Europe study pinpoints iPhone 5 as the top mobile data hog, phones overtake tablets
It turned out that by far Apple iPhone 5 users in Europe were the biggest data consumers, using more than 50% of what iPhone 4S ones were chugging, which was also a record number at the time. As far as data generated and uploaded, head of the pack were people with the Samsung Galaxy S III, and largish devices like the Galaxy Note II are also making inroads as big mobile data hogs.
The other interesting trend is that for the first time smartphones took over tablets as biggest data consumers. With today's ever-increasing screen sizes, you can do much more with a phone now, and what you used to do on a slate, which somewhat explains why in the top 10 the first 6 are phones, next 3 tablets, and the last one a "phablet".
