San Francisco: The ongoing trade-war between the US and China has caused Apple's iPhone production costs to rise as much as 3 per cent because of the new retaliatory tariffs imposed by Beijing.

"Tariffs on the device's Chinese-made batteries and other components would increase its manufacturing cost by 2 per cent to 3 per cent," Fortune quoted a Wedbush analyst Dan Ives as telling investors.

To recoup the same profit on each iPhone sold as before, Apple would need to increase iPhone prices by a similar amount.
