What exactly does that process look like? I'm imagining a bunch of QA techs in a warehouse hoping for failure.

Maybe lots of extreme cases, like wrapping up the phone to try to overheat it, lots of testing of wireless charging (which seems to be a link between known cases), tests with various cables/chargers, maybe trying to get the phone wet...

I would imagine also writing code to execute on the phone designed to max out the CPU/GPU for an extended period of time?
