Battery status not showing (even with correctly patched ACPI)
Use ACPIBatteryManager.kext 1.81.3 or later:
https://github.com/RehabMan/OS-X-ACPI-Battery-Driver
Also, if you installed on APFS, disable the trim patch.
With ACPIBatteryManager.kext 1.81.4 or later, you can also increase the FirstPollDelay (default 4000ms) by using RMCF (see SSDT-ACPIBATT.dsl in the ACPIBatteryManager github) or by using kernel flag abm_firstpolldelay. For example, to set to 16000ms (16 sec), use kernel flag: abm_firstpolldelay=16000
