Samsung Galaxy S25 Ultra VS ZTE Nubia Red Magic 11 Pro

In terms of physical footprint, the two phones are remarkably close. The Samsung Galaxy S25 Ultra measures 162.8 × 77.6 × 8.2 mm, while the ZTE Nubia Red Magic 11 Pro comes in at 163.8 × 76.5 × 8.9 mm. The Red Magic is fractionally taller and narrower, but its extra 0.7 mm of thickness adds up meaningfully in the hand — and its volume of 111.5 cm³ versus the S25 Ultra's 103.6 cm³ reflects a noticeably bulkier chassis overall. Combined with a 230 g weight against the S25 Ultra's 218 g, the Red Magic is both larger and heavier, which matters during extended single-handed use or gaming sessions.

The more consequential design difference lies in water protection. Both phones carry an IPX8-level water submersion rating, meaning they can withstand immersion in fresh water. However, the S25 Ultra holds a full IP68 certification, which adds a dust-resistance rating (the ″6″ in IP68) that the Red Magic's IPX8 designation explicitly omits. In practice, this means the S25 Ultra offers meaningfully broader environmental protection — relevant in dusty or sandy conditions where the Red Magic provides no certified defense.

Neither device features a rugged build or a foldable form factor, so those dimensions are a wash. Overall, the Samsung Galaxy S25 Ultra holds a clear edge in this group: it is slimmer, lighter, more compact by volume, and offers superior ingress protection with full dust and water certification — a well-rounded advantage for a flagship that prioritizes both ergonomics and durability.

Both phones use OLED/AMOLED panels with Always-On Display support and branded damage-resistant glass, so the baseline display quality is competitive on both sides. The meaningful divergence starts with sharpness: the Samsung Galaxy S25 Ultra delivers a 1440 x 3120 resolution at 498 ppi, versus the Red Magic 11 Pro's 1216 x 2688 at 431 ppi. That 67 ppi gap is perceptible — text renders crisper and fine detail in photos or video is more refined on the S25 Ultra, particularly when viewing content up close.

The Red Magic counters with a 144Hz refresh rate against the S25 Ultra's 120Hz. In gaming, that extra headroom can translate to marginally smoother motion, though the practical difference between 120Hz and 144Hz is subtle for most users and content. More impactful is the S25 Ultra's HDR10+ support — a significant advantage for streaming and media consumption, as it enables dynamic tone mapping for richer highlight and shadow detail. The Red Magic 11 Pro supports neither HDR10 nor HDR10+, meaning it cannot unlock enhanced picture quality on compatible streaming platforms, regardless of the source content.

The Samsung Galaxy S25 Ultra holds a clear overall edge in this category. Its higher resolution, superior pixel density, and HDR10+ certification combine to make it the stronger display for both productivity and media use. The Red Magic's slightly higher refresh rate is a real but narrow advantage that will matter most to competitive mobile gamers, and it is not enough to offset the S25 Ultra's broader display quality lead.

At first glance, these two phones look nearly identical on paper — same 3nm fabrication, same Adreno 830 GPU at 1200 MHz, same memory bandwidth, same storage ceiling. But the chipset names tell a different story: the S25 Ultra runs the Snapdragon 8 Elite, while the Red Magic 11 Pro houses the Snapdragon 8 Elite Gen 5, a newer iteration with slightly higher clock speeds — 4.6 GHz on the performance cores versus 4.47 GHz. The Geekbench 6 results confirm a measurable gap: the Red Magic scores 3234 single-core and 10059 multi-core, compared to the S25 Ultra's 3057 and 9846. These are not dramatic differences in day-to-day tasks, but in sustained workloads like video rendering or extended gaming, the Red Magic's faster silicon gives it a genuine, if modest, throughput advantage.

The more practically significant gap is RAM. The ZTE Nubia Red Magic 11 Pro ships with 24GB of LPDDR5 memory, double the S25 Ultra's 12GB. Both run at the same 5300 MHz speed, so the Red Magic's advantage is in capacity, not bandwidth. More RAM means more apps stay resident in the background without reload, and demanding games or multitasking scenarios have far more headroom before the system starts pruning processes — a meaningful real-world benefit for the power user the Red Magic is clearly aimed at.

The Red Magic 11 Pro takes the edge in this category. Its newer chipset, higher benchmark scores, and doubled RAM capacity combine to make it the stronger performer by the data provided, particularly for users who push their device hard. The S25 Ultra remains an extremely capable processor pairing, but it trails its rival on every measurable performance metric in this group.

The camera systems on these two phones reflect fundamentally different priorities. The Samsung Galaxy S25 Ultra fields a quad-camera array headlined by a 200MP primary sensor, supplemented by two 50MP lenses and a 10MP telephoto, with a 5x optical zoom and laser autofocus. The ZTE Nubia Red Magic 11 Pro offers a more modest triple-camera setup — a 50MP main, a 50MP secondary, and a 2MP auxiliary — with no optical zoom whatsoever. For users who care about versatility and long-range shooting, the S25 Ultra's system is categorically more capable by the data provided.

The technical advantages for the S25 Ultra run deeper than resolution. It includes a BSI sensor (which improves light capture efficiency), laser autofocus for faster subject locking, manual shutter speed control, and HDR10 video recording — none of which are present on the Red Magic. The Red Magic does edge ahead with a slightly wider front camera aperture (f/2.0 versus f/2.2) and a higher-resolution 16MP selfie camera compared to the S25 Ultra's 12MP — a minor but real advantage for selfie quality. Both shoot 8K video at 30fps and share a solid common feature set: OIS, phase-detection autofocus, slow-motion, HDR photo mode, and full manual controls (barring shutter speed on the Red Magic).

The Samsung Galaxy S25 Ultra wins this category decisively. The combination of a higher-resolution main sensor, optical zoom, laser autofocus, BSI sensor technology, and HDR10 video recording gives it a substantially broader and more capable imaging system. The Red Magic's slightly better selfie resolution is a genuine but narrow bright spot that does not alter the overall conclusion.

The most immediate differentiator here is the Android version: the ZTE Nubia Red Magic 11 Pro ships with Android 16, while the Samsung Galaxy S25 Ultra runs Android 15. A newer OS version generally means access to the latest platform security patches, API improvements, and system-level features before they reach older versions — a tangible head start, even if neither device receives direct OS updates according to the provided data.

Beyond the version gap, the S25 Ultra holds a more practical feature advantage in day-to-day use. It supports cross-site tracking blocking, focus modes, Wi-Fi password sharing, and the ability to be used as a PC (desktop mode) — none of which are available on the Red Magic 11 Pro. These are not obscure capabilities: focus modes help manage notifications and distractions, Wi-Fi password sharing is a common convenience feature, and desktop/PC mode meaningfully expands how the device can be used in a productivity context. The Red Magic's absence of cross-site tracking blocking is also a mild privacy disadvantage for users who browse the web regularly.

This category is a genuine split. The Red Magic 11 Pro has the newer OS, which carries real value for security and platform currency. But the Samsung Galaxy S25 Ultra offers a richer feature set at the OS level, with several capabilities — particularly desktop mode and focus modes — that serve users across both productivity and daily convenience. For most users, the S25 Ultra's broader software feature set tips the balance in its favor, though users who prioritize having the latest Android version will find the Red Magic's advantage meaningful.

The battery gap between these two phones is substantial. The ZTE Nubia Red Magic 11 Pro packs a 7500 mAh cell — 50% larger than the Samsung Galaxy S25 Ultra's 5000 mAh. All else being equal, a bigger battery translates directly to more hours between charges, and a 2500 mAh difference is not marginal — it is the kind of gap that can mean the difference between needing a top-up mid-afternoon versus comfortably reaching the end of a heavy-use day.

Charging tells a similarly lopsided story. The Red Magic supports 80W wired fast charging, nearly double the S25 Ultra's 45W. More striking still, its wireless charging also runs at 80W — an unusually fast wireless speed — while the S25 Ultra caps wireless at 15W. The practical upshot is that the Red Magic not only holds more charge, it replenishes that larger battery significantly faster. The S25 Ultra does offer one exclusive here: reverse wireless charging, allowing it to top up accessories like earbuds or a smartwatch. The Red Magic has no equivalent capability.

The Red Magic 11 Pro wins this category clearly and by a wide margin. A 50% larger battery combined with nearly double the wired charging speed and dramatically faster wireless charging make it the stronger device for users who prioritize endurance and fast top-ups. The S25 Ultra's reverse wireless charging is a useful convenience, but it does not come close to offsetting the Red Magic's commanding lead in raw battery capacity and charging performance.

Audio connectivity is where these two phones diverge most sharply, and it comes down to a classic tradeoff. The ZTE Nubia Red Magic 11 Pro includes a 3.5mm headphone jack, while the Samsung Galaxy S25 Ultra does not. For users with wired headphones — whether for gaming, studio monitoring, or simply preferring the reliability of a physical connection — the Red Magic's jack is a meaningful practical advantage that eliminates the need for dongles or adapters entirely.

The S25 Ultra counters with superior wireless audio codec support: it carries both aptX and aptX HD, which enable higher-quality Bluetooth audio transmission with lower latency and greater dynamic range when paired with compatible headphones. The Red Magic supports neither, meaning Bluetooth audio quality is limited to more standard codecs. For wireless headphone users who own aptX-compatible gear, the S25 Ultra delivers a noticeably richer listening experience over Bluetooth. Both phones share stereo speakers and neither includes a radio, so those dimensions are equal.

This category is a genuine split that depends entirely on how a user listens. Wired headphone users will find the Red Magic 11 Pro's headphone jack indispensable, while wireless audio enthusiasts with aptX-compatible headphones will get more from the S25 Ultra's codec support. Neither phone holds an unconditional advantage — the right answer depends on the user's audio setup.

Core wireless connectivity is essentially identical between these two phones — both support 5G, Wi-Fi 7, Bluetooth 5.4, NFC, USB 3.2 Type-C, and matching peak download and upload speeds. For most users, neither phone will feel faster or more connected than the other in everyday wireless use. Where the specs diverge is in the finer details of what each device brings beyond the networking fundamentals.

The Samsung Galaxy S25 Ultra differentiates itself in several practical ways. It supports 2 physical SIMs plus 2 eSIMs, offering significantly more flexibility for users who travel internationally or maintain separate personal and work lines — the Red Magic 11 Pro is limited to 2 physical SIMs with no eSIM support. The S25 Ultra also includes a built-in stylus, a barometer for environmental sensing, and ANT+ support for fitness accessory connectivity. The Red Magic 11 Pro counters with one exclusive of its own: an infrared sensor, which allows the phone to function as a universal remote for TVs and other IR-controlled appliances — a niche but genuinely useful feature the S25 Ultra lacks.

The Samsung Galaxy S25 Ultra holds the broader advantage in this category. Its eSIM support alone is a meaningful differentiator for frequent travelers, and the bundled stylus adds an input capability the Red Magic cannot match. The Red Magic's infrared sensor is a handy extra, but it addresses a narrower use case and does not offset the S25 Ultra's more substantial connectivity and feature lead.

The Miscellaneous spec group for these two phones yields a straightforward result: every data point is identical. Both the Samsung Galaxy S25 Ultra and the ZTE Nubia Red Magic 11 Pro include a video light, and neither features sapphire glass, a curved display, or an e-paper display. There is nothing in this group that separates one device from the other.

This is a complete tie by the provided data. Neither phone holds any advantage here, and users should weigh other specification groups when making their decision.
