Apple is predicted to launch the world's thinnest new premium smartphone on September 9, 2025, at just 5.5 millimeters (mm) in depth compared to 5.8mm in its most direct competitor the Samsung Galaxy S25 Edge.
The iPhone 17 Air will indeed win the battle of the ultra-slim frames on that day, according to a new and comparative new leak posted to X by the leaker @Jukanlosreve.
The 17 Air is also now allegedly confirmed to be just 145 grams (g) in mass as opposed to 163g in the S25 Edge, although that might be because of its much smaller ~2,800mAh battery.
Surprisingly, the 3,900mAh S25 Edge is projected to be the shorter device of the 2 at 158.2mm, compared to 163mm in the 17 Air, even though the latter might have the smaller display at 6.6 inches in diagonal length.
The 6.7-inch S25 Edge might also have the higher resolution of the 2, with a 3,120 x 1,440 panel compared to the 17 Air's 2,740 x 1,260 ProMotion screen - at least both will support 120Hz refresh rates, according to leaked slides allegedly originally belonging to the Korean carrier KT.
Finally, the Samsung device might be narrower as well, at 75.6mm compared to 77.6mm in the 17 Air.
All in all, the S25 Edge might in fact be the more compact "beyond slim" smartphone of the 2 in real-world use, slight delta in girth notwithstanding.
Then again, the 17 Air is now also believed to have a 128GB base model in addition to the 256GB and 512GB SKUs it might have in common with the S25 Edge.
The new leak seems to indicate that the 17 Air will have just 8GB of RAM, whereas the S25 Edge has 12GB.
The new Apple device might not be light on the wallet despite all that, starting at 1.4 million Korean won (~$1,010) in this leak.
Its Samsung rival was no less pricy on its launch, although it is currently available for as little as $699.99 on Amazon right now.
