I think the problem with this phone is that its not ur everyday phone. its more of a computer!! N i cant keep my hands off it..so all these things drain the battery..but on average i can get thru a day. If i use it constantly meaning listening to mp3s, browsing on 3G n skype plus IM then 4 hours...

most of my mates who have N900 n dont use it much get like 2 or 3 days!!! but dats cos they havent realised ita full potential

I think the thing that kills the battery is MULTI-TASKING!!! if we couldnt multitask we wouldnt be on the phone so much!!
