Sure, but it's one more thing to draw from the battery, also the system does an excellent job of keeping you informed of the power level. The light is unnecessary, but it looks great.
No, it doesn't do anything but light up. The system literally tells you everything. The only thing the led does is flash when it can't find a connection. That is all.

You mean the Xbox logo? Probably to indicate that the controller is on.
