iPhone is Apple's most popular product. Because it can be used for many years, it devalues itself less quickly than other brands' cell phones. It is therefore an interesting second-hand product: iPhones X, XS, XR as well as iPhones 11 and 12 are very much in demand. Older models (iPhone 7, iPhone 8) keep a certain value.
