I’ve got a 2.9 GHz 6-Core Intel Core i9 Macbook Pro (yes, the one with the touchbar and the keyboard nobody likes)…
Anyway, it’s been working great, aside from this issue which seems to happen on occasion, when I don’t keep it plugged in overnight. It will just drain real fast sometimes.
What causes batteries to just drain over the course of an hour or so?
Except its showing the screen wasn’t on during those hours
The second one is the relevant one. You have to allow the computer to sleep when the display is off or it will still stay awake and drawing power when the display is off.
It’s meant for laptops you want to run in a closed position with an external display when plugged in.
