BEIJING, July 31 (Xinhua) -- Mobile reading was the most time-consuming behavior among Chinese mobile internet users in the first half of this year, a report showed Tuesday.

Chinese mobile internet users spent an average of 39 minutes each day reading and 34 minutes watching videos and social networking in H1, according to a report from mobile internet big data analytics Trustdata.

The report showed that of the 70 million respondents, about 26.4 percent of Chinese mobile phone users spent about two to four hours each day on their smartphones.

Tencent's instant messaging tool WeChat was the most popular mobile app in terms of the number of monthly active users.

With a robust community of daily active users, Meituan continued to dominate the food delivery market by making up 59 percent of total market transaction volume in H1. The company unveiled a platform to promote autonomous delivery services last week as part of its efforts to leverage high-tech delivery technologies to improve efficiency and reduce costs.
