Galaxy S25 Edge vs Z Fold 8 Ultra: Which Fits Your Needs?
If you want a slim, light phone that feels like a regular flagship, the Galaxy S25 Edge fits better; if you need a large foldable screen for multitasking and media, the Galaxy Z Fold 8 Ultra is the right choice. This article compares their design, displays, cameras, performance, and price to help you decide based on how you actually use your phone.
Background: Where These Phones Fit
Samsung’s Galaxy S series has always been the mainstream flagship line, and the “Edge� name returns with a focus on a thinner, lighter body and a curved-edge display. The Z Fold series, meanwhile, is Samsung’s premium foldable line, now in its “Ultra� iteration, which pushes the large inner screen and multitasking capabilities further. Both run the latest Android and One UI, but they target very different users: the Edge for those who want a conventional phone that’s easy to carry, the Fold for those who want a tablet-like experience in their pocket.
Design and Build: Thin vs. Transformable
The Galaxy S25 Edge is expected to be one of the thinnest flagships Samsung has made, with a rumored thickness around 6 mm and a weight under 180 grams. It keeps the familiar bar shape with a 6.6-inch display and an aluminum frame. The Z Fold 8 Ultra, by contrast, is a book-style foldable that opens to a large 8-inch inner screen, but it’s noticeably thicker and heavier—likely around 12 mm folded and over 240 grams. If you carry your phone in a tight pocket or prefer one-handed use, the Edge wins easily. If you’re willing to trade bulk for a bigger canvas, the Fold’s transformable design is unique.
Display and Multitasking
The S25 Edge likely has a 6.6-inch Dynamic AMOLED 2X display with a 120Hz refresh rate and a resolution around 2340×1080. It’s bright, sharp, and great for everyday use. The Z Fold 8 Ultra’s cover screen is similar (about 6.4 inches), but the inner screen is a 7.9- or 8-inch foldable display with a 120Hz refresh rate and a resolution around 2176×1812. That inner screen is where the Fold shines: you can run two apps side by side, use a floating window for a third, and even use the S Pen (sold separately) for notes or drawing. The Edge is a single-screen phone; the Fold is a multitasking powerhouse.
Camera Systems: Similar Hardware, Different Approach
Both phones are expected to share a similar camera setup: a 200MP main sensor, a 12MP ultrawide, and a 10MP telephoto with 3x optical zoom. The S25 Edge may have a slightly different arrangement to fit the thin body, but the core sensors are likely the same. The Z Fold 8 Ultra adds an under-display camera on the inner screen (a 4MP sensor) and a cover-screen camera (10MP), which are useful for video calls but not for serious photography. For most people, the Edge’s camera is easier to handle and produces identical quality to the Fold’s main cameras. The Fold’s advantage is the ability to use the main camera with the phone folded at an angle (thanks to the hinge) for hands-free shots or low-angle photography.
Performance and Battery
Both phones are expected to be powered by the Snapdragon 8 Gen 4 (or Exynos 2500, depending on region) with 12GB of RAM. In day-to-day use, you won’t notice a difference in speed. The battery, however, is a different story. The S25 Edge is rumored to have a 4,000mAh battery, which is modest for a flagship but adequate for a day of moderate use. The Z Fold 8 Ultra is likely to have a 4,400mAh battery, but the larger inner screen consumes more power, so battery life is roughly similar. Charging speeds are expected to be 45W for both, with wireless charging at 15W.
Price and Value
The Galaxy S25 Edge is expected to start around $1,300, similar to the standard S25 Ultra. The Z Fold 8 Ultra will likely cost significantly more, around $2,000. That’s a $700 difference. You’re paying a premium for the foldable display, the hinge mechanism, and the multitasking features. If you don’t need a tablet-sized screen, the Edge gives you most of the same camera and performance for much less. If you do want that big screen and use it daily, the Fold’s price might be justified.
Common Problems and Considerations
- Durability: Foldables are more fragile than bar phones. The inner screen can be scratched by debris, and the hinge can be damaged by drops. The Edge, being a traditional design, is more rugged.
- Weight and bulk: The Z Fold 8 Ultra is heavy and thick; it can be uncomfortable in a pocket or when using one-handed. The Edge is light and slim.
- Battery life: The Fold’s large screen drains battery faster; heavy users may need a midday top-up. The Edge’s smaller screen is more efficient.
- Software optimization: Not all apps are optimized for the Fold’s inner screen; some may appear stretched or have black bars. The Edge has no such issues.
How to Choose: A Simple Checklist
- Do you watch a lot of video or read documents on your phone? If yes, the Fold’s inner screen is a big advantage.
- Do you multitask (e.g., take notes while on a call)? The Fold’s split-screen is superior.
- Do you carry your phone in a pocket or use it one-handed? The Edge is far more comfortable.
- Is your budget flexible? If not, the Edge is the more sensible choice.
- Do you plan to use an S Pen? The Fold supports it; the Edge does not.
Frequently Asked Questions
Which phone has a better camera?
The main camera hardware is expected to be identical (200MP main, 12MP ultrawide, 10MP telephoto). The Edge’s camera is easier to use because it’s in a traditional bar design. The Fold’s under-display camera is lower quality, but you can use the main cameras for selfies by folding the phone and using the cover screen as a viewfinder.
Is the Z Fold 8 Ultra worth the extra money?
Only if you will actually use the inner screen for productivity or media. If you mostly use your phone for social media, calls, and quick photos, the Edge gives you the same core experience for less. The Fold’s value comes from its unique form factor, not its raw specs.
Does the S25 Edge have a curved screen?
Yes, the “Edge� name historically refers to a curved-edge display, and the S25 Edge is expected to have a subtle curve on both sides. This makes the phone look sleek and reduces bezels, but some users find it causes accidental touches.
Which phone is more durable?
The S25 Edge is more durable because it has a traditional design with no moving parts. The Z Fold 8 Ultra’s hinge and foldable screen are more vulnerable to drops and debris. Samsung has improved durability over the years, but it’s still not as rugged as a bar phone.
Can I use the S Pen with the S25 Edge?
No, the S25 Edge is not expected to support the S Pen. The Z Fold 8 Ultra does support the S Pen (sold separately), and it stores in a case or separately. If you need stylus input, the Fold is the only option.
Which phone has better battery life?
In real-world use, the S25 Edge likely has better battery life because it has a smaller screen and a similar battery capacity. The Fold’s larger screen consumes more power, so even with a bigger battery, it may not last as long. Both should get through a day with moderate use, but the Edge is safer for heavy users.
