The superradiant stability is investigated for non-extremal Reissner–Nordström black holes. We use an algebraic method to demonstrate that all non-extremal Reissner–Nordström black holes are superradiantly stable against a charged massive scalar perturbation. This improves the results obtained before for non-extremal Reissner–Nordström black holes.
