Yes, that's about correct.

This can have a couple of reasons. It will for
example be that way when the Newton was switched
on, displayed the warning, then went to sleep and
was charged before you turn it on the next time.
It can also happen if you draw much current from a
weak battery (maybe using an ethernet or a WLAN card
or one of Adriano's NewtLights). The displayed capacity
will increase after current consumption has returned to
normal conditions.

This is wrong. The capacity is derived from
the battery's voltage. The temperature is only
evaluated while charging to prevent overcharge.
