Samsung loses smartphone market share to Apple in the US and to Xiaomi in China

42% of all smartphone users in the US had an iPhone in Q4 2013, while 26% owned a Samsung handset. In the same quarter of 2012, 35% of users had Apple smartphones, and 22% were loyal to Samsung. In conclusion, Apple’s market share grew by 7%, while Samsung gained only 4%. It’s probably safe to assume that the launch of iPhone 5S and iPhone 5C (both available since September) helped Apple a lot in the battle with Samsung.
According to Kantar Worldpanel, Samsung’s smartphone market share is also dwindling in China. Reportedly, Xiaomi dethroned Samsung in December 2013 as the most popular smartphone brand in China, helped by its affordable, yet well-equipped devices that are produced locally.
