Apple's new iPhone 4S consumes on average twice as much data as the previous iPhone model and even more than iPad tablets due to increasing use of online services like the virtual personal assistant Siri, an industry study showed. When Apple rolled out the iPhone 4S in October, its small improvements disappointed many analysts and reviewers, but consumer demand for the device has been strong, and buyers have extensively used their devices.
IPhone 4S users transfer on average three times more data than users of the older iPhone 3G model which was used as the benchmark in a study by telecom network technology firm Arieso.
Data usage of the previous model, the iPhone 4, was only 1.6 times higher than the iPhone 3G, while iPad2 tablets consumed 2.5 times more data than the iPhone 3G, the study showed.
Today's generation of smartphones is placing increasing demands on available carrier bandwidth as applications become slicker and average personal usage of videos intensifies.
That sharp rise in data consumption puts more pressure on wireless operators to speed up capacity investments, as they are struggling already with clogged telecom networks to keep up with growing demand for data services on the go.
A smartphone's consumption of data depends upon what the user asks it to do. The iPhone 4S is perceived by some as a data hog because of Siri, a well-reviewed virtual personal-assistant and search app. It is integrated into the iPhone 4S and responds to voice commands.
