The study by JDSU found that iPhone 5S user gobble up seven times more data over the study's benchmark iPhone 3G in developed markets and 20 times more data in developing markets.
Apple smartphones and tablets accounted for six of the top 10 most gluttonous devices with the inclusion of the iPhone 5C, 5, and 4S and the iPad 3 and 4.
“For the past three years we’ve seen explosive growth in mobile data usage, causing operators to have to wrestle with the challenges their success is creating,” said Dr. Michael Flanagan, CTO of Mobility for the Network and Service Enablement business segment of JDSU and author of the study.

Users of Apple's 4th generation iPad ranked themost data-hungry among tablets, consuming almost 40% more data than last year’s hungriest device, the Samsung Galaxy Tab 2 10.1.
The study also found that the new iPad mini is also "mini" when it comes to data consumption, consuming 20% less data than second- and third-generation iPads.
“Last year, we were surprised to see that smartphones trumped tablets when it came to data consumption. Lost ground has not been made up by tablets, in spite of the progress of the fourth generation iPad. Only two of our top ten most hungry devices were tablets this year, compared to three last year," said Flanagan.
