Refresh rate kya hai, aur kab zaroori?
120Hz
Refresh rate batata hai ki screen ek second me kitni baar nayi image dikhati hai. 60Hz me 60 baar, 120Hz me 120 baar. Zyada refresh rate se scrolling aur animations smooth lagte hain, aur supported games me fark saaf dikhta hai. Lekin isse battery thodi zyada lag sakti hai, isliye achhe phones adaptive refresh rate use karte hain jo zaroorat ke hisaab se badalta hai.
