A hand holding iPhone Air, front exterior, side exterior, Sky Blue colour, very thin profile, Dynamic Island, buttons: side, Camera Control The all-new iPhone Air is so impossibly thin and light that it nearly disappears in your hand. At 5.6 millimetre and weighing just 165 grams,3 it’s the thinnest iPhone ever — even with a large, immersive 16.63 cm (6.5″) display4 and the power of the A19 Pro chip. It’s a paradox you have to hold to believe.
