You can use AsyncStorage.setItem() to update posts with the postItems.

removePost = async (post_id) => {
try {
  const posts = await AsyncStorage.getItem('posts');
  let postsFav = JSON.parse(posts);
  const postsItems = postsFav.filter(function(e){ return e.post_id !== post_id });

  // updating 'posts' with the updated 'postsItems'
  await AsyncStorage.setItem('posts', JSON.stringify(postsItems));

} catch(error) {
  console.log('error: ', error);
}};
