I am rather curious how some people, especially heavy users get good battery life. I get the kind I expected. If I stay at home with wifi, it's not empty at 22, but I slap in in the charger anyway. If I'm on 3g a lot I have to charge it at 18 or 19. I get up at 7:15, my day lasts about 19 hours.

Of course it depends on usage, but I'm a pretty heavy user. I'm always online with skype/gtalk/ovi and have witter updating every 15 minutes, 3 email accounts uppdating every 30 minutes, almost constantly chatting, messaging, mailing, tweeting, browsing, playing freeciv or the dig, reading and posting on tmo, chatting #maemo, listening to music, locally or on spotifty or streaming from my server. I talk on the phone for about 30m each day.

I'm actually pretty impressed that i sometimes get a whole day out of it. I find that battery life depends on net traffic, where traffic over 3g takes much more battery than wifi, and having device screen on eats a little. CPU doesn't affect it that much imo. GPS kills it fast.

I carry the charger adapter in my pocket, have a charger in my cars and have the original charger by the bed, and a couple of old nok chargers in other places (by sofa, by computer, at work), so I can charge the phone if I know I will be requiring lots of battery later.

I'm not sure whether you think this good or bad battery life, but it works pretty well for me, but it would be nice to not have to think about it at all, but I think that's a utopia with my kind of use.
