the tMBP in my sig has had major battery issues since upgrading to High Sierra. With my typical workload and settings, I could squeeze somewhere between 8-9 hours before getting to about 5%. In High Sierra, that is basically in half with a similar workload. I went from 100% to 60% in two hours with very little going on. Screen @ 25-30% brightness, few tabs open in safari (I even have an adblocker that blocks annoying ads with video) Evernote & Byword open. Not much else beyond that. Does anyone else have issues like this (on any machine?). Does the .1 update resolve this issue?
