Thanks for the link, but its suggestions are pretty much the same old generic ones that are rehashed every time there's a battery issue and as general procedures between issues.
Unfortunately, though, it doesn't even consider the possibility of a Mojave bug, which seems a bit unrealistic in view of the number of people experiencing problems,
myself included. (I don't use my battery regularly, and my perception may be a bit off, but I"m definitely seeing a difference in its life expectancy.)
