I wonder if this turned out to bake an attached device, if Motorola would have to accept their design caused third party damage? I can't see how you'd get a case up but a class action, if enough people got devices fried, seems possible. Spec is a spec. You match the spec.

(does not feel likely)

My G85 is newer and has the same issue at 5.5V, thermal camera doesn't start (probably OVP) and one sdcard reader works but it gets very hot.

I found a workaround by unplugging and replugging as quick as possible, it goes back to ~5.0V.
