[[Cueball]] is reading the report from a smartphone app showing the average time each day that he was NOT looking at his phone during the hours he was awake this last week.  This is a reversal of the more expected behavior for a {{w|screen time|screen-time}} app, which would normally report the amount of time spent looking at the screen. The point is that as mobile phone usage becomes more prevalent, it may be easier to comprehend to report non-screen time.

People in the US spent an average of 24 hours of non-work/education screen time per week in 2015, compared to 10 hours of active leisure, according to one estimate.[[https://www.brookings.edu/blog/social-mobility-memos/2016/09/13/how-free-time-became-screen-time/ How free time became screen time]]  Averaged per day that comes to 3.4 hours screen time and 1.4 hours active leisure.
 
  
Screen time may be associated with various undesirable conditions, such as mental health difficulties like depression, decreased activity, reduced sleep quality and quantity.
 
  
 
In Cueball's particular case, if we assume that he is awake 17 hours a day (the average for most people in USA), then his non-screen time average of 2 hours 48 minutes means that he spent more than 84% of his awake time last week looking at a screen. This means that while his 6% improvement is positive, he still has quite a significant habit. His previous non-screen-time would have been 2 hours 38 minutes, so he has managed to shave 10 minutes off.  Increased screen time often comes at the expense of decreased sleep time, so it may not be fair to assume a constant amount of sleep.<ref>[[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5279707 Digital media use in the 2 h before bedtime is associated with sleep variables in university students]]</ref><ref>[[https://www.sciencedirect.com/science/article/abs/pii/S1389945717303507 Decreases in self-reported sleep duration among U.S. adolescents 2009–2015 and association with new media screen time]]</ref>
