In 2025, Apple is rumored to be adding an all-new model to its flagship iPhone 17 lineup, tentatively referred to as "iPhone 17 Air," with the device expected to have a thinner design than current iPhone models. While Apple's iPhone 16 series is only be a couple of months old, when you consider that we learned about larger displays on the iPhone 16 Pro models way back in May 2023, rumors about a next-generation iPhone aren't all that unusual so far ahead of time.
Apple will sell the "iPhone 17 Air" alongside a standard iPhone 17, an iPhone 17 Pro, and an iPhone 17 Pro Max. Apple is said to be eliminating the "Plus" phone from the 2025 lineup due to poor sales. Below, we've brought together all of the rumors we have heard so far from reputable sources about Apple's slim new iPhone
iPhone 17 Air: Rumors So Far
iPhone Air or iPhone Slim?
Apple's rumored slimmer iPhone 17, previously referred to as the iPhone 17 "Slim," is expected to be positioned as an iPhone "Air" to boost sales, according to Bloomberg's Mark Gurman. YouTuber Jon Prosser was first to suggest that the device could be positioned as an "iPhone Air," and Gurman seems to support this idea. Early rumors suggested it would be a replacement for the "Plus" iPhone, but Apple analyst Ming-Chi Kuo disagrees, and believes the iPhone 17 "Air" will represent a new strategic approach in Apple's iPhone lineup, offering a thinner design that sits between the iPhone 17 and iPhone 17 Pro. Gurman has compared the device to the original MacBook Air from 2008, which sat between the regular MacBook and MacBook Pro in the lineup.
Thinner Design
According to The Information, Apple's all-new iPhone 17 model next year will have a "significantly thinner" design with an aluminum chassis, rather than a titanium casing like Apple's current Pro models. However, the device's reduced thickness is said to be dependent on manufacturing a battery with a thinner substrate, and Apple has allegedly run into technical challenges. The battery will purportedly be around 6mm thick. If you consider that Apple's thinnest ever iPhone was the iPhone 6 at 6.9mm, then the iPhone 17 "Slim" is unlikely to be much thinner than the 2014 flagship. The Information claims that the device will feature a narrower Dynamic Island (potentially due to Apple's adoption of a smaller "metalens" for the Face ID system) although this specific claim has since been contested.
Embedded SIMs
As a result of the thinner design, Apple's rumored device relies on embedded SIMs, a chip significantly smaller than a physical SIM card tray that Apple first introduced in the iPhone in 2018, according to The Information. However, this could cause trouble for sales of the device in China, where eSIMs have still not been approved by regulators. Apple is also said to be compromising on other aspects of the slim iPhone's design to ensure its thinness. For example, the device will reportedly only have a single speaker in its earpiece because there is no room for a second speaker at the bottom, which is standard in other models.
Smaller Display
The first details about the size of the device's display arrived courtesy of Haitong International Securities analyst Jeff Pu, who said it would be 6.6 inches. Apple analyst Ming-Chi Kuo has since corroborated Pu's claim. However, according to Display Supply Chain Consultants (DSCC) analyst Ross Young, it will feature a 6.55-inch display. For comparison, the iPhone 16 Plus has a 6.7-inch display. Apple is still said to be testing different designs for the slimmer phone, so the display size could always change between now and the device's launch.
ProMotion Support
Apple intends to expand ProMotion to the entire lineup in 2025, including the iPhone 17 "Air," allowing all iPhone 17 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 supported ProMotion. Notably, ProMotion would also enable the display on the 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.
Relocated Cameras
The Information claimed that the iPhone 17 "Slim" or "Air" will have cameras in locations we haven't seen before on an iPhone. According to a May report, the rear cameras could be moved to the "top center" of the device. Some Android phones like Google's Pixel 8 Pro have rear cameras in a top-center position, but Apple's iPhone camera system has occupied the top-left corner ever since the 2007 model. To add to the intrigue, Apple analyst Ming-Chi Kuo has claimed that the device will have only one camera, as opposed to two or three. The Information has since released a report corroborating Kuo's claim that the device have a single lens within a large, centered camera bump on its back.
Anti-Reflective Coating
All iPhone 17 models will feature an anti-reflective display that is more scratch-resistant than Apple's Ceramic Shield found on iPhone 15 models, according to Chinese Weibo leaker Instant Digital. The outer glass on the iPhone 17 series 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.
ProMotion Technology
According to The Elec, all iPhone 17 models will feature OLED displays with low-power backplane technology, bringing ProMotion to Apple's non-Pro iPhone models for the first time. ProMotion allows the display to ramp up to a 120Hz refresh rate for smoother scrolling and video content when required. ProMotion also allows the display to ramp down to a more power-efficient refresh rate as low as 1Hz, which is why the iPhone 16 Pro screens feature an always-on capability that shows the Lock Screen's clock, widgets, notifications, and wallpaper even when the device is locked.
Improved Selfie Camera
According to Apple analyst Ming-Chi Kuo, the entire iPhone 17 lineup will feature a 24-megapixel front-facing camera with a six-element lens. 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 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.
More Memory
Haitong analyst Jeff Pu claims the iPhone 17 "Slim" or "Air" will feature 8GB of RAM, compared to 6GB of RAM on the iPhone 15 Plus. It's worth noting that all iPhone 16 models are fitted with 8GB of RAM – a hardware requirement of on-device Apple Intelligence – so it's almost a surety that the slim device will follow suit.
Faster Processor
According to The Information and Haitong International analyst Jeff Pu, the device will be equipped with Apple's A19 chip, which is likely to be based on an optimized version of TSMC's 3nm process, possibly N3P or N3X. In contrast, the iPhone 17 Pro and iPhone 17 Pro Max are expected to include an A19 Pro chip. Compared to earlier versions of 3nm chips, the N3P chips offer increased performance efficiency and increased transistor density.
Custom 5G Modem and Wi-Fi Chip
The slim device may also be one of the first iPhones to use an Apple-made 5G modem, second only to the forthcoming iPhone SE 4. Apple's new modem could bring enhancements, such as improved speed, better energy efficiency. According to Apple analyst Ming-Chi Kuo, at least one iPhone 17 model launching next year will be equipped with an Apple-designed Wi-Fi 7 chip, and Kuo also expects Apple's 5G modem to be used in the rumored ultra-thin iPhone 17 model.
Potentially Higher Price
The Information reported that the slimmer iPhone 17 could have a higher price tag than the Pro Max model (the iPhone 16 Pro Max starts at $1,199) despite suggestions that it will not be as feature-rich as Apple's top-tier Max. It has been argued that the "cool factor" alone of a completely new thinner design could entice customers. That said, Haitong International analyst Jeff Pu believes the device will essentially be a mid-tier iPhone. Meanwhile, Gurman believes that the design of the iPhone 17 "Air" will "just be a step toward something better" since Apple will eventually want to "squeeze the power of a Pro model into this smaller design." However, he does not expect this to occur before 2027 at the earliest.
