Today, I looked at a research paper from 2010 entitled The Challenges in Large-Scale Smartphone User Studies. These researchers recognized the pervasive presence of the smartphone in the recent decade, and they wanted to look at the use habits of Blackberry users. The application was a simple logger (pictured below) that would maintain data based off two hardware cues: the LCD screen being activated and the OS idle flag being set.

Two main statistics were taken, with the results being shown in the below graph. The total length of interaction time per day ended up with an average of almost 1.7 hours, and the average number of sessions per day was around 87. Both values were skewed by high outliers, and (according to the researchers) also affected by malicious users and resource-hogging apps.

Thanks and gig 'em!
