Is it bad to leave the phone plugged in all the time? So I don't really need my phone at work, and I have a spare charger from my old Palm Pre that I keep at work to charge my phone. I keep it plugged basically all day.

And at night, I keep it plugged in.

Admittedly, music and heavy screen time/data use during my bus-commute makes me need to charge often, but should I unplug after the time it takes to charge?

Does the GNex just stop using the battery and switch to direct AC power, like my laptop? When my laptop is full, it indicates: "Plugged in, not charging" meaning the battery is charged but it's drawing power from the grid and the battery is on standby. At least, that's what I assume my laptop does. I hope my Gnex is the same.
