Nielsen’s Q4 report revealed that the iPhone 4s, which was launched last year, became a very important factor in trying to close the gap between its biggest market competitor, Andorid. From a 28.3% it has risen to claim 30% of the US market share of the 60% smartphone users. The reason behind it is that, according to survey, 44.5% of new acquirers chose the iPhone and 57% of that said they chose the iPhone 4s. This shows how much of an impact the iPhone 4s had to those wanting to a shift from feature phones to smartphones. Still the OS, Android had the most acquirers in Q4 with 51.7%.
The graph below also shows that Android has also increased from 42.8% to 46.3% of the total market share in the US. Though Apple has been slowly catching up, it is not because Android is losing market share but that other OS’s, notably RIM’s Blackberry, market shares are dwindling down. Windows Phone seems to have been picking up on the market share as well from a measly 1.2 in Q3, it has increased to 4.6%.
