  We investigate the application of a holographic entanglement negativity
construction to bipartite states of single subsystems 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 geometry in $CFT_d$s dual to bulk extremal and nonextremal
Reissner-Nordstr{\"o}m (RN)-$AdS_{d+1}$ black holes. Our results demonstrate
that for this configuration the holographic entanglement negativity involves
subtraction of the thermal entropy from the entanglement entropy confirming
earlier results. This conforms to the characterization of entanglement
negativity as the upper bound on the distillable entanglement in quantum
information theory and constitutes an important consistency check for our
higher dimensional construction.
