After several weeks of using (and loving!) my N810, I have a question regarding the battery.

I used to have a Zaurus, and I found that I needed a battery every year or so. With the N810, the battery life is amazing relatively to my Zaurus. A the end of the day, if I am using the gps, I am at between 33 and 50% battery remaning. If I don't GPS, I am usually between 50 and 75% battery. When I go to bed, I plug the N810 in to power.

My concern is whether this is good for the device. I don't know what the actual charging cycle is, but when I got it, it charged in < 2 hrs. I have been plugging it in when I go to bed, and letting it charge all night. I am concerned that I am overcharging it that way. But I am concerned about being sans charge, and you can't take a snort off of USB.

What do you old Nokia heads do about charging? Is it bad to charge overnight?

Thanks,
