Apple introduced its thinnest-ever iPhone, the iPhone 17 Air, at 5.6 millimeters thick, according to Bloomberg. The Air, priced to replace the iPhone 16 Plus, includes the A19 Pro chip but lags in battery, camera, and audio performance compared to other models. Apple introduced a Pro iPhone with two terabytes of storage priced at $1,999, featuring an aluminum unibody, an upgraded camera system, and a new vapor chamber cooling system. The tech giant also launched new smartwatches and AirPods while keeping most prices steady. Apple is trying to maintain interest in its smartphones, its biggest revenue source, amid slowing demand, market saturation, and tougher competition in China. The company has also lagged in artificial intelligence and foldable phones, adding pressure to prove it can still innovate.
