The upcoming iPhone 16 and iPhone 16 Pro are still months away from their expected launch this fall, but a new set of images published online may give us a better sense of their potential features. Among the revelations, the iPhone 16 may include an action button, similar to the one on last year's iPhone 15 Pro, and it may have redesigned cameras in a vertical stack.

AppleInsider published a series of photos it says show dummy 3D prints of the upcoming iPhone 16 and iPhone 16 Pro from an unnamed leaker. Aside from the action button and reworked cameras on the iPhone 16, AppleInsider also said its source found the iPhone 16 Pro to be "slightly larger" than its predecessor. Analysts had earlier said they expect the Pro model screens will grow somewhat.

The new details suggest that a series of expected hardware updates are likely for this year's new iPhones. Apple typically announces new iPhones around September, and the company tends to offer incremental upgrades to each new phone, introducing, over the period of several years, better cameras, screens and battery life, features that end up seeming like major upgrades when people get around to buying a new phone. 

Last year, Apple added a new titanium frame, action button and USB-C charging to its iPhone 15 Pro, which starts at $999. For its entry-level iPhone, Apple followed its well-worn strategy of trickling pro features down to the mainstream, adding the iPhone 14 Pro's well-received Dynamic Island to the $799 iPhone 15, along with USB-C charging.

AppleInsider didn't indicate whether its leaker had divined a reason for the iPhone 16's shifted camera placements, but the two lenses will now reportedly be stacked one on top of the other, instead of diagonally. Apple has previously said it uses stacked lenses on the iPhone 15 Pro for spatial video capture, a key new technology the company highlighted as part of its $3,499 Apple Vision Pro headset, released in February.

Though AppleInsider's leaks appear to confirm many previous rumors, not all renders and 3D prints are accurate, something the rumor blog notes itself in its report. Apple didn't immediately respond to a request for comment about the veracity of the leaks.
