Thanks for all feedback.

After Christmas break I started with fresh 2008 installation and trying to
install more and more applications and find suspect with combination of
strace/htop.

thanks

 A process waking up very often can also be a problem as it doesn't
 allow hardware to sleep[1], but if it consumes very little CPU each
 time, you don't see it in top.  Strace can find those out, see:

 [1] For CPU, even a badly coded program shouldn't be active more often
 than at several seconds intervals when it's not doing anything for
 the user. Network access should happen *much* more infrequently
 (say at max 1/2 min interval even in badly coded program)

  Pick a binary, any binary.
  There, you found it!

 Yeah - when my idle N800 2007.whatever  lost all charge in
 an afternoon, it turned out to be some task running a
 constant 3% CPU. Top (or htop, if you have it) is worth a look
 to check for such things.

hildon-desktop eats 25% cpu when animating new mail. The new mail animation
started happening after i installed and configured modest

Battery Life N800 + OS2008

2007-12-21 Thread Piotr Zagorowski
Hi,

I know battery life topic was brought to this forum, but now I'd like to ask
about new OS2008 and battery life. I have noticed significant decrease since
I moved to OS2k8. I didn't ask before as I was waiting for official release.
Now I can confirm this is issue (in my case). Running on OS2007 I could use
my nokia for about 5 days. Now it last for about 1 day and I have to
re-charge.
I know CPU works faster and this means more power as well as there are more
improvements etc etc.  Is this only one explanation? I usually try to close
all applications I don't need when not using my tablet.
Does anyone experience the same problem? Maybe this is coincidence and my
battery/charger is broken? However it charges and  everything looks fine.

thanks

Pit

P.S. I really appreciate new OS. Most applications I use is already ported.
Everything is much faster and apart from my battery life concerns it looks
fantastic. Very well-done Nokia!

Hi,

I have experienced exactly the same with os2008beta. I also began
wondering if my battery began to wear off signiricantly. I have just
installed the current os2008 and will see how it affects battery life.

Cheers,
Martin

This is the state of things:
- during development we test all the common expected usecases with the
stock fw
- we make sure that the claims we make on the advertisement material and
in the box are backed by corresponding reality
- the last number i saw were pointing to above 20 days of standby idle
(meaning that you charge the battery and let the device untouched for 20
days) even if we officially support about 10, iirc
- the higher frequency does _not_ affect negatively the use time unless
you are doing something cpu-intensive

I would suggest you to do like others have done before: try without any
extra application, then proceed by bisection, by installing half of
those you have now and see if there is any significant decay of battery
life.
