When were you planning to upgrade your three year old phone? I upgraded for same reason as you (6 plus), but when I found out I could have paid $85 for a new battery to restore much of my performance my reaction was, meh. I would have still upgraded anyways.

Even if there wasn't CPU throttling to keep old phones usable, software marches on adding features and benefits.

iPhone 3: 256 Mb ram

iPhone 4s: 512 Mb ram, 490 multicore Geekbench

iPhone 5: 1 Gb ram, 1,203 multicore Geekbench

iPhone 6s: 2 Gb ram, 3,888 multicore Geekbench

iPhone 7 Plus: 3 Gb ram, 5,763 multicore Geekbench

iPhone X: 3 Gb ram, 10,108 multicore Geekbench

I have always been amazed at Apple's ability to shoehorn iOS versions and new features into such limited memory capacities (compared to Android for example). But there is always a limit to what can be done.

My daughter's iPhone 5 shipped with iOS 6, and is currently running iOS 9. Is it slower? Yes. Does it have more features than when released, heck yea.
