It's not a fact because it was never shown, you're just assuming he was fighting throughout the time he was off screen when there's no proof of that. He said he was worried about his chakra volume when he was about to use a very chakra taxing technique that consisted of a shadow clone and his original body both using raikiri's.

The lightning cable jutsu was going make a significant dent in his reserves so of course, he would be worried. His statement does not confirm that he was fighting for a whole day, that's a wild conclusion to draw from such a vague statement.
