I did take that into account, and I miscalculated. Now that I am properly doing the computations to explain why I stated 150 hours (I intended with the new voltages in mixed use), I see that my mental sketches were too gross.
They stated 100hrs of video or 150 of "reading" (interpolated) with the old specs, which may become 133hrs of video or 300 of "reading" with the new specs. So it is more like, very tentatively, 200 hours of mixed use (60% active and 40% static or simply the geometric mean).

Duly: with an undefined average battery (3000mAh?), an undefined average board etc.

EDIT: Although I am not sure about how optimistically the board consumption was estimated: I guess I would already be impressed if a good board lasted for 50 hours of mixed use without a display attached, with a single charge...
