<<Yep, the 48 V phantom power scheme is actually a huge waste of
energy. Assuming that the 48 V phantom power voltage provided by the
recorder is regulated down to 5 V inside the microphone,>>

Can we actually make that assumption overall?

<< then only about 10 % of the provided energy is actually used to
power the microphone. The other 90% is just converted into heat...>>

Voltage alone is not an indicator of the amount of energy available
for consumption in a circuit. Voltage has an inverse relationship with
current. Thus, if current needs are kept low, a circuit can run on a
high voltage without drawing any more available power from the supply
source. Generally microphones which run on both battery as well as
phantom power have considerably better noise & headroom capabilities
with the greater current supply available with a phantom supply.
