many times: hiking, on a boat, riding my motorcycle, on vacation in general. during these times i don't want to be unnecessarily tied to a portable charger. what's the point of having a portable phone at that point. simply changing out a battery is far more convenient. so it's not theoretical at all. the person i replied to literally listed a reason why it's nice to be able to swap out a battery: their battery no longer works correctly.
