I wonder how charge evaporates from a charged black hole? And does it do so at a rate that is different from the mass? i.e. does most of the mass evaporate away, and then the charge?
So it would seem that a charged black hole would evaporate by Hawking radiation until it reached the point where any further mass loss would put it over the charge limit. Physicists don’t think it is then simply going to stop radiating, and so what happens then is I believe still quite open.
There was an article in Quanta a few months ago on this: https://www.quantamagazine.org/black-hole-paradoxes-reveal-a...
