So, my old Surface Pro 4 (sadly I discovered this only few days ago) has a UEFI control option to “Enable Battery Limit Mode” https://docs.microsoft.com/en-us/surface/battery-limit
This seems to be keeping my battery at 50%.
I would like to ensure, this option would be built in from the beginning and not a later update.
I don’t know if original V, had that option?
Thanks!
