Summary: Warning about low battery level wrongly sums up

Screenshot of the popup in question
I have an older Thinkpad with two batteries. When they get low on charge (e.g.
5 % in each), I get a warning popup, but that popup sums up those 2 × 5 % to 10
%. This is a logical error, because if I have two batteries at 5 %, the total
charge is still 5 %. Especially when the two batteries have the same capacity.
The hover information of the battery symbol in the panel shows a different
percentage.
OBSERVED RESULT
Percentages are summed up.
EXPECTED RESULT
Percentages should be averaged, probably taking into account the capacity of
the batteries. I.o.w. I have an additional big external battery with 76 Wh and
the internal one has 23 Wh. If the external is at 5 % (3.8 Wh) and the internal
is at 10 % (2.3 Wh), then the percentage amounts to (3.8 Wh + 2.3 Wh)/(76 Wh +
23 Wh) = 6.2 %.
