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.

Apple reported strong iPhone sales and rebound in revenue from China, giving a much-needed boost to two parts of the company’s business that had struggled over the past year.

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.
