Call me a crotchety old man, but we’re hitting the point where SoC no longer feels like the limiting factor of phone performance.
Unless there’s somehow a dramatic improvement in energy efficiency, new SoCs don’t really see a benefit without some other significant advancement. E.g., significantly higher resolution displays, bigger and better image sensors (with the storage to back them up), etc.
Not saying there’s not more that can be done with faster phones, but more that the average user browsing the web, scrolling social media, and taking selfies will never notice a 20% increase in performance unless it’s paired with something else.
