Apple’s thinnest iPhone yet? Here’s what we might see in the mysterious iPhone 17 Air this September

Apple could be gearing up for a major switch-up in its iPhone lineup this year. As we previously reported, the iPhone 17 series — expected to drop this September — might debut an all-new model: the iPhone 17 Air.

Think of it as the possible successor to the ‘Plus’ — but slimmer, sleeker, and potentially lighter. Rumors hint that the Air will bridge the gap between the standard and Pro models, featuring a larger display, an ultra-thin build, and Apple’s in-house 5G chip.

Details are still under wraps, but if the leaks are true, the iPhone 17 Air could be Apple’s boldest design shift in years — and the surprise wildcard fans didn’t see coming.

Here’s what we know (so far) about this mysterious new iPhone.

A design that defies the norm

One of the most buzzworthy rumours around the iPhone 17 Air is its incredibly thin form factor. Whispers suggest it could be just 5.5mm thick — even slimmer than the iPhone 6’s 6.9mm frame. If true, this would make it the slimmest iPhone ever made. The trade-off? Possibly a smaller battery. But the payoff could be a lighter, sleeker phone that stands out from the rest of the 17 lineup.

A single camera, reimagined

Unlike the multi-camera setups we’re used to, the iPhone 17 Air might dial things back with just one 48MP rear sensor — but don’t mistake simplicity for boring. The camera could sit inside a sleek horizontal bar, a fresh aesthetic move for Apple. It might skip fancy zoom tricks, but should handle everyday shots with ease.

More screen, less bulk

Even with its slim build, the Air is rumoured to pack a 6.6–6.7 inch display — larger than the regular iPhone 17, but not quite as massive as the Pro Max. Think: big-screen experience without the bulk.

Apple’s custom 5G chip inside

Under the hood, Apple may finally be ready to ditch Qualcomm (again). The 17 Air could feature Apple’s in-house 5G modem, capable of up to 4Gbps speeds — though mmWave support may be missing. Still, this shift could signal Apple’s long-term push toward greater control over its tech stack.

Powered by the A19 chip

Performance-wise, the Air will likely run on the standard A19 chip — not the Pro variant, but still plenty powerful for everyday tasks. This chip choice could also help Apple position the 17 Air as a more affordable alternative to the Pro lineup.
