Gotta be waaaaay less than 80% for that to happen, surely

It happened to me too, even if my battery health is 92%

Maybe a bug?

Nah. Battery health is a measure of overall capacity relative to new. The battery could be 92% capable of holding a charge, but chemically degraded in a way that it cannot output the same peak voltage or amperage.

The phone momentarily ramps up and demands full power, the battery can’t deliver, the system crashes and reboots. After reboot, performance management is applied to prevent the CPU from exceeding the battery’s current maximum output capability.

Not true, had it happen on my iPhone X with 85% battery health, got it replaced and issue went away.

I had an X but upgraded to the 13 pro after I saw the battery improvements, apple really did skimp on them for so long
