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?
As everyone else says, battery replacement time.
The freemium and excellent little macOS utility Coconut Battery gives details that will confirm why you need a replacement.
Thanks!
I repair macs and just hate the battery job on your model. It would be reasonable to have Apple do it. It’s expensive, but it’s a better quality battery than the third party stuff you get by DiY or going to an independent shop.
That said, it may be messy and time consuming, but you can buy the battery off of amazon and use iFixit to guide you, and save $150.
Does iFixit not sell that battery? If they do then I would recommend buying from them even if it is a little more expensive than Amazon so you help support right to repair legislation, not to mention supporting their repair guides, tear downs, etc. that benefit all of us.
Not in Canada last time I checked, but pretty sure they do in the States.
