There's a bunch of studies that tell us that we look at our smartphones 100+ times a day. I got so tired of it, I am trying out a Pebble smartwatch to sort out relevant and irrelevant notifications at my wrist without always taking out that 5" thingy. But that just means that I exchanged screens, not changed my overall behaviour. This research here from Flurry shows that the number of people who launch apps 60+ times a day has doubled over the past year. Flurry's study includes 1.3 billion mobile devices (reportedly...), so it should be pretty accurate.
