Validas shares even more interesting tidbits from its study in a blog post, especially in terms of sheer year-over-year growth in wireless data usage between 2009 and 2010 across all the major U.S. networks. Verizon lead the pack in terms of growth with a mean increase of 48.2MB to 147.2MB used per customer per month, as 42.9 percent of its customers opted into new data plans versus 33.4 percent a year ago. T-Mobile followed with a data usage increase from 44.6MB to 120.6MB, though it had virtually no growth in the number of new data plans. Sprint was in third place with an actual decrease in mean data usage of 166.5MB to 133.4MB, even though new customers opting into data plans increased from 36.9 percent to 49.9 percent.
AT&T came out on top with the greatest number of customers with data plans at 71.2 percent, which was up from 58.4 percent a year ago. Mean data usage per user is also up from 111.9MB to 149.6MB.
Validas did not present any explanation for the significant growth in wireless data usage from Verizon Wireless or other network smartphone users. One possible reason: the fact that Android allowed users to run data-intensive third-party apps in the background -- such as Pandora or turn-by-turn directions -- while iOS did not during the time of Validas's study. The restrictions that Apple had to impose on some types of features due to AT&T's struggling network may be another cause. Apple also pitches the iPhone to a broad audience that may contain a higher ratio of members who simply do not want to consume as much data while on the go. Android, by comparison, got to the market more quickly for power users who have been waiting to live on streaming music, portable 3G hotspots, and a mobile OS that can be more easily tinkered with.
However, because the iPhone only recently began allowing third-party apps to run in the background with Apple's release of iOS 4, it will be interesting to see Validas's study performed again in another six to 12 months.
