iPhone owners spend 50 percent more time using their phones than Android owners, according to new data from Experian, which sampled 12,770 American smartphone owners.

In a rather frustratingly small graphic, Experian also breaks out the key activities across all smartphone platforms by popularity, frequency and time spent. The larger the bubble, the more people who engage in that activity, ranging from talking at 79% to reading ebooks at just 0.5%.

What’s notable is that, despite oft-heard concerns about smartphones proving socially isolating, with people interacting more with their phone than the people around them, the most popular activities are social ones: talking, texting, email and using social networks. Much web usage is also likely to be social.

The company also released a graphic comparing the time spent across a range of both devices and conventional media.

The comparative time spent using tablets and PCs seems to suggest that while tablet sales may soon outstrip those of PCs, the true post-PC era is still some way off, with over 12% of Americans using their home PC for at least 20 hours a week against less than 2% for tablets.
