Power notifications don't combine multiple batteries

[Kai Mast]

Related to #880881:

I have two batteries. One is empty, the other has 30 minutes left. I get notifications that battery status was "critically low" and that the computer will shut down soon.

Instead, it should only show this notification if both batteries have a very low status. The notification icon already seems to combine them correctly.

Kai, could you attach to this ticket the output of "upower --dump" from your system when it's in this state wrt the two batteries?

Status changed to 'Confirmed' because the bug affects multiple users.

[Tom Stephens (tomtheinfguy)]

I can confirm this is still the case in 15.10 when using multiple batteries. The system power indicator does not total up all remaining time from all batteries.

[Antti Haapala (ztane)]

Here as well. The battery indicator is completely erratic - it goes up and down, shows totals from one battery or another, and whatever). In addition, my laptop (Lenovo T450) has hotswappable batteries, and I got a new one with different rating. Indicator does not seem to notice that I have a larger capacity battery in (energy full is 70+Wh, energy now at 35 Wh, indicator says the battery is fully charged).

Also, I wish there was a way to always display the indicators for each battery separately.
