Vivo iQOO Neo 10 VS Vivo T4 Ultra 5G

In terms of physical footprint, the Vivo T4 Ultra 5G is the more compact and lighter device. At 192 g and 7.5 mm thick, it is notably slimmer and 14 grams lighter than the iQOO Neo 10, which comes in at 206 g and 8.1 mm. The difference in volume reinforces this gap: the T4 Ultra displaces roughly 90.3 cm³ versus the Neo 10's 100.6 cm³. In real-world use, this translates to a phone that feels meaningfully less bulky in hand and in a pocket — a genuine ergonomic advantage for users who prioritize one-handed comfort or all-day carry.

On water protection, however, the iQOO Neo 10 holds a clear edge. Its IP65 rating means it is fully dust-tight and can withstand sustained water jets from any direction, which earns it the ″Waterproof″ designation. The T4 Ultra's IP64 rating is also fully dust-tight but is only rated against water splashes — not directed jets — landing it in the lower ″Water resistant″ category. For users who frequently use their phone outdoors, near sinks, or in rain, this difference is practically significant.

Neither phone offers a rugged build or a foldable form factor, so both target the same conventional smartphone use case. Overall, the T4 Ultra wins on portability and comfort, while the Neo 10 wins on environmental protection. The better choice depends on priorities: if slim, lightweight design matters most, the T4 Ultra has the edge; if durability against water exposure is paramount, the iQOO Neo 10 is the stronger option.

Both phones use OLED/AMOLED panels and share an identical 1260 x 2800 px resolution, so the foundation of display quality is the same. The iQOO Neo 10's larger 6.78″ screen gives it more real estate for media and multitasking, while the T4 Ultra's slightly smaller 6.67″ panel squeezes the same pixel count into a tighter area, yielding a marginally higher pixel density of 460 ppi versus 453 ppi. In practice, both are sharp well beyond the threshold of human perception at normal viewing distances, so this difference is not meaningful to the naked eye.

Where the iQOO Neo 10 pulls ahead more decisively is in refresh rate and HDR support. Its 144Hz refresh rate produces noticeably smoother scrolling and animations compared to the T4 Ultra's 120Hz — a difference that is perceptible during fast-paced gaming or quick UI navigation. More significantly, the Neo 10 supports both HDR10 and HDR10+, enabling richer contrast and dynamic tone-mapping when streaming compatible content on platforms like YouTube or Prime Video. The T4 Ultra supports neither standard, meaning it will render that same content without the expanded dynamic range.

The iQOO Neo 10 holds a clear advantage in this category. The combination of a higher refresh rate and full HDR support makes it the stronger choice for users who prioritize display performance — particularly for gaming and video consumption. The T4 Ultra's display is capable and sharp, but it lacks the features that elevate the viewing experience on the Neo 10.

On the surface, these two phones appear almost identically matched: their AnTuTu scores are separated by fewer than 2,000 points (2,135,100 vs 2,136,863), and they share the same 4 nm fabrication node, DDR5 memory, and identical peak memory bandwidth of 76.8 GB/s. However, the chipset architectures diverge in ways that matter. The T4 Ultra's Dimensity 9300 Plus posts meaningfully higher Geekbench 6 scores — 2302 single-core and 7547 multi-core — compared to the Neo 10's Snapdragon 8s Gen 4 at 2041 and 6833 respectively. That single-core gap is particularly relevant for everyday responsiveness, since most app interactions and UI tasks are single-threaded workloads.

The T4 Ultra also holds a structural advantage in cache architecture, with a substantially larger 18 MB L3 cache (versus 8 MB on the Neo 10) and a bigger L2 cache as well. Larger caches reduce how often the CPU has to reach out to slower main memory, which can translate to smoother sustained performance under load. Its GPU clock speed of 1300 MHz also edges out the Neo 10's 1150 MHz, suggesting a slight graphics throughput advantage. The Neo 10 counters with 16 GB of RAM versus 12 GB on the T4 Ultra, which gives it more headroom for aggressive multitasking and keeping more apps resident in memory simultaneously.

The T4 Ultra has a narrow but consistent edge in raw CPU and GPU performance metrics, making it the stronger choice for compute-intensive tasks and gaming. The Neo 10's higher RAM capacity is a practical advantage for power multitaskers, but does not close the gap in processing throughput. For pure performance, the T4 Ultra leads — though both phones operate at a flagship-adjacent tier where real-world differences will be subtle for most users.

The most structurally significant difference here is that the T4 Ultra fields a triple rear camera — 50 MP + 50 MP + 8 MP — while the iQOO Neo 10 carries a dual rear camera at 50 MP + 8 MP. That extra 50 MP sensor on the T4 Ultra is what enables its 3x optical zoom, a capability the Neo 10 entirely lacks (rated at 0x). Optical zoom is a meaningful real-world advantage: it preserves image detail when shooting subjects at a distance, whereas digital zoom on the Neo 10 simply crops and degrades the image. For travel, events, or portrait shooting with subject separation, this gives the T4 Ultra a genuine versatility edge.

The Neo 10 strikes back on video. Its main camera is capable of recording at 2160p at 60 fps, versus the T4 Ultra's cap of 2160p at 30 fps. Shooting 4K at 60 frames per second produces significantly smoother footage — especially for action, sports, or any scene with motion — making the Neo 10 the stronger option for videographers. Both phones share OIS, phase-detection autofocus, continuous autofocus during recording, and a comparable manual controls suite, so the gap is specifically about frame rate ceiling.

This is a trade-off comparison rather than a clean win for either side. The T4 Ultra is the more capable still photography system thanks to its third lens and optical zoom. The Neo 10 is the better video device, offering higher frame rates at 4K. Users who shoot a lot of photos — particularly at range — will favor the T4 Ultra, while those who prioritize smooth video capture will find the Neo 10 more suited to their needs.

This is a rare case of a complete tie. Every single operating system specification provided is identical across the Vivo iQOO Neo 10 and the Vivo T4 Ultra 5G. Both run Android 15, both lack direct OS updates, and both offer the same privacy controls — including location, camera, and microphone permission management, app tracking blocks, and clipboard warnings. Neither device supports cross-site tracking protection or Wi-Fi password sharing, and neither can function as a PC replacement.

On the usability and features side, the picture is equally uniform: both support split-screen multitasking, Picture-in-Picture, dynamic theming, dark mode, widgets, full-page screenshots, offline voice recognition, and multi-user profiles. Practically speaking, a user switching between these two devices would notice no difference whatsoever at the software layer — the experience, capabilities, and limitations are point-for-point the same.

Given the data provided, this category is a dead tie. Neither phone holds any software advantage over the other, and the operating system should not factor into a decision between these two devices.

Battery capacity is where the iQOO Neo 10 establishes one of its clearest advantages across the entire comparison. Its 7000 mAh cell is a genuinely large battery by any standard — 1500 mAh more than the T4 Ultra's already-respectable 5500 mAh. That 27% capacity gap translates directly into more screen-on time between charges, greater resilience during heavy usage days, and less dependency on finding a power outlet. For users who travel frequently, work long shifts, or simply dislike the anxiety of a draining battery, the Neo 10's cell size is a tangible, everyday benefit.

On charging speed, the Neo 10 also leads with 120W fast charging versus the T4 Ultra's 90W. Faster wattage means shorter time tethered to a cable — and critically, with a larger battery to fill, the higher wattage helps offset what would otherwise be a longer absolute charge time. Both phones include a charger in the box and support fast charging as a standard feature, so neither user faces an unexpected additional purchase. Wireless charging is absent on both devices.

The iQOO Neo 10 wins this category decisively. It delivers both greater battery capacity and faster wired charging, a combination that covers the full spectrum of battery convenience — longer life between charges and quicker recovery when it does run low. The T4 Ultra's 5500 mAh is a solid figure, but it cannot match the Neo 10's endurance-focused setup.

Audio is another category where the two devices are completely identical across every provided specification. Both the iQOO Neo 10 and the T4 Ultra feature stereo speakers and omit a 3.5 mm headphone jack — a now-common trade-off in modern mid-to-upper-range smartphones that pushes users toward Bluetooth or USB-C audio. Neither device supports any high-resolution Bluetooth audio codec, including aptX, aptX HD, aptX Adaptive, LDAC, or aptX Lossless, and neither includes an FM radio.

The absence of advanced wireless audio codecs is worth noting for audiophiles who use high-fidelity Bluetooth headphones. Codecs like LDAC or aptX Lossless can transmit significantly more audio data over Bluetooth than the standard SBC codec, resulting in better sound quality through compatible headphones. Since neither phone supports these, both are limited to standard Bluetooth audio quality regardless of the headphones paired with them.

This category is a complete tie. The shared stereo speaker setup is a meaningful positive for media consumption, but the identical codec limitations mean neither phone has any advantage for wireless audio quality. Audio performance should play no role in choosing between these two devices.

Two differences stand out immediately in opposite directions. The iQOO Neo 10 supports Wi-Fi 7 (802.11be), while the T4 Ultra tops out at Wi-Fi 6 — a meaningful generational gap for users with a compatible router. Wi-Fi 7 offers substantially higher throughput and lower latency, which matters for 4K streaming, large file transfers, and cloud gaming at home. Meanwhile, the T4 Ultra flips the advantage on cellular, with peak download and upload speeds of 10,000 / 7,000 Mbits/s versus the Neo 10's 4,200 / 3,500 Mbits/s. That is more than double the theoretical cellular throughput — relevant in 5G mmWave environments where network speeds can actually approach those limits.

A smaller but practical distinction: the Neo 10 includes an infrared sensor, which allows it to function as a universal remote for TVs, air conditioners, and other IR-controlled appliances. The T4 Ultra omits this entirely. For users who value this kind of everyday utility, it is a genuine convenience the T4 Ultra simply cannot replicate. Everything else — Bluetooth 5.4, NFC, dual SIM, USB-C, GPS, Galileo, gyroscope, accelerometer, and fingerprint scanner — is shared between both phones.

This category does not have a single clear winner; rather, each phone leads in a different connectivity dimension. The Neo 10 is the stronger choice for Wi-Fi-heavy households and users who want IR remote functionality. The T4 Ultra is better suited for users who prioritize maximum cellular data speeds on 5G networks. The decision comes down to which connectivity scenario is more relevant to how the phone will actually be used.

The miscellaneous specification group offers no differentiating information between these two devices. Every data point provided — the presence of a video light, and the absence of a sapphire glass display, curved display, or e-paper display — is identical across both the iQOO Neo 10 and the T4 Ultra.

This is a complete tie with no meaningful basis for comparison. This category should carry no weight in a purchasing decision between these two phones.
