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. [unhandled content-type:application/pgp-keys] | |
