Same problem here. Even when the N800 is off, the battery goes of.
This happens after upgrading to OS2008.

I noticed that this is tha case if I do the following:

1. If I turn of the N800 when it is not pluged in, no problem.

2. If I turn off the N800 when it is pluged in, and then plug it off, the battery goes off over night. I have the feeling that this is the problem.

I am seeing a problem with the battery as well. I recharged over night. In the morning, it did say that it was full. I went the day with little/no use. This morning, the battery was down a bar with 3 hours left. Under 2007, it would take me 3 days of normal use to get to that point.

Could someone point me to the information about incompatible wifi settings? I had recently installed a new router because my old one was locking up 2/3 times a night.

Heres an update to my previous post saying that my n800 was going through endless reboots while recharging. I left the IT without the battery in it overnight because I figured at least I could keep the IT from draining the battery over night. Well, the next day I was able to leave it charging and it had stopped rebooting while being charged. So, I wonder what the link is there. I didn't do anything else that might have caused that change.

I tried Neil's suggestion last night -- just took the battery out for a minute and put it back in instead of the whole night though -- and now my unit displays 'battery full' again
