When choosing between a 90Hz and a 120Hz display, I found that the higher refresh rate offers noticeably smoother scrolling and animations, especially when browsing or gaming. The difference is subtle but evident once you get used to the fluidity of 120Hz screens. However, the 90Hz display still provides a great improvement over the older 60Hz standard while consuming less battery. In my daily use with a 120Hz screen, I also noticed enhanced touch responsiveness, which makes typing and navigation feel more precise. Adjusting the touch sensitivity setting further improved the interaction, something available in most modern smartphones under display controls. However, not all apps support higher refresh rates seamlessly, and sometimes the battery drain on a 120Hz screen can be more noticeable compared to 90Hz. It's worth experimenting with these settings to find a balance between smoothness and battery efficiency that suits your needs best.
