Apple's iOS gains ground on Android in US as iPhone retains smartphone lead

Source: comScore

For the three months ending in May, Apple's iPhone grew its dominating lead as the top U.S. smartphone, while iOS gained ground on Google's Android, says research firm comScore.

According to data from comScore's MobiLens and Mobile Metrix services, Apple's iPhone accounted for a 41.9 percent share of U.S. smartphone users in May, up 0.6 points from a month earlier. Samsung also enlarged its second-place piece of the pie with a 0.8 percent change over the same period, ending with a 27.8 percent share of the market.

Out of the top-five OEMs, only Apple and Samsung managed to gain subscribers over the three-month period, with LG and HTC both shedding 0.3 points to come in third and fifth, respectively. LG left May with 6.5 percent of the market, while HTC managed 5.1 percent. Motorola held steady with 6.3 percent, coming in fourth.

Google's Android remained the No. 1 smartphone platform in the U.S. with a 52.1 percent marketshare, or 10.2 points more than Apple's iOS. The world's largest mobile OS showed no movement, however, meaning the iPhone's 0.6 percent increase came from less popular platforms like fourth-place BlackBerry, which lost 0.6 points in the three-month period.

Microsoft's Windows Phone came in third with no change in marketshare, while Symbian rounded out the top five with 0.1 percent of the market, down 0.1 percent from February.

comScore estimates some 169 million people owned smartphones in the U.S. during the May period, up 4 percent since February. Smartphones now account for 70 percent of the nation's overall cellular market.
