I have iPhone 6 Plus 64GB and the most I am able to get is $450. My phone cost me $909 with tax last year. In addition I paid 100 for AppleCare+. So in total I paid $1009 for the phone and the most I am getting now is $450 on craigslist. So it seems like I am loosing $559 in value in 12 months. Whoever told you that iPhones have great resale value are lying. For $559 I could be buying brand new Nexus 6P every year and loose $250 in value at most. Granted my phone is in excellent condition and still has 2 Apple Care replacements left.
