The Belgian striker joined the Blues from French cub Marseille in a £33million in early July before linking up with the squad following a short holiday after Euro2016.
"Batshuayi's shape is improving and he's starting to understand our idea of football," said Conte.
"I have been happy with his commitment and his attitude. He can improve a lot in the same way as the other players."
Conte is still trying to find a way to play two strikers together in his setup, which has recently consisted of a 4-4-1-1 formation, as the Chelsea future of Atletico Madrid target Diego Costa remains clouded while reports regarding a big-money move for Everton's Romelu Lukaku continue to swirl.
