I recommend that you talk to your friend about his (behave). is not unusual for teenagers of your generation to be attracted to computer games and the online world. But (spend) too much time online is unhealthy and makes it very difficult to focus on other things in life. Some students even become (addict) to the Internet and cannot concentrate school and family life. I think you should encourage your friend to try new (hobby). Why not discuss the problem together?

Is it all right students carry smart phones all the times? The opinions about that varies from person to person. Those for that think it is convenience for them to contact others, especially it is necessary in emergency.
Those like that, however, think students are not supposed to. In their opinion, some students can't resist a temptation to play games and watch something improper for them at improper time, wasting their precious time they should spend studying and taking sports. Besides, to playing games may cost them too many. As far as I'm concerning, students should value their studies, and safety more than other things. As for relaxation, we would better do what is beneficial for both mind and body.
