With the popularization of 4G communication technology, the proportion of smart phones in the market is also increasing. As a result, the majority of users are increasingly inseparable from smart phones, and college students, who often walk in the forefront of the trend, are most affected. According to the survey of MyCOS Research Institute, 82% of college students believe that they have mobile phone dependence, and the average daily use of mobile phones is 5.2 hours.

The survey report on the use of mobile phones by Chinese college students also shows that 14% of students use mobile phones for between 7 and 9 hours a day, while 13% use mobile phones for more than 9 hours. In addition, students use mobile phones after 6:00 p.m., but 79% of college students use mobile phones in class. Boys mainly use mobile phones to browse news and entertainment (watch videos and play games) in class, while girls mainly use mobile phones to shop in class.

Interestingly, 24% of the respondents said that mobile phones play a positive role in classroom learning, such as searching for information and assisting learning.

This survey is only aimed at domestic college students. It is believed that the phenomenon of playing with mobile phones in class should be less common in middle schools. However, for the author, who is used to browsing information on mobile phones, the average daily use of mobile phones should be more than 9 hours. The latest research from the University of Los Andes in Chile shows that the average score of students decreases by 0.3 points when they use mobile phones for an extra hour every day. Therefore, students should try their best to reduce the time spent using mobile phones.
