Mobile phones started life as machines built for talking – but actually making calls is now one of their least popular functions. Smartphone owners now spend just 12 minutes talking on their phones a day – but spend two hours using the gizmos. Texting – formerly one of the reasons people became addicted to phones – is now less popular, with users spending just 10 minutes sending messages. In terms of time spent, British users spend more time surfing the internet, checking social networking sites, playing games and listening to music. The study of 2,000 smart phone users marking the launch of the Samsung found we spend almost 25 minutes a day surfing the internet.
