I can confirm that turning power on on wlan0 does actually save a lot of
energy, but ...

Hmm, here I do see a difference, I am not sure, hard to test. I left it
running the same way for about 10min and then the usage was mor or less
the same.

BUt it is anyway good to know that turning power on amounts to more or
less the same as turning the device completely off, at least for me.

Thanks

Best wishes
