The animation that constantly changes the "charge level" is currently the way
to show that you recharge (plus the LED light if that setting is enabled), so
how should this be displayed?

The widget in the statusbar could be changed, such that the charge level only
starts to rise starting from the current charge level (in the same way you see
it in many other phones. Also, some more detailed info (% charged, ETA to full
charge) could be added in the menu that appears when you click the statusbar
widget. There now is a battery icon, but it does not add much information to
what is already in the statusbar.

How should it be displayed that the battery is only 95% full instead of 100%?

OK, fair point. How about overlaying an icon over the green bar (e.g. of an
electric plug) while charging and indicating the charge level by the height of
the green bar underneath (without it continuously rising)?

Anyway, I think more information should be available somewhere, such as in the
menu that appears when you click the status area.

Is the status-area-applet-battery source publicly available? If not, where
should a request for opening it be made?

It isn't, but see <https://garage.maemo.org/projects/advanced-power/> and
<http://talk.maemo.org/showthread.php?t=14115> for alternatives.

> If not, where should a request for opening it be made?

I believe <http://wiki.maemo.org/Open_development/Why_the_closed_packages>
would be the canonical place for such requests.

BTW, FIXED isn't quite the right resolution since no one actually fixed
anything :-)  I think this is most likely a WONTFIX (but feel free to reopen if
you disagree), since BME doesn't provide charge percentage while a power source
is plugged in, just the "charging" state.

(In reply to comment #3)

The percentage (along with other info, see below) could be displayed in the
status bar expanded view.

I was wrong, that information is available on the N900:

Round the starting level down, i.e. the battery icon should animate between the
last two icons (representing 87.5% charge and 100% charge; assuming there are 8
separate icons for different charge levels).

The charge level lshal reports doesn't change while charging. So it may not be
technically possible after all.

You are right, and the dbus bme interface doesn't provide any more info than
previous versions either :-(

Not closing again as there may be something else I'm overlooking.

If the batteries of the n900 are dumb and the whole logic is software (bme),
then you (a nokia employee) could modify bme to export this information through
dbus.

The Maemo 5 User Interface and Maemo 5 platform components (e.g. libraries)
used for the N900 are considered stable by Nokia and it seems that there are no
plans for official updates currently, hence nobody plans to work on this
enhancement/wishlist request. 
(And in case you feel like discussing this situation: Nokia Customer Care or
http://talk.maemo.org would be the place to do so as you will not reach Nokia
officials in this community bugtracker - though all of this is really no news.)

Reflecting this status by setting RESOLVED WONTFIX for this
enhancement/wishlist request (see
https://bugs.maemo.org/page.cgi?id=fields.html#status for status explanations).

There is a small chance for issues in those Maemo components that are open
source: Contributed patches could be included and made available in the Maemo 5
Community CSSU updates. 
The Maemo CSSU project is run by a small team of volunteers; see
http://wiki.maemo.org/CSSU for more information.
So in case that you can provide a patch that fixes the reported problem, please
feel encouraged to file a request under
https://bugs.maemo.org/enter_bug.cgi?product=Maemo%205%20Community%20SSU .
Please note: The Maemo CSSU project is not related in any way to Nokia.
