You can tell it's getting close because the screen will dim.
The tech bubble has never understood that the rest of the planet doesn't have the same weather as San Francisco.
Two things: first, Apple is headquartered in Cupertino, which gets quite a bit warmer than San Francisco. Second, I've seen phones overheat and shut down in the summer in SF. This isn't a bubble thing; this is a company prioritizing miniaturization over proper functioning. Form over function.
People buy iPhones because they know apple knows cold devices are bad
the design process is different for hardware because you can't just fix everything with a patch after-the-fact. You have to actually anticipate problems and account for them in your design, especially when you are charging people money for the product and marketing it as a remote solution.

They're unfortunately constraints, but for 95% of people they're workable constraints. If there are difficult problems with bumping these limits (I have no clue), it could just become part of the market definition.
I live in Minnesota. Last week, the high temperature, in the shade, was about 40°C. A device in the sun would easily see its temperature exceed 50°C. In the winter, overnight lows can go to -40°C. An outdoor device with thermal limits of -30°C to +50°C is not fit for purpose in many parts of the Midwest.
I suspect overnight lows of -40 are ok, because it sounds like it's -30 after the self heating.
There are definitely reports of people having it work through 40 degree heat waves, but I suspect that's close to the limit. Keep in mind it is white, so the sun isn't as bad as it could be.
I don't have stats to back this up, but I think it's the case that most people live in reasonably temperate climates, 50 degrees is really frickin hot (dangerously so), -30 degrees is really frickin cold (dangerously so).
From what I'm reading, it looks like the dish is passively cooled, which I find surprising. I would have expected at least a small cooling fan or something to provide a bit of airflow for convective cooling.
Like most stats, it is made up.
