Apple Inc. reported its fastest quarterly revenue growth in more than three years, easily topping Wall Street estimates, after demand picked up for the iPhone and products in China.

On Apple's Q3 earnings call, CEO Tim Cook fielded questions on tariffs, smart glasses, AI investment, and its lucrative Google search deal.

During the company's fiscal third quarter, which ended on June 28, Apple posted a little less than $44.6 billion in revenue from its iPhone business, a 13% increase from the previous year. Those iPhone sales helped Apple reach total revenue of $94 billon, another June quarter record for the company, and a 10% increase from last year's sales.
