Since updating my 2015 MBA to Mojave, I've been getting significant battery drain while the laptop is "asleep." I used to have minimal battery drain when asleep... I would maybe lose a couple % over 24 hours, but now it's usually around 20-30% in 24 hours! It seems like the computer often won't enter a deep sleep/standby/hibernation mode. I think it happens most often when I close the lid while plugged in... and then unplug the computer after it's already asleep (but sometimes it happens when purely on battery power as well). Interestingly, I noticed some changes in the "Power" section of System Report. I've never seen "High Standby Delay" or "Standby Battery Threshold" listed there before, so it seems like Mojave changed how standby behaves on my MBA. Is anyone familiar with what these new changes are or how I can go about restoring the old behavior?
