Default Battery life doesn't make sense

OK, it's a given that we seem to get around 3-4 hours maximum run time when screen is on.
If this is the case, then how did the reviewers get almost 9 hours VIDEO playback???? It just doesn't add up. I don't believe that I can run a video on my One S with the screen on and have it go anywhere near 8 hours.... let alone 9.

According to GSAM battery - the phone consumes around 2.5 watts when running. The battery is rated at 7.75 watts. Which makes for 3.1 hours run time with the current screen brightness. This makes sense.

Has anyone actually got more than 5 hours run time watching video???

This may be one case of the AMOLED working correctly with darker areas. Apparently since most movies have lots of black, it doesn't use much power.
