Samsung Galaxy Z Fold 8 Ultra review: This is what Ultra on a foldable looks like

When Samsung applied the ‘Ultra’ suffix to its Galaxy S series, it carried a clear promise that you are getting the biggest camera, the most capable chip and the finest materials. Ultra was a statement of excess and Samsung generally kept it. But applying that same label to the Galaxy Z Fold line is a more complicated proposition because foldables operate under tighter constraints than slab phones; every millimetre of thickness and every gram of weight is a trade-off that doesn’t exist in the same way for a conventional flagship. Building an ‘Ultra’ inside something that folds in half is a different kind of engineering problem.

The Galaxy Z Fold 8 Ultra, at Rs 1,99,999 for the base 256 GB variant, is Samsung’s attempt to resolve that problem. It is a direct successor to the Fold 7, keeping the same 215 g weight and a nearly identical form factor, but upgrading virtually everything inside. The Snapdragon 8 Elite Gen 5 replaces the Snapdragon 8 Elite and the performance gap is now generational. The battery grows from 4,400 mAh to 5,000 mAh silicon-carbon and the charger steps from 25 W to 45 W, which is the quality-of-life change Fold owners have been asking for across multiple iterations now. The inner display gains Flex Titanium technology to reduce the crease and an anti-reflective coating to reduce glare. Factory calibration, as our Calman testing confirms, is reference-grade on both panels. And for the first time on a foldable, Android 17 based OneUI 9 ships out of the box.

The Fold 8 Ultra doesn’t reinvent what a foldable phone is. What it does is execute the formula at a level that makes the Ultra suffix feel well worth its name.

Design: refined, not reinvented

The Fold 8 Ultra looks immediately familiar to anyone who has held the Fold 7. It has practically the same proportions, the same Advanced Armor Aluminum frame, the same 8.9 mm folded thickness. At 4.1 mm when open, it is a hair thinner than the Fold 7’s 4.2 mm and the slightly indented side frame and revised hinge gap make it easier to get a nail under the device to unfold one-handed. These are small changes that make the daily opening ritual feel just slightly more natural.

The two meaningful structural updates are Flex Titanium and the Gorilla Glass Victus Ceramic 3 protection. Flex Titanium is a titanium alloy plate placed under the inner display, stiffening the panel assembly and making the crease noticeably less visible than on the Fold 7. It doesn’t disappear entirely and you will still feel it under your fingertip if you drag across the fold, but in normal viewing it has gone from something that registers in the first five minutes to something you largely stop thinking about. The Gorilla Glass Victus Ceramic 3 on the outer display is tougher than its predecessor, adding confidence to a panel that takes most of the daily wear.

The IP48 water resistance returns unchanged from the Fold 7. It covers splashes and brief shallow immersion, but it remains behind the IP68 ratings you find on Samsung’s own Galaxy S series. For a phone at Rs 1,99,999, this continues to feel like a compromise that Samsung could afford to address.

The cover screen is 6.5 inches: narrower and taller than the inner canvas, more phone-like than some competing foldables with wider outer displays. For one-handed typing and quick glance use, it works well. For consuming media on the outer screen, the narrower format will immediately send you to the inner panel but it also depends entirely on how you use a foldable.

Display: two panels, universal experience

The Fold 8 Ultra’s display story has two parts: the visual experience and the colour accuracy behind it. Our peak brightness test measured 2,810 nits on the main inner screen and 2,750 nits on the cover in HDR mode. For context, the Fold 7 measured 2,400 nits on the main panel and 2,480 nits on the cover in our equivalent tests. These are meaningful gains, particularly for outdoor use as both screens cut through direct sunlight with ease and the anti-reflective coating on the inner display reduces glare in ways that the Fold 7 simply couldn’t. Whether you’re reviewing photos in the open air or watching video in a bright room, the inner panel no longer fights the environment.

Fold 8 Ultra Cover Screen

Our Calman testing evaluated both panels in Samsung’s Natural colour profile, which maps SDR content to the sRGB colour space. The main inner screen returned an average DeltaE of just 0.61 across the Colour Checker suite. To put that in context, the Fold 7’s main screen averaged 1.6 in our equivalent test, which we already considered excellent. The Fold 8 Ultra’s 0.61 is reference-monitor territory as any delta under 1.0 is considered near-imperceptible, meaning what you see on this panel is about as close to the source content as consumer display technology currently allows. The maximum deviation across the entire chart was 4.81, and those outliers are in the most saturated colour regions where the human eye is least sensitive to error.

Fold 8 Ultra Main Screen

The cover screen posts an average DeltaE of 1.05, still well within the threshold that matters in real-world use. The sRGB coverage is 98.5% on the main panel and 97.2% on the cover. Samsung’s colour management properly restricts DCI-P3 coverage to the 73–79% range in Natural mode, which means SDR content is not receiving the unwanted saturation boost that plagues many OLED panels. Grayscale tracking on the main screen averages a DeltaE of 0.75 with a maximum of 1.00, keeping whites and greys neutral and free of tint. The EOTF tracking follows its target curve cleanly on both displays, preserving shadow detail without artificially crushing it.

Both displays support 120 Hz adaptive refresh under LTPO control, HDR10+ for premium streaming content and 10-bit colour depth. The full-flat inner and outer panels from the Fold 7 carry over, making edge gesture navigation and typing on the cover screen feel consistent across the whole surface.

The Fold 8 Ultra has, objectively, two of the most accurately calibrated panels currently shipping in a consumer smartphone. If colour precision matters to you, whether for photography review, video editing or simply wanting what you see on screen to match reality, this is the foldable to buy.

Performance and battery: the biggest upgrade

The Fold 8 Ultra’s AnTuTu score of 3,045,858 tells the whole performance story. The Fold 7 scored 1,929,147 and that is a 58% improvement, not year-on-year refinement. The Snapdragon 8 Elite Gen 5 for Galaxy is a different class of processor: the prime cores now run at 4.74 GHz, the GPU is the Adreno 840 running at 1.3 GHz and the UFS 4.x storage is faster than the Fold 7’s UFS 3.1.

Similarly, Geekbench returns 2,625 in single-core and 6,946 in multi-core. PCMark Work hits 21,644 (vs the Fold 7’s 18,576), 3DMark Wildlife Extreme scores 5,959, a 20% improvement over last year. These are not incremental gains, they are the kind of performance headroom that will make the Fold 8 Ultra feel fast well into its second and third year of use.

Gaming on the 8-inch inner panel is the showcase for what that power actually means. Frame rates on demanding titles like Genshin Impact and BGMI are consistent, thermal management holds up during long sessions and the sheer scale of the unfolded canvas makes the experience qualitatively different from any slab phone, regardless of raw frame count. Wi-Fi 7 support ensures that cloud gaming and high-bandwidth streaming are handled without bottleneck.

Then there is the battery something that Fold owners have waited generations to hear. The Fold 8 Ultra carries a 5,000 mAh silicon-carbon cell, up from the Fold 7’s 4,400 mAh. Our PCMark battery life test ran for 17 hours 38 minutes, up from the Fold 7’s 15 hours and 12 minutes. In daily real-world use, that translates to eight hours or more of screen-on time under mixed conditions. The Fold 7 ran out of runway at around six hours; the Fold 8 Ultra gets you through a full day and into the next.

The Fold 7 shipped with 25 W charging and this year the Fold 8 Ultra brings 45 W wired charging, reaching 67% in 30 minutes. A full charge from near empty takes under an hour. Samsung has also upgraded wireless charging to 20 W via Qi2.2 and reverse wireless at 4.5 W remains for topping up earbuds and watches. After years of watching competing flagships pull ahead on charging speed, Samsung has closed the gap in one generation.

Cameras: a credible flagship package

The camera system on the Fold 8 Ultra is the most capable setup Samsung has shipped on a foldable and our testing across outdoor daylight, high-contrast indoor scenes and close-up subjects shows a system that has grown up considerably from its predecessors.

The 200 MP main sensor at f/1.7 and 24mm handles difficult exposures that reflects mature image signal processing. In backlit outdoor scenes, highlight containment is measured in scenes with light fixtures and bright skies retain defined transitions without blown-out halos. Shadow detail in deep foliage or underlit street scenes holds without the over-brightening that makes artificially processed HDR look flat. Auto white balance under mixed LED lighting runs slightly warm but avoids the green or magenta tint shifting that still catches out some competing systems.

The zoom performance across the focal range is where the improvement from the Fold 7 is most consistent. The mid-telephoto range (2x–3x) delivers natural perspective compression with high fidelity on medium-sized subjects. At the 3x optical mark, the 10 MP telephoto handles fine textures, clean edges and minimal chromatic fringing on high-contrast outlines. Push further into the digital zoom range, and fine text and surface detail remain legible without aggressive edge ringing, even at higher crop factors.

When it comes to close-up photography, the depth falloff from the focal plane into soft blur is smooth and gradual rather than the abrupt software-cutout quality that marks lesser systems. The Fold 8 Ultra’s colour science has grown more controlled, foliage stays lively without turning neon, saturated primaries like crimson red retain tonal gradients without banding and complex indoor hues maintain accuracy across varying light falloff.

The 50 MP ultrawide at f/1.9 is a significant upgrade over the previous generation. A wider field at a faster aperture means more versatile low-light and landscape shooting, and the colour consistency between the ultrawide and the main sensor is well-managed.

The one limitation that persists is the 10 MP telephoto in low light. This was the Fold 7’s weak point in the zoom system and the Fold 8 Ultra carries the same. At 3x optical in poor light, detail drops, noise increases and dynamic range tightens. It remains serviceable, but it is the area where the gap to the best camera phones in the market is most visible.

Software and productivity: the full canvas

The Fold 8 Ultra ships with Android 17 and One UI 9, with Samsung committing to seven major OS updates and correspondingly long security patch support. The software experience continues to be the area where the foldable form factor earns its price beyond the hardware.

Split-screen multitasking, app continuity between the outer and inner displays, Flex Mode for using the phone as a mini laptop, and Samsung DeX for a desktop interface over USB or wirelessly remain the productivity tools that slab phones can only approximate. One UI 9 makes these workflows feel more integrated and less deliberate than in earlier versions: the transitions between modes are smoother, app memory management has improved, and the taskbar in DeX mode handles multi-app sessions with less friction.

UWB support enables precise spatial awareness for Samsung’s device ecosystem. Bluetooth 6.0 is the latest version of the standard, and Wi-Fi 7’s tri-band support means the Fold 8 Ultra is not going to be the bottleneck in any near-future networking scenario.

Verdict: earns the Ultra badge

The Galaxy Z Fold 8 Ultra raises its starting price by Rs 25,000 over the Fold 7. What that buys you is a device where almost every meaningful limitation of last year’s model has been addressed at once. The processor is generationally faster, the battery is larger and charges twice as quickly, the crease is less intrusive, the display calibration is reference-grade, and the ultrawide camera has been properly upgraded. Taking any one of those improvements in isolation might not justify the price step. Taking all of them together, it does.

There are still things the Fold 8 Ultra doesn’t do. It still is IP48 certified not IP68 and at this price that remains a concession. The telephoto camera in low light is not best-in-class and won’t be until Samsung solves the optical zoom physics that this form factor constrains. There’s still no S Pen support, but this is a known trade-off of the foldable category, not failures specific to this device.

What the Fold 8 Ultra gets right is the thing that matters most for a device at this price: it feels a complete foldable phone. The Fold 7 was the foldable that finally felt like a phone. The Fold 8 Ultra is the foldable that finally feels like a flagship foldable. For buyers coming from the Fold 7, the battery and charging upgrade alone is a compelling reason to consider it. For buyers entering the foldable category for the first time, this is the most polished and capable version of Samsung’s unfolded vision to date. The Ultra label took eight generations to attach to a Fold, but it was worth the wait.
