Just so you are aware, I came across this thread while having similar charging problems.. the N800 continues 'charging' for hours, and this is the same if I use my N770 battery in the N800.

So far today its been charging for 4 hours or so, while my E61 charge completed in its typical 2 hours..

Same problem for me with my n800 and os2008. If I put the battery on my n770, the charging is quick. After the charging in the n770, the battery is put in the n800 and is fully charged. So it's not a problem with the battery but with the os2008.

I think some daemon or background process gets stuck somewhere and puts the CPU at work thus draining the battery down.

Hi all, first post : be kind ;-)

Okay, my 2p... I had similar problems with battery life. Sporadic. Some days it was okay, some days it was dead by morning when it quoted there being hours left in the evening. I updated to the 2008 final (after using the Beta for a few days), and at the same time I removed the metalayer-crawler daemon as suggested in other threads (changed the name to "metalayer-crawler.disabled" and killed it in the process toolbar.) I have now got the device to last 3 days with maybe 2 hours a day surfing. I had "4 hours" left, but rebooted (to show a work colleage) and it went down to 2. The first time the battery gague had gone down since upgrading! Just recharged it in 2 hours back to full charge.

The side effect - the media player insists I have files that don't actually exist in my library - hmmmm... and can't seem to remove them (as in deleted already, but library is not updating.) Not a big deal. I guess I could run the metalayer-crawler once every time I add new files - at least then it is a known quantity!

Hope that helps someone ;-)

Welcome!

Ok - the other thing I do... I always go in to "offline" mode when I'm not using wifi and I always "lock screen and keys" when not in use. Without removing the metalayer-crawler, this did extend the life slightly, but now having removed it, things are a lot better.

N800 is possibly the best purchase I made this year! (lucky I got it in there before January!) Nothing else, since my iPod video in 2006, has made such a big impression. I'm extatic with it at the moment!

Just to let you all know, this bug (random battery drainage overnight) is known problem for Nokia developers. They do not know yet what is the exact mechanism how/why his happens.

So, if you have seen this, and if you have an idea why that might have happened, please post your findings/ideas to bugzilla.

I do not remember if there is a bug open for this yet? I'll check and post back.

EDIT: I did not find open bug for this? If nobody posts back I'll file a new bug soon.

EDIT2: Bug #2602 opened:
https://bugs.maemo.org/show_bug.cgi?id=2602

My n800 drains overnight without being on also since upgrading to the latest OS. It also goes through endless reboots while being charged. This happens whether it is on or off. It didn't do this for a while after I flashed with the new 2008 OS. Then after a couple hours of charging it started the rebooting cycles.

NS

I just upgraded to OS2008. I didn't notice any difference in term of battery life (yet..), but I did notice that instead of the usual 2 hrs. charging to get the 'battery full', now no matter how long I left the charger on, it would say only "charging".
