(CNN) -- Think you use your phone to look at Facebook a lot? Unless you're doing it at least 14 times a day, you're actually below average.
That's just one of the surprising revelations in a research report by IDC released Wednesday. The study tapped 7,446 iPhone and Android users in the U.S. between 18 and 44 — representative of the 50% of the population that uses smartphones — and asked them questions about their phone usage across one week in March.
Depending on your perspective, many of the results are either depressing or confirm what you knew all along. For example, it seems that 79% of smartphone users reach for their devices within 15 minutes of waking up. A clear majority — 62% — don't even wait 15 minutes, and grab their phones immediately. (Among 18- to 24-year-olds, the numbers rise to 89% and 74%.)
Given that the survey was sponsored by Facebook, most of the questions focus on the social network. Which is, it seems, only the third most popular app on your smartphone, after email and the browser. Still, 70% of smartphone users are frequent Facebook visitors, with more than half of them checking it every day.
Peak Facebook time is during the evening, just before bed. But any time's good: on average, we visit the Facebook app or the site 13.8 times during the day, for two minutes and 22 seconds each time. Our average total daily mobile time on the site — and remember, this is just via our smartphones — is half an hour.
That's roughly a fifth of all the time we spend communicating; it's only slightly less time than we spend texting. On weekends, we check Facebook more than we text.
Any place seems to be good to check Facebook, too. Some 46% of us check it when we're shopping or running errands; 48% use it at the gym. Even preparing a meal gives 47% of us no respite from the social network. (Well, what else are you going to do while you're waiting for the microwave to ping?)
Perhaps the most unpardonable sin: 50% of smartphone users admit to checking Facebook while at a movie. We hope they mean only during the ads.
So what are we spending all that time doing? Well, for about half of that daily half-hour on the social network, we're simply browsing our News Feed. The rest of the time is divided fairly evenly between Facebook messaging and posting updates. Half of Facebook users play games via the service on their phone a few times a day.
