Samsung has added new display options that could reduce power consumption, alongside visual changes, in the One UI 9 beta updates it has rolled out to supported Galaxy models in recent weeks. According to examinations of some models in the Galaxy S24 and Galaxy S25 series, One UI 9.0 supports refresh rates of 20 Hz, 26.67 Hz, and 40 Hz. The new intermediate levels allow high-end phones with LTPO displays to adjust their refresh rate more precisely and automatically according to the content being displayed. The system can switch to higher rates for scrolling, animations, and games, and to lower rates for content with limited motion. For example, using 20 Hz instead of 24 Hz could provide small energy savings, while 26.67 Hz and 40 Hz could prevent unnecessarily high rates while maintaining smoothness. However, actual battery savings depend on brightness, apps, content, and usage time; it is still too early to claim a significant increase in battery life.
Why it matters
The main significance of the change is that the display can respond more precisely to the type of content instead of operating at the same refresh rate in every situation; this offers a more precise approach to power management, especially for the Galaxy S24 and S25 models with LTPO displays. For users, the potential benefit may come from preventing the display from working harder than necessary with images containing limited motion, without completely sacrificing smoothness. However, the extent to which this effect will be reflected in daily use may vary from person to person due to variables such as display brightness and the apps being used. How these options in the beta version will be implemented in the stable release, and whether they will create a measurable difference in total battery life, remains unclear.
