While in Mophie, S6 appears to be charging when plugged in, but it loses power instead.

I use any charger, including the "fast" charger that came with my phone and most of the time that it is plugged in, the battery loses power at a fairly rapid rate, not increases the power. It does not happen all the time, but about 70-80% of the time. I am plugging into the Mophie.
