The forthcoming iPhone 17 and iPhone 17 Air are anticipated to come equipped with 120Hz display technology. However, recent insights suggest these screens might exhibit a notable limitation.
Historically, ProMotion technology has been a feature exclusive to the Pro models. In September of the previous year, display expert Ross Young indicated that this feature would be extended across the entire iPhone 17 series. Subsequent sources have corroborated Young’s prediction. Yet, fresh reports from China indicate the iPhone 17 and 17 Air might lack an adaptive refresh rate akin to the ProMotion displays.
This implies that the iPhone 17 and 17 Air could present a fixed 120 Hz refresh rate rather than an adaptive one. ProMotion displays harness LTPO technology to enhance battery efficiency by dynamically lowering the refresh rate to as low as 1 Hz when high refresh rates aren’t necessary.
The potential absence of adaptive refresh rates could detrimentally affect the battery performance of the iPhone 17 and 17 Air. LTPO panels are a staple in premium smartphones due to their ability to modify refresh rates dynamically without requiring extra hardware, albeit at a higher cost compared to LTPS technology displays.
Apple’s choice to potentially bypass LTPO for these models might be financially motivated. Nevertheless, it’s important to emphasize that this information remains speculative at this time.
