A Chinese leaker, Fixed Focus Digital, claims the standard iPhone 17 and iPhone 17 Air will have 120Hz displays, but not Apple's ProMotion technology with adaptive refresh rate. This means they'll lack features like always-on display and may have reduced battery life. However, other sources, including Ross Young of DSCC, predict ProMotion for all iPhone 17 models, suggesting a discrepancy in information. Apple's September launch will clarify the situation.
