With most 2026 flagships pushing 90 to 144 Hz, Samsung’s One UI still bumps many interfaces to 120 Hz even when video playback sits at 60 Hz, like in YouTube. On May 5, 2026, Les Numériques’ Antoine Roche highlighted Samsung’s free Display Assistant, which lets Galaxy apps, including on the S26 Ultra, be locked to 60 Hz to modestly trim battery use.
Smooth screens are great until your battery pays the price. On Samsung phones like the Galaxy S26 Ultra, One UI’s adaptive mode can still push apps such as YouTube to 120 Hz while you scroll, even though playback itself sits at 60 Hz. Samsung’s free Display Assistant lets you lock chosen apps to 60 Hz, trimming unnecessary refresh spikes. The payoff isn’t dramatic, but it’s an easy, targeted fix that adds up over a day of mixed use.
You know that thrill when your phone feels buttery smooth, then the slow dread as the battery drops faster than you’d like? High refresh rate screens are a gift and a tax. Devices like the Samsung Galaxy S26 Ultra can push silky animations, but they also pull extra power. There is a simple, targeted fix hiding in plain sight.
Modern screens can jump between 90, 120 Hz, and even 144 Hz, which is great for gaming and fast scrolling. That speed asks more of your battery with every frame. One UI’s adaptive mode helps, but it is not perfect for every app. This is the case with YouTube: videos sit at 60 Hz, yet the app UI often spikes to 120 Hz and wastes energy while you browse.
If that mismatch sounds familiar, Samsung’s Display Assistant can step in. The free utility in the Galaxy Store adds per-app control, so you can lock less demanding apps to 60 Hz and stop those needless jumps. You keep smoothness where it matters, and trim the excess where it does not. The feel stays consistent, the battery drain eases.
Here is how to rein in refresh rates on a per-app basis without changing your whole phone’s behavior:
Try capping video and news apps first. Keep games or heavy social feeds on adaptive if you value that snappy feel.
You will not double your battery overnight, but you can slow the slide during long days. According to this approach, trimming those background spikes adds up across hours of scrolling and streaming. In addition to refresh controls, Display Assistant offers other screen tweaks you can explore later. Small, specific changes often deliver the most reliable wins.
