A new survey sugests that iPhone is no longer the data usage champ.

AT&T (T) and Apple (AAPL) will tell you until they are blue in the face that the iPhone uses more data than any other device in the history of mobile communications. That’s why there has been all the fuss about an over-saturated network causing dropped calls..
A study released today by Validas seems to refute those claims, however. According to their findings, the average data consumption for non-Blackberry Verizon (VZ) smartphones was 421MB per month, compared to the 338MB per month consumed by AT&T iPhone users. It wasn’t even close! Their methodology:
Our 2009-2010 Wireless Data Consumption study examines, analyzes and compares information drawn directly from actual consumer bills from 2009 and 2010. It provides year-over-year trends and detailed distribution charts segmented by device and by carrier, providing unique insight into the explosive growth in wireless data, which carriers are benefitting most from it, and which user and device groups are most driving it.
While the study didn’t specifically call out Verizon’s line of high end Android phones, there is really nothing else in Verizon’s line that would make such an impact besides the multimedia-heavy Droids. Who else would be using so much data? Windows Mobile? Symbian? the Pre? No way – in fact, I’d say that the Droids were even pulled down by these devices. They didn’t include Blackberry devices in the study because of the way they compress data.
The iPhone won’t be catching up to Verizon’s Droids anytime soon either. Verizon said last week that the new Droid X phones were using 5 times the data as any other phone they’ve carried. On the flipside, AT&T recently put new data caps on its users which should slow their data uptick overall.
Will Apple and AT&T continue to be able to use “unprecedented data” usage as an excuse for poor iPhone performance if Verizon and its Droid phones are pushing more data without the same issues?
