Apple unveiled its new pro-grade smartphones at the annual Apple Event on Tuesday: The iPhone 15 Pro and the iPhone 15 Pro Max.

The new phones look roughly the same as last year. Two glass panes sandwiched in a metal frame, and the pill-shaped Dynamic Island being the only interruption on the displays. But the design has been refined in several ways.

The frame on the Pro models is now made of titanium and has a brushed look, as opposed to the shiny, stainless steel frame on last year’s models. Not only is titanium cool looking, it’s also more durable while making the phones lightly lighter. The displays are the same size: 6.1 and 6.7 inches.

There's also a new, Action Button replacing the mute toggle switch, with the benefits of having haptic feedback and being more customizable.

The chip that powers the iPhone 15 Pro is Apple's new A17 Pro chip. It's a 3 nanometer chip, with 19 billion transistors, 6 main cores (2 performance cores and 4 efficiency cores), and the 16-core Neural Engine.

The biggest improvement is the camera. On the iPhone 15 Pro Max (but not the regular iPhone 15 Pro), there’s a new telephoto camera, with a new tetra-prism design, increasing the zoom up to 5x (the iPhone 15 Pro maxes out at 3x).

But the main, wide camera, as well as the ultrawide camera (which are the same on both the iPhone 15 Pro and Pro Max) have received significant improvements as well.
