Why are people bringing up Naruto having his stamina and chakra replenished from Kurama throughout the war? They do know that doesn't fully heal Naruto right? There's a reason Tsunade, the best medical ninja, would have those she healed rest for days to weeks for their body to fully heal. This happened with Kakashi, Sasuke, Lee, Neji, Naruto, Choji, Kiba and Akamaru in part 1 and Kakashi and Naruto in Shippuden. So Naruto's body doesn't get healed excepted when Sakura healed him twice and even then it's not fully healed. Kurama healing heals him faster but when he rest not in constant fights that gives him more injures.
This is why Naruto's own chakra is really low, it had no time to replenish and is why Kurama said the war left Naruto's chakra low. Kurama gives Naruto his chakra which Naruto uses, it doesn't replenish Naruto'd own chakra.
