Apple is preparing to make headlines with what may be its sleekest and most visually striking iPhone to date — the iPhone 17 Air (also potentially dubbed the iPhone 17 Slim). This device marks a significant shift in Apple’s smartphone lineup and appears to be the company’s answer to a growing demand for thinner, lighter, and more futuristic mobile devices.
Positioned to replace the current “Plus” models, the iPhone 17 Air is rumored to offer an entirely new form factor with a dramatically thin profile of just 5.5mm. This launch reflects Apple’s broader design ambitions over the next several years, and the iPhone 17 Air is just the start of a lineup evolution that stretches through 2027.
Let’s break down everything we know so far about this device, what’s coming in future iterations, and what this tells us about Apple’s long-term strategy in the smartphone market.
A Next-Gen iPhone in the Making
Apple will launch the iPhone 17 Air in 2025, aiming to redefine thin smartphone design with a 5.5mm chassis, significantly thinner than existing models.
It will feature a 6.6-inch display, placing it between the Pro and Pro Max models in screen size.
This new model is expected to replace the current Plus version in the lineup, with a starting price between \$900 and \$1000.
Leaked schematics confirm its ultra-thin build and position it as a premium yet lighter alternative.
Analyst Ming-Chi Kuo reports that Apple is already preparing a larger version of this model, likely to be launched as the iPhone 19 Air in 2027.
The iPhone 18 Air, set for fall 2026, will be a minor refresh of the 17 Air — focusing on incremental updates.
A 6.9-inch prototype for a slim iPhone had been considered in early development but was scrapped due to concerns over structural integrity, echoing fears from the “Bendgate” scandal with the iPhone 6 Plus.
Bloomberg’s Mark Gurman previously revealed that Apple paused the larger prototype to prevent issues with bending — yet hints suggest Apple hasn’t given up on this idea.
There’s growing speculation that Apple’s 2027 version (iPhone 19 Air) could be the resurrection of the original 6.9-inch slim prototype.
In parallel, Apple plans a radical redesign of the iPhone Pro series in 2026 and 2027, aligning with the broader shift in hardware design philosophy.
Apple is also said to be working on its first foldable iPhones, with a tentative launch set for late 2026, potentially leading to a three-tier structure in the lineup: Foldable, Pro, and Air.
What Undercode Say:
The upcoming iPhone 17 Air isn’t just a hardware update—it’s a bold shift in Apple’s strategic direction. By pushing a 5.5mm profile into a mainstream flagship device, Apple is testing not just design boundaries, but consumer expectations around durability, weight, and value.
From an engineering standpoint, achieving such thinness while maintaining battery life, structural rigidity, and heat management is no small feat. This suggests Apple has either made significant strides in component miniaturization, or the Air model may feature sacrifices in battery capacity or camera technology compared to its Pro siblings.
Financially, the \$900–\$1000 price point places the Air between the base model and the Pro Max, likely targeting customers who want a premium aesthetic without needing all the Pro-level hardware. In marketing terms, it fills the gap between fashion and function — a niche Apple is uniquely positioned to dominate.
Leaked schematics, supply chain reports, and insider insights all point toward a broader realignment of Apple’s iPhone portfolio. The annual update cadence starting with iPhone 18 Air in 2026 indicates a new permanent fixture in the iPhone family — possibly even the start of a sub-brand under the iPhone banner.
From a product lifecycle angle, Apple’s strategy seems clear: Air becomes the lifestyle product, Pro continues to serve high-end tech users, and Foldable targets early adopters and niche enthusiasts.
What’s especially intriguing is the long game: revisiting the 6.9-inch slim prototype in 2027 shows Apple is not giving up on the impossible—just waiting for the right materials and structural engineering breakthroughs to make it possible. Titanium frames? Graphene batteries? New OLED flex tech? All could play a role.
If the rumored 2027 iPhone 19 Air really does bring the 6.9-inch slim form factor to life, it would mark a symbolic moment for Apple: the culmination of over a decade of thinness-focused R\&D. The delays may even help generate hype akin to the original iPhone launch cycle.
From a competitive perspective, this is also a move against Samsung’s Galaxy Z Fold lineup and upcoming ultra-thin models from brands like Xiaomi and Honor. Apple isn’t trying to catch up—it’s setting the pace again.
Overall, the iPhone 17 Air may be one of Apple’s most consequential devices in years—not because of what it does now, but what it will enable for the future.
Fact Checker Results:
Ming-Chi Kuo and Bloomberg’s Mark Gurman are both well-regarded Apple analysts with high credibility.
Multiple sources confirm the 5.5mm thin chassis, although hands-on images have not yet leaked.
The 6.9-inch slim prototype was reported in March 2024 by Bloomberg and aligns with Apple’s trend of secret prototyping.
Prediction:
Apple’s new iPhone 17 Air will likely shift the baseline for what consumers expect from mobile phone design. Expect ultra-thin phones to trend again across Android competitors by 2026. If Apple delivers on the structural integrity concerns and maintains flagship performance, the Air line could become Apple’s next “MacBook Air moment” in mobile — combining minimalism with mainstream appeal. The likely revival of the 6.9-inch version in 2027 would not only show Apple’s long-term commitment to thin devices but also reset the standard for premium smartphone design.
