+1, androidauthority only had about 4hr 25m screen on time, so the 9+hr seems unreal, they probably turned off GPS and cellular, which sucks up the most juice.
There's a difference between 9 straight hours of use vs. 4 hours of use with periods of idle time between uses. The Note 4 exhibits drain in standby so it's only natural to expect lower screen on time when large periods of idle are experienced.
