iPhone owners urged to sell current models ASAP to avoid 30% value drop: 'if you’ve got a Pro or Pro Max, waiting until after the launch can be particularly costly'

Apple's upcoming iPhone releases could cause a significant drop in the value of current models, potentially by as much as 30%, according to Sam Wilson, Director at Gadget GoGo. If you own an iPhone and are planning to upgrade soon, it may be wise to sell your existing device now rather than waiting for the launch of the iPhone 18 series.

This drop in value is especially pronounced for high-end models such as the Pro and Pro Max, with estimates suggesting that prices could plummet by £150 to £300 within weeks of the new models' release. Even older iPhone models could experience a noticeable decline in value once the newer versions hit the market. While this can present issues if the desired upgrade isn't yet available, Wilson suggests beginning the selling process now, even if an upgrade isn't planned until September.

Many buyback services allow users to lock in a price today and retain their current device for a few more weeks. This issue isn't limited to iPhones; other brands like Samsung also experience a drop in pre-owned prices after new models are launched. Samsung's next flagship phone is not expected until early or mid-September, providing less than 30 days before the value of current Samsung Galaxy S26 models could drop significantly.
