Glad to hear you worked it out - good to know those items in any case. I suppose the next step would be to file a bug with those projects, possibly with an strace (I think?) result to find out what they're doing when not being used.
When adding these bugs to bugs.maemo.org Bugzilla, please add the "use-time" keyword to them so that they're easier to find.
I have not yet had the same good luck as you and get about 1-2 days even if I turn the thing to offline mode when I don't want to use the internet.
You can strace multiple processes at the same time. Attached is a script that helps a bit in that.
I'm suspecting the continually breaking email (it must not like my imap server or something) might be affecting it, since I already removed the fm radio and load meter bits.
There's already bug 3022 on FM-radio.

RE: battery estimates, I remember reading not too long ago on some really clever analysis of battery discharges in some GNOME software, possibly Gnome Power Manager? It might be useful/interesting to see if that logic can be ported, because from at least a theoretical math point of view it seemed pretty sensible.Ryan Giacomo Tufano wrote:Battery problem has been solved. I had 1 critical issue and 2 minimal ones on battery life. First and worst was pidgin. The software is very aggressive when the net goes down. RTComm beta is more 'quiet'. I use it ever 'on' autoconnecting when network is up. Pidgin, apparently, don't like this approach. Gnotifier also seems to be a battery eater, much less than pidgin. Last problem in my home network. I have 2 apple ap in a wds network (concrete building). If the tablet is left in the middle between the two ap, this seems to hamper battery life. No special ideas on the why. Just noticed it. I'm now happy again, with ca. 4 days standby with moderate use. I was just willing to share my findings in case someone else is hit, many thanks for your support in debug this. Tx, gt ps: the last strange thing is that the battery applet says: '8 days', goes down one day per day up to 4 and, then, the day after is empty. Not a big problem, in reality. Battery indicators are, in my experience, not more reliable in other cases (phones or notebook).

Another possibility is some process using network often. Could you try using "Offline mode" option from the power key menu? If it helps significantly, then the issue is related to network.Have you enabled RSS updates? Do you leave e.g. Browser window open when you don't use the device?No (I hate programs polling automatically) :-). The only program polling is the gmail notifier...What applets you have enabled in Home?Internet search, web link (no change on standard URI), Tableteer info, clock and Internet Radio (never used, sitting idle).If you do following from SSH after screen has blanked: strace -p $(pidof hildon-desktop|cut -d' ' -f1) Is there any activity?I got (very fast) after the command: gettimeofday(whatever) = 0 ioctl(3, FIONREAD, [0]) = 0 gettimeofday(whatever) = 0 poll( and then nothing else... To answer your question in a later email (so to try to save bandwidth): the device is not in R&D mode... It was before the upgrade, but I disabled the R&D mode after an email from you a week ago, or something like that explaining the problems with power management in this mode. Thinking about this, I did two things: upgraded the OS AND disabling R&D mode. But I think the latter can't be the problem, no? btw: I disinstalled Canola (the program is very complex, it is a candidate for problems/bugs). I'll try (in this order): leave the tablet "as is" (to test canola); if nothing leave the tablet with net disabled; if nothing I'll try to kill the metalayer-crawler (but I had no problem before, on N810 or on the 770 I used before this one and this tablet used to have power for 4 to 7 days)... If nothing the only other thing I can do is to reinstall OS2008 and, then, add an application every 2-3 days to isolate the battery offender... If there is something else I can try, feel free to suggest other option (I'm open). :-) If there are no other suggestion I'll post a success when I found the root cause... Thank you all for your help and support, gt
