Unruh and Schwinger effects are the two well-known phenomena in the relativistic quantum field. Here, we study their joint action on quantum correlations (entanglement negativity and quantum mutual information). We consider an entangled two-mode fermion fields, in which one mode undergoes Unruh effect with constant acceleration and the other undergoes Schwinger effect of constant electric field. It is found that both relativistic effects degrade the quantum correlations of the initial state, which are then redistributed among the particles and antiparticles produced by the two effects. The different behaviors exhibited by the two relativistic effects and the conservation of quantum correlation in the process are investigated.
