Should you buy a Galaxy S23 in 2026?
The Galaxy S23 is now a value buy. It handles everything day-to-day — messaging, banking, cameras, streaming — but it is more than three years old, so check the battery-health figure on the listing and treat it as a two-to-three-year phone rather than a five-year one.
Samsung committed the Galaxy S23 to four Android version upgrades and five years of security patches, so it stays protected until around 2028.

Buying a pre-owned Galaxy S23: what to know
Every Galaxy S23 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 Galaxy S23 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.

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 Galaxy S23 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.

Our Galaxy S23 stock is sold unlocked unless clearly stated otherwise, so it works with any UK network and with eSIM plans.
What battery health does the Galaxy S23 have?+
Battery health is listed on every individual Galaxy S23 listing, so you know before you buy. Every pre-owned phone we sell has at least 85% battery health, Like New and Good alike.
