iPhone owners across the UK have been issued an urgent warning to sell their devices within the next 30 days. Tech expert Sam Wilson from Gadget GoGo warns that waiting until after Apple's September iPhone 17 announcement could cost owners hundreds of pounds in lost resale value.
Second-hand iPhone values typically plummet by up to 30% within weeks of a new model being announced. Wilson said: "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."
Analysis of previous iPhone launches reveals a consistent pattern of dramatic value drops. The market becomes saturated with older models immediately after new releases, driving prices down significantly.
Biggest losses hit premium models
Pro and Pro Max versions face the steepest depreciation, potentially losing £150-300 in value within the first month after a new launch. Wilson said: "That's a lot of money they could have pocketed by acting just a few weeks earlier."
The iPhone 17 announcement is expected in mid-September, following Apple's traditional annual launch schedule. Wilson pointed out: "By then, it's too late, and the market becomes saturated with old models and values drop."
Even owners of older models like the iPhone 13 or 14 should act now rather than wait. Wilson explained: "Even if you're using an iPhone that's a few years old, you'll still see a big drop in value after the new announcement."
Consumer behaviour patterns
Social media reflects this waiting mentality, with one user posting: "waiting for iPhone 17 launch, so that iPhone 16 price drops, so that iPhone 15 price drops so that I can buy iPhone 7." According to data from Statista, iPhone models historically show varying rates of depreciation following their launch, with some premium models maintaining better value than others in the months after release.
Wilson explained that iPhones generally retain value better than Android alternatives, making timing even more crucial. Wilson said: "You're starting from a higher resale value, so the actual amount you lose by waiting can be huge."
Smart selling strategies
The expert advised starting the selling process immediately, even for those planning September upgrades. Many buyback services allow customers to lock in current prices while continuing to use their phones for several more weeks.
The growing refurbished smartphone market reflects increasing environmental consciousness among consumers. Wilson noted: "When you sell your device before values drop, you're making a smart financial decision that's also environmentally responsible."
