That’s not an option. It’s not that the battery was flat. It’s that when the CPU hit peak power consumption the voltage of the battery would drop low enough to cause the CPU to fail. The only option is to limit power draw or to crash.
No, actually, it IS that the battery was flat, and it IS an option. Apple chose to use a battery which was not durable enough for the requirements imposed upon it by their design. I'm not sure why you think that they couldn't have avoided it like LITERALLY EVERY OTHER PHONE MANUFACTURER (including themselves at one time).
