What is the difference between Android System and Android OS ??

I'm guessing you're looking at the battery use screen?

I think the answer is that they're both part of the overall Android Operating System, but the OS is more the core OS processes, and system is a bunch of more "peripheral" processes. If, on the battery screen, you tap on the Android System row, it will show you a list of all the components that are included. It's a long list.
