This is mainly achieved through an OLED display on the iPhone X that has a 1000000: 1 contrast ratio, compared to the iPhone 8 Plus of only 1300: 1 and iPhone8 of only 1400: 1.

But the conference made it clear that iPhone X's battery life can be longer than the iPhone7 2 hours.

Although Apple did not elaborate on how this additional 2-hour battery life was achieved, a comparison of battery life provided by Apple showed that iPhone X and iPhone 8 Plus last about 21 hours of talk time, iPhone8 test results for 14 hours.
