Samsung Galaxy S25 VS Xiaomi Poco F7 Ultra

Both the Samsung Galaxy S25 and the Poco F7 Ultra share the same IP68 waterproof rating, meaning both can withstand submersion in fresh water up to 1.5 meters for 30 minutes. Neither adopts a rugged build or a foldable form factor, so on those fronts they are evenly matched.

Where the two phones diverge significantly is in their physical footprint. The Galaxy S25 is notably more compact, measuring 146.9 × 70.5 × 7.2 mm and weighing just 162 g, while the Poco F7 Ultra stretches to 160.3 × 75 × 8.4 mm at 212 g. That 50-gram weight difference is meaningful in daily use — the S25 will feel considerably lighter during long sessions and one-handed operation, while the F7 Ultra's extra bulk is something you will notice in a pocket or during extended calls. The volume gap reinforces this: the S25 displaces roughly 74.6 cm³ versus the F7 Ultra's 101 cm³, making the Samsung nearly 35% more compact by volume.

The Samsung Galaxy S25 has a clear advantage in this category for users who prioritize a slim, lightweight, and pocketable device. The Poco F7 Ultra's larger chassis may accommodate a bigger battery or more elaborate cooling, but strictly from a design and ergonomics perspective, the S25 is the more refined and comfortable form factor.

On paper, the Poco F7 Ultra holds a substantial edge in raw display fidelity. Its 1440 × 3200 px resolution across a 6.67″ panel yields a pixel density of 526 ppi, compared to the Galaxy S25's 1080 × 2340 px at 416 ppi on a 6.2″ screen. The difference is perceptible up close — text appears crisper and fine detail in photos and video is more faithfully rendered on the F7 Ultra, making it the stronger choice for media consumption and content creators who scrutinize sharpness.

The brightness story flips the advantage, however. The Galaxy S25 reaches a peak typical brightness of 2600 nits versus the F7 Ultra's 1800 nits — a meaningful gap in outdoor legibility under direct sunlight. The S25 also picks up an exclusive with Dolby Vision support absent on the F7 Ultra, broadening its compatibility with premium streaming content. The F7 Ultra counters with a 480Hz touch sampling rate versus the S25's 240Hz, which translates to more responsive input detection — a genuine advantage in competitive gaming scenarios. Both panels share a 120Hz refresh rate, HDR10+, and Always-On Display support.

This group does not produce a single overall winner — it depends on priority. The Poco F7 Ultra wins on sharpness and touch responsiveness, making it the better pick for gamers and detail-oriented viewers. The Samsung Galaxy S25 wins on peak brightness and Dolby Vision compatibility, giving it the edge for outdoor use and premium streaming. Neither is a compromise; they simply target different display priorities.

At first glance, both phones appear nearly identical in this category — and for good reason. They share the same Qualcomm Snapdragon 8 Elite chip built on a 3 nm process, the same Adreno 830 GPU, identical memory bandwidth, and the same TDP. Yet the Samsung Galaxy S25 consistently outperforms the Poco F7 Ultra across every benchmark recorded. The S25 scores 3,050,000 on AnTuTu versus the F7 Ultra's 2,580,490, leads in Geekbench 6 single-core (3175 vs 2970) and multi-core (10,050 vs 8,887), and pulls ahead in the 3DMark GPU test as well. The reason traces back to clock speeds: Samsung's implementation runs its prime cores at 4.47 GHz compared to Xiaomi's 4.32 GHz, and the GPU is clocked at 1200 MHz versus 1100 MHz — a more aggressive silicon tuning that extracts meaningfully more headroom from the same hardware.

The Poco F7 Ultra does answer with 16 GB of RAM against the S25's 12 GB, which offers a practical advantage in extreme multitasking — keeping more apps resident in memory simultaneously and reducing reload times when switching between heavy applications. Both phones cap out at the same 512 GB storage configuration in this comparison, so that is a non-factor.

The Samsung Galaxy S25 holds the performance edge here, delivering faster real-world CPU and GPU throughput thanks to its higher-clocked Snapdragon 8 Elite variant. The Poco F7 Ultra's extra RAM cushion is useful but does not overcome the S25's consistent lead across every benchmark metric provided.

The rear camera systems take noticeably different approaches. The Poco F7 Ultra goes wide with high-resolution sensors across the board — 50 & 50 & 32 MP — and pairs them with wider maximum apertures (f/1.6, f/2.0, f/2.2), meaning each lens gathers more light than its Galaxy S25 counterpart. The Galaxy S25 opts for a more varied resolution spread of 50 & 12 & 10 MP with slightly narrower apertures (f/1.8, f/2.2, f/2.4), but compensates with a longer optical zoom reach of 3x versus the F7 Ultra's 2.5x, and a wider focal range — topping out at 67 mm equivalent versus 60 mm. For telephoto shooting and versatility at distance, the S25 edges ahead.

Several feature-level differentiators tilt further in the S25's favor. It supports RAW capture, manual shutter speed, 8K video at 30 fps, and HDR10 video recording — none of which are available on the F7 Ultra. The absence of RAW shooting on the F7 Ultra is a meaningful limitation for photography enthusiasts who process images in post. The S25 also carries a BSI sensor on its main camera, which is engineered for improved low-light performance. The F7 Ultra's higher front camera resolution (32 MP vs 12 MP) is its clearest win for selfie-focused users.

The Samsung Galaxy S25 holds the broader camera advantage in this group, offering greater telephoto reach, RAW support, more manual controls, and superior video feature depth. The Poco F7 Ultra's wider apertures and higher secondary sensor resolutions are genuine strengths, particularly for still photography in good light, but the S25's overall camera versatility gives it the edge for users who demand more from their imaging system.

Rarely does a specification group produce such a near-perfect draw, but the operating system category is essentially that. Both phones run Android 15, and across the entire feature list — privacy controls, dark mode, dynamic theming, split-screen, Picture-in-Picture, on-device machine learning, offline voice recognition, and more — they are spec-for-spec identical. Neither receives direct OS updates from Google, and both share the same gaps, such as no cross-site tracking blocking and no focus modes.

The sole differentiator in this entire group is that the Samsung Galaxy S25 supports being used as a PC, while the Poco F7 Ultra does not. This refers to desktop mode functionality — the ability to connect the phone to a monitor and use it as a makeshift computer with a windowed interface. For users who travel light and want to occasionally work from a larger screen without carrying a laptop, this is a genuinely useful capability. For everyone else, it is unlikely to factor into a purchase decision.

This group is effectively a tie, with the Galaxy S25 claiming a narrow, situational edge via its desktop PC mode. Outside of that single feature, both phones offer an identical Android 15 software experience based strictly on the provided data.

The battery category is one of the Poco F7 Ultra's strongest arguments. Its 5300 mAh cell is 32% larger than the Galaxy S25's 4000 mAh pack — a substantial gap that, all else being equal, translates directly into meaningfully longer time between charges. Combine that with the F7 Ultra's larger and more power-hungry display, and the raw capacity advantage becomes even more relevant for heavy users who routinely push through a full day.

Charging speed tells an equally one-sided story. The F7 Ultra's 120W wired charging dwarfs the S25's 25W, meaning the Xiaomi can go from near-empty to full in a fraction of the time. The same gap carries over to wireless: 50W versus 15W. The F7 Ultra also ships with a charger in the box, while Samsung requires a separate purchase — a practical cost consideration. The Galaxy S25 counters with reverse wireless charging, allowing it to top up accessories like earbuds or a smartwatch, a feature the F7 Ultra lacks entirely.

The Poco F7 Ultra wins this category decisively on the two metrics that matter most to most users: raw endurance and replenishment speed. The Galaxy S25's reverse wireless charging is a convenient perk but does not offset the F7 Ultra's commanding leads in battery capacity and charging wattage.

Audio is another category where the two phones are almost indistinguishable. Both drop the 3.5mm headphone jack, offer stereo speakers, and support the same core suite of high-resolution Bluetooth codecs: aptX, LDAC, aptX Adaptive, and aptX Lossless. For wireless audio enthusiasts, this means both phones are well-equipped to stream near-lossless audio to compatible headphones, with aptX Lossless in particular capable of delivering CD-quality audio over Bluetooth when paired with a supported device.

The single differentiator is the Poco F7 Ultra's additional support for aptX HD. This codec sits in the high-resolution tier, offering 24-bit audio streaming at up to 576 kbps — higher fidelity than standard aptX but below the ceiling of aptX Adaptive or aptX Lossless. Its practical value is limited given that both phones already support the more advanced aptX Adaptive and aptX Lossless standards, which supersede aptX HD in audio quality. Still, it marginally broadens compatibility with older aptX HD-certified headphones that may not support the newer codecs.

This group is essentially a tie. The Poco F7 Ultra's aptX HD inclusion is technically an extra checkmark, but given that both phones share the higher-tier codecs that render it redundant in most real-world scenarios, it does not represent a meaningful practical advantage. Users prioritizing audio quality will be equally well served by either device.

The wireless fundamentals are well matched: both phones support 5G, Wi-Fi 7, NFC, and identical peak download and upload speeds. Where they diverge is in Bluetooth generation — the Poco F7 Ultra ships with Bluetooth 6.0 against the Galaxy S25's 5.4. Bluetooth 6 introduces improved connection stability, lower latency, and enhanced ranging capabilities, which benefits wireless audio, wearables, and accessories. It is a forward-looking advantage that will become more relevant as ecosystem support matures.

SIM flexibility swings firmly toward the Galaxy S25, which supports 2 physical SIMs plus 2 eSIMs simultaneously — a meaningful edge for frequent travelers or users who juggle personal and work lines without swapping physical cards. The F7 Ultra is limited to 2 physical SIMs with no eSIM support. Each phone also holds a unique sensor advantage: the F7 Ultra includes an infrared sensor, enabling it to function as a universal remote for TVs and home appliances, while the S25 carries a barometer for accurate altitude and weather pressure readings — useful for fitness tracking and navigation apps — plus ANT+ support for compatibility with sports and fitness equipment.

This group ends in a nuanced draw with role-specific edges on both sides. The Poco F7 Ultra leads on Bluetooth version and adds IR blaster utility. The Samsung Galaxy S25 counters with superior SIM flexibility, a barometer, and ANT+ support. The better choice depends entirely on which of these features aligns with the user's lifestyle.

The Miscellaneous group offers no differentiation whatsoever between the two phones. Both share a video light, and neither features sapphire glass, a curved display, or an e-paper display. Every data point in this category is identical.

This is a complete tie — the provided specs give no basis for preferring one device over the other in this group.
