Is there some documentation that explains what different power supply
statuses mean? Because without that, we can have long and useless
discussions.

Well, I couldn't really find much except the following from
Documentation/
(which is not that helpful, and the BATTERY_STATUS_* don't seem to exist
anymore):

" STATUS - this attribute represents operating status (charging, full,
discharging (i.e. powering a load), etc.). This corresponds to
BATTERY_STATUS_* values, as defined in battery.h. "

Generally speaking, I think the question to be asked is what information
users
will be interested in in each scenario we have to consider.

Hmm. We really should add some documentation :-(.

Maybe we should start a new thread about this to give it more visibility.
That way, PM maintainers could weigh-in and share thoughts.

I definitely agree there is a need to clarify what we want to report to
userspace given the various scenarios we've been discussing.

+1 for extension and update of documentation. If its known, that
the battery is trickle charged, it should report FULL. No need
to annoy people by constantly updating the status. Think of it
being mapped directly to a status LED. Of course the CURRENT/ENERGY
properties should still be updated, so that anyone interested in
the details can see them.

Agreed. Do ou think there is a need to start a specific discussion about
various scenarios and how to handle them or do shall we just use common sense
here?
