Hi, either all this information is misguided or 90% of n900 users have faulty units other than the wifi. I have had the 7 hour problem, since I have now tested it by doing the following-
uninstalled all apps
removed all widgets
deleted one desktop
disabled gps totally
not even tried to active any internet since switch on (so no wifi at all)
enabled gsm only, so 2g only
after this i have sent 40 sms, made one 15 minute call an thats all i did, it was totally idle an it still only lasted 16 hours, this is totally unacceptable (oh an have brand new sim card) and I want some-one to personally prove to me they are getting more than this cause i dont believe a word of it, that or like i said the majority are having problems so nokia have really screwed up an will receive alot comin back!!!! cause mine will be.

If I've offended anyone I apologise but after all the fuss of waiting three months for it I'm beside myself with it now that i dont believe that i have a device that it ment to be perminant 3g, perm gps an perm internet connection an theres just no chance at all less ye dont want a portable device ye just want a wire sticking out of it plaugged in all the time, whats the point?!?!?!?
