Just out of interest. Why did you upgrade every year? Did you actually notice a real difference between 5 and 5S or 6 and 6S? Did it change the user experience so much to justify the price? I went form 3g to 5S to 7. I probably still would have the 5S if I would not have drowned it by mistake. These phones are so extremely capable these days that I can't see that one gets to the limits of their capability within one year.
