I've been charging nightly to 90% for a couple of months. Ever since I saw Kim's video on the subject. Yesterday morning I got the 2019.5.15 update. This morning, I has warning message that said something to the effect that charging beyond my daily usage on a regular basis can degrade the battery. Has anyone else seen this message or understand what it means? I wish I had snapped a picture of it. If it happens again, I will.
