Yes, what I observed was that the battery voltage climbed almost
immediately to Vsys (there are a few caps in the way that slow
this down, but it doesn't take long to charge them), and then
wait_for_power thinks it sees a healthy battery.

Yes, but isn't that basically what happened before as well, just a
few milliseconds later ? My question is if there was anything subtly
wrong in the functionality or if you just changed it for esthetics.
