New Leak Reveals Crucial Design Details

The highly anticipated slim phone that’s rumored to come to the iPhone range this September (colloquially called iPhone 17 Air) is slowly sliding into focus. A new leak reveals the battery capacity and its weight.
Apple’s iPhone 17 Air could have good and bad design news.
Surely, you say, the weight isn’t that important, is it? I’d agree, except when the phone is predicated on being super-slim and therefore super-light, it matters.
A leaker who regularly posts about the supply chain, yeux1122, has now commented in a blog on Naver about this.
In a machine translation, this is what was revealed. “The content about Apple iPhone 17 Air weight thickness battery capacity came out. (@Checking the credibility of the source of the parts company in Taiwan) iPhone 17 Air (mass production confirmed potential sample) 5.5mm thickness, Weight around 145g, 2800 mAh battery,” they said.
The thickness tallies with many other reports and, if true, confirms that the iPhone 17 Air will be thinner than Samsung’s just-released Galaxy S25 Edge, which clocks in at 5.8mm. Both these measurements exclude the camera bump.
The weight is impressive, around the same as the iPhone 13 mini (141g). It means that even if it only has one camera, as has been predicted, seeing and feeling the iPhone 17 Air will make it really stand out.
The battery size is intriguing. As pointed out by 9to5Mac, this is a battery size Apple has used before. “The battery capacity of 2800mAh isn’t necessarily surprising. That places it around the same battery capacity as the nearly five year-old iPhone 12 and iPhone 12 Pro, both of which shared a 2815mAh cell in a 6.1-inch form factor. Neither of those phones had stellar battery life, but it certainly wasn’t terrible,” it says.
And there have been recent reports that with the battery optimization predicted for iOS 19, Apple could make that size battery work harder than ever. Even so, “That means iPhone 17 Air will have a roughly 20% battery reduction from a standard iPhone, and roughly 40% from an iPhone of a similar screen size,” 9to5Mac reckons.
However, the leaker has more. “P.S. For additional batteries, there is a possibility of installing a high-density battery in the size of a 2800 mAh cell (actual capacity 15% 20% increase),” which could mean the battery life will be much closer to what you’d find in the iPhone 16.
