I have had some sort of problem with battery discharging on my MBP after shutting down fully from Windows. I can't use sleep/hibernate on Windows at all because it crashes upon restarting, with a kernel panic that is reported to Apple next time I start MacOS. That seems to have to do with initiating the Touch Bar. Things are fine when sleeping or shutting down from MacOS, but three times now I have shutdown from Windows and disconnected from power, then the battery is almost fully discharged (1-2%) when I turn on the computer less than 24 hours later. I don't understand what might be happening while it is fully shutdown.
