The relationship between smartphone use and students` academic performance

This study was designed to measure the impact of smartphone usage among college students on their current academic success. We report the results from a survey among 99 undergraduate student iPhone users in a large Midwestern U.S. university. The survey combines objective smartphone use time directly obtained from Apple's ScreenTime feature with official GPA and ACT/SAT scores from university records. We evaluate how GPA and self-reported measures of academic success are determined by ACT/SAT scores, demographics, school-related variables, study-related variables, socio-economic variables and time spent using one's smartphone. Our results suggest that one additional hour of phone use per day lowered current term GPA by 0.152 points on average. Time spent using a smartphone significantly reduces GPA and self-reported measures of academic productivity.
