In the PID activity list there are quite many "skyhost" prosesses, some
of which are quite active. Those may also keep the WLAN busy as the
wl12xx process is very active as well.

Skyhost seems to be a part of skype. Try disabling the Skype login and
see what the powertop says after that?

This test was done with these situation: connected to home wifi,
facebook ON, forecast ON, pressing sometimes the main menu to keep the
light always ON ---> http://pastebin.ca/1625155

This other test is the same as previous but without facebook and
forecast: http://pastebin.ca/1625163

Do you have RD-mode or RD-flags enabled?

Are you charging your device until the led shows green?

You know it, because you've got to enable it via flasher :)
So if you don't know, probably you didn't enable it :P

it replies: disabled

by the way: I've seen that connecting to Simyo UMTS/HSDPA (which is
ALWAYS in roaming, since it's a virtual operator and it uses Orange
network) it takes a lot of battery. If I keep connected to my home's
wifi, battery last much much more.

I'll be able to test with Italian 3Hg carrier once I'll come back in
Italy... but this will be for Christmas holiday :\

Phone side needs much longer idle network traffic periods than WLAN,
to be able to power down. It's best if you can track the network
traffic to find out whether something causes it to be always up
(some process in the device[1], traffic in the phone network).

93.75 hours.

I'm not going to repeat that test but based on my other tests, I would
guess that it wouldn't fluctuate more than a few hours.
