Abstract: By using physical activity level scale and university student cellphone addiction tendency scale, the au-thors investigated and studied totally 700 current university students at 10 universities in Guangzhou Higher Educa-tion Mega Center, and probed into the mutual relationship between physical exercise and cellphone dependence of university students. The results show the followings: (1) university students’ physical activity level was at the me-dium and low levels, mainly embodied in low physical exercise intensity, short exercise time, low exercise fre-quency, and low exercise volume; male students’ physical activity level was significantly higher than female stu-dents’, arts students’ physical activity level was significantly lower than science students’; (2) university students’ cellphone addiction tendency was at the medium or higher level, their degree of cellphone dependence was univer-sally high; male students’ cellphone addiction tendency was significantly lower than females students’, arts students’ cellphone addiction tendency was significantly higher than science students’; (3) there was a significant negative correlation between physical activity level and cellphone addiction in university students, there were significant dif-ferences in cellphone addiction tendency at different physical activity levels and its scores at various dimensions; the cellphone addiction tendency of university students with a exercise volume ranging from zero to medium showed a declining trend, however, there was no significant difference between medium exercise volume and high exercise volume; (4) except for the prominent behavior, both population statistical indexes and physical activity lev-els can significantly predict university students' cellphone addiction tendency; in which, gender indexes significantly and positively predict cellphone addiction tendency, physical activity levels significantly and negatively predict cellphone addiction tendency. This research indicates that physical exercise can effectively reduce the degree of cellphone dependence of university students, and that physical activities with a medium exercise volume can sig-nificantly improve the phenomenon of cellphone dependence of university students.
