So just an FYI though once again, MS is stupidly short on detail…
There is a new version of the surface management extension in the store as of yesterday. One of my engineers got an email from an MS engineer that it has "significant improvements to smart battery management "
We are trying this morning to see what’s changed, though on the four systems (including mine) that we’ve installed it on so far, two of them now have the heart icon on the battery indicator and two of them that had them now do not, but instead show, on my system anyway, battery at 76% and that is is charging to 100%.
Obviously, they tweaked some things, but it’s unclear if it’s better, worse, or just different.
