We analyze universal conductance fluctuations (UCFs) in graphene in the framework of diagrammatic perturbation theory in the metallic regime. It is shown that strong intervalley scattering lifts the valley degeneracy of electronic states, whereas at weak intervalley scattering two valleys independently contribute such that the variance of UCF would be expected to show sample- and geometry-dependent behaviors.
