The battery drain from the update 12.1.4 is unacceptable!!
Also it happen to my macbook with update 10.12.6. 🙁
I have done everything you can do to improve the battery even BEFORE these updates like background app refresh off, location service off, icloud off ect ect.. (you know all the lists online of things you can do)
and then bam… a new update and the battery is destroyd, so now what? can you unstall it?
Do I never buy apple again? what to do?
Im so done with these battery destroying updates every year!
