What do people use their smartphones for the most? Users in 10~20s use it for communication, music and video, those in 20~30s and 30~40s for web search and games, respectively.  

Usage of smartphone and mobile contents varies by age group. First of all, 20-something users stay on their smartphones the longest - 281 minutes a day - among all age groups, followed by the groups of 9 and under, 30-something, and 40-something. The contents used were different by age group too.

In case of mobile games, contrary to expectations that those in their 10~20s would use their smartphones for games most, those in their 30~40s were found to play games with their smartphone the most.

In case of communication services (e.g. Kakao Talk), music and video contents, users in their 10~20s spend far more time in such contents than other age groups. Those in their 20~30s spend more time in web/portal contents than other age groups.
