Apple reports record iPhone 17 sales, calling it the "most popular ever." The announcement comes as CEO Tim Cook prepares to step down after 15 years leading the company.

Cook's departure marks a major leadership transition at Apple. The timing of the iPhone 17's record performance suggests the company maintains momentum despite the change. Apple has not named Cook's successor or announced a specific departure date.

The strong sales figures underscore continued consumer demand for Apple's flagship product, which remains the company's primary revenue driver. The result demonstrates the iPhone's resilience in a competitive smartphone market dominated by Samsung and other manufacturers.

iPhone sales strength typically reflects both hardware innovation and Apple's ecosystem advantage, which locks users into its services and devices. The company's ability to sustain growth in this category has historically driven overall financial performance and stock valuation.
