Samsung Galaxy S25 Plus VS Samsung Galaxy S25 Ultra 512GB

Both the Samsung Galaxy S25 Plus and the S25 Ultra share the same core durability credentials: both are rated IP68 waterproof and carry an identical French Repairability Index of 8.5, meaning neither holds an edge in protection against the elements or long-term serviceability. Their operating temperature range is also identical (0 °C to 35 °C), and neither offers a rugged build or a foldable form factor.

Where the two diverge is in physical footprint. The S25 Ultra is meaningfully larger across every dimension — 162.8 mm tall vs. 158.4 mm, 77.6 mm wide vs. 75.8 mm, and 8.2 mm thick vs. 7.3 mm — resulting in a volume of 103.6 cm³ compared to the S25 Plus's 87.6 cm³. In practice, this makes the Ultra noticeably bulkier and harder to pocket. The weight gap reinforces this: at 218 g, the Ultra is 28 g heavier than the S25 Plus's 190 g — a difference that becomes perceptible during extended one-handed use or all-day carry.

For users who prioritize a more pocketable, lighter device, the S25 Plus has a clear ergonomic edge in this category. The S25 Ultra's larger chassis is not a flaw per se — it accommodates a bigger display and battery — but purely from a design and handling standpoint, the S25 Plus is the more compact and comfortable option, with no trade-off in durability or repairability.

At their core, these two displays are nearly identical in technology and performance. Both deliver OLED/AMOLED panels with the same 1440 x 3120 px resolution, 120Hz refresh rate, 240Hz touch sampling rate, and a peak brightness of 2600 nits — ensuring equally fluid, vivid visuals in virtually all lighting conditions. HDR10 and HDR10+ support is shared across both, while neither supports Dolby Vision, so media compatibility is a wash.

The most meaningful display difference comes down to size versus pixel density. The S25 Ultra's 6.9″ screen offers more screen real estate — useful for multitasking, note-taking, or media consumption — but because the resolution is identical, its pixel density drops slightly to 498 ppi versus the S25 Plus's 513 ppi. In practice, both exceed the threshold where individual pixels are imperceptible to the human eye, so this difference is functionally invisible during normal use. The glass protection does diverge: the S25 Plus uses Gorilla Glass Victus 2, while the Ultra features Gorilla Armor 2, which is a more premium offering designed to reduce reflections and improve outdoor readability — a tangible real-world benefit that the raw specs table alone understates.

Overall, the display category is largely a tie on measurable performance metrics. However, the S25 Ultra holds a modest edge thanks to its larger screen and the superior anti-reflective properties of Gorilla Armor 2, making it the stronger choice for power users who consume a lot of content or work frequently in bright outdoor environments.

On paper, these two phones share an identical hardware foundation: the same Qualcomm Snapdragon 8 Elite chipset built on a 3 nm process, 12GB of RAM at 5300 MHz, 512GB of internal storage, and an Adreno 830 GPU — meaning day-to-day app launches, multitasking, and gaming performance should feel essentially the same in either hand.

The benchmark results, however, tell a nuanced story. The S25 Plus posts a significantly higher AnTuTu score of 3,050,000 versus the Ultra's 2,207,809 — a gap of roughly 38% that suggests the S25 Plus sustains higher peak throughput in that particular workload. Yet the picture reverses in Geekbench 6: the S25 Ultra scores higher in both single-core (3057 vs. 2721) and multi-core (9846 vs. 9435) tests, indicating stronger CPU execution efficiency under that benchmark's methodology. These contradictory results — same silicon, same TDP of 8.2W — point to differences in how each device manages thermal throttling and power delivery under sustained load, rather than any fundamental hardware distinction.

Given that the underlying specs are identical, declaring a clear winner here is not straightforward. The S25 Ultra edges ahead in CPU-focused Geekbench tasks, while the S25 Plus leads in the broader AnTuTu suite. For most users, neither gap will be perceptible in real-world use. This category is effectively a tie, with the choice coming down to which benchmark profile better reflects the user's specific workloads.

The camera systems are where these two phones diverge most dramatically. The S25 Plus fields a capable triple-lens setup with a 50 MP main, 12 MP ultrawide, and 10 MP telephoto, while the S25 Ultra goes considerably further with a quad-lens array headlined by a 200 MP main sensor, complemented by two 50 MP lenses and a 10 MP shooter. That 200 MP primary sensor is a generational leap in resolution terms — it captures a vastly greater amount of detail, giving users far more flexibility to crop aggressively in post without sacrificing image quality.

The telephoto gap is equally consequential. The S25 Plus tops out at 3x optical zoom with a focal range of 13–67 mm, whereas the S25 Ultra reaches 5x optical zoom and a maximum focal length of 111 mm — making it substantially more versatile for wildlife, sports, or any distant subject. The Ultra also adds laser autofocus, which the S25 Plus lacks; this improves focus acquisition speed and accuracy in low-light or fast-moving scenes. The wider maximum aperture on the Ultra's main lens (f/1.7 vs. f/1.8 on the S25 Plus) additionally allows slightly more light in, a small but meaningful advantage in dim conditions.

The front cameras and video capabilities are evenly matched — both shoot 8K at 30 fps, support HDR10 recording, and share the same 12 MP selfie sensor. But the rear camera story is one-sided: the S25 Ultra holds a clear and significant advantage in this category, offering more lenses, higher resolution, greater zoom range, and laser autofocus — making it the stronger choice for anyone who treats smartphone photography as a priority.

Running the same Android 15 foundation, these two phones share an extensive and nearly identical software feature set — from on-device machine learning and dynamic theming to split-screen multitasking, Picture-in-Picture, and offline voice recognition. For the vast majority of daily software interactions, users of either device will have an equivalent experience.

Three features, however, are exclusive to the S25 Ultra in this dataset. It supports cross-site tracking blocking, adding a layer of passive privacy protection when browsing that the S25 Plus does not offer. It also includes Wi-Fi password sharing, a convenience feature that lets users share network credentials with nearby contacts without manually reading out a password — a small but genuinely useful quality-of-life addition. Finally, the Ultra includes focus modes, which allow users to configure tailored digital wellness profiles that restrict notifications and app access during work, sleep, or personal time — something the S25 Plus lacks entirely.

None of these three differences are deal-breakers, but they are consistent, real-world advantages. The S25 Ultra holds a modest edge in this category — not because the S25 Plus is deficient in any major way, but because the Ultra's additional features cater to users who care about privacy controls and structured device management.

Charging infrastructure is identical across both devices: 45W wired fast charging, 15W wireless charging, and 4.5W reverse wireless charging are shared specifications, as is the absence of a bundled charger in the box. Neither has a removable battery, and both include an ultra power-saving mode for emergencies.

The only differentiator is raw battery capacity — the S25 Ultra carries a 5000 mAh cell versus the S25 Plus's 4900 mAh. A 100 mAh gap is, in practical terms, negligible; it translates to a difference of perhaps a few minutes of screen-on time under equivalent usage conditions. Worth noting is that the Ultra's larger display and heavier chassis mean it has more hardware to power, which partially offsets even that marginal capacity advantage.

This category is effectively a tie. The capacity difference is too small to influence a purchase decision, and every charging feature is mirrored exactly between the two phones. Battery life in real-world use will ultimately depend more on software optimization and display-on time than on this 100 mAh delta.

Audio is the rare category where there is genuinely nothing to separate these two phones — every single specification is identical. Both omit a 3.5 mm headphone jack, relying entirely on wireless or USB-C audio. Both feature stereo speakers and the same trio of wireless audio codecs: aptX, aptX HD, and LDAC. The inclusion of LDAC is particularly noteworthy, as it supports transmission rates up to 990 kbps — high enough to deliver near-lossless audio quality over Bluetooth when paired with a compatible headset, a meaningful benefit for audiophiles going wireless.

Neither phone supports aptX Adaptive or aptX Lossless, and neither includes a radio. Both also field 3 microphones, which enables beamforming and noise cancellation for cleaner call quality and voice recordings — again, a shared strength rather than a differentiator.

This category is an unambiguous tie. Users of either device will have an acoustically equivalent experience across speakers, wireless audio quality, and voice capture. Audio preference should play no role whatsoever in choosing between these two phones.

Connectivity credentials are virtually mirrored across both devices. Each supports 5G, Wi-Fi 7, Bluetooth 5.4, NFC, and USB 3.2 Type-C, with identical download and upload speed ceilings of 10,000 and 3,500 Mbps respectively. The dual SIM plus dual eSIM configuration, full sensor suite (gyroscope, accelerometer, barometer, compass), and ANT+ support are also shared — meaning neither phone holds any edge in how it connects to networks, peripherals, or accessories.

The one meaningful differentiator in this category is the included stylus on the S25 Ultra. For users who annotate documents, sketch, or take handwritten notes directly on their device, this is a significant functional advantage that the S25 Plus simply cannot replicate without an accessory purchase. It transforms the Ultra into a productivity tool in a way that connectivity specs alone cannot.

SAR values differ slightly between the two — the S25 Ultra has a lower Body SAR (US) of 0.64 W/kg versus the S25 Plus's 0.81 W/kg, while Head SAR values are comparable — but these figures are regulatory measurements rather than practical differentiators for most users. Overall, the S25 Ultra takes this category solely on the strength of its bundled stylus, which represents a tangible capability gap for productivity-focused users.

The miscellaneous feature set for these two phones is completely identical across every data point provided. Both include a video light, and neither features a sapphire glass display, a curved display, or an e-paper secondary screen. There is nothing in this group that separates the two devices in any meaningful way.

This category is an unambiguous tie, and should carry no weight in a purchase decision between the Samsung Galaxy S25 Plus and the S25 Ultra.
