> I am still using a IPhone released in 2020 with absolutely no appreciable slow down or losses in perceived performance.

My Pixel 4a here is also going strong, only the battery is slowly getting worse. I mean, it's 2024, do phones really still get slow? The 4a is now past android updates, but that was promised after 3 years. But at 350 bucks, it was like 40% less than the cheapest iPhone mini at that time.
