Like the iPhone 15 series, this year’s lineup is expected to stick with four models – iPhone 16, iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max – although there are plenty of design differences and new features to take into account.

This year’s iPhone 16 Pro and iPhone 16 Pro Max are rumored to be getting bigger display sizes, increasing to 6.27- and 6.86-inches, respectively. For comparison, the iPhone 15 Pro and iPhone 15 Pro Max are equipped with 6.1-inch and 6.7-inch displays, respectively. The new display sizes would be the largest ever for the iPhone.

Its base models will feature a vertical camera arrangement with a pill-shaped raised surface, instead of a diagonal camera arrangement like the iPhone 15. The new camera bump features two separate camera rings for the Wide and Ultra Wide cameras. The vertical camera layout is expected to enable Spatial Video recording, which is currently limited to the iPhone 15 Pro models.

Rumors suggest the ‌iPhone 16‌ and iPhone 16 Pro Max will feature larger batteries than their predecessors, although the smaller iPhone 16 Pro device could see the biggest improvement, while the ‌iPhone 16‌ Plus may have reduced capacity. The iPhone 16 is said to have a 6% increase over the iPhone 15, with the iPhone 16 Pro Max gaining a 5% increase, and the iPhone 16 Pro seeing a 9% increase. In contrast, the iPhone 16 Plus is rumored to have a 9% reduction in capacity. On the other hand, Apple could also potentially use stacked battery technology to increase energy density and prolong lifespan across the lineup.

All iPhone 16 models will have a new "Capture Button" dedicated to triggering image or video capture. The button will add features like the ability to zoom in and out by swiping left and right on the button, focus on a subject with a light press, and activate a recording with a more forceful press. The Capture Button will be located on the bottom right side of the ‌iPhone 16, and will take the place of the mmWave antenna on U.S. ‌iPhone‌ models, with the antenna relocating to the left side of the device below the volume and Action buttons.
