In the three months ending November 2014, the impact of the iPhone 6 and 6 Plus launch continued in the run up to Christmas with iOS growing its market share in all surveyed countries except for Japan where performance in 2013 had been boosted by the addition of NTT DoCoMo as a carrier partner.
Across Europe, Android remained the dominant OS with a market share of 69.9 per cent, although this is 3.2 percentage points lower than the same period in 2013.
Kantar Worldpanel ComTech Europe, strategic insight director, Dominic Sunnebo, said Great Britain saw the strongest share decline for Android at 6.7 percentage points.
Apple's market share gain, triggered by the iPhone 6 and 6 Plus launch, continued into November when it reached 42.5 per cent of British sales for a growth of 12.2 percentage points year-on-year, mainly at the expense of Android.
Sunnebo said the longer the new iPhone models were on the market, the more their appeal would extend beyond Apple's loyal customers.
"For now, customer switching from Android to iOS remains stable at 18 per cent", he said.
