That would actually be a good test

Apple Itouch is approx 7 hours streaming full screen video (barring the buffer issues it has )

but a comparative test would be to stream the video to an n900 with the cellular disabled, but then the n900 on the latest firmware cant stream upnp video now can it

I *may* try it tomorrow as im doing wireless training for the next 2 days so an ideal environment

You can't compare it to any other hardware, too many things are different, screen, brightness, content, format, etc etc. Still

I know, but it would be an interesting test nonetheless

I install large scale wireless for a living and we have just rolled out 900 Itouches to one place and they have a couple of niggling issues which appear to be buffer related but you cannot change anything at all on the itouches

Occasionally though we get to recommend the wireless devices the customers want

When I tested on n810 and n800 I could not measure any difference in power consumption. Theoretically 100mW is about 37mA. The n800 and n810 consume about 350mA streaming audio over wifi. So the radiated power by wifi is about 10 percent of total power use. I guess a 9 percent gain is worth something, but not much compared to range reduction.

maybe it is strange but when I change 100mW to 10mW i cant see any skype contacts online and when I change it to 100mW everything is ok again.

I can seee mine, i recently shifted this mode as all my battery was being drained out by the Wi-fi..
