Other than being a customer of Apple, just like you, I don’t have a relationship with Apple. All contributors here are end-users of Apple devices. This platform is where users with technical problems can seek help from other experienced users.
As for the data that users with this reboot issue have been invited to provide, I am attempting to identify any pattern or correlation between devices that experience this problem. I am lucky in that I have access to multiple devices that are not affected by this issue - so more data to add to the mix.
Devices of similar model or specification are not necessarily manufactured in the same assembly plant. Internal components and sub assemblies come from a variety of source-manufacturers - and may have some influence on occurrence or susceptibility to this problem. Whilst end-users cannot readily identify these differences, a pattern may emerge that can be fed-back to Apple Support.
