I'm just wondering if there's a correlation with firmware version.

Powertop works for me. OSSO_VERSION='RX-51_2009SE_1.2009.41-10_PR_TRUE'

Control panel applet says "1.2009.41-10" on my device.

Hi Andrea,

I've been using the N900 since last Saturday as my main mobile phone and
messaging device and for some light browsing and blog reading. I use the
"always on" Internet connection option and while I'm in the office the
N900 frequently switches between Wifi and Edge (no 3G here in the middle
of nowhere). I also installed quite a few apps and I use all the virtual
desktops. So far the battery has usually lasted between a full day and
one and a half days. Compared to what I've seen some of my friends
getting out of their iPhone batteries and what I've read in the Palm Pre
reviews - since the 3GS and the Pre use the same CPU - I think getting
about thirty hours out of the battery is not too bad. Much less with
moderate usage looks like a problem with the battery to me.

Cheers,
Kai

What widgets do you have on the desktop? RSS? Facebook? Foreca?

Thanks in advance,

I have the calendar and Facebook widgets on the desktop. And since the
last reboot (yeah, there are still some stability issues ;-)) two days
ago the Email, Messaging, RSS, Phone, and Internet apps are open.

Cheers,
Kai

Simply re-run it again.

It then worked for me.

Hmm, Skype and apps like that might suck quite a bit of battery,
depending on how chatty they might become in their idle states. Knowing
a bit about Skype from monitoring a large company network, especially
when it does not get a connection or an unreliable connection it tries
to connect to the next Supernode very often, at least once a minute.
Wireshark might help you to find out how "chatty" your N900 is...
If I have some time over the weekend, I could run some tests with
Wireshark and Skype/Foreca/Facebook and whatever else is usually running
on my N900 to see how often these apps actually send traffic in their
idle states.

Cheers,
Kai

it would be great!

Anyway, here is the result of powertop execution on my N900:

I hope it can help you to understand what's happening :)

Hi

p.s: my N900 was connected to charger during this test... do I have to
disconnect it before doing the test?
