Yes, it depends on the device, but we have demonstrated power
savings for two different types of devices using two different
measurement setups performed by two independent groups. Some
of the measurements are available on the website, the second
set should become available "soon" (but we can already say that
for the scenario we measured, the savings are in the same range
as before).

Yes, that's largely the point.

Well, that's not quite what the API would allow, especially as it
is obviously hard to predict that a different network will become
available.
