Not sure how my 4 year old Galaxy S6 still chugs along as fast as the day I got it. I'll purchase a new battery before getting a new phone (still on the original, which still makes it through the day on a charge). I'm pretty sure I could easily get another 4 years out of this. CPU and RAM are not an issue. I don't need or want AR or gimmicks that don't actually add value or productivity. Just a tool. My email and texts all still work fine as well as all of the business apps I need, websites I visit, etc. You don't need to upgrade every 2 years, or probably even every 4 years. People are more than welcome to spend the money if they wish, though. They've been trained well into thinking they do.
