According to researchers, the more minutes you spend on your phone the more likely you are to be depressed.
By using phone sensors and GPS data a team at Northwestern University found that they can detect people with depressive symptoms with 87% accuracy. Researchers also found that 68 minutes was the average daily use time of depressed individuals where the non-depressed were around 17 minutes.
Other factors for depression included time spent at home, visiting few locations, and varied work times.
