i personaly dont but i find this odd.

Well. Now that we've handled that...

I have a bad habit of leaving it plugged in some of the day and most of the night. I use ORB and the internet radio a lot so the battery charge doesnt last. But I havent noticed any ill-effects/issues.
I wasnt aware that Nokia recommends NOT having the unit plugged in after the battery is charged.....thanks for this info.

I leave it plugged in all night, almost every night. What the manual says is odd. I would think that any modern electronic device with a lith ion battery would be able to shut off the charging mode. Even the software knows when it's full. Perhaps the tech writer was stuck in the 80s?

They don't like being left at 100% charge for very long. They don't last as long if you keep them at 100% forever. My PowerBook, for example, lets the battery move between around 95% and 100% if you leave the charger plugged in all the time. Once it hits 100% is stops charging it, and lets it discharge slowly on its own.
It's quite possible that the 770 only has a basic LiIon charger. It won't cause the battery to blow up or overheat, but it may shorten its life.
I don't, unfortunately, have any real idea how long it's 'safe' to leave the battery at 100% for. To some extent, I try to use it "reasonably" and just assume that its battery is a consumable.
I guess the real question is: If the battery is at 100%, should you unplug it, use it for 3 hours, charge it for 3 hours, or does that shorten the battery's life more than 6 hours at 100%?
