Yes — the Samsung Galaxy S23 Ultra remains a sound refurbished buy in 2026, provided you understand it now sits three generations behind Samsung's current flagship. It still runs a genuine 2023 flagship chipset, a 200MP camera system with two telephoto lenses, and a built-in S Pen that neither the Galaxy S23 nor S23+ offer, all backed by The Tech Gadgets' 12-month warranty and 30-day UK returns. At current refurbished pricing, it undercuts a newer Galaxy S24 Ultra or S25 Ultra while keeping most of what made it a flagship at launch. The real question isn't whether the hardware still works — it's whether the S Pen and long-range zoom matter enough to choose the Ultra over the smaller, cheaper S23 or S23+.
Key Takeaways
- The refurbished Samsung Galaxy S23 Ultra is available in 256GB, 512GB and 1TB, with all four condition grades (Like New, Excellent, Very Good and Fair) currently listed. Check the product page for live stock and today's price.
- It runs Samsung's Snapdragon 8 Gen 2 for Galaxy chipset, the same worldwide including UK units, paired with a 200MP main camera, 12MP ultrawide, and dual telephoto lenses offering 3x and 10x optical zoom.
- Samsung's own support documentation confirms four major Android OS upgrades and five years of security updates for the S23 series, extending security patches to roughly 2028.
- The S23 Ultra is the only phone in the S23 range with a built-in S Pen, and it uses an Armor Aluminium frame rather than the titanium Samsung introduced a generation later with the Galaxy S24 Ultra.
- The Tech Gadgets backs every unit with a 12-month warranty covering manufacturing defects and functional faults (battery, physical, water and electrical/short-circuit damage excluded), plus a 30-day return window from delivery.
- Samsung no longer sells the Galaxy S23 Ultra new, so refurbished stock is effectively the only route to this specific phone in the UK in 2026.

Quick Verdict: Is It Worth Buying in 2026?
Yes, for buyers who specifically want the S Pen, the longest zoom range in Samsung's S23 line-up, or the highest-resolution camera available in this range. The Samsung Galaxy S23 Ultra still handles everyday use comfortably on the Snapdragon 8 Gen 2 for Galaxy, its 200MP camera and dual telephoto lenses remain genuinely capable, and Samsung's four-year OS upgrade and five-year security commitment means it still has patch coverage ahead of it. It doesn't suit buyers chasing the newest chipset, a titanium build, the fullest current Galaxy AI feature set, or an unworn battery under full manufacturer warranty. Check current condition and storage availability before deciding.
Who Should Buy This Phone
The Samsung Galaxy S23 Ultra suits buyers who want a built-in S Pen and the longest camera zoom range in the S23 family, and who are comfortable buying a previously-owned, professionally graded device instead of new. It's a good fit if you photograph at a distance often — the 10x periscope telephoto has no equivalent on the standard S23 or S23+ — or if you use the S Pen regularly for notes, sketching or signing documents. It also suits anyone upgrading from an older Galaxy Note who wants a noticeable step up without paying Galaxy S24 or S25 Ultra prices.
Who Should Skip This
Skip the Samsung Galaxy S23 Ultra if you want a titanium frame — Samsung didn't introduce that until the Galaxy S24 Ultra — or the newest chipset and fullest current Galaxy AI feature set. It's also not the right choice if you need a sealed, unused device with a full manufacturer warranty and an unworn battery, since the warranty here explicitly excludes battery wear. And if you don't use a stylus or shoot much long-range zoom, the Galaxy S23 or S23+ covers the same core experience for typically less.
Performance
Day-to-day performance on the Samsung Galaxy S23 Ultra is smooth and dependable rather than cutting-edge. Samsung specifies the Snapdragon 8 Gen 2 for Galaxy chipset across every S23 Ultra sold worldwide, including UK units — there was no regional Exynos split for this generation — and it comfortably handles browsing, messaging, camera processing and most mobile gaming without strain. It won't match the newest silicon in raw benchmark terms, but very few everyday tasks need that headroom, and anyone coming from a phone three or more years old will feel a significant step up.
Camera (200MP System)
The Samsung Galaxy S23 Ultra's camera system is the standout reason to choose it over the rest of the S23 range. It uses a four-lens rear array: a 200MP wide sensor, a 12MP ultrawide, a 10MP telephoto with 3x optical zoom, and a 10MP periscope telephoto with 10x optical zoom, backed by a 12MP front camera. Having two distinct telephoto focal lengths gives compositional flexibility the standard S23 and S23+ don't offer at all — both share a single 50MP wide, 10MP 3x telephoto and 12MP ultrawide triple system with no long-range option. For anyone who photographs regularly at a distance, the difference is immediately usable rather than a spec-sheet curiosity.
Battery
Samsung fits the Galaxy S23 Ultra with a 5,000mAh battery and 45W wired charging — the largest cell and fastest charging speed anywhere in the S23 range. On a new unit that comfortably covers a full day of typical use. What a specific refurbished unit's battery health looks like after previous ownership is a separate question the listing doesn't answer — see Battery Condition Reality below.
Software Longevity
The Samsung Galaxy S23 Ultra launched in February 2023 running One UI 5.1 on Android 13, and Samsung's own support documentation confirms the S23 series is eligible for four major Android OS upgrades and five years of security updates in total — extending security patch coverage to roughly 2028. That is a shorter commitment than the seven-year policy Samsung introduced with the Galaxy S24 series, so don't assume the two generations carry identical software runway — check Samsung's own specifications page for the exact policy attached to the model you're buying.
Build Quality
The Samsung Galaxy S23 Ultra is built on an Armor Aluminium frame, not titanium — Samsung didn't introduce a titanium frame until the Galaxy S24 Ultra arrived a generation later. Front and back glass is Gorilla Glass Victus 2, and the phone carries an IP68 rating for dust and water resistance, tested under Samsung's own lab conditions. It remains a solidly built, premium-feeling phone despite the titanium upgrade arriving a generation later. Cosmetic condition on any individual refurbished unit depends on the grade you buy — see Condition Grading Explained below for what's actually in stock.
Display
Samsung specifies a 6.8-inch Dynamic AMOLED 2X display on the Galaxy S23 Ultra, with a 120Hz adaptive refresh rate and Gorilla Glass Victus 2 protection. In everyday use, that combination of size, brightness and smooth scrolling still holds up well against current mid-range phones and even some current flagships — it's the same panel size as the Galaxy S24 Ultra and S22 Ultra, so stepping across from either won't feel like a downgrade.
S Pen
The Samsung Galaxy S23 Ultra is the only phone in the S23 range with a built-in S Pen silo — a meaningful differentiator, since neither the standard S23 nor S23+ support stylus input at all. The S Pen carries over the same Bluetooth-enabled Air Actions remote-control gestures from the Galaxy S22 Ultra; Samsung didn't remove S Pen Bluetooth functionality until the Galaxy S25 Ultra, two generations later, so this S23 Ultra retains full Air Actions support. Whether the physical S Pen and original box contents are included with a specific refurbished unit isn't confirmed on the product listing, so check with The Tech Gadgets before ordering if this matters to you.
Refurbished vs New
Samsung no longer sells the Galaxy S23 Ultra new through UK retail — it's now three generations behind Samsung's current flagship, and new stock of a phone this old is scarce to non-existent at mainstream retailers. Buying refurbished gets you flagship-level camera hardware, a large AMOLED display and a built-in S Pen for meaningfully less than any current flagship, at the cost of a shorter software runway, no factory-sealed battery guarantee, and the condition variation that comes with any pre-owned device. If you'd rather stay within the same product family but want more update life, our Galaxy S24 Ultra buying guide and our Galaxy S23 Ultra vs S24 Ultra comparison cover the trade-offs against the next generation up.
Compare Storage & Colour Options
Condition Grading Explained
The Tech Gadgets grades refurbished phones into four cosmetic tiers: Like New, Excellent, Very Good and Fair. At the time of writing, all four grades are currently listed for the Samsung Galaxy S23 Ultra, across all three storage tiers and all eight available colourways (Cream, Lime, Lavender, Phantom Black, Red, Graphite, Green and Sky Blue). Check the product page for live stock on the exact grade, storage and colour you want — a lower grade may suit your budget better. Exact cosmetic criteria separating the four grades aren't published in detail, so ask before ordering if the level of wear matters to you. Every grade goes through the same functional testing — the grade reflects appearance, not reliability.
| Storage | Stock |
|---|---|
| 256GB | In stock |
| 512GB | In stock |
| 1TB | In stock |
Pricing and stock levels can change — always check the live variant selector on the product page for the exact configuration you want.
Battery Condition Reality
The product listing does not state a battery health percentage for individual units, which is standard practice across the refurbished phone market rather than something specific to this seller. If battery longevity matters to how you'll use the phone — heavy navigation, gaming or hotspot use — ask The Tech Gadgets directly before ordering, and remember the 12-month warranty explicitly excludes battery wear.
Warranty Considerations
The Samsung Galaxy S23 Ultra comes with a 12-month warranty from The Tech Gadgets covering manufacturing defects and functional faults, excluding battery wear, physical damage, water damage and electrical/short-circuit damage. In practice: if something stops working through no fault of your own, you're covered; if you drop it, get it wet, or the battery degrades with normal use, you're not. You also have 30 days from delivery to return the phone — use it to properly test the screen, all four rear cameras, the S Pen, wired charging, and SIM and network connectivity.
