPhone display ever to the lineup, while iPhone 16 Plus offers a large, traditional screen at a more accessible price — both share a 48MP camera system and Apple Intelligence, but they suit different priorities when it comes to screen size and form factor.
Both phones feature a 48MP dual-camera system with an Ultra Wide camera, so you can capture detailed photos and wide shots with either. Each runs Apple Intelligence for smarter writing, summarised notifications and a more helpful Siri. Both have Ceramic Shield front protection and USB-C and MagSafe wireless charging. The Duo offers a more advanced Ceramic Shield 2 front for 3x better scratch resistance.
iPhone Duo stands out with its foldable 7.6-inch inner display, which is larger than iPhone 16 Plus's 6.7-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, making it ideal for creators and power users who push their phone to its limits. A dual-battery system gives you substantially more video playback than the 16 Plus's 22 hours, and the nano-texture inner display reduces glare outdoors. iPhone 16 Plus keeps things straightforward with a large, bright display in five vibrant colours and an aerospace-grade aluminium frame.
Choose iPhone Duo if you want a foldable phone with Apple’s biggest Super Retina XDR display, top-tier performance and exceptional battery life. Opt for iPhone 16 Plus if you want a large-screen phone with a great camera and all-day battery at a more affordable price.
