It sold 47.4 million iPhones in the second quarter, 35 percent more than the same period last year and more than double from four years ago. iPhone sales in China too, more than doubled to USD 13.2 billion.

In total, iPhone sales contributed USD 31.4 billion, a 59 percent rise over last year, owing to an average USD 100 increase in their prices.

"The gap is widening between us and our competitors," Apple Chief Executive Tim Cook said in an interview with the newspaper, the Wall Street Journal.

iPhone, Apple's flagship product, represents more than 60 percent of its sales. The company's revenue also rose 33 percent to USD 49.61 billion. Analysts had predicted per share profits of USD 1.81 and revenues of USD 49.43 billion.

The company did not share information on the sales of the Apple Watch, which they recently began to sell, although Cook said it exceeded internal expectations. The gross margin of the company's profit was 39.7 percent, as opposed to the expected 38.5 percent to 39.5 percent.

Apple shares, however, fell 6.7 percent in after-hours trading at Wall Street, owing to what analysts called gloomy projections for coming months.

The company forecast revenue of USD 49 billion for the third quarter ending in September, against analysts' expectations of USD 51.13 billion.
