Android Duration Crediting Rule now aligned with iOS Duration Crediting - Digital Ratings (Monthly) - August 2016
As of August 2016 Digital Ratings (Monthly) data, a recent metering and crediting enhancement now enables improve​d reporting of mobile usage on Android devices. This involves removing a legacy crediting rule​ globally​ that​ capped usage at 30 minutes. This legacy crediting rule was designed to prevent attributing a gap in measurement as a long duration event. Also known as the "30 minute cap" rule, this limits the amount of usage reported for extensive periods of mobile activity. Nielsen has now aligned the duration crediting rules for Android to that of iOS. As a result, all duration related metrics across both web and app have shown an increase from August 2016.
