During the first several months of 2014, the average American spent two hours and 42 minutes per day on their mobile device. So what did they do with all that time? A new survey breaks it down: 86% of smartphone use was accounted for by apps, while 14% was spent on an internet browser. People spent 32% of the time playing games, 17% of the time on Facebook, 3% of the time using news apps, 1.5% of the time on Twitter and 9.5% of the time using social messaging apps.
