Four phones, one very tight price bracket
Samsung's current Galaxy flagship lineup is unusually tightly priced this generation — just £280 separates the cheapest and most expensive of these four phones, and two of them (the standard S26 and the S25 Edge) sit within £10 of each other. That makes this a genuinely closer decision than most flagship comparisons, where price alone usually does most of the work for you.
Here's what actually separates them.
Galaxy S26 — £590
The standard Galaxy S26 is Samsung's mainstream flagship — strong performance, a capable camera system, and Samsung's current design language, without stepping up to Plus or Ultra pricing. For most buyers who just want "the new Samsung flagship" without a specific reason to spend more, this is the sensible default.
Price: £590
Best for: Buyers who want a current Samsung flagship without paying for size or camera upgrades they won't use.
Galaxy S26 Plus — £790
The S26 Plus adds a larger screen and bigger battery over the standard S26, for a £200 premium. Core performance and the camera system are closely matched to the standard S26 — this is fundamentally a size-and-battery-life upgrade rather than a different phone underneath.
Price: £790
Best for: Buyers who specifically want a bigger screen and longer battery life, and are happy to pay £200 for those two things alone.
Galaxy S26 Ultra — £860
The S26 Ultra is Samsung's true flagship — the best camera system in the range, the S Pen stylus built in, and premium materials throughout. At £860, it's a £270 step up from the standard S26, and that gap is genuinely justified if you use the S Pen regularly or photography is a real priority for you. If neither of those apply, the jump buys less real-world benefit than the price difference suggests.
Price: £860
Best for: S Pen users, serious photography, or anyone who wants Samsung's best without compromise.
Galaxy S25 Edge — £580
The S25 Edge is the outlier of the four — a previous-generation model still on sale, distinguished mainly by an ultra-thin design that's genuinely unlike anything else in Samsung's current lineup. At £580, it's actually £10 cheaper than the standard S26, which makes it a legitimate alternative rather than just old stock being cleared out.
The decision here comes down almost entirely to whether the slim form factor specifically appeals to you. If it doesn't, the S26 is the more conventional choice at essentially the same price, with a newer chip generation behind it.
Price: £580
Best for: Buyers specifically drawn to an ultra-thin design, at a price that undercuts the newer standard S26.
Battery life across the range
Battery capacity generally scales with physical size across this lineup, which matters if all-day battery life is a genuine priority rather than a nice-to-have. The standard S26 and S25 Edge, being the more compact devices in this comparison, will typically see you through a full day of moderate use but may need a top-up on genuinely heavy days — extended gaming, hours of video streaming, or continuous navigation use.
The S26 Plus and S26 Ultra's larger bodies house bigger batteries, translating into more real-world headroom before you need to reach for a charger. If your phone use skews heavy — long commutes with constant screen time, work that keeps the phone active most of the day, or simply anxiety about running out of charge before you get home — the size step up to Plus or Ultra buys genuine peace of mind beyond just the screen and camera upgrades.
Software support and long-term value
All four phones in this comparison run Samsung's current One UI software and are covered by Samsung's multi-year update commitment, which has become genuinely competitive with Apple's iPhone support window in recent years — a meaningful factor if you plan to keep your phone for four or more years rather than upgrading every generation.
Worth noting specifically for the S25 Edge: as a previous-generation model still on sale alongside the newer S26 family, its update clock started a year earlier than the S26 line's. If long-term software support matters more to you than the immediate price saving, that's a real factor to weigh against the Edge's slightly lower price — you're getting one fewer year of guaranteed updates for a saving of roughly £10, which is arguably not much of a trade at all once framed that way.
Which should you actually buy?
- Want the safe, sensible default: Galaxy S26, £590
- Want a bigger screen and more battery, willing to pay for it: Galaxy S26 Plus, £790
- Want the best camera and the S Pen: Galaxy S26 Ultra, £860
- Want something distinctively slim, at a price below the standard S26: Galaxy S25 Edge, £580
The S Pen: the Ultra's real differentiator beyond specs
Beyond camera and screen size, the S26 Ultra's built-in S Pen deserves its own real consideration rather than being treated as a minor bonus feature. For anyone who takes handwritten notes regularly, annotates documents and PDFs on the go, or uses it for quick sketches and diagrams, the S Pen is a genuinely useful tool that no other phone in this comparison — or arguably any other phone on the market — offers built into the device itself with nowhere else to store or lose it.
If you've never used a stylus phone before, it's worth being honest that plenty of Ultra owners rarely pull the S Pen out after the first few weeks of novelty wears off. Buy the Ultra for the S Pen specifically if you already know you have a real, regular use for it — not on the assumption you'll develop one after buying.
The closeness in price across all four means this comparison genuinely comes down to what you'll use, not which one is objectively "best" — there's no wrong answer here on value alone, only on fit.
