Leaked images purportedly show the iPhone 17 Air's 2900mAh battery, housed in a steel enclosure similar to the iPhone 16 Pro. The ultra-thin 6.6-inch phone, expected to be around 5.55mm thick, is anticipated to have the shortest battery life among iPhone 17 models, though likely sufficient for daily use. Apple's iOS 26 includes new battery-saving features, but the thin design is expected to impact battery performance. The phone launches in a little over a month.
