Apple's iPhone Pro models have always shot straight to the top of the best iPhones list each year, but the latest refresh is different.

For starters, the iPhone 17 Pro and 17 Pro Max ditch the titanium casing found on previous models. Instead, we get a unibody design with an aluminium build, covered in Apple's Ceramic Shield glass tech.

There's an added extra on each too, in the form of a much-larger camera module than we've seen before. And a new vapor chamber has been included inside to ensure the phones remain cool during gaming and other processing hungry tasks.

Perhaps the most impressive new feature is a much larger battery – with eSIM only models gaining extra power for longer video playback and other use. They feature up to 39 hours of playback time, it's claimed.

56% larger camera sensor

As well as the other camera units on the rear of the new Pro models, there's a much larger telephoto sensor. It is capable of 4x zoom optically, but also 8x when using Apple's new Fusion camera technology (utilising the other sensors too).

Digital zoom goes up to 48x now, while the front camera has been boosted up to 18-megapixels. It supports Center Stage for photography too – allowing multiple faces to be detected and the frame to resize as appropriate.

All three cameras on the rear are 48-megapixel and the iPhones now support ProRes RAW and Genlock, too.

All about that processing

Like the iPhone 17 Air, the new iPhone 17 Pro models run on the new A19 Pro chipset, while storage starts at 256GB. You can now go up to 2TB on the iPhone 17 Pro Max, too.

They'll each be available from 19 September, priced from $1,099. UK pricing is to follow.
