If you upgrade a windows 10s license to 10 pro but only install apps from the store, will it have the same battery life? I am assuming that it will as 10s is full windows 10.
From what I've heard, it shouldn't make a difference until you start to install a lot of software which runs in the background and at startup. If you are able to have software which doesn't hog resources, then it shouldn't make a difference, I hope.
