With the summer Samsung Unpacked just a few months away, leaks have already painted a fairly clear picture. The Galaxy Z Fold 8 promises to be not just another update, but an answer to the question Samsung has long postponed: how to keep the crown in the foldable smartphone world when Apple is about to enter the ring.
This generation will bring us two book-style foldables from Samsung, a significantly larger battery, the possible return of stylus support, and an almost invisible crease. Let’s break it all down.
⚡ In a hurry? Here are the key takeaways:
- Battery: Grew for the first time in four generations—from 4,400 to ~5,000 mAh (+14%), and charging speed increased from 25W to 45W (+80%).
- Two versions: The classic Fold 8 (8″ inner screen) and the new Fold 8 Wide (7.6″, square format)—a direct competitor to the upcoming iPhone Fold.
- Crease: Will become almost invisible thanks to dual ultra-thin glass (dual-UTG) technology—reducing depth by at least 20%.
- Cameras: 200MP main camera (1/1.3″ sensor), and the ultrawide gets a 4x bump—from 12MP to 50MP.
- Cooling: A vapor chamber appears in the Fold for the first time, and the Snapdragon 8 Elite Gen 5 promises up to a 30–40% performance boost over its predecessor.
- Stylus support: The S Pen returns after skipping a generation—in a slimmer design compatible with the ultra-thin body.
- Price: Expected to remain at the Z Fold 7 level—$1,999, despite all the improvements.

Fold 8 vs. Fold 7: What Changed on Paper
Before diving into the details, here is a visual comparison of the two generations—you can immediately see where Samsung stepped up and where things stayed the same:
As you can see, with practically unchanged dimensions and price, Samsung managed to improve almost every aspect. Let’s look at each of the innovations in more detail.
Battery and Charging: Finally a Breakthrough
If we were asked to name the main weakness of the Fold series in recent years, the answer would be simple—battery life. From the Galaxy Z Fold 3 (2021) to the Galaxy Z Fold 7 (2025), battery capacity remained unchanged at 4,400 mAh. Four consecutive generations!
And now, Samsung has finally decided to upgrade. According to Android Headlines, the Z Fold 8 will feature a dual-cell battery with a total capacity of around 4,845 mAh (2,369 + 2,485 mAh), which Samsung will likely market as a 5,000 mAh typical capacity. That’s an increase of about 14%.
It might not seem like a revolution, but there’s a crucial nuance here.
Optimization can mean more than capacity. The Galaxy S26 Ultra clearly demonstrated what the new chipset is capable of when paired with updated One UI software: with the same 5,000 mAh battery, it runs for over 16 hours in GSMArena tests—an hour and a half longer than the S25 Ultra with an identical battery.

In other words, the Fold 8 will benefit from two factors at once: an increased capacity and a more efficient chip. The result could be very impressive.
No less noticeable is the leap in charging speed. Samsung is moving from 25W straight to 45W—an 80% increase. Both versions of the Fold 8 have already passed 3C certification in China, supporting up to 15V × 3A. For those accustomed to plugging their smartphone into an outlet for 10–15 minutes before heading out, the difference will be noticeable.
Silicon-carbon batteries? Another curious question is exactly how Samsung managed to fit 600 mAh more energy, add a vapor chamber for cooling, and still make the device 15 grams lighter?
Perhaps these are the first fruits of silicon-carbon battery technology, something Samsung SDI has been working on for years. Or maybe the engineers just brilliantly optimized the internal layout. Either way, the result is impressive.

An Almost Invisible Crease
The screen crease is the eternal Achilles’ heel of all book-style foldables. With each generation, it became less noticeable, but it never completely disappeared for any manufacturer.
In the Z Fold 8, Samsung will use dual ultra-thin glass (dual-UTG) technology combined with a laser-drilled metal support plate. The company previously demonstrated this panel at CES 2026.
According to preliminary data, the depth of the crease will be reduced by at least 20% compared to the Z Fold 7, and in the wide version of the Fold, the result may be even better. It is highly likely that with this generation, the crease will finally cease to be a reason not to buy a foldable.

Why does this really matter? It’s not just about aesthetics. The crease gets in the way when sliding a finger across the center of the screen—while reading, drawing, or using a stylus. If Samsung manages to minimize it, the user experience will feel much closer to that of a regular tablet.
Cameras: A Major Ultrawide Upgrade, But Questions Remain
The main camera of the Z Fold 8 will remain 200-megapixel with a 1/1.3″ sensor—the same one that debuted in the Z Fold 7. According to GSMArena, the configuration will look like this:
- Main: 200 MP, 1/1.3″ sensor, presumably f/1.7 (or possibly f/1.4, similar to the S26 Ultra)
- Ultrawide: 50 MP — ✔ replacing the old 12 MP
- Telephoto: 10 MP, 3x optical zoom — ✖ unchanged
The most notable upgrade is the ultrawide module. Moving from 12 to 50 MP is not just about more pixels. A larger sensor captures more light, which is critical for indoor group photos and twilight landscapes. The fourfold resolution increase will also allow for much more confident cropping—for example, isolating a single building from a city panorama without a catastrophic loss of detail.
Cameras on the current Galaxy Z Fold 7 model
On the other hand, the 200 MP main camera is primarily a reserve for cropping and digital zoom. Even if you crop the frame in half, you still have a 50 MP image—more than enough for any screen or print.
An f/1.4 aperture—dream or reality? If Samsung brings the f/1.4 lens from the Galaxy S26 Ultra to the Fold 8, the impact will be significant. Compared to the f/1.7 lens on the Z Fold 7, an f/1.4 lens lets in approximately 47% more light. In low-light conditions—which includes every evening and night shot—the difference can literally be between a “blurry mess” and a sharp photo.
However, for now, this is just our assumption, not confirmed insider info.
Telephoto—the weak link. There were rumors of a telephoto lens upgrade, but recent leaks point to the same 10-megapixel module with 3x zoom. For a foldable device, this is somewhat understandable: space inside the chassis is limited, and periscope optics require room. But compared to the 5x zoom of the Galaxy S26 Ultra and competitors’ flagships, it looks modest.

Processor and Cooling: Not Just Faster, but Fundamentally Different
The Z Fold 8 will get the Snapdragon 8 Elite Gen 5 for Galaxy—the same flagship chip found in the Galaxy S26 Ultra.
Qualcomm’s flagship processor lineup has come a long way in recent years, confusing users with its naming conventions along the way:
- 2024: Snapdragon 8 Gen 3 (4nm process)
- 2025: Snapdragon 8 Elite (3nm)
- 2026: Snapdragon 8 Elite Gen 5 (3nm, refined)
According to early estimates, performance improvements will be around 30–40% compared to the chip in the Z Fold 7. For those upgrading from the Z Fold 6 (Snapdragon 8 Gen 3), the difference will be even more noticeable—effectively spanning two full generations.
The “for Galaxy” version, as a reminder, features slightly overclocked frequencies.
But what’s much more important is exactly how this processor will operate inside a foldable chassis. And here lies perhaps one of the most underrated innovations.
Vapor chamber—a first for the Fold series. Until now, Samsung’s foldables relied on graphite pads for heat dissipation. This worked, but under prolonged load—heavy gaming, video recording, AI processing—the processor was forced to throttle frequencies to prevent overheating.

A vapor chamber is a thin, sealed plate with liquid inside that vaporizes in the hot zone and condenses in the cold zone, distributing heat evenly. This cooling system has been standard in standard Samsung flagships for years but is appearing in a foldable device for the first time.
What this means in practice:
- Stable performance: The processor runs at peak frequencies longer without throttling.
- Comfortable device temperature: Heat is distributed over a larger area rather than concentrated in one spot.
- Better energy efficiency: An overheating chip consumes more power, so effective cooling indirectly extends battery life.
Combined with One UI 9 optimizations and a larger battery, it creates a “perfect storm”—all three factors are working together in the right direction.
The S Pen Returns
The Galaxy Z Fold 7 became the first Fold without stylus support—Samsung sacrificed it for a record-thin body. The decision proved controversial: many users chose the Fold precisely for the ability to write and draw on the large foldable screen.

In the Z Fold 8, according to numerous rumors, the S Pen will return—and in a slimmer design that won’t require thickening the device. Whether the stylus will be built into the body or sold separately again remains unknown. But even separately is better than nothing at all.
The return of the stylus is especially logical alongside the nearly invisible crease. Drawing and writing on an 8-inch screen without a “bump” in the middle is a completely different experience than before.
Dimensions and Durability: Lighter but Stronger
According to SamMobile leaks, the dimensions of the Z Fold 8 are nearly identical to its predecessor:
- Unfolded: 158.4 × 143.2 × 4.5 mm
- Folded: 158.4 × 72.8 × 9 mm
Technically, this is 0.1–0.3 mm thicker than the Z Fold 7, but real-world measurements of the previous model showed roughly the same numbers, so the actual difference is likely zero.

However, the weight is a pleasant surprise. According to the Korean publication Maeil Business, the Z Fold 8 will shed some weight, dropping to around 200 grams. Let’s recall the evolution:
- Z Fold 6 (2024): 239 g
- Z Fold 7 (2025): 215 g
- Z Fold 8 (2026): ~200 g
In two years, Samsung has shaved off nearly 40 grams—about the weight of a small chocolate bar. For a device you carry in your pocket, every gram counts.
Certain insiders also mention increased chassis durability. There aren’t many details yet, but in the context of foldable devices, where the hinge and body experience constant stress, any structural reinforcement is a welcome addition.
Fold 8 Wide: Why Does Samsung Need a Second Foldable?
The short answer is: the iPhone Fold.
Apple is preparing its first foldable smartphone, expected to be announced in the fall of 2026, and Samsung wants to meet the competitor fully armed. Therefore, alongside the classic Fold 8, the company will release a model codenamed H8 (SM-F971U)—the Galaxy Z Fold 8 Wide.
This is what the Galaxy Fold 8 Wide might look like
The core idea: while the regular Fold is tall and narrow, the Wide is short and wide. The cover screen has an 18:9 aspect ratio, and when unfolded, it turns into an almost square 18:18 (~1:1) display.
This is a fundamentally different format. The classic Fold in its unfolded state resembles a stretched tablet—great for reading and document work. The Wide Fold is closer to the iPad mini format: a square screen that is equally good for web browsing, videos, photos, and multitasking.
How the Wide differs from the regular Fold 8:
- Inner screen: 7.6″ (vs. 8.0″ on the regular Fold 8)
- Cover screen: 5.4″ (vs. 6.5″)
- Cameras: Only two—no telephoto lens
- Dimensions (unfolded): 123.9 × 161.4 × 4.9 mm—noticeably wider, but shorter
- Dimensions (folded): 123.9 × 82.2 × 9.8 mm
- Battery and charging: Same as the regular Fold 8—~5,000 mAh, 45W
According to Sammy Fans, the production volume of the Wide version will be around 1 million units—a third of the standard Fold 8’s volume (3.5 million). Samsung is clearly testing demand but is taking the venture seriously.
The expected price is around $2,000, roughly on par with the standard Fold 8. A slight discount is possible due to the lack of a telephoto lens and more compact screens. Also, according to rumors, the Wide version may receive S Pen support—a stylus would be particularly fitting on a square screen.

iPhone Fold on the Horizon: What to Expect from Apple?
Since Samsung is creating an entire model specifically to compete with the foldable iPhone (link to our article), it’s worth briefly describing what is known about the Apple rival.
According to MacRumors and analyst Ming-Chi Kuo, the foldable iPhone will feature an iPad mini-sized OLED screen (~7.8″ unfolded), a titanium hinge, and—what’s particularly intriguing—a completely invisible crease. Apple reportedly eliminated it “regardless of cost” by developing an entirely new material.
Other expected features:
- Cameras: Dual 48 MP module (main + ultrawide), no telephoto
- Biometrics: Touch ID instead of Face ID—to maintain a thin profile
- Battery: ~5,500 mAh
- Price: From $2,000, with some estimates reaching up to $2,500
The announcement of the iPhone Fold is expected in September 2026, but actual sales might only begin in November or December. This gives Samsung a strategic 4–5 month advantage if the Z Fold 8 is released in July.

However, a time advantage and a product advantage are not the same thing. Apple knows how to enter a market second and still set the standards.
What Might Fold 8 Inherit from the Galaxy S26 Ultra?
The Z Fold 8 traditionally inherits some new features from Samsung’s spring flagship. In 2026, the Galaxy S26 Ultra introduced several interesting functions that we logically expect to see in the foldable smartphone as well.
Bluetooth 6.0. The Galaxy S26 Ultra already received this version, upgrading from Bluetooth 5.4 in its predecessor. The new standard is primarily notable for its precise distance measurement down to the centimeter—useful for finding devices, smart home integration, and future AR applications. Wireless connection power efficiency has also been improved, which is crucial for wearables like earbuds and smartwatches.
Privacy Display. One of the most discussed new features of the Galaxy S26 Ultra is hardware-level screen protection against snooping. The technology works at the display panel level: when activated, the screen is clearly visible only when looking directly at it. Anyone looking from an angle will only see a darkened image.

In the settings, you can protect the entire screen or just specific elements—like notifications and banking apps. For a foldable device that opens up into an 8-inch “tablet” on public transport, such a feature would be especially handy.
We should note: the inclusion of Bluetooth 6.0 in the Fold 8 is highly probable (Samsung usually unifies such modules), but the Privacy Display is our educated guess based on the logic of the lineup’s evolution.
When to Expect It and How Much Will It Cost?
The announcement of the Galaxy Z Fold 8, as per tradition, is expected at the summer Samsung Unpacked event. In recent years, it has taken place in mid-July.
According to data from Ice Universe, Samsung has decided to keep the lineup’s pricing without any increases. This means the starting price of the Z Fold 8 will remain at the same $1,999 as the Z Fold 7.
Considering the sheer volume of improvements—a larger battery, fast charging, a vapor chamber, the potential return of the stylus, and better cameras—maintaining the price is a strong move, especially against the backdrop of the expected $2,000–$2,500 price tag for the iPhone Fold.
Galaxy Z Fold 7 and Z Flip 7
In addition to the two Fold models, Samsung will traditionally showcase the updated Galaxy Z Flip 8, new Galaxy Watches, and—according to rumors—possibly the first teaser for Samsung smart glasses at the summer Unpacked. If Apple plans to announce its smart glasses before the end of the year, Samsung will certainly try to beat its rival, at least with an announcement.
Production volumes. According to an insider tip from Ice Universe, Samsung plans to produce about 3.5 million units of the Fold 8 and 2.5–3 million units of the Flip 8. The Fold 8 Wide will see about 1 million units produced. The numbers are modest by standard flagship metrics, but foldables remain a niche, albeit a growing segment.
Software and Update Support
The Z Fold 8 will run on One UI 9—the next version of Samsung’s custom skin. The update support window will be up to 7 years, just like its predecessor.
Seven years of updates for a foldable smartphone is a serious statement. Essentially, by purchasing the device in 2026, you will receive fresh Android versions and security patches until at least 2033.
Pros and Cons of the Galaxy Z Fold 8
Based on all leaks and rumors, the picture looks like this:
Pros:
- Battery has finally increased—for the first time in four generations
- 45W charging instead of 25W (+80%)
- Vapor chamber for stable performance under load
- Practically invisible crease (dual-UTG)
- 50 MP ultrawide camera instead of 12 MP
- Return of S Pen support
- Weight reduced to ~200 g (15 g less than Fold 7)
- Price hasn’t increased—$1,999
- 7 years of updates
- Introduction of the Wide version—more choices
Cons:
- Telephoto lens likely remains the same—10 MP, 3x
- Price is still $1,999—foldable flagships aren’t getting cheaper
- Design remains almost visually identical
- Wireless charging will likely stay at previous levels
- Wide version lacks a telephoto lens
- Cover screen hasn’t grown compared to Fold 7
Is the Z Fold 8 Worth Waiting For?
If you look at the evolution of the Fold lineup over the last few years, it becomes clear: Samsung has finally stopped “holding back” on upgrades. The Z Fold 6 was a careful, but unexciting step forward. The Z Fold 7 impressed with a thin body and a better camera, but disappointed with the lack of an S Pen and the same old battery.
The Z Fold 8 looks like an attempt to bring together the best of everything: the thin body of the Fold 7, the return of the stylus, increased battery life, fast charging, proper cooling, and an almost invisible crease. And all this—while keeping the price the same.

**For Z Fold 7 owners,** the upgrade might not seem as obvious: the design and screens are virtually identical, and the main camera is the same. The main arguments “for” are the battery, charging, and the return of the stylus.
**For owners of the Z Fold 6 and older,** the picture is completely different. In two years, the series has come a incredibly long way: the body is 26% thinner, 39 grams lighter, the camera grew from 50 to 200 MP, and the battery finally got a boost. If you’ve been eyeing an upgrade for a while, the Z Fold 8 might be the perfect moment.
And for those considering a fundamentally new format, there’s the Fold 8 Wide—a door into the world of “square” foldable smartphones, where Samsung aims to meet Apple before it even gets a chance to enter.
