Just because the iPhone is still the world’s best-selling smartphone, that doesn’t mean its sales can’t be disappointing relative to expectations. Reuters reports that iPhone manufacturer Hon Hai, which trades publicly as Foxconn, reported a 19% decline in revenue compared to a year ago. What’s more, Reuters says that the decline is due primarily to “disappointing” iPhone sales over the past quarter and notes that revenue from building iPhones and iPads typically account for at least 60% of Foxconn’s sales. Recent estimates have suggested that Apple’s (AAPL) iPhone 5 has been selling below expectations but that the company is still in line to meet or exceed overall iPhone sales targets due to the continued strong demand for iPhone 4 and 4S models.
