Re: Severe battery issues with N900 (not your usual moan!)
 

Something is not ok on OS level guys, I keep 3G always on...

Do you use apps that constantly use a network connection? Like the weather widget FaceBook, or the email app?
I must admit I only sync when I want to read my email and I don't keep instant messaging on at all times either, I use pidgin...

Either way my device lasts a day and 1/2+ with moderate usage (30min calls, 20 emails syncs, 1hour+ of web browsing and about 40 minutes fm transmitting.
That's on a work day; If I've got spare time to play around and check the repo's it dies @ ~12 p.m.
