Also definitely needs a changes file as this will change how hosts report battery.

For the query removal, are we able just push that because the mac/win battery query split isn't released yet? Or are there BC concerns?

@mostlikelee Let me know when this is ready and I'll provide approval for the contributing docs if needed.

LGTM. Fixed an "it's" that should've been an "its" so we're good to go.
