The iPhone maker's share of the worldwide smartphone sales market rose to 14.6 percent in the quarter from 12.2 percent a year earlier. Rival Samsung Electronics Co Ltd's share fell to 21.9 percent from 26.2 percent, Gartner said on Thursday.
Global smartphone sales grew at its slowest pace since 2013 at 13.5 percent to 330 million units in the second quarter of 2015, impacted by declining sales in China, research firm Gartner said today.
Worldwide sales of smartphones to end-users totalled 329.67 million units, an increase of 13.5 percent from 290.38 million units in the same period in 2014, Gartner said in a statement.
"While demand for lower-cost 3G and 4G smartphones continued to drive growth in emerging markets, overall smartphone sales remained mixed region by region in the second quarter of 2015," Gartner Research Director Anshul Gupta said.
Emerging Asia/Pacific (excluding China), Eastern Europe and Middle East and Africa were the fastest-growing regions, driven by good performance from Chinese and local vendors, he added.
By contrast, smartphone sales in China fell for the first time year over year, recording a four percent decline.
