So, I updated to High Sierra today without any issues and it works smoothly so far.

I mostly keep my MacBook plugged in and occasionally unplug it to exercise the battery, so today after the update I took it off the charger and started using it for browsing. The battery went from 100% to 87% in an hour, and I'm wondering if that's normal after a new update?

My battery is very healthy, 97% health and has only 195 cycles after two years.
