MILLIONS of iPhone owners are being warned to sell up fast, with experts predicting a shock drop in mobile values of up to £300 in just days.
Apple iPhones usually hold their value, meaning you can flog your old one for a tidy sum when it’s time to upgrade.

But a top second-hand tech firm has warned prices could plunge by as much as 30% once the iPhone 17 drops.
Sam Wilson, boss at Gadget GoGo, has urged iPhone owners to flog their handsets now if they want top dollar for their next upgrade.
“You’ve got just 30 days before the value starts to tank,” he warned.
“Every year, people hang on until after Apple’s big reveal – and by then it’s too late. The market’s flooded with old models and prices nosedive.”
Why the shock fall?
Wilson said simply announcing a new iPhone is enough to make older ones plummet in value, with Pro and Pro Max handsets losing £150–£300 in the first month after launch.
“That’s cash straight out of your pocket if you wait,” he added.
So if you’ve got an iPhone 16 Pro or Pro Max and plan to flog it to fund the shiny new iPhone 17, you might want to move fast.
Even older models like the iPhone 13 (2021) or iPhone 14 (2022) could bag you more cash now than in a month’s time, warns Wilson.
“Even if your iPhone’s a few years old, the value will take a hit the second Apple drops its new one,” he said.
Rumour has it the iPhone 17 range – including Pro, Pro Max and a wafer-thin ‘iPhone 17 Air’ – will be unveiled on September 9, with pre-orders from September 12 and on-sale date of September 19.
That gives you just 30 days to cash in before prices tumble.
“Get the selling ball rolling now – even if you’re eyeing up an upgrade in September,” Wilson urged.
“Plenty of buyback sites let you lock in today’s price and keep your handset for a few more weeks.”
With Brits hanging onto their mobiles for longer as yearly upgrades lose their sparkle, flogging your iPhone now could mean pocketing far more cash than if you wait.
And you don’t have to splash out on a pricey iPhone 17 either – the money could go towards a refurbished or second-hand model and still leave change in your pocket.
iPhone tricks to try today
Here are some of the best…
- Typing cursor – When typing, hold down the space bar to turn your keyboard into a trackpad, letting you move around words and sentences more easily
- Close all Safari tabs – To do this in one go, simply hold the overlapped squares in the bottom right-hand corner, and press close all tabs
- Delete lots of photos quickly – Hold down on a photo and then drag your finger diagonally in Photos to select lots of images at once, then hit delete
- Convert currency quickly – Swipe down from the top of your Home screen (or swipe left to right on an iPhone X or later model), then tap in the bar and type a currency (like $200) and it will automatically covert to your local currency
- Check if you’re due a battery upgrade – Batteries inside smartphones degrade over time. Just go to Settings > Battery > Battery Health, and check out the Maximum Capacity reading. Generally a battery is considered worn when you’re down to 80% capacity. If you’re below, you can buy a battery swap from Apple
- Move apps around faster – Hold an app until it starts wiggling, then (while still holding) tap other apps, causing them to stack so you can move them around easier
iPhone 17 features
Apple is cooking up huge design changes for this year’s big iPhone release – including tempting tweaks to the battery and screen.
Apple is expected to unveil as many as four new iPhone models.
We are expecting the lot to include a premium iPhone 17 Pro smartphone, an upgrade on the rumoured iPhone 17.
Expert Apple blog MacRumors revealed the changes we’re expecting, including a larger battery.
This will reportedly be made possible thanks to a slightly thicker design.
iPhone 16 models were hailed for their impressive battery life (including in our iPhone 16 review), but the iPhone 17 Pro could offer even more juice.
Apple is reportedly working on a more scratch-resistant screen.
Apple may be creating a new anti-reflective coating for the display that makes it tougher.
So, hopefully your screen will stay pristine for longer, giving you better resale value when you’re done with it.
Another quirky design change is the claimed move to a rectangular camera bump.
On current iPhone Pro models, there’s a raised square on the top-left of its rear casing where the camera lives.
But the iPhone 17 Pro could see this bump stretch right across the back of the handset.
It’s still expected to only feature three cameras, keeping the current triangle layout.
It’s rumoured that we’ll see an upgraded 24-megapixel selfie camera (up from the current 12 megapixels).
That’s in addition to the reported 48-megapixel telephoto camera on the back, which would be an increase from the 12-megapixel zoom lens on the iPhone 16 Pro.
Other rumoured tweaks include a new aluminium frame (swapping away from titanium), an upgrade to 12GB of RAM, better cooling, a more powerful Apple A19 Pro processor, and an Apple-built Wi-Fi 7 chip for connecting to the internet.
