Nothing Phone (3a) VS Vivo T4 5G

Both phones share the same overall footprint in terms of height — 163.5 mm vs 163.4 mm — and weigh virtually the same at 201 g and 199 g respectively, making neither a clear winner on sheer size or heft. In day-to-day handling, these differences are imperceptible. Where the gap becomes more tangible is thickness: the Vivo T4 5G is measurably slimmer at 7.9 mm compared to the Nothing Phone (3a)'s 8.4 mm, a 0.5 mm difference that, combined with its slightly narrower width, yields a noticeably smaller total volume (98.6 cm³ vs 106.4 cm³). That roughly 8% reduction in volume gives the Vivo a more compact, premium-feeling profile in the hand.

On water and dust resistance, both carry an IP6X rating for dust, but the second digit tells a different story. The Nothing Phone (3a) is rated IP64, meaning it resists water splashing from any direction — fine for rain or an accidental sink splash. The Vivo T4 5G steps up to IP65, which adds protection against sustained, low-pressure water jets. In practical terms, this means the Vivo can handle a more aggressive rinse under a tap without concern, while the Nothing Phone (3a) should be kept away from direct streams of water.

The Vivo T4 5G holds a clear edge in this category. Its slimmer, more compact build and superior IP65 rating make it the more refined and resilient of the two from a design standpoint, even if the differences in weight and height are essentially irrelevant in real-world use.

At the panel level, these two phones are essentially identical: both feature a 6.77″ OLED/AMOLED display running at 1080 x 2392 px, 120Hz, and a pixel density so close — 387 vs 388 ppi — that it is a non-factor. The shared foundation means both deliver the same punchy colors, deep blacks, and smooth scrolling you expect from a mid-range AMOLED in 2024.

The differentiators, however, pull in opposite directions. The Vivo T4 5G pulls ahead on outdoor usability with a typical brightness of 1300 nits, a significant step above the Nothing Phone (3a)'s 800 nits. That 62% brightness advantage translates directly to better legibility in sunlight — a spec that matters every single day. The Vivo also includes branded damage-resistant glass, adding a layer of real-world durability the Nothing Phone (3a) lacks. On the other side of the ledger, the Nothing Phone (3a) supports HDR10 and HDR10+, enabling richer tone-mapping and a wider dynamic range when streaming compatible content — something the Vivo entirely foregoes.

The edge ultimately goes to the Vivo T4 5G. Brightness and screen durability are everyday concerns, while HDR10+ content — though genuinely beneficial — is less consistently impactful in typical usage. For most users, the Vivo's superior brightness and glass protection will matter more, more often.

This is a rare case of a complete dead heat. Both phones run on the Qualcomm Snapdragon 7s Gen 3 — a capable 4nm mid-range chip — paired with 12GB of RAM and 256GB of internal storage. The benchmark numbers confirm what the shared silicon implies: identical Geekbench 6 multi-core scores of 3239 and single-core scores of 1162, with no measurable daylight between them across any test.

Every meaningful performance variable — GPU model, clock speeds, memory bandwidth, TDP, DDR version — is duplicated exactly. Users can expect the same experience whether they are multitasking, gaming, or running demanding apps. Neither phone will throttle differently, run cooler, or sustain peak performance longer than the other, at least as far as the provided specs indicate.

This category is an unambiguous tie. Performance cannot be a deciding factor between these two phones — the hardware is, for all practical purposes, the same.

The camera systems diverge significantly in ambition. The Nothing Phone (3a) fields a triple rear camera setup (50 + 50 + 8 MP) against the Vivo T4 5G's dual-lens system (50 + 2 MP). The Vivo's secondary 2MP sensor is effectively a depth assistant — it contributes little on its own. The Nothing, by contrast, pairs its main 50MP shooter with a second full-resolution 50MP lens, and adds an 8MP wide for scene flexibility. That second 50MP sensor is also what enables the Nothing's 2x optical zoom, a genuine hardware zoom that preserves detail when shooting at distance — a capability the Vivo entirely lacks, rated at 0x optical zoom.

Shared ground includes OIS on both, identical 4K/30fps video ceilings, phase-detection autofocus, and a matching 32MP front camera. The front aperture slightly favors the Vivo at f/2.0 vs the Nothing's f/2.2, which in theory allows marginally more light in low-light selfie situations — a minor but real advantage in dimmer environments.

The Nothing Phone (3a) wins this category clearly. A versatile triple-camera array, a dedicated high-resolution telephoto lens, and genuine optical zoom give it a meaningfully broader photographic range. The Vivo's camera system is competent for everyday shots but cannot match the Nothing's flexibility across different shooting scenarios.

When two phones share not just an OS version but every single feature flag in the dataset, the comparison becomes a statement in itself. Both run Android 15 and match each other point for point across privacy controls, productivity features, and system capabilities — from on-device machine learning and dynamic theming to split-screen multitasking, Picture-in-Picture, and offline voice recognition.

This is a complete tie. Based strictly on the provided specifications, there is no software feature that distinguishes one phone from the other. A user prioritizing any particular OS capability — privacy, customization, accessibility, or productivity — will find identical support on both devices.

Battery is where the Vivo T4 5G makes its most emphatic statement. Its 7300 mAh cell is an exceptionally large capacity for a mid-range phone — 46% larger than the Nothing Phone (3a)'s already-respectable 5000 mAh. In practical terms, a battery of that size on the same 4nm chipset points strongly toward multi-day endurance for moderate users, and a meaningful buffer even under heavy loads like gaming or navigation. The Nothing's 5000 mAh is a solid industry-standard figure that reliably delivers a full day, but it simply cannot compete at this scale.

The charging story compounds the Vivo's advantage further. At 90W, it charges nearly twice as fast as the Nothing Phone (3a)'s 50W — and it starts from a much larger tank. That combination means the Vivo spends less time tethered to a cable despite having more capacity to fill. Neither phone supports wireless charging, so that is a wash.

The Vivo T4 5G wins this category decisively. A larger battery and faster wired charging together represent a genuinely meaningful real-world advantage — one that affects daily routine in ways that most spec differences simply do not.

The audio specs are lean on both sides, but one distinction stands out: the Nothing Phone (3a) has stereo speakers, while the Vivo T4 5G does not. Stereo output — sound from two separate drivers — creates a noticeably wider soundstage for media consumption, gaming, and speakerphone calls. On a mono speaker, all audio collapses to a single point of origin, which makes the experience feel comparatively flat, especially when watching video content in landscape orientation.

Everything else is shared territory, and not particularly flattering for either phone. Neither offers a 3.5mm headphone jack, lossless Bluetooth audio codecs like LDAC or aptX, or an FM radio. Wired audio users will need a USB-C adapter, and Bluetooth audiophiles get no high-fidelity codec support on either device.

The Nothing Phone (3a) takes a clear edge here solely on the strength of its stereo speaker setup. It is a single but meaningful differentiator — one that affects everyday media use far more than the absence of features both phones equally lack.

The connectivity foundations are identical: both phones support 5G, Wi-Fi 6, dual SIM, USB Type-C, and GPS with Galileo. Where they diverge is in two features that swap advantages between the devices. The Nothing Phone (3a) includes NFC — essential for contactless payments, transit cards, and device pairing — while the Vivo T4 5G omits it entirely. For users who rely on tap-to-pay or NFC-based workflows, this is a daily-use gap that cannot be worked around. The Nothing also runs Bluetooth 5.4 against the Vivo's 5.2, a newer version that brings modest improvements to connection stability and efficiency, though the practical difference in everyday use is minor.

The Vivo counters with an infrared sensor, which lets the phone function as a universal remote for TVs, air conditioners, and other IR-controlled appliances — a convenience feature the Nothing Phone (3a) lacks. It is genuinely useful for those who want it, but it serves a narrower set of use cases compared to NFC.

The Nothing Phone (3a) edges ahead in this category. NFC is a broadly relevant, frequently used feature in modern smartphone life, and its absence on the Vivo is a more consequential omission than the lack of an IR blaster on the Nothing. The newer Bluetooth version is a secondary but directionally consistent advantage for the Nothing as well.

The miscellaneous specs offer nothing to separate these two phones — every data point is identical. Both have a video light, neither features sapphire glass, a curved display, or an e-paper panel. This is a straightforward tie with no differentiating factor present in the provided data.
