What is Refresh Rate?
How many times per second a display updates - measured in Hz.
Refresh rate measures how many times per second a display updates its image, expressed in Hertz (Hz). Higher refresh rates result in smoother motion and more responsive touch input.
| Common Refresh Rates: | |
|---|---|
| ------ | ------------ |
| 60Hz | Standard, slightly choppy |
| 90Hz | Noticeably smoother |
| 120Hz | Very smooth, gaming-quality |
| 144Hz | Ultra-smooth (gaming phones) |
| 165Hz | Maximum (gaming phones) |
Benefits of Higher Refresh Rates
- Smoother scrolling and animations
- More responsive touch input
- Better gaming experience
- Reduced motion blur
- More natural-feeling UI
Battery Impact
- 120Hz uses ~10-15% more than 60Hz
- LTPO displays drop to 1Hz to save battery
- Adaptive refresh rate is the best balance
Higher refresh rates use more power:
Variable Refresh Rate
Modern phones adjust refresh rate dynamically:
LTPO technology enables this variable refresh rate on phones like iPhone Pro, Samsung S-series, and OnePlus flagships.
