so, my n900 barely lasts 10 hrs on 1 charge. i thought "hey, maybe it's b/c i had widgets x, y, z running" so i wiped everything and started from scratch (PR1.2), yet i still have the poor battery life. i have bluetooth and wifi on, but even then 10 hrs of standby, no talking, seems a bit poor doesn't it? i haven't installed ANYTHING at all, and am using Nokia Messaging as well as skype and gtalk. is the battery covered by the warranty?
