Longer flights ≠ last longer.
The reason that a lower charge rate results in a longer flight is that you achieve a more complete charge. More complete charge has been empirically demonstrated to result in fewer usable cycles than charging to a lower termination voltage. As such, lower charge rate can result in lower battery life (# of useful cycles).
