CPU speed is throttled to low speed on battery power
July 7, 2022

Best workaround (so far) is to:
Download ThrottleStop and uncheck "BD PROCHOT".

Bad workaround is to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Intelppm
Change 'Start' value to '4' from the default of '3'. This disables SpeedStep, which means the CPU runs at full speed, and will use more power.
Note that this is for Intel CPU's, an AMD CPU has a similar registry key.

I tried all the other fixes listed here and none worked.
