ZTE Nubia Z70S Ultra VS ZTE Nubia Z80 Ultra

In terms of physical design, the Z70S Ultra and Z80 Ultra are remarkably close siblings. Both share identical 8.6 mm thickness and near-identical footprints — the Z80 Ultra is marginally taller (164.5 mm vs 164.3 mm) and fractionally wider (77.2 mm vs 77.1 mm). These sub-millimeter differences are imperceptible in hand and have no practical impact on one-handed usability or pocket comfort.

Weight tells a similar story: the Z70S Ultra comes in at 228 g versus the Z80 Ultra's 227 g — a single gram apart, which is far below the threshold of human perception. Both devices fall into the ″hefty flagship″ category, so users sensitive to weight will feel the same heft regardless of which model they choose. On the protection front, both carry a full IP68 rating, meaning equivalent dust and water resistance suitable for submersion up to 1.5 meters — a genuine shared strength rather than a differentiator.

Overall, the Design category is effectively a tie. There is no meaningful real-world distinction between these two devices in build dimensions, weight, or protection level. A buyer choosing between them should look entirely to other spec groups — display, performance, or cameras — to find a deciding factor, as physical design offers no advantage to either side.

The two displays are built from the same foundation: a 6.85″ OLED/AMOLED panel running at 1216 x 2688 px with a pixel density of 431 ppi and a 144Hz refresh rate. At that pixel density, sharpness is beyond reproach — text and fine detail are indistinguishable from print at normal viewing distances. The 144Hz rate ensures fluid scrolling and responsive gaming on both devices equally.

The sole differentiator in this group is HDR10+ support, which the Z80 Ultra has and the Z70S Ultra lacks. Where HDR10 uses static metadata to set brightness and color parameters once per video stream, HDR10+ applies dynamic metadata — adjusting tone-mapping scene by scene or even frame by frame. In practice, this means compatible content on the Z80 Ultra can render deeper shadow detail and more nuanced highlights, particularly in high-contrast sequences, rather than clipping bright or dark areas to a fixed profile.

The Z80 Ultra holds a narrow but genuine edge here. HDR10+ content is still growing in availability, so the advantage is not transformative today, but it is a meaningful future-proofing differentiator for users who consume a lot of HDR video from platforms that have adopted the standard. For everything else — everyday brightness, color accuracy, smoothness — both screens are functionally identical.

Both phones are undeniably flagship-tier, but they are not powered by the same chip. The Z70S Ultra runs on the Snapdragon 8 Elite, while the Z80 Ultra steps up to the Snapdragon 8 Elite Gen 5 — a newer generation with meaningfully higher clock speeds: 4.6 GHz on the prime cores versus 4.32 GHz, and 3.62 GHz on the efficiency cores versus 3.53 GHz. The GPU also runs faster on the Z80 Ultra, with an Adreno 830 clocked at 1200 MHz compared to 1100 MHz on the Z70S Ultra — a roughly 9% GPU clock advantage that could matter in sustained, GPU-heavy workloads like high-fidelity gaming.

The Geekbench 6 scores complicate the narrative, however: both devices return identical results of 10059 (multi-core) and 3234 (single-core). This suggests that in typical burst workloads the clock speed advantage of the Gen 5 does not yet translate to measurable real-world throughput gains in this benchmark, though sustained performance under thermal load may still diverge. Where the Z70S Ultra fights back is RAM: it ships with 24 GB versus the Z80 Ultra's 16 GB, giving it a tangible advantage for heavy multitasking, keeping more apps live in the background, and future-proofing against increasingly memory-hungry applications.

The verdict here is a nuanced split. The Z80 Ultra has the architectural edge — a newer SoC with higher peak clocks — making it the stronger choice for users who push the GPU hard. The Z70S Ultra counters with a substantial RAM advantage that benefits multitaskers and power users who juggle many apps simultaneously. Neither product dominates outright; the right choice depends on whether raw processing headroom or memory capacity matters more to the individual user.

The camera hardware on paper looks nearly identical — identical megapixel counts across all three rear lenses (64 & 50 & 50 MP), the same 2.7x optical zoom, and a matching 4320p / 30fps video ceiling. The real story is in the apertures. The Z80 Ultra edges ahead on the primary lens (f/2.4 vs f/2.5) and more notably on the third lens (f/1.8 vs f/2.0), which at telephoto distances translates to meaningfully more light reaching the sensor — an advantage in low-light zoom photography. Its front camera is also wider at f/2.0 versus f/2.5, benefiting selfie performance in dim conditions.

The Z70S Ultra counters with two distinct advantages. Its ultra-wide minimum focal length reaches 13 mm compared to the Z80 Ultra's 18 mm — a significant difference that captures a far broader field of view, making it the stronger tool for architecture, landscapes, and tight indoor spaces. It also supports Dolby Vision recording, while the Z80 Ultra does not. For videographers delivering content to Dolby Vision-compatible platforms and displays, that is a genuine pipeline advantage, as Dolby Vision encodes dynamic HDR metadata at a higher tier than HDR10 alone.

This group produces a genuine split decision. The Z80 Ultra has the low-light photography edge thanks to wider apertures across multiple lenses. The Z70S Ultra wins on versatility — its dramatically wider ultra-wide reach and Dolby Vision video support make it the more capable tool for shooters who prioritize creative range and professional video output. Still photographers in dim environments lean toward the Z80 Ultra; videographers and wide-angle enthusiasts lean toward the Z70S Ultra.

Strip away the single version number difference and the software profiles of these two devices are carbon copies of each other — every feature flag in the provided data is identical across privacy controls, multitasking capabilities, accessibility options, and productivity tools. The one thing that separates them is the foundation they run on: the Z70S Ultra ships with Android 15, while the Z80 Ultra ships with Android 16.

That generational gap matters more than it might seem at launch. A newer Android version typically brings refined permission models, updated privacy and security patches baked into the base OS, and optimizations that app developers will increasingly target. Critically, both devices are listed as not receiving direct OS updates, meaning users on the Z70S Ultra are starting one full version behind with no guaranteed path to close that gap — a meaningful consideration for anyone planning to hold their device for two or more years.

The Z80 Ultra holds a clear edge here. With an identical feature set but a newer OS version from day one, it offers a fresher security baseline and better long-term software relevance. For users who care about staying current — especially given neither phone gets direct OS updates per the provided data — starting on Android 16 rather than Android 15 is a tangible, if understated, advantage.

Battery is one of the clearest wins for either device across the entire comparison. The Z80 Ultra packs a 7200 mAh cell against the Z70S Ultra's 6600 mAh — a 600 mAh difference that represents roughly a 9% larger reserve. On a device running a power-hungry flagship chipset and a 144Hz display, that margin is likely to translate into a meaningful buffer at the end of a heavy day, potentially the difference between reaching for a charger before bed or not.

The Z80 Ultra also charges faster at 90W versus 80W, meaning a larger battery that also refills more quickly — a combination that compounds the advantage. More significantly, it adds wireless charging, a feature entirely absent on the Z70S Ultra. Wireless charging at this tier is less about speed and more about convenience — dropping the phone on a pad overnight or on a desk charger without managing cables is a quality-of-life upgrade that wired-only users notice daily once they have experienced it.

The Z80 Ultra wins this category convincingly and without qualification. A bigger battery, faster wired charging, and the addition of wireless charging represent a clean sweep across every meaningful battery metric. For users who treat endurance and charging flexibility as priorities — and most do — this group alone gives the Z80 Ultra a compelling practical advantage.

For wireless audio, both devices share a strong common baseline — stereo speakers and support for aptX, aptX HD, and aptX Adaptive. The meaningful divergence is a single codec: the Z70S Ultra supports aptX Lossless, while the Z80 Ultra does not. aptX Lossless is the top tier of Qualcomm's audio stack, capable of transmitting CD-quality audio at true lossless bit depth over Bluetooth when paired with compatible headphones. For audiophiles using lossless-capable wireless headphones, this is a genuine capability gap — the Z70S Ultra can deliver bit-perfect audio wirelessly, while the Z80 Ultra tops out at aptX Adaptive's high-quality but still lossy compression.

Outside of that codec distinction, the two phones are identical in audio terms. Neither includes a 3.5 mm headphone jack, so wired listening requires an adapter or USB-C headphones on both devices. Stereo speakers are present on both, ensuring a balanced front-facing soundstage for media consumption.

The Z70S Ultra takes this category on the strength of aptX Lossless support alone. It is a niche advantage — it only activates with compatible accessories and lossless audio sources — but among dedicated wireless audio enthusiasts, it represents a ceiling that the Z80 Ultra simply cannot reach. For casual listeners, the gap is irrelevant; for those who have invested in a high-end Bluetooth audio setup, it is a concrete differentiator in favor of the Z70S Ultra.

Connectivity is the most evenly matched category in this entire comparison. Both devices support 5G, Wi-Fi 7 (the latest standard, offering significantly higher throughput and lower latency than Wi-Fi 6E), Bluetooth 5.4, NFC, and USB 3.2 Type-C — covering every modern connectivity standard a flagship user would expect. The Wi-Fi version strings for the two phones list the same standards in a slightly different order, but the supported protocols are identical in substance.

The sensor suites are equally matched: both include GPS with Galileo support, gyroscope, accelerometer, compass, infrared sensor, and a fingerprint scanner. Neither phone offers a barometer, satellite SOS, or crash detection — notable shared omissions for users coming from devices that include those safety-oriented features. The dual-SIM configuration is also shared, which is a practical convenience for users who need to separate work and personal lines or maintain a local data SIM while traveling.

This group is a complete tie. There is no differentiating feature, missing capability, or spec advantage on either side — every connectivity and sensor data point in the provided specs is identical across both devices. Buyers looking for a reason to choose between the Z70S Ultra and Z80 Ultra will need to look entirely to the other spec groups, as connectivity and features offer no basis for distinction whatsoever.

The Miscellaneous group is the briefest in this comparison, and it delivers the same verdict as Connectivity before it: a complete tie. Both the Z70S Ultra and Z80 Ultra share every data point here — a video light is present on each, and neither features a sapphire glass display, a curved screen, or an e-paper panel.

The shared video light is worth a brief note — it serves as a continuous illumination source for video recording rather than a single-burst flash, a thoughtful inclusion for content creators shooting in low-light environments. The absence of a curved display on both is equally consistent with current flagship trends moving away from edge-curved screens toward flat panels, which typically offer better touch accuracy and screen protector compatibility.

With no differentiating data point present in this group, it is a tie by definition. Neither device carries any miscellaneous feature advantage over the other, and this category has no bearing on the overall purchase decision between the two.
