Modeling the collapse of an extreme Reissner-Nordstr¨om (ERN) black hole by solving the corre sponding moving mirror model for the trajectory that asymptotically approaches uniform accelera tion, we obtain the non-zero beta coefficients for all times. Finite energy is emitted, the radiation
spectra is non-thermal (non-steady / not Planck), soft particles characterize the evaporation, and
particle production at ultra-late times is damped. Entanglement entropy diverges with no Page
curve turn-over, demonstrating non-thermal information loss. The radiation obeys time-reversal
symmetry
