actually, doned/gifted chakra can remain in people, if they used it for long enough. nagato had madara's rinne for so long, it was reawakened in his edo form. as well as in obito, after he lost the juubi, and the other jinchuriki, who had bodies adapted to their bijuus, and that made them able to use them even after death. how did Naruto manage to keep the kurama cloaks on the shinobi alliance even though he was fighting someone else? they just got his chakra, and kept some of it, as choji, shikamaru, sakura, ino, and some others stated. they kept it for enough time so that Naruto could refill them to their full powers faster. as well as when madara stole hashi's chakra (both normal and senjutsu) to use for himself indefinitely.
