Apple is expected to revamp the design of the iPhone 17 series, and the ultra-thin race is clearly led by the iPhone 17 Air.

The iPhone 17 Air features a minimalist rear camera bar housing a single lens – a look reminiscent of the Google Pixel. This clean approach gives the device a sleek, refined appearance.

In contrast, the iPhone 17 Pro Max retains its bulky triple-lens array, with three prominent circular modules that some critics argue make it one of the least aesthetically pleasing iPhones ever.

The most impressive design feat of the iPhone 17 Air is its 5.5 mm thickness and weight of just 146g – an engineering marvel. However, concerns about durability remain. Apple is rumored to be using a 7000-series aluminum frame and Ceramic Shield glass on both sides to mitigate this.

Meanwhile, the iPhone 17 Pro Max is expected to measure 8.725 mm thick and weigh around 227g, maintaining the sturdy feel the Pro Max series is known for.

120Hz displays across the board

One long-awaited upgrade is reportedly coming to all iPhone 17 models – 120Hz ProMotion displays.

The iPhone 17 Air is expected to sport a 6.6-inch OLED screen with 1320 x 2868 resolution, a pixel density of 458 PPI, peak brightness of 2000 nits, and 1000 nits in typical conditions.

The iPhone 17 Pro Max, on the other hand, keeps the 6.9-inch size but adopts Samsung’s new M14 OLED panel, which may reach an impressive 3000 nits in peak brightness. It’s also rumored to feature LDTEE technology for enhanced performance and durability – though it’s unclear whether the Air will receive this tech.

Performance and software: A clear divide

All iPhone 17 models are expected to run on the new A19 chip. While early rumors suggested a 2nm process, it's now likely based on TSMC’s improved 3nm node.

The iPhone 17 Air will reportedly use the standard A19 chip with 8GB RAM, while the iPhone 17 Pro Max will pack the A19 Pro chip with 12GB RAM.

Storage tiers differ too: the Air is expected to offer 128GB, 256GB, and 512GB options, while the Pro Max starts at 256GB and goes up to 1TB.

Both models will ship with iOS 26, but a deeper dive into the OS is expected in a separate feature.

Camera systems: Simplicity vs sophistication

The iPhone 17 Air is rumored to carry a single 48MP rear camera, likely similar to that of the iPhone 16e. This minimalist setup caters to users who prioritize form over function.

The iPhone 17 Pro Max, meanwhile, is a powerhouse with a triple 48MP camera system. Leaks suggest upgrades to the telephoto lens beyond the previous 12MP unit, while the primary and ultra-wide sensors may carry over from the iPhone 16 Pro Max.

As always, Apple's post-processing algorithms and AI will heavily influence photo quality, so the real story will unfold once hands-on reviews and sample shots arrive.

Battery and charging: A trade-off in thinness

Unsurprisingly, the ultra-thin iPhone 17 Air is said to feature a modest 3000mAh battery. While small, Apple’s software optimization may keep it practical for everyday use.

In contrast, the iPhone 17 Pro Max may get a battery upgrade from 4700mAh to possibly near 5000mAh, delivering significantly better endurance.

Both models may support 35W fast charging – a step forward for Apple, though still behind Android rivals like OnePlus and Motorola that offer over 100W.

The verdict: Different phones for different users

The iPhone 17 Air is designed for users who value style, portability, and simplicity. It's ideal for those who don’t need multi-camera setups or heavy gaming performance but want a fresh, minimalist iPhone experience.

The iPhone 17 Pro Max remains Apple’s most powerful offering: high performance, pro-level cameras, long battery life, and the brightest display. It targets creative professionals, gamers, and users who want the best tech Apple has to offer.

Ultimately, price will be the deciding factor. If the iPhone 17 Air is competitively priced, it could be a compelling choice in the premium ultrathin category. However, if it’s priced close to the Pro Max, buyers will need to weigh features versus form carefully.
