Apparently this was taken to mean the simple arithmetic mean, and not the weighted average (by the capacity of each battery). http://bazaar.launchpad.net/~indicator-applet-developers/indicator- power/trunk.15.04/view/head:/src/service.c#L1316 shows: const double percent = sum_percent / n_batteries; This means that if one battery is twice as large as another, then after that battery is discharged, 50% would be reported. I'd expect 33%. The code needs to be fixed to reflect the more precise use of the word "average". <https://wiki.ubuntu.com/Power#multiple-batteries>: "Their percentages should be averaged, weighted by the capacity of each."
