Want to sell iPhone before iPhone 18 hits UK shelves? You’re in the right place — and the right window. Apple is set to unveil the iPhone 18 Pro, iPhone 18 Pro Max and the iPhone Fold in September 2026, and your current iPhone is about to lose a significant chunk of its resale value the moment that keynote ends. If you plan to upgrade, sell, or simply cash in an unused device sitting in your drawer, the next 12 weeks are the sweet spot to sell iPhone before iPhone 18 launches.
This guide walks you through exactly when to sell your iPhone in Bristol, how much value you stand to lose if you wait too long, and how to lock in the highest possible cash offer at Phone Craft before the market shifts.

Based on consistent supply-chain reporting from MacRumors, Bloomberg and Apple analysts:
This is the first time Apple has split its iPhone lineup across two seasons, which means the resale market gets two hits: one in September 2026 when the Pro line arrives, and a second in spring 2027 when the standard models follow.
For anyone holding an iPhone 17 Pro, 17 Pro Max, 17, 16 Pro, 16 Pro Max, or 16, the September 2026 launch is the one to beat.
This is the number that makes most people wish they’d sold sooner. Industry data from UK trade-in services and second-hand markets consistently shows the same pattern:
| Time after new iPhone launch | Average value drop |
|---|---|
| 1 week before launch | Baseline (peak resale value) |
| 2 weeks after launch | −10% to −15% |
| 1 month after launch | −15% to −20% |
| 3 months after launch | −20% to −30% |
| 6 months after launch | −30% to −40% |
In real money: an iPhone 17 Pro Max in Grade A condition that fetches around £700 today might be worth closer to £500–£550 by Christmas 2026. That’s £150+ of value gone — just by waiting.
The drop is even steeper for Pro and Pro Max models, because they share a direct upgrade path with the new iPhone 18 Pro line. Standard and “e” models lose value more slowly, but they still lose it.

If you want maximum cash, here’s the timeline to stick to:
The market hasn’t reacted yet. Buyers like us are still paying peak prices because we’re sourcing stock for the autumn rush. This is the highest-value window.
Prices start to soften as rumour-driven sellers flood the market. You’ll still get a fair offer, but expect 5–10% less than today.
Apple’s keynote happens. Within days, resale values drop sharply across all models. This is the worst possible time to sell.
Values continue dropping into Christmas as more sellers offload their old phones in favour of the iPhone 18.
If you’re in Bristol and even thinking about selling your iPhone this year, do it before September. You’ll be glad you did.
Resale value depends on five factors:
Our free online quote tool takes 60 seconds and gives you a real, honest valuation — no email signup, no sales pitch. Try it before you read another sentence:
Every iPhone has a resale floor — but some are much more sensitive to the iPhone 18 launch than others.
Even older models like the iPhone 11, XR, XS and X still have decent resale value at Phone Craft — but their prices are more stable, so the iPhone 18 launch will have less of an immediate impact.
If you’re upgrading directly to the iPhone 18, you’ve got two routes:
| Apple / EE / O2 / Vodafone Trade-In | Sell to Phone Craft Bristol | |
|---|---|---|
| Offer value | Often 30–50% below true market | Pays top market rate |
| Payment | Credit only — tied to a new device | Cash or bank transfer, your choice |
| Timeline | Linked to your upgrade order | Same-day payment |
| Broken phones | Frequently refused | We buy broken devices too |
| Negotiation | None — algorithm-driven | Honest, face-to-face inspection |
Selling for cash to a local Bristol shop and then buying the iPhone 18 separately (whether new or refurbished) almost always nets you more money. We’ve seen customers walk out £150–£300 better off versus what the networks were offering them.
A few simple steps before you walk into our Bristol shop can mean a noticeably higher offer:
Settings → Battery → Battery Health. Anything 90% or higher keeps you in the top condition bracket.
A quick wipe with a microfibre cloth makes scuffs look less prominent under inspection light.
Original box, cable and (if you still have it) the EarPods adapter all bump the offer slightly. Not essential, but it adds up.
Settings → [Your name] → Sign Out. We can’t buy a phone with Find My still active, so this is the single most important step.
Settings → General → Transfer or Reset iPhone → Erase All Content and Settings. Wipes the device cleanly and speeds up the inspection.

Online buyback sites like Music Magpie, Mazuma Mobile and CeX advertise quick offers — but most Bristol customers regret using them:
At Phone Craft on 58A Union Street, BS1 2DL, we do the opposite:
Apple is widely expected to launch the iPhone 18 Pro, iPhone 18 Pro Max and iPhone Fold in September 2026, with UK pre-orders mid-month and general release in late September. The standard iPhone 18 and 18e are expected in spring 2027.
Sell now. The iPhone 17 series will see the steepest value drop after the iPhone 18 Pro launches in September. You stand to lose 15–25% of its current value within weeks of the new keynote.
Yes, but less than today. Expect a 10–20% drop in iPhone 16 resale values within 1–3 months of the iPhone 18 release. Selling before September 2026 is the safer play.
Yes — we buy iPhones with cracked screens, faulty batteries, water damage, and most other issues. Get an honest quote on our Sell Your Device page.
Selling to Phone Craft almost always pays more — typically £100–£300 more than Apple’s trade-in scheme for the same device, and you receive cash on the spot rather than store credit.
Around 20 to 30 minutes, including the device inspection. You walk in with the phone, walk out with cash or a same-day bank transfer.
Your iPhone, charger (if you have it), and a valid UK photo ID (driving licence or passport).
The iPhone 18 launch is just over three months away. Every week you wait is potential cash lost from your pocket. Get a free, no-obligation quote in 60 seconds — and if you like the price, drop in to 58A Union Street, BS1 2DL the same day.
