When I first got my Nexus One, I remember that as soon as I disconnected the charging cable (whether it be USB, Car, or Home) the little green/amber light would disappear right away. Then, I noticed it's taking longer and longer to shut off. I just unplugged it now and the light stood on for a couple minutes before it went out. Anyone else experiencing this? Also: I know it's not an actual issue since it doesn't affect any functionality, but I'm worried this is a sign of a bigger problem to come.
