쿨링 : 노트8과 비교시 큰 차이점을 발견 못함

There was no noticeable temperature difference between the Note 9 and Note 8, which has a smaller thermal spreader and lacks water/carbon fiber cooling. 

배터리 : 노트8에 비해 15분 정도만 더 감

However, the Note 9 lasted just 15 minutes longer than the Note 8, which has a much smaller 3,300 mAh battery. The Pixel 2 XL lasted 12:09 on our test, more than a half-hour longer than the Note 9's best time (and Google’s flagship has a better camera, to boot). The Galaxy S9+ hits 10:59
