Apple Inc's iPhone sales fell for the second straight quarter, although the 15 per cent drop was less than feared.
The company's total revenue dropped 14.6 per cent in the third-quarter ended June 25, also declining for the second quarter in a row.
Apple said it sold 40.4 million iPhones in the third quarter, more than the average analyst forecast of 40.02 million, according to research firm FactSet StreetAccount.
Apple had reported a 16.3 per cent drop in iPhone sales in the previous quarter, the first decline since the smartphone was launched in 2007.
Sales of iPhones account for about two-thirds of the total sales of the world's most valuable publicly traded company.
