battery.el broken?

battery.el broken?

[T.V Raman]

Used to display battery percentage and time left; now says

Power on-line, battery discharging (93% load, remaining time 0:00)

The default output format of 'M-x battery' has barely changed across
several Emacs versions (though different battery-status-function
backends call things by different names, e.g. AC vs on-line).

So I'm guessing the "broken" part is the contradiction between on-line
and discharging, and the zero remaining time to full/empty.

If so, please say which Emacs version you're running and what your value
of battery-status-function is.

If you're on Emacs 28 with battery-upower, you can see all the
information returned by the system UPower daemon by evaluating:

  (mapcar #'battery--upower-device-properties
          (battery--upower-devices))

The returned alists will include relevant keys such as Online, State,
TimeToEmpty, and TimeToFull, all of which are documented at
https://upower.freedesktop.org/docs/Device.html.

If the returned alists are internally inconsistent, then it's not Emacs'
fault.

If they look fine but the result of the battery-upower function
disagrees with them, then there's an Emacs bug in the translation,
indeed.

Feel free to post the relevant data here for help with deciphering it.
(Excluding the Vendor, Model, and Serial properties I guess, in case
they're considered sensitive?  I have no idea.)

HTH,

You might also want to try using another of those
battery-status-functions to see if that helps.

Typing this with the machine fully charged and not plugged into the AC

Hm, did you always have those ucsi-source-psy entries?  Searching for
them online led me to the following relatively recent discussions on
USB-C power sources, UPower, and Linux:

https://forum.manjaro.org/t/upowerd-not-recognising-usb-c-path-charger-is-usb-c
https://gitlab.freedesktop.org/upower/upower/-/issues/126
https://bugs.launchpad.net/ubuntu/+source/upower/+bug/1891799

In particular I notice that the first of the two ucsi-source-psy entries
says ("Online" . t), which seems contradictory and is probably what
throws battery-upower off.

yes, looks like some upower dbus  bug; separatley, for the longest
time the dbus api has been reporting AC power connect/disconnect
*much* after the event.
It's pretty broken, and not Emacs' fault.

the upower commandline utility gives the right value by the way

And on the same machine a few mins later:

(setq battery-status-function #'battery-linux-sysfs)
M-x battery displays the time left:
Power BAT, battery Discharging (98.7% load, remaining time 10:48)
(battery-linux-sysfs)
