That will depend a lot on what gears you are in. At higher gears friction of servo by itself might be enough.
At lower gears drain is significantly higher, and may, in fact, burn the servo after a long climb in lowerst gear (despite it not actually helping you to climb that hill, lol).
I recommend you to use a wattmeter (there are ones for arduino) and see for yourself.
It depends on strength of derailer tension spring though... an other idea is "balanced" shifting, with a spring that counteract tension of the return spring.
Also, the is "servo jitter" phenomenon that cause additional drain on the battery when servo is heavily loaded. Have you tried tackling it?
