iPhones made up four out of the five best-selling smartphone models over the past three months, Kantar Worldpanel said today.

iPhone 6 is a hit

Huge iPhone 6 sales mean Apple should deliver record smartphone sales this quarter, even as recent data suggests the company's customers are the only ones who shop for things using their device.

The latest Kantar Worldpanel ComTech smartphone sales data for the three months to October 2014 shows that the iPhone 6 has increased Apple's sales share in almost every major market.

Dominic Sunnebo, strategic insight director at Kantar Worldpanel ComTech, said: “Apple has experienced a huge jump in sales share across almost all major markets thanks to the launch of the iPhone 6. In major European economies, the US and Australia, Apple’s share of sales has risen."

UK goes Apple

Apple's success is particularly evident in the UK, where the company has managed to seize its largest ever slice of smartphone sales ever, with 39.5 percent.

"Most of these sales were driven by loyal Apple users," said Sunnebo. "Some 86 percent of British buyers upgraded from an older iPhone model, only 5 percent switched across from Samsung.”

Apple's US sales rose by a more modest 0.7 percent in the three months ending October 2014 versus the same period a year ago.
