Infinix Note 50s 5G VS Vivo T4x 5G

Both the Infinix Note 50s 5G and the Vivo T4x 5G share the same IP64 ingress protection rating, meaning each offers equivalent resistance to dust and water splashes. Neither carries a rugged build certification, and neither is foldable, so on those fronts they are perfectly matched.

Where the two phones meaningfully diverge is in their physical footprint. The Infinix is noticeably slimmer at 7.6 mm versus the Vivo's 8.1 mm, and lighter at 180 g compared to 204 g — a 24-gram gap that is genuinely perceptible during extended one-handed use or long calls. The Infinix is also marginally narrower (74.5 mm vs. 76.3 mm) and shorter (164.3 mm vs. 165.7 mm), which compounds into a total volume of roughly 93 cm³ against the Vivo's 102 cm³. In practical terms, the Infinix will feel less fatiguing to hold over time and will sit more comfortably in a pocket.

On design, the Infinix Note 50s 5G holds a clear edge. Its combination of lower weight, reduced thickness, and smaller overall volume makes it the more compact and ergonomic choice — an advantage that matters daily, even if the Vivo's extra bulk could hint at a larger battery or other internal trade-offs addressed elsewhere in the spec sheet.

The single most consequential difference here is panel technology. The Infinix Note 50s 5G uses an OLED/AMOLED display, while the Vivo T4x 5G relies on an LCD IPS panel. In everyday use this translates to deeper blacks, higher contrast, and more vivid colors on the Infinix — OLED achieves true blacks by turning pixels off entirely, something LCD fundamentally cannot do. It also enables the Infinix's Always-On Display feature, which lets glanceable information remain visible without meaningfully draining the battery, a convenience the Vivo simply cannot offer.

Screen size and pixel density are effectively a wash — 6.78″ vs. 6.72″ and an identical 393 ppi on both — so sharpness is not a differentiator. The refresh rate, however, does add another point in the Infinix's favor: its 144Hz panel delivers visibly smoother scrolling and animations compared to the Vivo's 120Hz, a difference that is subtle but noticeable for users who interact heavily with fast-scrolling feeds or gaming. The Infinix also ships with branded damage-resistant glass, adding a layer of scratch protection the Vivo lacks.

The Infinix Note 50s 5G wins this category decisively. The AMOLED panel alone is a generational step above LCD in display quality, and the advantages in refresh rate, Always-On Display, and glass protection only reinforce that lead. For display-conscious buyers, the Vivo T4x 5G does not compete on equal footing here.

Rarely does a performance comparison come down to this level of parity. Both phones are powered by the identical MediaTek Dimensity 7300 chipset — same 4 nm fabrication, same CPU configuration, same Mali G615 MC2 GPU at the same clock speed, same 8GB of DDR5 RAM running at 6400 MHz, and the same 256GB of internal storage. When the silicon is literally the same, the benchmark scores are the only empirical differentiator.

And those scores are remarkably close. The Vivo T4x 5G edges ahead on AnTuTu with 685,000 versus the Infinix's 675,134 — a gap of under 1.5% that will never be felt in real-world usage. Geekbench 6 tells a slightly different story: the Infinix pulls ahead on multi-core performance (2,932 vs. 2,827), while the Vivo's single-core result is fractionally higher (1,031 vs. 1,026). These variations almost certainly reflect differences in software optimization and thermal management rather than any meaningful hardware distinction.

This category is an unambiguous tie. Choosing between these two phones on performance grounds is not a rational basis for a decision — day-to-day app launches, multitasking, and gaming will feel indistinguishable on either device. Buyers should let other spec groups, such as display or design, drive their choice.

Starting with the main camera, the Infinix Note 50s 5G packs a 64MP primary sensor against the Vivo T4x 5G's 50MP shooter — a meaningful resolution gap that gives the Infinix more detail headroom for cropping and large-format prints. The aperture picture is also tilted in the Infinix's favor: its main lens opens to a consistent f/1.8, while the Vivo's primary lens is a narrower f/2.4 (with its secondary lens matching f/1.8). A wider aperture on the main sensor directly improves light intake, which matters most in low-light and indoor conditions. Both phones top out at the same 4K 30fps video ceiling and share an identical feature set across autofocus, HDR, slow-motion, and manual controls, so the practical shooting experience is otherwise comparable.

The selfie camera gap is equally notable. The Infinix offers a 13MP front sensor versus the Vivo's 8MP — a 60% resolution advantage that translates to sharper self-portraits and cleaner video calls. The Vivo's front aperture is fractionally wider (f/2.1 vs. f/2.2), but this marginal difference is unlikely to offset the resolution disadvantage in most scenarios. Additionally, the Infinix features a dual-tone LED flash on the rear versus the Vivo's single LED, which helps produce more natural-looking flash-lit shots by mixing warm and cool tones.

The Infinix Note 50s 5G takes a clear edge in cameras. Its advantages span both the rear and front systems — higher resolution, a more capable main aperture, and better flash hardware — making it the stronger choice for users who prioritize photography in this comparison.

This is one of the rare categories where the data leaves absolutely nothing to separate the two devices. Both the Infinix Note 50s 5G and the Vivo T4x 5G ship with Android 15 and return an identical result on every single feature tracked in this group — from privacy controls like location, camera, and microphone permissions to productivity staples like split-screen, Picture-in-Picture, and widgets.

Notably, both phones share the same limitations too: neither receives direct OS updates from Google, meaning software patches are routed through the respective manufacturers, which can introduce delays. Neither supports Wi-Fi password sharing or focus modes. These are shared constraints, not differentiators, but worth keeping in mind for users who prioritize timely security updates.

The verdict here is a complete tie. Since every supported and unsupported feature is mirrored across both devices, the operating system experience will be functionally identical out of the box. Any differences a user ultimately perceives will come down to each brand's custom Android skin and its specific UI choices — factors that fall outside the scope of the provided specs.

Battery capacity is where the Vivo T4x 5G makes its most compelling argument in this comparison. Its 6500 mAh cell outpaces the Infinix Note 50s 5G's 5500 mAh by a full 1000 mAh — an 18% larger reservoir that, running on the same chipset, should translate directly into meaningfully longer screen-on time. For heavy users who regularly push through a full day of media consumption, navigation, or social browsing, that gap can be the difference between reaching for a charger in the evening or not.

Charging speed is effectively a wash. The Infinix supports 45W fast charging versus the Vivo's 44W — a 1W difference that produces no real-world distinction in charge times. Both phones ship with a charger included and lack wireless charging, so the overall charging experience is identical in practice.

The Vivo T4x 5G wins this category. Its larger battery is a straightforward endurance advantage, and since neither phone concedes anything meaningful on charging speed, there is no trade-off to weigh against it. It is worth noting, however, that this bigger cell is part of why the Vivo is heavier and thicker — a design cost already captured in the Design group analysis.

Audio is another category where the two phones are mirror images of each other. Both feature stereo speakers and both drop the 3.5mm headphone jack, meaning wired audio requires an adapter or a USB-C alternative on either device. Neither supports any high-resolution Bluetooth audio codec — no aptX, no LDAC, no aptX HD or Adaptive — so wireless listening is capped at standard Bluetooth quality on both.

The absence of advanced codecs like LDAC is the most notable shared limitation for audiophiles, as LDAC in particular can transmit audio at significantly higher bitrates than standard Bluetooth, making a genuine difference with quality wireless headphones. Neither phone offers that capability, which places a ceiling on the wireless audio experience regardless of which one you choose.

This category is a tie — the specs are identical in every dimension tracked. Audio quality in real-world use will depend entirely on speaker tuning and software processing, neither of which is captured in the provided data.

Across most of this spec group, the two phones are closely matched. Both support 5G, dual SIM, Wi-Fi 6, Bluetooth 5.4, USB Type-C, GPS, Galileo, an infrared sensor, gyroscope, accelerometer, and a fingerprint scanner. Cellular download and upload speeds are identical at 3270 Mbits/s. For the vast majority of connectivity use cases — mobile data, wireless networking, Bluetooth accessories, location services — users will experience no meaningful difference between the two.

The one exception that genuinely matters is NFC. The Infinix Note 50s 5G includes it; the Vivo T4x 5G does not. NFC underpins contactless payments, quick Bluetooth pairing with compatible accessories, and transit card functionality in many cities. For users who rely on their phone as a digital wallet — a habit that has become increasingly mainstream — its absence on the Vivo is a concrete daily inconvenience rather than a niche omission.

The Infinix Note 50s 5G takes a clear edge here, and NFC is the sole reason. Everything else in this category is evenly matched, but losing tap-to-pay capability is a meaningful functional gap that will matter to a broad range of users.

This group is light on data points, but one distinction stands out: the Infinix Note 50s 5G features a curved display, while the Vivo T4x 5G uses a flat panel. A curved screen gives the device a more premium, sculpted aesthetic and can make edge-to-edge swiping gestures feel more natural — though it also makes screen protectors slightly harder to fit and can introduce unintended touch inputs at the edges for some users.

Beyond that, both phones share a video light and neither carries sapphire glass or an e-paper display, leaving the curved versus flat panel as the only meaningful differentiator in this category.

The Infinix Note 50s 5G holds a modest edge here for users who value a more refined, flagship-style form factor. That said, the advantage is largely cosmetic and ergonomic — buyers who prefer flat displays for practicality reasons will see the Vivo's design as equally valid, if not preferable.
