This infographic compiled by Guohead.com shows the behaviour patterns of Android vs. iOS users in China. While the data from 2012 may be slightly outdated, the general usage patterns seem to be still holding up today.
With the market share of Android being twice larger than that of iOS in China, marketers need to know what drives Android users to spend money on apps, as, those patterns are different from iOS users and vice versa.
For example, iOS users are 3 times more likely to make an in-app purchase than Android ones. This is hardly surprising given the fact that virtually all entry level low cost Chinese smartphones are Android based.
This infographic also gives an interesting overview of monetization models that would be more efficient for different systems. For instance, a free app with ads seems to be the highest grossing model on Android compared to other revenue models.
