According to the Global web index, Xbox One users spend the most time playing video games. They looked at users between the ages of 16-64, this is what they found:
When we asked 17,990 console users how long they spend console gaming each day, it was the Xbox One and Nintendo Wii U users who dedicate the most time to this activity, clocking up a daily average of around 2 ½ hours. PS4 users then fall slightly behind on 2:15 hours, something which is particularly notable given that it tends to outscore the other next-gen consoles for both current ownership and future purchase consideration.
