Earlier quoted context omitted.
I always wonder what people who say things like this are doing with their phones. Two generations of phones ago, these performance parameters were fine. What software has come out on Android phones since then that's made that performance level unacceptable?
Pixel phones have always been behind in hardware power. They're not performing at budget level, but compared to most OnePlus devices they are way behind in performance. In the Android world performance means longevity. Any Pixel tensor chip or non-high-end Snapdragon or MediaTek chip has a "smoothness" lifespan of 2-3 years.
This is the assumption I'm challenging. What are people doing on their phones that makes a two year old phone feel two years old?
Maybe it's 3d gaming, I don't do any of that on my phone but for any productivity apps, I don't think I've noticed an effective difference in my phone for years.
