Problem: For example KDE DOES try to do this, but the "time-to-empty" information is missing for "fully charged" batteries! Hence, the frontend is not able to calculate a total battery lifetime...
See:
mo-thinkpad01:~ # upower -i /org/freedesktop/UPower/devices/battery_BAT0
...
battery
<NO "time to empty" available as battery is not discharged>
mo-thinkpad01:~ # upower -i /org/freedesktop/UPower/devices/battery_BAT1
...
battery
time to empty: 10.2 hours
Is this a known limitation?Yes. Or you can use UPower 0.99.x which fixes that through the concept of a "display battery", which will put together all the information from all the batteries and not require every front-end to do that.I would like upower to provide an additional "overall-time-to-empty" value using ALL batteries / energy sources installed.That's already done, you're just using an old version of UPower :) Cheers
Ok, great! I will look at upower 0.99 and try to create a patch for KDE. -- Dipl.-Ing. Joschi Brauchle, M.S.
