Apple has unveiled the iPhone 17 lineup at its September showcase, with this year’s phones packing more visible changes than the incremental updates of the iPhone 16.

The standout newcomer is the iPhone Air. Just 5.6mm thick and weighing 165 grams, it’s Apple’s thinnest smartphone yet.

Despite the slim profile, it runs the same A19 Pro chip as the Pro models and introduces an upgraded C1X 5G modem. The Air carries a single 48-megapixel rear camera, offers up to 1TB of storage, and delivers 27 hours of video playback. Prices start at A$1,799.

The lineup spans three other models: the standard iPhone 17 and the high-end iPhone 17 Pro and Pro Max.

The iPhone 17 keeps its A$1,399 starting price but doubles baseline storage to 256GB. It gets a redesigned vertical camera bump, a sharper 48-megapixel ultrawide, and a new 18-megapixel selfie camera with Center Stage. Its 6.3-inch OLED display now supports ProMotion with refresh rates from 1Hz to 120Hz and brightness up to 3,000 nits.

iPhone Air, Apple’s slimmest phone yet

Apple’s pro-tier phones push harder on performance. The iPhone 17 Pro and Pro Max swap titanium frames for stamped aluminum, paired with vapor chambers that improve sustained performance by 40% over last year. Both run the A19 Pro chip and start at 256GB storage, with the Pro Max stretching up to 2TB.

Camera upgrades dominate the Pro story.

All three lenses, including the telephoto, jump to 48 megapixels. The Pro Max supports optical zoom up to 8x and digital zoom up to 40x. Apple has also redesigned the front-facing camera with a larger square sensor, enabling horizontal selfies without rotating the phone. The Pro models ship in white, dark blue and bright orange.

Battery life ranges from 27 hours of video on the Air to 39 hours on the Pro Max. All four phones gain Wi-Fi 7 support, Ceramic Shield 2 glass, and iOS 26’s redesigned “Liquid Glass” interface.

Preorders open Friday, with retail launch set for September 19.

Apple has also refreshed its entire smartwatch lineup for the first time in three years, unveiling the Series 11, SE 3, and Ultra 3.
