So I guess we can't tell whether charging is happening, only that he
charger is plugged in?

So we have no free characters that we can define then? In that case we
need a short text to describe the item. "Batt: 10h15" gives 11 characters,
which is as wide as we can get on player without inducing scrolling, so
maybe we go with that. For consistency, perhaps we should use the same
text for recorder/FM?

But the other models do, and I would rather avoid having differences
between the models unless there is a good reason. This is not a good
reason :-)
