Apple's iPhone development roadmap runs several years into the future and the company is continually working with suppliers on several successive iPhone models simultaneously, which is why we often get rumored features months ahead of launch. The iPhone 17 series is no different, and we already have a good idea of what to expect from Apple's 2025 smartphone lineup.

If you skipped the iPhone 16, or if you're just plain curious about what's on the horizon, here are 17 rumored features that we are expecting to arrive in time for Apple's successor lineup, the iPhone 17 series, which is likely to be released around mid-September.
1. iPhone 17 "Air"
iPhone 17 Plus?
Apple plans to launch an all-new iPhone 17 model with a "significantly thinner" design, reports The Information. The device, which could be called "iPhone 17 Air," will feature a "major redesign" that will feature a single rear camera located on a horizontal camera bar running along the top of the device, along with a narrower Dynamic Island, according to Apple analyst Ming-Chi Kuo. Apple analyst Ming-Chi Kuo believes the iPhone 17 Air will be 5.5mm thick at its thinnest point, which likely means it will have a 5.5mm chassis with a thicker rear camera bump area. The device is rumored to have a 6.6-inch display size, and is likely to replace the Plus model in Apple's lineup. Other reported features include an aluminum chassis, an A19 chip, Apple's C1 modem, an Action button, a Camera Control button, and a 24MP front camera.

2. New All-Aluminum Design
All iPhone 17 Models
Apple is reportedly planning to bring all its devices back to aluminum with the iPhone 17 lineup. The two flagship iPhone 17 Pro models will mark the return of aluminum frames to high-end iPhones for the first time since Apple began distinguishing between Pro and non-Pro models. In recent years, aluminum frames have been reserved for lower-end devices like the iPhone SE and iPhone 16, while premium models featured stainless steel frames until the iPhone 15 Pro, which introduced a titanium chassis as a major upgrade. This shift in materials for the iPhone 17 lineup signals a unified approach, with aluminum frames set to return across the entire device range.
3. Significantly Redesigned Camera
iPhone 17 Pro & iPhone 17 Pro Max
This year's iPhone 17 Pro models will have a major redesign, specifically centering around changes to the rear camera module. Apple will move away from the familiar square camera bump to a distinctive aluminum camera bar that spans the device's width, according to recent reports. The camera area will be the same color as the rest of the device. The redesigned camera module is not expected to extend to the regular iPhone 17.
The devices are rumored to feature a new rear design combining aluminum and glass. The top half of the back will be aluminum, incorporating a new camera bump made from aluminum instead of the traditional 3D glass. The bottom half will remain glass to enable wireless charging. While Apple has used a glass back since the iPhone 8 and iPhone X in 2017, earlier iPhone models—except the iPhone 3G, iPhone 3GS, and iPhone 5C—had aluminum rears. Additionally, the aluminum camera bump on the iPhone 17 Pro will reportedly be larger than in previous models, according to The Information.
4. New Display Sizes
iPhone 17 & iPhone 17 Plus
Last year's iPhone 16 Pro and iPhone 16 Pro Max got bigger display sizes, going from 6.12- and 6.69-inches to 6.27- and 6.86-inches, respectively. For 2025, Apple is also expected to bring the larger 6.27-inch display size to its standard iPhone model, while the equivalent "iPhone 17 Plus" model (provisionally called "iPhone 17 Air") could adopt completely new display dimensions.
5. 120Hz ProMotion (Always-on Display)
iPhone 17 & iPhone 17 Plus
Apple intends to expand ProMotion to all iPhone models in 2025, allowing all models to ramp up to a 120Hz refresh rate for smoother scrolling and video content when necessary. Previously, only "Pro" models in Apple's iPhone lineup have had the feature. Notably, ProMotion would also enable the display on the iPhone 17 and iPhone 17 "Air" to ramp down to a more power-efficient refresh rate as low as 1Hz, allowing for an always-on display that can show the Lock Screen's clock, widgets, notifications, and wallpaper even when the device is locked...
