I just got a full 4 days out of my new N73 - which I'm very impressed with by the way. What's with that? I've seen a N80 bum out in 8 hours with heavy use. Ok, ok - I switched it off for about 6 hours of sleep a night - but still.
I have a feeling this goodwill of mine will end as soon as I talk to someone who has had the balls to try out the N95 :)
