The much-awaited Google Maps for iOS 6 debuted recently and reports suggested that the adoption rate of iOS 6 increased due to the release of Google Maps. However, latest reports indicate that the increased adoption rate of iOS 6 was due to the release of iPhone 5 in China.

Online data analytics firm Chitika Insights claims that iOS 6 adoption rate in the U.S. and Canada has seen no significant increase after the release of Google Maps app for iOS 6.

"Thursday, December 20th marks the first full week of Google Maps' availability in the Apple App Store. To determine the impact of Google Maps on iOS 6 adoption, Chitika Insights conducted a research study analyzing the trend in adoption rates since the applications' release, along with mapping the OS' adoption rates since its debut on September 19th, 2012 for added context. Following Google Maps' release, Chitika Insights observed iOS 6 usage remain fairly flat from midnight on December 13th to midnight on December 17th 2012," noted Gabe Donnini, Data Solutions Engineer at Chitika.

The iPhone 5 went on sale in China on Dec. 13 and more than 2 million units were sold just during its first weekend.

Jim Payne, CEO of MoPub, previously indicated that iOS users were holding on to upgrade their iDevices to iOS 6 until Google Maps was available on iOS 6. However, MoPub's findings were based on global data analysis and not just for the U.S. and Canada.

Chitika Insights reported that adoption rate of iOS 6 reached 50 percent in the first week of its release and gradually increased to 60 percent during the next three weeks. The iOS 6 adoption rate in the U.S. and Canada increased further with the release of the iPad mini and iPad 4 in November, but remained flat at 71.5 percent in the week after Google Maps was released.

It should not come as a surprise that the adpotion rate of iOS 6 has increased due to high sales in China as the country is one of the biggest economies in the world and accounts for a major chunk of Apple's overall revenue.
