I agree with you, phone companies have developed a planned obsolesce model that is very frustrating. I actually just went through the same process in the opposite direction - I switched from having iPhones to Android. I've heard tales of iPhones staying capable and functional for many years but my experience was that after a year or two there'd be an update that drastically reduced the performance (or rendered it basically unusable which happened 3 times). I suppose the grass is greener on the other side but I'm pleased so far with my switch. Good luck.
