Refresh rate measures how many times your phone's display updates the image each second. A standard phone refreshes 60 times per second (60Hz), whilst modern phones often offer 90Hz, 120Hz, or even 144Hz. Each refresh cycle redraws the entire screen from top to bottom.
Why it matters: Higher refresh rates make scrolling, swiping, and gaming appear noticeably smoother. When you scroll a webpage at 120Hz instead of 60Hz, your eyes see twice as many frames per second, reducing the judder that can cause fatigue during extended use.
Common scenarios where you'll notice the difference:
- Scrolling through social media feeds or long articles
- Playing action games with fast-moving objects
- Dragging items across the home screen
- Watching video content with panning shots
Important gotchas: Higher refresh rates drain your battery faster because the display works harder. Many phones offer adaptive refresh rates that drop to 60Hz when you're reading static content, helping preserve battery life. Not all apps or content actually use the higher refresh rate - you only benefit when the content matches the screen's capability.
When comparing phones, check whether the refresh rate is constant or adaptive. Also verify if it applies to the entire display or only certain regions. Some budget phones advertise high refresh rates but don't maintain them during demanding tasks.
