Samsung Z Fold 8 Hands-On: The Compact Foldable Is the Biggest Surprise

Samsung unveiled three new foldable phones in one go. Ranked by how interesting they are in ascending order: the Z Flip 8, Z Fold 8 Ultra, and the most unexpected of all — the Z Fold 8. This generation of foldables appears to follow Samsung's characteristically steady approach, but hidden within the product positioning and hardware details are some intriguing strategic moves.

Z Flip 8: A Safe, Incremental Upgrade

The new clamshell foldable Z Flip 8 looks very similar to last year's Flip 7, but it's thinner and lighter — 8 grams lighter and 0.5mm thinner. This is the kind of measured upgrade everyone expected.

On the performance front, it's powered by the Snapdragon 8 Elite Gen 5 for Galaxy chip, matching the S26 series and sharing the same performance, imaging pipeline, and NPU. The Snapdragon 8 Elite Gen 5 for Galaxy is Qualcomm's flagship mobile processor custom-built for Samsung, manufactured on TSMC's 3nm process. The "for Galaxy" suffix indicates deep co-engineering between Samsung and Qualcomm, with dedicated optimizations for GPU frequency, NPU scheduling strategies, and ISP (Image Signal Processor) pipeline tailored to Samsung's One UI system and camera algorithms. The NPU (Neural Processing Unit) is one of the core selling points of current flagship chips, handling on-device AI tasks including real-time photo semantic segmentation, AI noise reduction, text summarization, and voice recognition — enabling these computations to run locally without uploading to the cloud.

There are also some detail improvements, such as chamfered inner edges that make the phone easier to open and close, and the cover screen interaction now feels more like a regular screen — swipe down from the left for notifications, from the right for quick settings, and swipe up from the bottom to open apps.

For users holding a model from one or two generations ago, 8 grams lighter and 0.5mm thinner isn't enough to justify an upgrade, but this is Samsung's signature "slow and steady" iteration approach.

Z Fold 8 Ultra: The Crease Problem Finally Gets an Answer

The large-screen foldable flagship has reached its eighth generation. For years, Samsung has taken an incremental approach on this product line, to the point where despite having the earliest start, more aggressive competitors have gradually caught up or even surpassed it.

The Z Fold 8 Ultra is still a modest iteration: new Snapdragon chip, thinner and lighter than the previous generation. On the camera front, the ultrawide has been upgraded to a new 50MP sensor capable of 8K video, the main camera remains at 200MP, and the telephoto is unchanged.

But the biggest change lies in the improved hinge and inner display. Previously, reviewers noted in their "peak foldable" video that the OPPO Find N6 had almost completely eliminated visible creasing — an impressive feat that made Samsung look somewhat behind. This time, Samsung has added a titanium alloy film and titanium metal backplate behind the OLED screen, taking a major step forward in eliminating the center crease.

The crease on foldable screens is essentially a permanent indentation caused by repeated deformation of the flexible OLED panel at the hinge bend point, involving the mechanical stress distribution across multiple layers — including the polarizer, touch layer, OLED emissive layer, TFT backplane, and protective film. There are three main technical approaches to eliminating creases: first, increasing the hinge bend radius (waterdrop hinge) to create a gentler curve; second, improving the screen substrate material with better elastic recovery to reduce plastic deformation; third, adding support structures behind the screen to distribute stress. Samsung's titanium alloy film and titanium metal backplate follow the third approach — titanium alloy combines high strength with appropriate elastic modulus, providing more uniform support for the screen in its unfolded state, distributing localized stress at the bend point across a larger area, thereby significantly reducing the visual appearance of the crease.

If OPPO's performance scores a 10, the Z Fold 8 Ultra comes in at about 8 to 8.5. While it hasn't reached OPPO's level, it's a massive improvement compared to last year's roughly 5 out of 10. Combined with a new anti-reflective coating and peak brightness of 3000 nits, the crease is nearly imperceptible when the screen is on and displaying content.

On the battery front, Samsung has introduced silicon material in a foldable battery for the first time. Traditional lithium batteries use graphite as the anode material, whose theoretical energy density is approaching its physical limit. Silicon anode material has a theoretical lithium storage capacity roughly 10 times that of graphite, enabling more charge to be stored in the same volume — thus increasing capacity without enlarging the physical battery size. However, silicon undergoes approximately 300% volume expansion during charge-discharge cycles, which can lead to electrode pulverization and capacity degradation. Industry solutions include nano-silicon particles, silicon-carbon composites, and silicon suboxide as compromise approaches. Samsung has adopted a relatively conservative silicon-carbon hybrid approach (with lower silicon content) to balance energy density improvement with cycle life stability, while manufacturers like OPPO have pursued more aggressive higher-silicon-content approaches. Although the implementation is far less aggressive than competitors, this is still the largest battery ever in a Samsung foldable — 5000mAh. Charging speeds have finally been updated too: wired goes from 25W to 45W, and wireless from 15W to 20W.

Z Fold 8: A Brilliant Product Positioning Move

The real story is this new Z Fold 8 that Samsung added to its lineup. Behind it lies a remarkably forward-thinking positioning strategy.

The industry widely expects Apple to launch its first foldable iPhone within a few months, reportedly in a shorter, wider "passport" aspect ratio. Interestingly, the industry briefly experimented with this passport form factor years ago — the original OPPO Find N and first-generation Pixel Fold both had this shape — but the entire industry gradually shifted toward Samsung's "candy bar" form factor: when closed it looks like a slightly tall regular phone, and when opened it reveals a nearly square large screen.

This form factor debate is fundamentally about different trade-offs between the folded cover screen aspect ratio and unfolded inner screen use cases. The "candy bar" form factor folds into a tall, narrow traditional phone ratio (roughly 23:9), with the cover screen able to run most portrait-mode apps like a regular phone, while the unfolded inner screen is nearly square, ideal for multi-tasking split screen. The "passport" form factor folds shorter and wider (close to 16:10), with the cover screen already offering good horizontal viewing, while the unfolded inner screen approaches 4:3, better matching traditional tablet and book reading proportions. One reason early manufacturers abandoned the passport form factor was that the folded width was too large for comfortable pocket carry. Apple's reported choice of this form factor likely relates closely to the 4:3 content adaptation advantage of its iPad ecosystem.

To counter the potential narrative that Apple's "passport-style foldable is innovative," Samsung simply released its own passport-form foldable, positioning it below the candy bar model. This is why the candy bar model gained the "Ultra" suffix to become the Z Fold 8 Ultra, while the new passport-form compact foldable claims the "Z Fold 8" name.

The message is clear: when Apple launches its foldable, Samsung can say, "You've finally made a foldable — great. We not only have the same form factor, but also a better Ultra version."

Media Consumption on the Compact Foldable

The Z Fold 8 inherits most of the Ultra's core features: titanium alloy flex hinge, minimal crease, new anti-reflective coating, silicon-infused battery. But it's a noticeably smaller phone — extremely light and thin at just 201 grams, comparable to a regular Galaxy S26 Plus, yet packing a cover screen, inner screen, and a 4500mAh battery.

The reviewer admitted to liking this model more and more over time, even drawing comparisons to the excellent hardware aspects of the Surface Duo. Of course, it clearly has less "substance" than the Ultra: smaller cover screen, smaller inner screen, smaller battery, and one fewer camera (only main and ultrawide).

The key lies in the positioning difference. The Ultra targets power users who need extensive multitasking and multiple apps side by side — the large inner screen is essentially two phones placed next to each other. The smaller Z Fold 8 leans more toward media consumption.

Cover Screen and Inner Screen Specs

The cover screen is 5.5 inches with a 10:16 ratio and narrow bezels all around; the inner screen is 7.6 inches (versus 8 inches on the Ultra), 4:3 ratio, with peak brightness reaching 5000 nits. The specs are equally impressive, but the smaller form factor makes it slightly less capable for multitasking while better suited for specific media scenarios.

Photography and Reading Experience

With the phone closed, everything in the camera viewfinder is more reachable — your thumb can easily reach all buttons, and the image fills more of the screen. When opened to review photos, since photos themselves are mostly in 4:3 ratio, they fill the screen perfectly. The reviewer also noted that such a lightweight device is excellent for e-book reading in either open or closed position. Widescreen video will still have black bars, but overall this is a comfortable device that fits the palm in both configurations.

Price Comparison of the Three Foldables

In terms of positioning, the Z Fold 8 sits between the fully-loaded Ultra and the clamshell Flip: fewer cameras (50MP main instead of 200MP), slightly less screen and battery, but the same core philosophy at a lower price.

However, this year's "lower price" doesn't feel particularly affordable, as prices across the board have increased. All three models start at 256GB:

• Z Flip 8: Starting at $1,200
• Z Fold 8 (compact passport form factor): Starting at $1,900
• Z Fold 8 Ultra: Starting at over $2,000

That's roughly $100 more than last year. The reviewer noted that many devices launching in the coming months will likely see price increases due to rising memory costs — especially the upcoming foldable iPhone.

This round of storage chip price increases is driven by multiple factors: Samsung, SK Hynix, and Micron — the three major memory manufacturers — aggressively cut production capacity in 2023 to clear inventory, tightening supply; explosive demand for HBM (High Bandwidth Memory) from AI servers has absorbed some DRAM production capacity; and the smartphone and PC replacement cycle recovery has boosted consumer-grade storage demand. For phone manufacturers, starting at 256GB storage means significantly higher per-unit flash memory costs compared to the 128GB era, and this cost pressure inevitably passes through to retail pricing. Foldable phones are particularly sensitive to storage price increases because their BOM (Bill of Materials) costs are already high — involving hinges, flexible displays, dual batteries, and other specialized components.

Conclusion: An Unexpected Daily Driver

The most surprising thing about this generation of Samsung foldables is the compact Z Fold 8. The reviewer initially wasn't optimistic about it, but after hands-on time genuinely felt it could serve as a daily driver.

From a product strategy perspective, Samsung's "Ultra + compact Fold" dual-flagship layout both defends its established multitasking large-screen market and preemptively positions against the passport form factor trend Apple may lead. The significant crease improvement, meaningful battery and charging upgrades also make this generation more than just routine "slow and steady" iteration. The foldable market is becoming increasingly exciting to watch.
