Phones with a 120 Hz LTPO display

LTPO is the backplane technology that lets a panel drop its refresh rate very low when the content is still, saving battery, and raise it when you scroll. Whether the panel is OLED or AMOLED is a separate matter; LTPO sits on top of one of them. A value that does not say LTPO is not listed here; when the maker did not state it, it is not assumed.

Refresh rate is how many times per second the display redraws; a high value makes scrolling and games smoother and drains the battery faster. The peak the maker declares is not always active; most devices lower it with the content. The products listed here state this value in their official specifications.
