The real current price gap
New iPhone 15 (128GB): £590.00
Refurbished iPhone 15: from £339.95
That's a real, current saving of over £250 — more than 40% off the new price — for buying refurbished rather than new. This guide breaks down exactly what that saving does and doesn't cost you.

What "new" actually means for a phone that's two generations old
It's worth being clear about something that surprises a lot of buyers: the iPhone 15 is still sold brand new by retailers, sitting alongside the current iPhone 17 lineup, even though it's no longer Apple's newest release. This is completely standard — manufacturers typically keep the previous couple of generations in active new-sale distribution rather than pulling them from shelves the moment a successor launches. The £590 new price reflects this: a genuinely new, sealed, unused device, just from an earlier generation than the current flagship.
What you're actually getting for the extra £250
Buying new gets you a device with zero prior use, the absolute newest possible battery (100% health rather than a used unit's naturally lower figure), and the psychological reassurance of being the phone's first and only owner. For some buyers, that reassurance alone is worth paying for — there's nothing wrong with valuing it.
What refurbished genuinely doesn't compromise on
This is the part worth being explicit about, since "refurbished" carries an unfair reputation for some buyers: every refurbished iPhone 15 GadgetRank compares passes the same full functional check as it would coming off Apple's own production line, and comes with the same minimum 12-month warranty you'd expect buying new. The phone works identically — same chip, same camera, same software — regardless of which one you choose. The difference is purely in prior use and cosmetic condition, not capability.
The one genuine trade-off worth understanding: battery health
This is the real, honest caveat with buying refurbished over new. A brand-new iPhone starts at 100% battery health; a refurbished unit will have some genuine wear, typically guaranteed at a minimum of 80% or above by GadgetRank's compared retailers. In practice, this means a slightly shorter time between charges than a factory-fresh unit — a real difference, but one most buyers find genuinely minor compared to the saving, particularly since battery health can be checked and compared before you commit to a specific listing.
Does the saving get bigger or smaller over time?
Generally bigger. As more time passes since the iPhone 15's original launch, more refurbished stock enters the market and demand for buying it new (rather than a newer current-generation phone) continues to soften — both push the refurbished discount wider over time. If the current 40%+ saving already looks compelling, it's likely to look even more so as this generation ages further.
Is the iPhone 15 specifically a good candidate for buying refurbished?
Yes, genuinely more so than buying refurbished on the very newest current generation. The iPhone 15 is old enough that refurbished stock is plentiful and well-established, meaning better selection across grades and more competitive pricing between retailers than you'd find on a brand-new release with limited refurbished availability.
What to check before buying refurbished
Beyond battery health, confirm the specific cosmetic grade (Premium, Excellent, Good, or Fair) matches the price you're being quoted, and check that the retailer's stated warranty terms are clearly listed — every retailer GadgetRank compares should state this plainly, and if a listing is vague about warranty length or coverage, that's worth treating as a caution flag rather than assuming the best.
How this price gap compares to other iPhone generations
The iPhone 15's roughly 40% discount refurbished versus new is a genuinely useful benchmark for understanding how these savings typically develop. Older generations — the 13 and 14 — show even wider percentage gaps in our current price tracking, since they've had longer for refurbished stock to build up and for new-sale demand to soften further. The very newest generations, like the 17 range, show smaller gaps for the opposite reason: less time has passed, so less refurbished stock exists and new-sale demand remains stronger. The iPhone 15 sits in a genuine sweet spot — old enough for a substantial, well-established discount, new enough to still feel like current, modern hardware.
Considering the total cost over time, not just the purchase price
It's worth thinking beyond the upfront price difference alone. A refurbished iPhone 15 at a genuine saving of over £250 gives you real money to put toward accessories, a case, additional storage on the initial purchase if that matters to you, or simply keep. Over a typical two-to-three-year ownership period, this upfront saving generally outweighs the marginal difference in battery longevity between a new and a well-graded refurbished unit — the maths favours refurbished for most buyers who aren't specifically prioritising the reassurance of zero prior use.
Is buying refurbished from GadgetRank's compared retailers actually safe?
This is a fair, common concern worth addressing directly rather than assuming. Every retailer GadgetRank compares is a real, established UK business, not an anonymous marketplace seller — each one grades devices to a stated, consistent standard, and each one provides a genuine minimum 12-month warranty as standard practice, not an optional extra. This is meaningfully different from buying secondhand through an unregulated private sale, where none of these guarantees exist by default.
What genuinely happens if a refurbished phone develops a fault
Since every retailer GadgetRank compares includes a minimum 12-month warranty, a genuine fault occurring within that period should be covered under the same terms as a new purchase from any retailer — repair or replacement, depending on the specific issue and the retailer's own policy. This is worth checking specifically before you buy, since warranty terms can vary in exact detail between retailers even when the headline coverage period is the same.
Frequently asked questions
Is a refurbished iPhone 15 as reliable as a new one?
Functionally, yes — every refurbished unit passes the same working-order checks and carries the same minimum warranty as a new purchase. The only real difference is prior use and cosmetic condition.
Why is a two-generation-old iPhone still sold new?
Apple and its retail partners typically keep the previous couple of generations available new for buyers who want current software support at a lower price than the newest release, rather than immediately discontinuing older stock.
Will the refurbished discount on the iPhone 15 grow over time?
Very likely — refurbished discounts typically widen as a generation ages, driven by increasing stock availability and reduced demand for buying that specific generation new.
Is it worth paying the full £590 for a new iPhone 15 instead of refurbished?
Only if having zero prior use and 100% battery health from day one genuinely matters enough to you to justify over £250 extra — functionally, the phones are identical.
How do I know a refurbished iPhone 15's battery health before buying?
Check the specific listing for the stated battery health percentage — GadgetRank's compared retailers guarantee a minimum floor, typically 80% or above, and state the actual figure for each unit.
Is buying refurbished from a comparison site like GadgetRank safer than buying secondhand privately?
Generally, yes — GadgetRank's compared retailers are established businesses offering standardised grading and a guaranteed minimum warranty, protections a private secondhand sale typically doesn't include.
