>> The reports all mention that the crack became visible suddenly and for no apparent reason, after the headsets had been connected to the external battery pack and stored overnight (some in Apple's Travel Case) with the soft front cover attached.

It is glass. The device was being charged, which means some heat gradient between the charging battery and the outside world. That thin 3d-shaped glass cracks under thermal stress should be no great surprise.

There's no battery behind that glass, so it's the processors or another component generating heat while stored.

Maybe no surprise to Apple, but it is certainly a surprise to the purchases who shelled out $3,500.

IIUC there's no lithium battery inside the Apple Vision Pro at all. The power for it is supplied by an external batter connected via USB cable.

The battery is external, but mobile. The users may well have stored it inside the thing. Plus, it is understood that this device continues to draw power while not in use, which also suggests a possible thermal gradiant.

It would be a huge surprise for Apple if a lithium battery inside the visor caused the cracks, as they did not design the head unit to include any internal battery.
