Samsung Galaxy Z Fold 8 Ultra Review: Is ‘Ultra’ Worth Paying For?

Verdict: A Superb Foldable, But a Modest ‘Ultra’

The Samsung Galaxy Z Fold 8 Ultra is a book-style foldable phone that adds a larger battery, faster charging, a higher‑resolution ultrawide camera and a thinner hinge to the Z Fold 7 formula while introducing Samsung’s ‘Ultra’ branding for its top-tier foldable line. From a buyer’s point of view, though, this Galaxy Z Fold 8 Ultra review comes down to a simple verdict: the hardware is excellent, but the upgrade is incremental and the ‘Ultra’ label oversells what you get for the extra money. Samsung has quietly raised the starting price to £1,899 for the 256GB model, £100 more than last year’s equivalent, with 512GB and 1TB options costing £2,069 and £2,319 respectively. Those figures place it firmly in luxury territory, where small gains have to feel transformative. For most people, they don’t.

Design, Build and the ‘Thinnest Foldable’ Pitch

Visually, the Z Fold 8 Ultra leans heavily on refinement rather than reinvention. The Flex Titanium design adds a titanium plate under the main display to disperse stress more evenly, which helps minimize the crease and make the hinge slimmer and smoother in daily use. The ArmorFlex hinge structure is billed as sturdier and more reliable, although hands-on impressions suggest it feels similar to the Z Fold 7 rather than dramatically different. The phone measures 73 x 8.9 x 158mm when folded and 143 x 4.1 x 158mm when opened, weighing 215g. In short, it is thin for a big foldable, but still substantial in the pocket. Color finishes—Graphite, Violet Shadow, Cream and the Samsung‑exclusive Green Shadow—subtly reinforce the premium positioning without changing the core silhouette. If you care most about a more polished foldable design and a cleaner crease, this is where the Ultra earns part of its name.

Performance, Battery and AI: High-End, Not Game-Changing

Under the hood, the Z Fold 8 Ultra has the same 4.74GHz Snapdragon 8 Elite Gen 5 for Galaxy chip used in Samsung’s top bar phones, backed by up to 16GB of RAM and 1TB of storage. According to one hands-on report, “power is likely to be unmatched, battery life should be better thanks to the power-efficient processor and higher battery capacity.” The new 5,000mAh Si‑Ca battery is a clear step up from the Z Fold 7’s 4,400mAh pack, and wired charging now reaches 60W while wireless climbs to 25W Qi2.2. In practice, that should mean a comfortable full day of heavy use and meaningfully faster top-offs. Software is based on Android 17 with One UI 9 and seven years of updates, with foldable‑aware AI features like Now Nudge and tools such as Gemini Notebook that can summarise audio and PDFs into detailed overviews. These are welcome additions, but they’re not exclusive enough to define the Ultra experience.

Cameras and Competition: Where ‘Ultra’ Falls Short

On paper, the camera array looks impressive: a 200MP primary sensor, a 10MP 3x telephoto, a new 50MP ultrawide replacing last year’s 12MP unit, plus two 10MP selfie cameras. The main camera now supports HDR for more true‑to‑life images, and Samsung’s ProVisual Engine aims to improve Nightography and skin tones in video. However, the telephoto hardware is unchanged from the Z Fold 7, and rivals are moving ahead. Competing foldables offer higher‑resolution zoom lenses or longer optical ranges, including a 64MP and 50MP telephoto on rival models and a 5x optical zoom on another flagship foldable. Likewise, durability trails direct competitors: the Z Fold 8 Ultra keeps its IP48 rating, while some alternatives reach IP68 or even IP69 for full dust protection. With this kind of money being laid down, you expect no obvious weak links, yet telephoto and dust resistance are two clear ones.

Value and Branding: Is the Z Fold 8 Ultra Worth the Jump?

The central question for any foldable phone upgrade worth considering is whether the Z Fold 8 Ultra’s changes justify its higher price and new status in Samsung’s line-up. The starting price of £1,899 for 256GB is £100 higher than the Z Fold 7’s base model, with the larger capacities stepping up accordingly. Another hands-on notes that the biggest improvements—50MP ultrawide camera, larger battery, faster charging and a slightly thinner design—“don’t seem like enough to warrant that new ‘Ultra’ branding or the associated $200 price jump.” It is telling that if last year’s phone had carried the Ultra badge, the current one might feel like a routine update rather than a flagship leap. Against increasingly competitive foldables that match or beat it on zoom and durability, the Z Fold 8 Ultra looks less like a clear-cut top choice and more like a safe, polished upgrade for devoted Samsung foldable owners.

• Buy the Samsung Galaxy Z Fold 8 Ultra if you want Samsung’s most refined book-style foldable with a cleaner crease and premium finishes and are willing to pay a higher price for incremental polish.
• Skip the Samsung Galaxy Z Fold 8 Ultra if you expected its ‘Ultra’ branding to bring dramatic camera or durability gains over the Z Fold 7 and prefer meaningful hardware leaps before upgrading.
• Buy the Samsung Galaxy Z Fold 8 Ultra if you value top-tier performance, a 5,000mAh battery, faster charging and long-term software support more than you care about telephoto specs or dust resistance.
• Skip the Samsung Galaxy Z Fold 8 Ultra if you are shopping purely on Z Fold 8 Ultra price value and can find rival foldables with stronger zoom cameras or better IP ratings at similar or lower cost.
• Buy the Samsung Galaxy Z Fold 8 Ultra if you are already deep into Samsung’s ecosystem, coming from a much older foldable phone, and want the best Samsung Ultra foldable comparison option without switching brands.
• Skip the Samsung Galaxy Z Fold 8 Ultra if you own a Z Fold 7 and your main interest is a foldable phone upgrade worth its price jump, because the improvements feel evolutionary rather than transformative.
