How much time is too much time spent on a mobile device? While that question may be hotly contested, most people would likely agree that 15 hours a day qualifies as too much. But a recent online survey says that high school girls in Japan spend an average of seven hours a day on their phones, with 10% saying they spend 15 hours on their device. In contrast, boys of the same age reportedly average about four hours of daily phone use. Smartphones’ function and convenience are constantly improving, and phone addiction is becoming a real problem. The surveyed group could probably use some helpwith being in the now. (Jezebel, Yahoo)
