Americans spend an average of 58 minutes a day on their smartphones, with talking and texting accounting for about half the time, a market research firm says. Smartphone owners devote 26 percent of the time they spend on their phone talking and another 20 percent texting, a blog post by Experian Marketing Services reported Tuesday. Social networking and browsing the mobile web combined to account for 30 percent of the average American\'s daily smartphone use, it said. The rest of the daily time was spent on emailing, playing games, taking pictures with the phone\'s camera and using its GPS location capabilities, Experian said. iPhone users were ahead of the Android-using counterparts in daily phone usage, spending an hour and 15 minutes each day on their devices, 26 minutes more than the typical Android phone user.
