Smartphone owners spend more using platforms such as Twitter and Facebook on their devices than any other online activity, and are also considerably more social than their desktop counterparts, reveals a new study.

A July 2012 study by GfK Group discovered that almost one-third (31 percent) of the average smartphone owner’s internet time is spent social networking – close to twice as much as email, which ranked as the second most-popular activity.

On desktops, social media and email both tied for first place with an 18 percent share. Video, search and gaming rated as the other favoured internet pastimes for both smartphone and PC owners.
