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?
Something else to look into is that macbooks sometimes just hate having things plugged into USB when they’re sleeping. If you’re leaving anything plugged into the ports while it’s sleeping, try not doing that and see if it helps.
Can confirm - my practically brand new 2024 MacBook Air will happily drain its entire battery within a day or two while in sleep mode if I leave my usb hub plugged in (Anker hub connected to external mouse, keyboard, and HDMI to a second screen)
