  We utilize a holographic construction to compute the entanglement negativity
for bipartite mixed state configurations of a single subsystem in $CFT_d$s with
a conserved charge dual to bulk $AdS_{d+1}$ geometries. In this context, we
obtain the holographic entanglement negativity for single subsystems with long
rectangular strip geometries in $CFT_d$s with a conserved charge dual to bulk
non extremal and extremal Reissner-Nordstr\"{o}m (RN)-$AdS_{d+1}$ black holes
at the leading order in a perturbation theory. We demonstrate that the
holographic entanglement negativity computed involves the elimination of
thermal contributions at the leading order confirming earlier results in the
literature. This also conforms to quantum information theory expectations and
constitutes further consistency checks for the holographic construction.
