One UI 9 beta adds new low-refresh-rate modes to stretch Galaxy battery life
Samsung's One UI 9.0 beta adds three new display refresh-rate options—20Hz, 26.67Hz and 40Hz—on the Galaxy S24 Ultra, S25 and S25 Ultra to better balance smooth visuals with battery life on LTPO screens; the modes could reach other LTPO Galaxy phones, though it's unclear whether they shipped with the devices or arrived via the beta, and similar capabilities are already present on the Galaxy S26 lineup.
