The price gap between iPhones and Android phones is growing larger. Despite Apple's introduction of the slightly cheaper iPhone 5C, the average iPhone selling price was more than twice as high as the price of an average Android smartphone in 2013.

This year, the expected release of the larger-screen iPhone will likely further increase the price difference between iOS and Android phones. While Android phones are becoming cheaper and cheaper, the larger version of the iPhone 6 will reportedly be sold at a $100 premium, which could push the average price gap to $403, according to an IDC forecast. These numbers explain why, despite dwindling market share, Apple remains the largest profiteer in the smartphone industry.
