I am in a bit of a dilemma: I currently have an iPhone XR and am looking to upgrade this year. I am not sure whether to get the iPhone 17 or the iPhone 17 Pro Max. This time, I want to keep the phone for about three years. I like the 12 GB RAM, vapor cooling, and improved cameras on the Pro Max. If I were to keep it for three years, which model would hold its value better in percentage terms when I upgrade? I am concerned that the base iPhone 17 may begin to slow down and throttle over time, whereas the Pro Max has significantly more processing power and better cooling
