아난드텍 분석결과에 따르면 

Apple’s 120Hz refresh rate seems to work very similarly to Samsung’s LFD VRR, in that the display can vary itself between a few discrete refresh rates, ranging from 120Hz through 80, 60Hz, and a few other low frequency refresh rates down to 10Hz. The frequencies presented by Apple are similar to what Samsung exposes in its drivers, which wouldn’t be surprising if they’re both based on the same panel technology.

In the 120Hz result set, for which the new iPhone 13 Pro models are now the first Apple devices amongst the competition, the new phones directly introduce themselves as top performers.

The iPhone 13 Pro and 13 Pro Max lose respectively 14.5% and 13.5% over their 60Hz results which is generally in line with the 12.2% degradation the S21 Ultra sees – you can argue if Apple’s 60Hz is more efficient than Samsung’s or if Samsung’s 120Hz is more efficient than Apple’s, the difference remains small.

Given the much smaller battery of the 13 Pro Max, seemingly similar display technology and efficiency to the S21 Ultra, Apple’s battery life advantage remains in my opinion squarely on the massive efficiency advantages of Apple’s silicon, with the new A15 further increasing this discrepancy compared to the competition.

보시다시피 60hz 120hz간의 배터리타임 차이는 s21울트라는 12.2%차이,  13프로와 13프맥은 각각 14.5% 13.5%차이입니다. 오히려 s21울트라가 차이가 적죠.  아난드텍 해석처럼 애플의 60hz가 효율이 더 좋다고할 수도 반대로 120hz모드에서 삼성의 효율이 더 좋다고 할 수도 있죠.  드라이버단에서 보여지는 주사율 작동방식 차이도 거의 없구요. 그냥 아난드텍 말처럼 배터리타임 차이는 애플실리콘과 퀄컴(또는 엑시노스)의 차이죠
