Long story short, rumors suggest that both the iPhone 15 and iPhone 15 Plus will be stuck with a static 60Hz refresh rate. The iPhone 15 Pro and iPhone 15 Pro Max are expected to inherit the adaptive 1-120Hz refresh rate technology (dubbed ProMotion) of their respective predecessors, but many expectant iPhone fans were hoping that Apple might make this Pro-level feature available to every model in the iPhone 15 line.
Fuck click bait.
