xfce4-power-manager describes battery capacity incorrectly

[Peter-jezdec]

In my Power Information dialog, battery capacity is incorrectly described as having energy units:

Energy full design 4.5 Wh
Energy full 0.9 Wh
Energy empty 0.0 Wh

This can be confusing since batteries are typically rated in terms of how long they can supply current. A correct display would read:

Capacity design 4.5 Ah
Capacity 0.9 Ah
Capacity empty 0.0 Ah

If it is really the intent to display capacity in energy units, the values reported would have to be multiplied by the battery voltage, which is 12V in my case:

Energy full design 54 Wh
Energy full 11 Wh
Energy empty 0 Wh

However, since battery capacity is most commonly reported in Ah units, I think the best solution is to report capacity in Ah units rather than Wh units. And, to make the display look like the first one I proposed above.

I suggest that you upgrade to Ubuntu 14.10 and test the new xfce4-power-manager release (1.4.x). The calculation of the energy values may have been fixed in the meantime.

If this is not the case or if you still prefer Ah over Wh, please file a bug report on the Xfce bug tracker. Thanks in advance.
