Just picked up a new 2020 MacBook Pro 16" and I have it plugged in but the charging percentage is decreasing so what gives ?
I believe that is the new battery management thing. I noticed that on my 2020 13 inch MBP, while it's plugged it, it would go down to 90% and once its down there, charging kicks up. I turned this feature off as I do take my laptop out with me to work on daily basis so I don't need this feature when I'm using my battery. If it was sitting on the charger 24/7, this would be handy.What is the battery percentage? I noticed on mine the other day (system was pretty much idle) that the battery dropped from 98% down to 95% with the charger plugged in. I assumed it was some battery management system that is preventing the battery from sitting at 100% the whole time. Happy to be corrected if I am wrong.
