Hawking radiation enhances quantum battery capacity in black hole spacetimes, counter to typical noise effects, with degradation patterns depending on noise type.
A dissipative two-mode ultrastrongly coupled bosonic system yields enhanced charging energy and ergotropy in transient and steady states through combined interactions, with the vector potential term preventing phase transitions in the deep-strong regime.
