Samsung Galaxy S25 VS Samsung Galaxy Z Fold 7

The most fundamental difference here is form factor: the Galaxy S25 is a traditional candybar slab, while the Galaxy Z Fold 7 is a foldable device. When unfolded, the Z Fold 7 stretches to a 143.2 mm width — nearly double the S25's 70.5 mm — making it closer to a compact tablet. That extra footprint comes at a cost: the Z Fold 7 weighs 215 g versus the S25's notably lighter 162 g. In practice, 53 grams is a meaningful difference during one-handed use or extended holding sessions, and the Z Fold 7's bulk when folded will be more noticeable in a pocket.

Where the Z Fold 7 surprises is in thinness. At just 4.2 mm thick (unfolded), it actually undercuts the S25's 7.2 mm profile — an engineering feat given its hinge mechanism. However, keep in mind that when closed, a foldable's thickness roughly doubles, so real-world pocketability is more nuanced than this single number suggests. On water resistance, the S25 holds a slight but tangible edge with an IP68 rating versus the Z Fold 7's IP67 — meaning the S25 can handle deeper submersion, which matters if you're frequently near water.

Overall, neither phone is objectively ″better″ in design — they serve different needs. The Galaxy S25 has a clear advantage in ergonomics and portability, being lighter and conventionally sized for one-handed use. The Galaxy Z Fold 7 trades that comfort for a transformative large-screen experience. The S25 also edges ahead on water resistance. If compactness and ease of handling are priorities, the S25 wins; if you want a device that doubles as a tablet, the Z Fold 7's unique form factor justifies its added weight and size.

Screen size is the headline story here. The Z Fold 7's inner display stretches to 8″ — a full 1.8 inches larger than the S25's 6.2″ panel — which translates to significantly more usable area for multitasking, media consumption, and reading. The trade-off shows up in pixel density: the S25's smaller canvas packed to 416 ppi renders text and fine detail with a sharper edge than the Z Fold 7's 368 ppi. That gap is noticeable under close inspection, though both sit above the threshold where most users would call the difference critical in everyday use.

Where the two phones converge is striking. Both use OLED/AMOLED panels with identical 120Hz refresh rates and a peak brightness of 2600 nits — ensuring equally smooth scrolling and strong outdoor legibility. HDR10+ support and Always-On Display are present on both, so the viewing experience quality is well-matched beyond raw size. One meaningful divergence, however, is glass protection: the S25 is confirmed to use Gorilla Glass Victus 2 on its display, while the Z Fold 7's data indicates no branded damage-resistant glass on the main screen — a real-world durability concern given that inner foldable panels are inherently more delicate.

On balance, the Galaxy S25 holds an edge in display sharpness and screen durability. The Z Fold 7 counters with a dramatically larger canvas and a secondary cover screen, making it the superior choice for productivity and immersive media — but users should be aware that its main display carries greater fragility risk. The right pick depends entirely on whether you prioritize screen real estate or a more durable, razor-sharp panel.

Both phones are built on the same foundation — the Qualcomm Snapdragon 8 Elite on a 3 nm process with the Adreno 830 GPU — so the real story here is how each device tunes that shared silicon. The S25 runs its prime CPU cores at 4.47 GHz versus the Z Fold 7's 4.32 GHz, and its GPU is clocked higher at 1200 MHz compared to 1100 MHz. Those differences compound in the AnTuTu benchmark, where the S25 pulls ahead with 3,050,000 versus the Z Fold 7's 2,771,639 — a roughly 10% gap that likely reflects the thermal constraints of fitting the same chip into a thinner, more complex foldable chassis.

Geekbench 6 tells a more nuanced story: single-core and multi-core scores are essentially identical between the two, meaning sustained real-world CPU tasks — app launches, browsing, everyday productivity — will feel indistinguishable. The Z Fold 7 compensates for its slightly lower peak performance with 16 GB of RAM versus the S25's 12 GB, a meaningful advantage for heavy multitasking, especially given its tablet-sized display encourages running multiple apps simultaneously. Storage also favors the Z Fold 7 significantly, with 1 TB compared to the S25's 512 GB.

This category ends in a split verdict. The Galaxy S25 has a clear edge in raw peak performance — particularly GPU throughput, which matters for gaming and graphics-intensive workloads. But the Z Fold 7 is the more capable multitasking machine thanks to its extra RAM, and its 1 TB storage suits power users who never want to manage space. Neither phone will feel slow; the choice comes down to whether you prioritize peak speed or headroom for demanding parallel workflows.

The main camera gap is impossible to ignore: the Z Fold 7 leads with a 200 MP primary sensor versus the S25's 50 MP, and pairs it with a slightly wider aperture of f/1.7 compared to f/1.8 on the S25. More megapixels mean greater flexibility to crop aggressively without losing detail — a genuine advantage for photography enthusiasts. Both phones share identical 3x optical zoom and ultrawide configurations, and both shoot up to 4K/30fps video with OIS, so the gap narrows considerably outside of that primary sensor. The Z Fold 7 also adds laser autofocus and native 360° panorama support, features absent on the S25, further reinforcing its position as the more capable imaging platform on paper.

The front camera picture is more nuanced. The S25 uses a single 12 MP selfie shooter, while the Z Fold 7 carries two front cameras: a standard 10 MP sensor plus an under-display camera — the latter being the cover screen camera that keeps the large inner screen entirely uninterrupted. The under-display solution is a unique structural advantage of the foldable form. However, the S25's front camera aperture is f/2.2, while the Z Fold 7's wider front camera opens to f/1.8, meaning the Fold captures more light for selfies in low-light conditions.

Across almost every camera dimension, the Galaxy Z Fold 7 holds a clear edge — higher-resolution main sensor, wider aperture, laser autofocus, panorama shooting, and a more versatile front camera setup. The Galaxy S25 remains a very capable shooter, but the data leaves no ambiguity: the Z Fold 7 is the stronger camera system of the two.

This is a rare case where the data tells a completely flat story: both the Galaxy S25 and the Galaxy Z Fold 7 run Android 15 and share an identical feature set across every single specification in this group. From privacy controls — location, camera, microphone, and app tracking — to productivity features like split screen, Picture-in-Picture, and PC mode, there is no divergence whatsoever between the two devices at the OS level.

The shared capabilities are substantial and worth noting for context. Both phones support on-device machine learning, offline voice recognition, dynamic theming, and multi-user functionality — a well-rounded software platform by any measure. Neither device gets direct OS updates from Google, meaning both rely on Samsung's update pipeline, and neither supports Wi-Fi password sharing or focus modes, applying the same limitations equally.

The verdict here is a complete tie. Not a close call — a perfect match. Any software experience differences between these two phones will come from Samsung's foldable-specific UI optimizations built on top of Android, which fall outside the scope of the provided specs. Based strictly on the data, the operating system category offers zero differentiation and should not factor into a purchase decision between these two devices.

Battery capacity is the only differentiator in this group, and it is a modest one. The Z Fold 7 packs a 4400 mAh cell against the S25's 4000 mAh — a 10% advantage on paper. In isolation, more capacity generally means longer time between charges, but the real-world gap here is complicated by context: the Z Fold 7 also drives a much larger 8″ display, which draws considerably more power. The net result is that the larger battery may simply be compensating for greater screen demand rather than delivering meaningfully longer endurance.

Every other battery specification is a mirror image. Both phones charge at 25W wired, support 15W wireless charging, and offer 4.5W reverse wireless charging — useful for topping up earbuds or a smartwatch. Neither has a removable battery, which is standard for flagship devices of this class.

On the specs alone, the Z Fold 7 holds a narrow technical edge in capacity, but the advantage is tempered by its power-hungry larger display. The Galaxy S25 has a smaller battery but also a far less demanding screen to feed. For charging speed and wireless capability, this is a complete tie. Users prioritizing all-day battery life should weigh the Z Fold 7's larger cell against its heavier display workload rather than treating the raw mAh difference as a straightforward win.

Audio is nearly identical across both devices, with one exception worth calling out. Both phones drop the 3.5mm headphone jack — standard practice for flagship Android devices — and both deliver stereo speakers alongside support for aptX and LDAC wireless audio codecs. LDAC in particular is the high-fidelity option, capable of transmitting audio at up to three times the bitrate of standard Bluetooth, making it the relevant codec for audiophiles using compatible wireless headphones.

The single differentiator is the Z Fold 7's addition of aptX HD support, which the S25 lacks. aptX HD is Qualcomm's high-resolution wireless audio codec, designed to transmit 24-bit audio over Bluetooth with lower latency than standard aptX. In practice, its real-world benefit over LDAC — which both devices share — is marginal and highly dependent on whether the user owns aptX HD-compatible headphones. For most listeners, the overlap with LDAC makes this a secondary consideration rather than a decisive one.

The Galaxy Z Fold 7 holds a narrow technical edge here by virtue of supporting a broader codec range, but in practice this advantage will only matter to users with specifically aptX HD-compatible audio gear. For everyone else, the two phones are effectively tied on audio — same speaker setup, same high-fidelity wireless codec support, and the same absence of a headphone jack.

Connectivity is broadly matched between these two devices, with both supporting 5G, Wi-Fi 7, Bluetooth 5.4, NFC, and USB 3.2 Type-C. Peak download and upload speeds are identical at 10,000 Mbits/s and 3,500 Mbits/s respectively, and the full sensor suite — gyroscope, accelerometer, barometer, compass, and GPS with Galileo — is present on both. For the vast majority of connectivity use cases, these phones are effectively equivalent.

Two differences are worth flagging. First, SIM configuration: the S25 supports 2 physical SIMs plus 2 eSIMs, while the Z Fold 7 offers only 1 physical SIM and 1 eSIM. For users who regularly juggle multiple lines — frequent travelers or dual work/personal setups — the S25's greater SIM flexibility is a practical advantage. Second, the S25 supports ANT+, a low-power wireless protocol widely used to connect fitness accessories like heart rate straps, cycling sensors, and GPS devices. The Z Fold 7 omits this, which is a niche but real limitation for dedicated fitness and outdoor activity users.

The Galaxy S25 earns a narrow edge in this category. Its dual-SIM dual-eSIM configuration and ANT+ support address specific but meaningful use cases that the Z Fold 7 simply does not cover. For users who have no need for multiple SIM lines or ANT+ accessories, the two phones are otherwise functionally identical in connectivity and features.

The Miscellaneous group offers no differentiation whatsoever between these two devices. All three specifications — video light, sapphire glass display, and e-paper display — return identical values for both the Galaxy S25 and the Galaxy Z Fold 7. This is a complete tie by the data, and no meaningful comparison can be drawn from it.

The shared absence of a sapphire glass display is the one note worth contextualizing: sapphire glass, while extremely scratch-resistant, is rare in consumer smartphones due to its high production cost and brittleness under impact. Neither phone pursues that premium but niche feature, which is consistent with the broader flagship Android market.

Based strictly on the provided specs, this category should carry no weight in a purchase decision. There is nothing here that distinguishes one device from the other.
