One UI 9 Introduces a Hidden Feature to Boost Battery Life on Galaxy Devices

Samsung has recently rolled out One UI 9 beta updates to a variety of eligible Galaxy smartphones, giving users an early look at refreshed visual elements and system upgrades. Beyond the obvious aesthetic changes, the software introduces a subtle yet highly effective power-saving feature designed to maximize battery endurance on premium Galaxy phones and tablets equipped with advanced display technology.

How New Refresh Rate Modes Optimize Power Consumption

Acutely observant Galaxy S25 and Galaxy S24 owners discovered that the One UI 9.0 release quietly adds three brand-new display refresh rate configurations. Specifically, these flagship lineups have gained native compatibility for 20Hz, 26.67Hz, and 40Hz refresh rates.

By providing a granular selection of refresh rates, the operating system can choose the most precise panel configuration to balance visual fluidity with overall battery retention. For instance, when displaying static content or minimal on-screen movement, the phone can throttle down to a 20Hz refresh rate rather than remaining locked at 24Hz, shaving off minor amounts of power use to extend daily battery runtimes.

Supported Devices and Future Integration

These enhanced energy-saving steps have been verified on the Galaxy S24 Ultra, the standard Galaxy S25, and the Galaxy S25 Ultra. Because models like the Galaxy S24+, Galaxy S25+, and Galaxy S25 Edge utilize versatile LTPO display panels, they are fully expected to benefit from these exact additions.

While these low-rate modes come pre-installed on the newer Galaxy S26 series running One UI 9.0, deploying them to older generation flagships via software updates proves Samsung's ongoing dedication to refining power metrics across existing hardware.

Which Galaxy models support the new 20Hz and 40Hz refresh rates?

The newly introduced refresh rate options have been confirmed on devices like the Galaxy S24 Ultra, Galaxy S25, and Galaxy S25 Ultra, with broader support expected across other LTPO-screen models in the ecosystem.

Why does lowering the refresh rate help save battery?

Display panels consume less energy when they refresh fewer times per second. Dropping down to slower rates like 20Hz during static screen usage significantly reduces active power draw compared to higher rates.

Are these settings user-configurable?

No, the system handles these low-level refresh rates automatically depending on the app or content on your screen to ensure the optimal balance between performance and battery life.

🔎 Ultimately, while dropping refresh rates to these granular levels may seem minor on paper, these progressive power optimizations accumulate throughout the day to deliver a tangible improvement in daily battery longevity for Samsung's high-end smartphone users.
