Morphology
The phrase literally evokes conserving one's breath (the air used for speaking), so a learner who knows 'save' (spare/conserve) and 'breath' (air used for speaking) can infer it means not to bother speaking or wasting effort on someone who won't listen. The possessive 'one's' is just grammatical; the relation between conserving breath and not wasting words is a straightforward metaphor likely predictable to a B1 learner.
Etymology
Save one's breath comes from the simple image of someone holding back their breath instead of speaking when no one will listen. So, it means 'to stop trying to persuade or explain something to someone who will not listen or care'.
