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).

I was thinking whether this problem could be alleviated by building in extra capacitors as a reserve for transient high current consumption.

At the time android phones were suffering the same problem. The nexus 6p would randomly crash at 30% charge.
