The capacity of entanglement is one of quantum information measures that plays a similar role as heat capacity in thermodynamics when the replica parameter is regarded as the inverse temperature. We examine whether the capacity of entanglement can probe gravitational phase transitions associated with a black hole evaporation process. In toy models describing Hawking radiation, we find the capacity typically shows a peak or discontinuity around the Page time when the dominant gravitational saddle switches between replica wormholes of different topologies. Similarly the capacity is shown to be sensitive to the dominant gravitational saddle in the JT gravity, being an invaluable diagnostic for a black hole evaporation process.
