1. Run PS or TOP while in offline mode and see if anything is using a ton of CPU time.
2. My second action would be to go offline most and then for next 30 minutes run a cron tab every couple seconds and logs it in a file. Then go through the file looking for anything that is using a ton of CPU time.
3. Add a cron job that runs a scripts every couple minutes that does a "ps" (with whatever options you want) and then look at the log it creates and see what is "eating" the cpu time. In the morning look at it. )
One of those should show you the culprit... Could be something that is trying to activate every so often that is getting in a weird loop when offline. For example; the MicroB browser doesn't clean up all its processes when it is closed.

[The following question is to everyone besides Nathan, b/c he has already stated that he doesn't care]
Does Modest and/or the WLAN(for auto-connect) continue to check even in offline mode?
Everything else looks normal.

maybe metalayer-crawler? I know that it tends to hang and send sleeping tablets to death, especially when you linked "/" from your "/home/user/MyDocs/" folder..
@wesgreen: I never turn off my tablet at night and without using it I get over a week of standby-time in offline-mode.

So it must wake up and look around for WiFi every so often.
But I get at least several days of battery in idle.
Is your battery a year or more old? Has it been deeply discharged a few times or more?

Two suggestions:
1. Modest might have an impact on battery drain. I switched to Claws, much more powerful, and deleted my email account on Modest. (AFAIK it is not possible to un-install Modest using App Manager.)
2. Are you using an SD-Card with your device?
I have an N800 and tried two Kingston 8 GB Class 6 cards for a while. They would also drain the battery overnight with no WiFi on.
Since I switched to two Sandisk 4 GB Class 4 the battery lasts for at least a week with no WiFi.
Maybe just take the SD card out for a few days and see if it helps.

It did it again last night, after I went in and renamed metalayer-crawler, changed modest checking from 5 mins to half hour, and disabled auto wifi-search.)
I have to believe that it is a result of random tinkering.
Also, as per Nathan's advice, I ran top and nothing stood out as using the cpu too much (although maemo-launcher has an asshatload of instances running.) Otherwise, nothing looks very suspect.
So, I shall try this.
I will post back after a couple days with the (almost) bare install.
... and I have one class 4 Kingston 8gb microsd, but I still boot from the internal 256, so I'm not sure how it could be the culprit.
Thanks.

I was also contemplating on re-flashing my tablet due to some stuttering when opening certain programs( Canola2 would barely work at all) as well as feeling like the Extended Battery isn't giving me all it should. as far as I know you just hook it back into the PC for the same OS2008 install like I did when i first got it correct? well let me know how it works for you and I also am going to have to "manually backup" my data ... let me know your progress ( cuz if your like me I'm dreading it because I have so much on it now its gonna be awhile to get it up to par )

I had claws for a bit but wasnt able to get it to work for me ( didnt understand how to sync my gmail, and yahoo mail ) if you have any knowledge you wouldnt mind dropping my way on this matter I would love to use claws.

Alright, well I just took it off charge, leaving it in offline mode to see how it fares.
I reflashed last night, I have bare minimum installed, running claws mail (i like modest better), so no checking in the background.
Reading 10 days, 7 hours right now.

All times are GMT. The time now is 08:49.
(I googled "aaargh" and this was the best one I found)
OK, so here's a good one.
With wifi on, Modest checking emails frequently, my AIM, GTalk, and SIP accounts enabled, I get anywhere from 5-7 hours of battery use, depending on how often I touch the screen.
However, in OFFLINE mode, with nothing running (whilst I slumber), the battery is completely dead by the time I wake up in the morning!
Here's my average day:
I use the tablet as described above, mostly as an incoming communications monitor (of course, using for other things randomly). Then, I get home and it is usually in need of a charge, so I plug it in. After already being on charge for several hours, I take it off the charger, put it into off-line mode, and goto bed.
The end.
What is happening to my 10 days idle time? And more importantly, what is happening during this "idle" time that is killing the battery faster than when it is in use?
