Haha. That's probably it. I waited all of 5 minutes (if that). I needed to head out the door so I figured I should charge the system so that it will be fully charged by the time I get back. Though, when I did get back, it was still clear. About 4 hours had passed until I docked again and actually played Zelda. I guess I'll wait longer next time.
You could be entirely correct with what you did. I was just curious if it was immediate or not. Since I docked mine I haven't taken it back out due to my case and screen protectors not arriving yet. I'm wondering now if the felt is the way to go for possible scratching or if it really does impact the heat distribution.
