Good to hear someone else is seeing the same thing. After low battery warning almost 24 hours back, my N800 is still going. Battery level has been bouncing between 30% and 37%. It drops from 37 to 30 and then climbs back up to 35 or 36.

Yup, I noticed the same behavior too :(

I have an even simpler one : why do cards that worked just fine in a N800 with 0S2007 and OS2008-Chinook suddenly create all these random power-related problems in Diablo, and still do after six months and two updates ?...

just ran a test this am
connecting to my home wifi and running nothing other than connection manager and adv-power my battery indicator droppedd 6.8% in 5 minutes!
connection manager showed that my n810 received 1.85MB of data and sent .23MB of data. i have set modest to manually download email and i manually refresh my rss feeds- i don't get it
something is operating in the background while on wifi and it is not running while tethered to my phone.

Usually once a day right after you connect the download manager is checking for updates... That's at least 30 seconds on 70-100% CPU. There are probably other internet eating beasts on your tablet :)

I can't install the advanced-power applet cause it says I don't have python 2.5. WTF?

Is this EVERY time you connect to the network? At least 2 times a day I have to go into offline mode. Some days it's like 4-5 times? Are you saying each time I go online this thing checks?

That's not cool. I thought it checked when I asked it to. This will have to stop.

it has a 24 hour counter. it will check at first available chance after that count comes around.
that interval can be adjusted in gconf btw.

also, i suspect modest may not properly respect having the automatic check disabled:

Thanks tso. I don't mind once a day regardless of checking status but if it was each and everytime i thrown on the connection then that would be a problem.

I charge every night before I go to bed and leave my N810 on 24/7. I've only had one instance of mysterious low battery. I turn off my WiFi router wwhen I power down my system for the evening. With it off I occasionaly heard the the lost network connection sound. One morning the battery was very low. I now disaable networking as part of my bedtime ritual and the low battery in the morning event has never occurred again. My N8110 is my constant companion aaand assistant. I use it frequently for short periods as well as some longer use periods. The battery time estimate seeems to be based on battery consumption rate aat that time. After finishing a along period of use it may say 3 hrs but after a minute of idel it may say 5 or 6 hrs. For my useage patterns I consider battery life good. I don't have swap enabled aand the only timed event I'm aware of adding is a daily alarm to wake me in the morning.
