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 sometimes get rumored feature leaks so far ahead of launch. The iPhone 17 series is no different – already we have some idea of what to expect from Apple's 2025 smartphone lineup.

If you plan to skip this year's iPhone 16, or if you're just plain curious about what's on the horizon, here are 12 rumored features that we are expecting to arrive in time for its successor, the iPhone 17 series, which is likely to be released in September 2025.

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 allegedly feature a "major redesign" that could feature a single rear camera located at the top-center of the device, along with a narrower Dynamic Island, according to Apple analyst Ming-Chi Kuo. However, one rumor claims the ‌battery will be around 6mm thick, suggesting that the device itself will be thicker than this. Apple's thinnest ever iPhone was the ‌iPhone‌ 6 at 6.9mm, meaning that the ‌iPhone 17‌ "Air" may not be much thinner than the 2014 flagship. The device is rumored to have a 6.5-inch display size, and may replace the iPhone 17 Plus model, but this is unconfirmed. Other potential features include an aluminum chassis, an A19 chip, an Apple-designed 5G modem, and an improved front camera. See our iPhone 17 "Slim" rumor roundup for more.

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. Rectangular Camera Bump

iPhone 17 Pro & iPhone 17 Pro Max

The ‌iPhone 17‌ Pro models are rumored to feature a new rear design combining aluminum and glass. The top half of the back will be aluminum, incorporating a "rectangular 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

This 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.

6. Apple-Designed Wi-Fi 7 Chip

iPhone 17 Pro & iPhone 17 Pro Max

Apple's premium 2025 models are expected to be equipped with an Apple-designed Wi-Fi 7 chip for the first time. Wi-Fi 7 support would allow the "Pro" models to send and receive data over the 2.4GHz, 5GHz, and 6GHz bands simultaneously with a supported router, resulting in faster Wi-Fi speeds, lower latency, and more reliable connectivity. The Wi-Fi chip would also allow Apple to further reduce its dependance on external suppliers like Broadcom, which currently supplies Apple with a combined Wi-Fi and Bluetooth chip for iPhones.

7. 48MP Telephoto Lens

iPhone 17 Pro Max

An upgraded 48-megapixel Telephoto lens on Apple's largest premium device is expected to be optimized for use with Apple's Vision Pro headset. That would make 2025's "Pro Max" the first iPhone to have a rear camera system composed entirely of 48-megapixel lenses, making it capable of capturing even more photographic detail.

8. 24MP Selfie Camera

All iPhone 17 Models

The iPhone 17 lineup will feature a 24-megapixel front-facing camera with a six-element lens, according to one rumor. The iPhone 14 and 15 feature a 12-megapixel front-facing camera with five plastic lens elements, and this year's iPhone 16 lineup features the same hardware. The upgraded resolution to 24 megapixels on the iPhone 17 will allow photos to maintain their quality even when cropped or zoomed in, while the larger number of pixels will capture finer details. The upgrade to a six-element lens should also slightly enhance image quality.

9. Scratch Resistant Anti-Reflective Display

All iPhone 17 Models

The iPhone 17 will feature an anti-reflective display that is more scratch-resistant than Apple's Ceramic Shield found on iPhone 15 models, according to one rumor, although the new iPhone 16 Pro models do have the latest-generation Ceramic Shield, which has an advanced formulation that is 2x tougher than glass on any other smartphone. The outer glass on the iPhone 17 is said to have a "super-hard anti-reflective layer" that is "more scratch-resistant." It's not clear whether Apple is planning to adopt the Gorilla Glass Armor that Samsung uses in its Galaxy S24 Ultra, but the description of Corning's latest technology matches the rumor.

10. More Memory

iPhone 17 Pro & iPhone 17 Pro Max

At least one model in Apple's iPhone 17 lineup will come with 12GB. Jeff Pu of investment firm Haitong has claimed that both Pro models will come with the upped RAM, while Apple analyst Ming-Chi Kuo believes only the iPhone 17 Pro Max will feature 12GB. In contrast, another reliable source has claimed that all iPhone 17 models will have 12GB of RAM. For comparison, the standard iPhone 15 and iPhone 15 Plus have 6GB of RAM, and the iPhone 15 Pro models have 8GB of RAM, while all iPhone 16 models have 8GB of RAM. Any such increase would allow for improved multitasking on the iPhone, as well as provide additional resources for Apple Intelligence features that require large-language models to be resident in memory.

11. Smaller Dynamic Island

iPhone 17 Pro Max

Apple's highest-end 2025 iPhone will feature a significantly narrower Dynamic Island, thanks to the device's adoption of a smaller "metalens" for the Face ID system, claims Haitong's Jeff Pu. While a traditional iPhone camera has curved lenses that redirect light towards the image sensor, a metalens is a thin and flat lens with microscopic patterns etched onto it that can focus light more precisely. Assuming this results in a narrowed Dynamic Island , it would be the first time that Apple has changed the feature since it debuted on the iPhone 14 Pro in 2022.

12. A19 Processor

All iPhone 17 Models

Apple typically upgrades iPhones with faster and more efficient chip technology each year. While we are not expecting the iPhone 17 series to get TSMC's next-generation 2-nanometer chips, Apple's A19 chip technology is likely to be built on an upgraded 3-nanometer process. The iPhone 17 Pro and iPhone 17 Pro Max are expected to include an A19 Pro chip, while the iPhone 17 and the iPhone 17 Air could have the standard A19 chip. TSMC is working on its N3P process, with mass production set to begin in late 2024, so that's the chip technology that we're expecting Apple will use for the iPhone 17 lineup. Compared to earlier versions of 3nm chips, the N3P chips offer increased performance efficiency and increased transistor density.
