When Should I Sell My iPhone 15?

Smartphone values depreciate fastest in the months following a new release. If you're planning to upgrade to the iPhone 16 or iPhone 17, now is the ideal time to sell your iPhone 15 while demand remains high.

Waiting too long can reduce your device's value as newer models flood the second-hand market.
