I've got my N80 since back in may sometime. I'm not sure if the battery life has gone to hell since, but nowadays the phone -won't- last a full day. Here's my phone's day, in general:
~5 webpages in the Web app (that's the "full" browser)
1-2 hours of talk.
I check the calendar a lot and use the Autolock software, so there's a lot of locking-unlocking-screensaving on/off-and such.
10 minutes of gaming
15 minutes of music.
No wlan.
And then the phone dies at 20:00-21:00-ish.
I mean, what the f**k is up? All the "features" of this, my dream phone, are more or less unuseable, because then it won't last till i get home.
I use 3G/UMTS, and my new apartment's got dodgy reception, maybe that's what's eating my batt up? And no, I can't switch 3G off, since my GSM coverage is crapalicious. I think; I don't really want to test that.
Further, a second battery won't cover it, because a Symbian phone takes about a minute to boot up, and so I'd have to buy a desktop battery charger stand, and it will all add up, and suck. And I don't want to switch battery in my phone just to get by the last 4 hours in the day.
I'm hoping for Nokia to release a -much- better battery for it, or I guess I'll just have to get another phone when my subscription ends... in a year! =/
If I'm lucky 3 in sweden will have some ?bercool phone available by january, since i could then extend my subscription with them and get a new phone.
