Behind the scenes at Apple, engineers are fine-tuning a device that’s already generating debate: the iPhone 17 Air. According to recent leaks, this ultra-thin model could feature a mere 2,900 mAh battery, the smallest seen in a recent iPhone. Its 2.49 mm thick steel frame is pushing the limits of what’s technically possible. An impressive engineering feat no doubt, but it raises a simple question: what’s the point of such a thin phone if it can’t last a full day?

A striking comparison with the competition
The numbers speak for themselves. Compared to the Galaxy S25 Edge (3,900 mAh) and the iPhone 16 Plus (4,700 mAh), the iPhone 17 Air’s battery capacity is underwhelming. Even with iOS’s software optimizations, the margin for error is slim. Its nearly 7-inch display will draw significant power, meaning heavy users will likely need to recharge before the day is over.
Technical arguments with a somewhat mixed outlook
Apple is betting on a steel chassis, identical to that of the iPhone 16 Pro, to better dissipate heat and simplify maintenance. Precise soldering and new adhesives are said to allow easier disassembly. But these improvements seem quite minimal compared to the sacrifice in battery life. Early feedback from forums is unequivocal: “It’s a step backwards,” “Has Apple forgotten the lessons of the iPhone 5?”
Apple’s strategy raises questions. While competitors like Samsung have shown it’s possible to combine slimness (6.1 mm for the S25 Edge) with a decent battery, the Apple brand is taking a radical path. Who is this for? Aesthetes willing to sacrifice battery life for an ultra-thin device? Or nomads who will have to carry an external battery pack?
If the leaks prove true, the iPhone 17 Air could become a textbook case. Its likely high price will only increase the pressure. Battery life tests will be scrutinized closely. And user reactions in 2026 will say a lot about the market’s real priorities: the beauty of an object or its ability to keep up with us every day.
