All things with a LiIon battery do battery management to avoid extreme draining or charging. I've never seen a phone that offered a choice of "more battery cycles vs slightly longer run-time".

For cars, it's not an unusual feature to be able to choose. The Leaf has that feature, and since it cycles its small batter frequently, it's an important consideration for owners. See:
