The overheat shut down of iPads has been known and reported since the release of these products years ago. Heat accelerates the deterioration of all electronic components under all circumstances, although some components are a bit more tolerant than others. Ambient temperature is irrelevant from an engineering perspective. Apple's Guidelines are written by lawyers for consumers who might sue for melting their iPhone by leaving it on an automobile glare shield on a sunny day in Las Vegas. The actual technical detail is that these devices have an internal temperature sensor which activates a shut down process at a CPU temperature of 145F if memory serves (and these days it may not). If you arrange for convective or forced air cooling of the device in your cockpit, the ambient temperature is much less important. The Garmin products you mentioned were designed for use in hot cockpits and also for use in bright sunlight. The Apple products were designed for light weight, long battery life, and convenient form factor for their intended purpose. Life is a tradeoff and many people use iPads, etc. in flight because the software is arguably much better (easier to use, more features, etc) and the software vendors like Foreflight charge much less for database updates than the bloodsucking Garmin or Jeppesen. Life is a tradeoff. Also, allow me to correct a misperception. Running Foreflight (for example) does not make an iPad (or any computer running an application) work "harder". The machine is running the same CPU clock if running your app or sitting in an idle loop. In the case of iPads and iPhones, the rapid updating of GPS position does slightly increase battery draw, but this can be more than compensated for by shutting off the baseband functions (i.e., the cell phone functions in flight) which draw far more power than the GPS. The most power consumption in one of these products is usually the backlight behind the LCD screen. In a bright cockpit like a Europa, you would almost certainly set the screen brightness to maximum, whereas in a Cessna, the screen would be readable with far less brightness.
