Highly anticipated: The new Apple iPhone 15 Pro and iPhone 15 Pro Max feature 6.1-inch and 6.7-inch displays, and utilize a grade 5 titanium alloy that's stronger, more durable, and lighter than the stainless steel used in the previous flagships phones.

The titanium alloy makes this the lightest iPhone Pro lineup ever at 187 grams (6.60 ounces) and 221 grams (7.81 ounces), respectively. For comparison, last year's Pro and Pro Max models weighed 206 grams (7.27 ounces) and 240 grams (8.47 ounces).

Apple has also replaced the ring / silent switch with a customizable action button. This new button can still function as a ring / silent switch by simply pressing and holding the button to toggle between the two modes, but can also be programmed to perform a variety of other tasks such as launching a voice memo, bringing up the camera, activating an accessibility feature, or launching a specific app.

Powering the iPhone 15 Pro is an all-new A17 Pro SoC, the industry's first 3nm chip. It features 19 billion transistors and is comprised of a six-core CPU (two performance cores, four efficiency cores) alongside a 16-core neural engine that can process up to 35 trillion operations per second, and a six-core GPU with hardware-accelerated ray tracing that is said to offer up to four times faster ray tracing compared to software ray tracing on the A16 Bionic.

A phone's camera system is one of its key selling points, and Apple reserved the very best for its iPhone 15 Pro Max. The star of the show here is the 12-megapixel telephoto with a 5x optical zoom (120mm), an f/2.8 aperture, and 3D sensor-shift optical image stabilization.

All new iPhones for 2023 have made the switch from Apple's proprietary Lightning connector to USB-C.
