Not a ding or scratch story, but rather one involving direct sunlight and the resulting high temperature.
I used my iPad to run a navigation app while cruising in our trawler.
Bummer of bummers, about four years ago I left the iPad exposed to direct Florida sunlight through the glass of our pilothouse and the iPad shut itself down. I presume there's a self-preservation mechanism that triggers once the device hits a certain critical temperature.
Fortunately, being the tough beast that Apple seems to create, I was able to turn the iPad back on after about 30 minutes of cooling in the shade and it has worked ever since, albeit with a battery endurance of only an hour or two.
A friend recommended that I replace the battery but my nervousness about doing that outweighs my desire or need to run the thing unplugged.
Lesson learned...and never repeated.
