He understands it just fine. He doesn't care how long the total life span is. It's perfectly capable of it (access to the option can be paid for so it's not equivalent to a hack) and he wants to go further on a single charge, so this is a perfectly reasonable tradeoff to make. Just let the user make that choice without an absurd subscription.
