What’s New in the iPhone 17 Lineup?

The iPhone 17 series is poised to shake up Apple’s smartphone offerings. The most significant change is the replacement of the iPhone 16 Plus with the iPhone 17 Air, a super-slim model designed to rival the thinnest smartphones, like the Samsung Galaxy S25 Edge.

All models are expected to feature 120Hz ProMotion displays, a first for non-Pro iPhones, enabled by LTPO OLED panels for smoother scrolling and gaming. The lineup will run on iOS 26, unveiled at WWDC 2025, with a “Liquid Glass” design aesthetic that complements the event’s vibrant, flowing logo.

How Thin Is the iPhone 17 Air?

The iPhone 17 Air is the star of the rumors, with a reported thickness of around 5.5mm to 6.25mm, making it Apple’s slimmest iPhone yet.

Analyst Ming-Chi Kuo suggests a 5.5mm chassis, while Bloomberg’s Mark Gurman estimates it’s about 2mm thinner than the iPhone 16 Pro’s 8.25mm.

However, this sleek design comes with trade-offs: a single-lens 48MP rear camera and a 2,800mAh battery, potentially 20% smaller than the iPhone 16’s. To compensate, Apple may reintroduce a MagSafe battery pack.

The Air is expected to be priced between the standard iPhone 17 ($799) and Pro models ($999), likely around $899-$949.

What Upgrades Are Coming to the iPhone 17 Pro and Pro Max?

The iPhone 17 Pro and Pro Max are set for significant design and performance upgrades. Leaks indicate a hybrid titanium-aluminum chassis for better heat dissipation and reduced weight compared to the iPhone 16 Pro’s titanium frame.

A new horizontal camera bar, reminiscent of the Google Pixel 9 Pro, will house a 48MP telephoto lens with up to 8x optical zoom, a jump from the 5x zoom on the iPhone 16 Pro.

The A19 Pro chip, built on a 3nm process, promises enhanced performance and efficiency. A vapor chamber cooling system may also be included to manage heat during intensive tasks.

Will All Models Get ProMotion Displays?

For the first time, all iPhone 17 models are expected to feature 120Hz ProMotion displays, a feature previously exclusive to Pro models.

This upgrade, enabled by LTPO OLED panels, will deliver smoother scrolling, animations, and up to 120fps gameplay.

While always-on display functionality is possible due to the LTPO technology’s 1Hz refresh rate capability, it’s unclear if Apple will extend this to non-Pro models or keep it Pro-exclusive.

This change levels the playing field, making the standard iPhone 17 and iPhone 17 Air more premium.

What Colors and Design Changes Are Expected?

Color options are set to make a bold statement. The iPhone 17 Pro and Pro Max may introduce a copper-like orange shade, alongside dark blue, gray, silver, and black.

The iPhone 17 and iPhone 17 Air are rumored to come in vibrant hues like purple, green, blue, black, and a light blue exclusive to the Air.

Leaked case designs suggest new “TechWoven” fabric cases to replace the unpopular FineWoven series, with cutouts for a magnetic crossbody strap accessory. The standard iPhone 17’s display is expected to grow from 6.1 to 6.3 inches, while the Air may feature a 6.6-inch screen.

Are There Any Camera and Chip Improvements?

Camera upgrades are a focal point. All iPhone 17 models are rumored to feature 24MP front cameras, doubling the resolution of the iPhone 16’s 12MP selfie lens for sharper images. The Pro models’ 48MP telephoto lens with 8x optical zoom is a standout, while the iPhone 17 Air may stick to a single 48MP wide-angle rear camera.

The A19 chip (A19 Pro for Pro models) will power the lineup, offering improved performance and energy efficiency. There’s debate over the iPhone 17 Air’s chip, with some sources suggesting an A19 and others an A19 Pro, but all agree it will support Apple Intelligence features.

Could Pricing Change Due to Tariffs?

Pricing rumors suggest a potential $50-$100 increase across the lineup due to tariffs and advanced features. The iPhone 17 may start at $799-$899, the iPhone 17 Air at $899-$949, and the iPhone 17 Pro and Pro Max at $999-$1,299.

Some reports indicate Apple may offset costs by increasing base storage to 256GB for Pro models. The Wall Street Journal notes the iPhone 17 Air could match the iPhone 16 Plus’s $899 price, making it a mid-tier option. These price hikes reflect Apple’s push for premium features while navigating supply chain challenges.

What Else Might Be Revealed?

Beyond iPhones, the Apple Watch Series 11, Ultra 3, and SE 3 are expected, with features like satellite connectivity for the Ultra 3 and larger displays.

AirPods Pro 3 may debut with health sensors, such as in-ear heart rate monitoring, and improved noise cancellation.

An updated Apple TV 4K and AirTag 2 are also rumored, though a HomePod with a screen is likely delayed to 2026. iOS 26, with its Liquid Glass design and enhanced Apple Intelligence, will power the new devices, with a release expected around September 15.

Some Closing Thoughts:

The Apple September Event 2025 is shaping up to be a game-changer, with the iPhone 17 series leading the charge.

From the ultra-thin iPhone 17 Air to Pro models with bold new designs, Apple is set to redefine its flagship lineup.
