the tablet seems equally unhappy with the router with WPA off. i am beginning to wonder if its a router issue, it may not like the one its dealing with. if you are having the battery life issue, post up your router brand and model.

switching the router to "access point mode" fixed the problem.
my wifi router is hooked into my linksys router, and it may have been some firewall BS or something who knows.
anyways seems happy so far, WPA is on, Access Point Mode is on.

I think I read somewhere that Ad Hoc WiFi mode is extremely battery intensive - something about the radio not being able to sleep (and thus chewing up the battery). In infrastructure (access point) mode the radio can sleep as the access point will send out regular beacons to maintain the connection but allowing the client to sleep between intervals, and this behaviour isn't possible in ad-hoc mode so the 770/N800 WiFi radio is going full blast all the time whether it's got data to transmit/receive, or not.

update from me:
My problem was definitely the bad SD card. With the card out my idle CPU was low. With a bad card in the idle CPU was 80% and above. I am guessing that this would drain the battery overnight.
My SD cards are fixed now it seems and the battery issue is gone also.
I like my N800 again!

Something about load_applet_run is fishy.
I noticed that after installing and activating it on my n800 (latest firmware, running off mmc), that my battery would die in less than two hour standby with nothing running if the machine wasn't used.
When not allowing the device to go into standby, battery life was normal.
Removing load_applet_run fixed this for me.

What is "OMAP McSPI/0" by the way ? It seems to consume lot's of CPU time.
yesterday I removed a corrupt SD card from my N800 and thought that had stopped my bad battery life.
but! I had also bought a new router and set it up as WEP. Maybe my old one was WPA!
