Apple’s iPhone 5 overtook Samsung’s Galaxy S3 to become the world’s best-selling smartphone model last quarter, according to new numbers from Strategy Analytics.

The iPhone 5, which launched in September 2012, shipped an estimated 27.4 million units worldwide in the last quarter, capturing an impressive 13 percent share of the global smartphone market, the research firm says.

The Galaxy S3 – which had been the best-selling smartphone the previous quarter – shipped 15.4 million units, slipping to third-place behind both the iPhone 5 and the earlier iPhone 4S (17.4 million).

“Apple’s iPhone 5 and iPhone 4S together accounted for one in five of all smartphones shipped worldwide in Q4 2012. This was an impressive performance, given the iPhone portfolio’s premium pricing,” said Neil Mawston, Executive Director at Strategy Analytics.

“Global demand for the Galaxy S3 appears to have peaked and Samsung will surely be keen to introduce its rumored Galaxy S4 upgrade in the coming weeks to fight back against Apple’s popular iPhone range.”
