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?
If your computer is less than five years old, Apple will replace the battery for around $100 at any Apple store.
2024-2018=6 years booo
Might be worth calling to see if they’d still do it. I believe it’s subject to service part availability after the five year mark.
