Should you buy an iPhone 15 in 2026?
At 3 years old the iPhone 15 sits in the sweet spot: the steepest depreciation has already happened, it runs the latest software without compromise, and it has years of updates ahead. This is the age we recommend most buyers target.
Apple has historically kept iPhones on the latest iOS for around six to seven years after launch, so an iPhone 15 released in 2023 can reasonably be expected to receive updates into 2029–2030.
CeX sell the same iPhone 15 at £435 today. Ours starts at £370 — a saving of £65 (15%) on the same storage and the same condition grade. (CeX price checked 28 October 2026.)

Buying a pre-owned iPhone 15: what to know
Every iPhone 15 we sell is put through a full diagnostic — screen, cameras, speakers, charging, biometrics and battery — then graded honestly as Like New or Good so the price reflects exactly what you receive. There are no surprises on arrival and no vague “fully working” claims hiding a tired battery.
Battery health is stated on each listing above (what the percentage means). If you'd rather keep your current iPhone 15 running, a battery or screen repair is often the smarter spend — get a fixed-price repair quote in seconds. Upgrading? Our trade-in portal turns your old device into instant credit.

Common questions
How much is a refurbished iPhone 15?+
A tested & certified iPhone 15 starts from £370 at Optimise Marketplace — £65 (15%) less than CeX charge for the same one (£435, checked 28 October 2026). The exact price depends on storage (128GB), colour and condition grade. Every one includes a 12-month warranty, free insured UK delivery and 30-day returns.
How old is the iPhone 15?+
The iPhone 15 went on sale in the UK in September 2023, making it 3 years old. Apple has historically kept iPhones on the latest iOS for around six to seven years after launch, so an iPhone 15 released in 2023 can reasonably be expected to receive updates into 2029–2030.
Will the iPhone 15 still get software updates?+
Yes. Based on the maker's stated policy and track record, the iPhone 15 should keep receiving updates until around 2029, so it is safe for banking apps, security patches and new features for the foreseeable future.
What does an iPhone 15 repair cost if I damage it?+
Our fixed prices for the iPhone 15 are £75 for a screen replacement and £70 for a new battery, usually done the same day in Batley. Accidental damage isn't covered by the warranty, but it's inexpensive to put right.
How much is my old iPhone 15 worth?+
We currently pay up to £335 cash for an iPhone 15 in Like New condition, with lower grades priced honestly. Get an instant quote on our trade-in page — the price is locked for 7 days.
Is a refurbished iPhone 15 worth buying?+
Yes — though "refurbished" is not quite the right word for ours. Nothing has been rebuilt or modified: these are pre-owned handsets with 100% original parts, tested and graded. A iPhone 15 bought this way performs identically to new at a significant saving. Each device is inspected and function-tested by us, graded honestly and comes with a 12-month warranty (covering hardware faults in normal use) plus 30-day returns.
Is the iPhone 15 unlocked?+
Our iPhone 15 stock is sold unlocked unless clearly stated otherwise, so it works with any UK network and with eSIM plans.
What battery health does the iPhone 15 have?+
Battery health is listed on every individual iPhone 15 listing, so you know before you buy. Every pre-owned phone we sell has at least 85% battery health, Like New and Good alike.
