Kind of an odd question, but I listen to XM on my X while I'm at work. This obviously drains the battery pretty hard, so I wind up just hooking it via USB to my work computer all day. So in total my phone is charging around 16 or so hours a day.
For the long term battery health, would it be better to let it discharge more or just keep it plugged in?
