Battery status 100% fully charged

Hello,
I am using a new lenovo laptop with windows 10 pro on it (not OEM).
I have calibrated my battery because it's status was "100% plugged in, charging".
Now after calibration, when it reaches 100% the status is "100% Fully charged", but I think the battery is being charged non stop because it doesnt go under 100%.
I believe this is not healthy for the battery so Im looking for a way to get the "100% plugged in, not charging" status. can I configure it through windows?
Thanks
