On one hand, you are saying that this is a theoretical problem.
$begingroup$ Current in Series stays the same or is added but in a parallel connection current is split using current division. So what''s happening is in series all the current is being pulled at once whereas in parallel the current is being "split" while being pulled hence it will also make the battery last longer. $endgroup$
