The 9 to 5 workday schedule drives most smartphone usage patterns

Average time per hour for each of the five top smartphone functions rises sharply until the 9AM to 10AM hour when messaging, browsing, social networking, and gaming enter a late morning plateau.

The plateau exception: mobile voice calls. Average time per hour continues to increase until noon, when it sags slightly over the lunch break, and then accelerates again to a 5PM peak.

Both mobile social media and mobile gaming see a slow increase in their average time per hour for Arbitron Mobile smartphone panelists starting with the 1PM and 2PM hours, respectively.

The late afternoon hours of 4PM and 5PM mark a significant inflection point for smartphone usage patterns among Arbitron Mobile panelists in the United States.


    --  Starting at 5PM, the average time per hour for voice calling falls off
        sharply. At the same time, average time per hour for mobile gaming and
        social networking begins a sharp acceleration toward their respective
        peak hours of 9PM.
    --  Messaging begins a slow decline at 4PM that continues until 9PM. It then
        begins a sharper decline in average time per hour that goes on into the
        after midnight hours.
    --  The end of the workday exception: mobile browsing, which maintains a
        consistent average time per hour from 10AM through 10PM. As prime time
        wanes, browsing then declines at a slightly lower rate than other top
        smartphone activities.
    --  Mobile gaming and social media activities accelerate between 5PM and 6PM
        to their hourly peaks in TV prime time. Around 10PM, the average time
        per hour for gaming and social networking begins a steep decline that
        continues into the early morning, when the workday-based cycle begins
        again.
