Confirming, the fix is not complete. I wonder why it takes them so much time to
implement such a simple calculation (they have the amount of energy remaining
and the power consumption, dividing one by the other yields the remaining time).
Actually, I could fix it long ago if it was reproducible in my setup.
Could you provide more info, please, which meters are available and which
are not? Or even patch is more than welcome. Thank you.
Here is an example of what is shown in a tooltip:
Battery 0: 97% charged, 0:00 left
Energy full design: 56160 mWh
Energy full: 40930 mWh
Energy now: 39900 mWh
Power now: 12804 mW
Current voltage: 12.178 V
So, everything is correct except the "0:00 left" part. Also, if the remaining
percentage, after rounding, is equal to 100%, remaining time is not shown at all, even if
the battery is discharging (and the plugin is showing that it is discharging).
Here is the listing of /sys/class/power_supply/BAT0:

From strace, I see that the plugin tries to access some files that are missing
here.
Here is the contents of /sys/class/power_supply/BAT0/uevent:
