With Apple expected to unveil the iPhone 17 and iPhone 17 Pro as early as September 9th, current device owners are being warned that waiting too long to trade in their phones could prove costly. Rumours also suggest a super-slim iPhone 17 Air may be introduced, offering a more lightweight option.
Trade-in specialists say older models typically lose value once new devices go on sale, and this year is expected to follow the same trend. One site estimates that current iPhone models could drop by as much as £300, while premium Pro and Pro Max versions could lose between £150 and £300 within the first month after a launch.
Sam Wilson, Director at Gadget GoGo, explained: "The iPhone resale market stays the same year after year, yet most people still wait until after the new models are announced to sell their old phones. By then, it's too late, and the market becomes saturated with old models and values drop."
Wilson added: "iPhones generally retain their value better than other brands, which makes the timing of selling even more important. You're starting from a higher resale value, so the actual amount you lose by waiting can be huge."
Apple offers its own trade-in scheme, but for those considering an upgrade, it may be wise to check current device values now to secure the best price. However, the iPhone 17 is not expected to be in stores until later next month, so sellers will need a backup device in the meantime.
Details remain unconfirmed until Apple's keynote in Cupertino, California, but rumours point to a refreshed design, faster processor, improved cameras, longer battery life, new colours, and a significantly slimmer iPhone 17 Air.
