What affects how much you get for your iPhone 18
Two identical-looking phones can be worth very different amounts. Five things move the number, and you control most of them before you send the device. Checking these before you accept a quote is the quickest way to avoid a revised offer later.
• Condition. Sealed and unused devices pay the most. PREMIUM means like-new with no visible marks. GREAT means light wear. GOOD means clear scratches or dents but fully working.
• Storage. Higher capacities pay more. The gap between 256GB and 2TB is the largest single jump on the Pro models.
• Battery health. 80% or above is required for GOOD and every grade above it. Below 80% drops you a tier.
• Network lock. Unlocked devices are worth more than locked ones.
• Box and accessories. Original sealed packaging is only needed for the NEW (sealed) grade. Every other grade prices the handset on its own. Battery health sits in Settings, then Battery, then Battery Health and Charging. ##
Where to sell your iPhone 18 for the best price
There are five realistic routes for an iPhone 18 Pro in the UK, and they trade price against effort and risk. Network trade-in is the easiest and usually the lowest, because the value arrives as credit against a contract rather than cash. High street counters pay on the spot but price for their own resale margin. Private marketplaces can pay the most on paper, though you carry the scam risk, the postage and the chargeback exposure yourself. Comparison sites list a headline figure that is often revised down once the device is inspected. Direct buyers like vendi sit in between: one quote, fixed, paid in cash. What we hold ourselves to:
• The quoted price is the paid price. No seller fees and no hidden deductions, as long as the device matches the condition you picked.
• Your quote is locked for 10 days while the device reaches us and is verified.
• £10 towards postage and a Royal Mail tracked label, emailed as soon as you accept.
• Same-day payment by bank transfer for devices arriving before 2pm. Cash to your account, not vouchers or store credit.
• Rated 4.9/5 across Trustpilot and Google, and trusted by 60,000+ vendi users.
Whichever route you pick, get at least two quotes before you commit. Values on a phone this new move week to week.
When to sell your iPhone 18
Timing changes what you get. Resale values for any iPhone are highest in the months right after launch, while supply of second-hand units is still thin and demand is high. They soften as more people upgrade and stock builds up, then drop again around the next Apple announcement. Two dates matter for iPhone 18 sellers. The standard iPhone 18 and iPhone 18e are reported for spring 2027 [confirm with team], and the next Pro generation is expected around September 2027. If you are planning to move your 18 Pro on at some point, doing it before either of those announcements protects the value. The same rule applies to the phone you are replacing. An iPhone 17 or iPhone 16 sitting in a drawer loses value every month it stays there.
