Tracking mobile web traffic, NetMarketShare computes the market share for mobile operating systems. Based on the data from last month, Android was able to widen its gap over iOS globally. Considering that the Apple iPhone 6s and Apple iPhone 6s Plus weren’t launched until September 25th, the recently released phones accounted for a miniscule part of the data. The new models won’t have a major effect on the results until the figures for this month are released.

According to NetMarketShare, Android’s global market share was 53.54% last month. That was up sequentially from August’s 52.14%. At the beginning of this year, Android has 47.45% of the world-wide smartphone market.

For iOS, September was the worst month since April. Apple finished September with a 38.58% slice of the global smartphone pie. That was down from the previous month’s figure of 40.82%.

Windows Phone also lost ground in September. The market share of handsets using Microsoft’s mobile OS declined from August’s 2.60%, to 2.48% in September. The new Windows 10 Mobile OS is expected to rollout sometime this quarter.
