We derive approximating analytical solutions to the system of Klein-Gordon-Maxwell-Einstein equations, describing a minimally coupled charged boson to a spherically symmetric spacetime. Within a first-order perturbative approach, we generalize some previous results and write down the effective potential and the current, for the non-vanishing radial-momentum case. These can be actually employed in computing quantum transitions, such as the ones related to gravitoelectric particle creation. It can be noticed that the non-vanishing radial wave number affects both the effective potential, by a gravity-based dipole contribution, and the current. These lead to serious consequences regarding the actual dispersion, the continuity equation and the growth, and respectively decay, of the quantum mode-excitations.
