I have started having trouble with charging on my 800 if i plug it into an ac outlet it seems to drain the power however if i plug in to any computer it will charge but the life is only about 4 hours if i'm busy could this be a software problem??
That's a strange problem. Have you tried to reset the phone to factory settings? Could help in figuring out if it's software related. Is it the same on all ac outlets? I reckon it would be best to contact Nokia support on this one.
