On Christmas Day of this year, activations of new Apple's iOS and Google's Android devices surged 353 percent over the baseline (the average from the first 20 days of December) of 1.5 million to 6.8 million, and more than 142 percent increase over last Christmas, according to mobile application analytics firm Flurry.
Google's Senior Vice President (Mobile) Andy Rubin tweeted that 3.7 million activations Android devices were activated on Dec. 24 and Dec. 25. But Apple did respond to the activations data.
As about 1.1 million Android devices were activated on Christmas Eve, Android device activations would reach 2.6 million on Christmas Day, according to Apple Insider.
However, over 4.2 million iOS devices were activated on Christmas Day, Fortune's Philip Elmer-Dewitt said on Wednesday. This means iOS has a 1.6 million unit lead over Android.
Last week, Rubin announced that more than 700,000 Android devices were activated every day. Earlier this year in June, he claimed over 500,000 Android devices were activated every day.
How does iOS stack up against Android? In 2010, Apple sold 16.2 million iPhones and 7.3 million iPads in Q4. It is expected that Apple will sell as many as 2 times iPhones this year than last year, and sell more than 13.5 million iPads in Q4.
The company's iPhone 4S was released on Oct. 4, and its first weekend sales topped 4 million, and Susquehanna has forecasted that the iPhone 4S' sales will continue rising in Q1 of 2012.
