I don't really know what you are trying to say, you lost me.
You wouldn't use a LM317 or another linear power regulator when power consumption was a problem.
Linear regulator regulate the output by dropping the excess voltage as pure heat power dissipation. They just waste energy.
You would sure use a switching based up-converter in this case, if you were to use anything, not a linear regulator that can only drop down voltage.
I am not very sure what are you trying to tell with the numbers.
What I am going at is that if you have 1W on the input, you will have 1W on the output (minus loss due to inefficiency)
At the output it will be near to 1W for switching, but way below for linear.
Anyway, and again, the point of the thing was that if you have "mAh" it is relevant to know to what "V" this mAh refers, in order to know the energy storage, and in the end how long the thing will last.
