I usually buy a $900 iPhone, sell it for $600 after a year, and buy the new iPhone for $900. So I spend around $300 to upgrade my iPhone every year.
I used to upgrade my phone after 3 years, at that point the phone becomes very outdated and it's worth is hardly $100. So it costs me around the same if I buy an inexpensive phone every year, buy an expensive phone and use it for few years, or trade up a new iPhone every year.
