Vivo S30 VS Xiaomi Redmi Turbo 4 Pro

In terms of physical footprint, the Vivo S30 is the noticeably more compact and lighter device. At 192 g and 7.5 mm thick, it undercuts the Redmi Turbo 4 Pro's 219 g and 8 mm profile by meaningful margins — a 27 g weight difference is something most users will feel during prolonged one-handed use or when carrying the phone in a pocket all day. The smaller overall volume (89.4 cm³ vs 101.6 cm³) reinforces that the S30 is the more pocketable, ergonomically friendlier choice of the two.

On water resistance, the two phones share the same ″Waterproof″ classification but differ in certified protection level: the Redmi Turbo 4 Pro carries an IP68 rating, while the Vivo S30 is rated IP67. In practical terms, IP67 covers submersion up to 1 meter for 30 minutes, whereas IP68 is tested at greater depth and/or duration as declared by the manufacturer. For most everyday scenarios — rain, splashes, accidental drops in shallow water — both ratings offer reliable protection. The IP68 edge on the Redmi only becomes relevant in less common, more extreme water exposure situations.

Neither phone offers a rugged build or a foldable form factor, so those factors are a wash. Overall, the design comparison comes down to a genuine trade-off: the Vivo S30 has a clear advantage in portability and handling comfort, while the Redmi Turbo 4 Pro holds the edge in water resistance certification. Users who prioritize a slimmer, lighter device will favor the S30; those who want the extra peace of mind from a higher IP rating may lean toward the Redmi.

Both phones use OLED/AMOLED panels with a 120Hz refresh rate, so the baseline display experience — deep blacks, vibrant colors, and smooth scrolling — is shared across the board. Where they start to diverge is in size and sharpness: the Redmi Turbo 4 Pro's 6.83″ screen is slightly larger, but the Vivo S30's 6.67″ panel actually resolves more pixels per inch (460 ppi vs 447 ppi), meaning text and fine detail will appear fractionally crisper on the S30 despite its smaller canvas. In everyday use, the difference is subtle, but it's worth noting for users who read extensively on their phone.

The more consequential gap is in brightness and HDR support. The Redmi's 1800 nits typical brightness gives it a significant edge in outdoor legibility under direct sunlight compared to the S30's 1300 nits — a 500-nit difference is perceptible in real-world conditions, not just on paper. Beyond raw brightness, the Redmi also supports HDR10, HDR10+, and Dolby Vision, meaning streaming content from platforms like Netflix or Amazon Prime will render with wider dynamic range and more accurate tone-mapping when the source material supports it. The Vivo S30 lacks all three HDR standards, which is a notable omission for media-focused users.

The S30 does counter with one meaningful advantage: branded damage-resistant glass, which the Redmi does not carry — adding a layer of real-world durability reassurance for users who skip screen protectors. Both panels include Always-On Display. Taken as a whole, the Redmi Turbo 4 Pro holds a clear display edge for anyone who prioritizes media consumption and outdoor use, while the Vivo S30 appeals more to users who value pixel sharpness and screen protection.

The chipset gap here is the defining story of this comparison. The Vivo S30 runs on the Snapdragon 7 Gen 4, a capable upper-mid-range processor, while the Redmi Turbo 4 Pro steps up to the Snapdragon 8s Gen 4 — a chip that sits a full tier above in Qualcomm's lineup. This difference cascades across nearly every performance metric: the Redmi's CPU peaks at 3.21 GHz versus the S30's 2.8 GHz top core, its GPU runs at 1150 MHz versus 1000 MHz, and its RAM operates at 4800 MHz versus 4200 MHz. For everyday tasks these distinctions are marginal, but in sustained workloads — intensive gaming, video editing, or heavy multitasking — the Redmi's silicon headroom will be noticeably more capable.

The memory bandwidth figure is particularly telling: the Redmi Turbo 4 Pro's 76.8 GB/s versus the S30's 33.6 GB/s is more than a double advantage, meaning the Redmi can feed its CPU and GPU with data far faster. This translates directly into smoother frame rates under load and quicker large-file operations. Both phones share 16 GB of RAM, so app multitasking capacity is equal, but the Redmi's faster memory subsystem means it uses that RAM more efficiently. Storage is also a straightforward win for the Redmi, which offers up to 1024 GB compared to the S30's 512 GB ceiling — a meaningful difference for users who store large media libraries locally.

The one counterpoint worth flagging is thermal output: the Redmi's 12.5W TDP versus the S30's 6W TDP indicates the more powerful chip runs hotter and draws more power under sustained load, which can affect both battery life during intensive sessions and long-term thermal comfort in the hand. Still, on raw performance and storage, the Redmi Turbo 4 Pro holds a decisive advantage — it is the clear choice for users who push their device hard.

The rear camera systems take meaningfully different approaches. The Vivo S30 fields a triple-lens setup (50 + 50 + 8 MP) with 3x optical zoom, giving it genuine versatility across shooting distances — from wide scenes to mid-range telephoto, all without degrading to digital interpolation. The Redmi Turbo 4 Pro, by contrast, carries only a dual-lens system (50 + 8 MP) and lists 0x optical zoom, meaning any zoom beyond the standard focal length relies entirely on cropping. For users who frequently shoot subjects at a distance, this is a practical limitation that no software processing can fully compensate for.

Where the Redmi counters effectively is in two areas: light intake and video capability. Its primary lens opens to f/1.5 — notably wider than the S30's f/1.9 main aperture — which allows more light to hit the sensor in dim environments, a genuine low-light photography advantage. On the video side, the Redmi records 4K at 60 fps versus the S30's cap of 30 fps at the same resolution. That doubled frame rate produces smoother footage and more flexibility in post-production for slow-motion edits at full 4K quality. Both phones support OIS, continuous autofocus during recording, and phase-detection autofocus for stills, so stabilization and focus tracking are evenly matched.

Selfie shooters will find a stark contrast: the S30's 50 MP front camera dwarfs the Redmi's 20 MP unit, offering significantly more detail for portraits and a wider cropping margin. On balance, neither phone dominates outright — the Vivo S30 has the edge in versatility and selfie quality thanks to its third lens, optical zoom, and high-resolution front camera, while the Redmi Turbo 4 Pro is the stronger choice for low-light stills and smooth video recording. The right pick depends squarely on which of those use cases matters more to the user.

This is a rare case of a complete spec-for-spec tie. Both the Vivo S30 and the Redmi Turbo 4 Pro launch on Android 15 and share an identical feature set across every tracked operating system attribute — from privacy controls to productivity tools to accessibility options. There is no differentiator to speak of within the provided data.

What that shared foundation does deliver is worth acknowledging. Both phones arrive with a modern, well-rounded software experience: on-device machine learning, dynamic theming, split-screen multitasking, Picture-in-Picture, customizable notifications, and offline voice recognition are all present. On the privacy front, both offer camera and microphone permission controls, location privacy options, and app tracking blocking — a solid baseline for users who care about data hygiene. Neither phone receives direct OS updates, meaning both rely on their respective manufacturer pipelines for Android patches and upgrades.

Since every data point in this group is identical, the operating system category is a complete draw. Users should look to other specification groups — performance, cameras, or design — to differentiate these two devices, as software alone offers no basis for preference here.

Charging speed is the one area where these two phones are perfectly matched — both top out at 90W wired fast charging and ship with a charger included. Neither supports wireless charging, so that potential differentiator is off the table entirely. Where the comparison gets interesting is in raw capacity: the Redmi Turbo 4 Pro packs a 7550 mAh battery against the Vivo S30's already generous 6500 mAh — a 1050 mAh gap that represents over 16% more stored energy.

In practical terms, a 1050 mAh advantage at this capacity tier is meaningful. Assuming comparable efficiency, the Redmi should deliver a noticeably longer time between charges — potentially the difference between comfortably lasting a full day under heavy use versus needing a top-up by evening. That said, the Redmi's more power-hungry Snapdragon 8s Gen 4 chipset (as seen in the Performance group) partially offsets this raw capacity lead, while the S30's lower-TDP chip squeezes more runtime per mAh. The net endurance gap in real use is therefore likely smaller than the cell size difference alone implies.

Still, on the data provided here, the Redmi Turbo 4 Pro holds a clear battery capacity advantage. With identical charging infrastructure on both sides, the Redmi simply has more energy to draw from — making it the stronger choice for users who prioritize all-day or multi-day endurance without reaching for a cable.

Shared ground first: both phones ditch the 3.5mm headphone jack, feature stereo speakers, and lack radio — so wired analog audio and over-the-air FM are equally absent from both devices. For wireless listening, however, the two diverge in a way that genuinely matters to audio enthusiasts. The Vivo S30 supports aptX HD and aptX Adaptive in addition to standard aptX, while the Redmi Turbo 4 Pro stops at aptX alone.

The practical significance of this gap depends on the user's headphone setup. Standard aptX already improves on basic Bluetooth audio, but aptX HD adds higher-bitrate transmission for noticeably improved dynamic range and detail with compatible headphones. aptX Adaptive goes further still — it adjusts bitrate dynamically in real time, delivering both low latency (important for gaming and video sync) and high-quality audio simultaneously. Users pairing either phone with aptX Adaptive-compatible headphones will hear a tangible difference on the S30 that the Redmi simply cannot replicate. Neither phone supports LDAC, so Sony-ecosystem wireless audio users are equally limited on both sides.

The Vivo S30 holds a clear audio advantage in this category. Its broader Bluetooth codec support — particularly aptX Adaptive — makes it the more capable device for wireless audio quality and low-latency use cases, provided the user's headphones support those codecs. For casual listeners relying on basic Bluetooth or the built-in speakers, the gap between the two phones narrows considerably.

Across the bulk of this category, the two phones are functionally identical: both offer 5G, Bluetooth 5.4, NFC, USB Type-C, dual SIM, GPS with Galileo support, an infrared sensor, and the same core sensor suite. The single but noteworthy differentiator is Wi-Fi: the Redmi Turbo 4 Pro adds Wi-Fi 7 (802.11be) to the stack, while the Vivo S30 tops out at Wi-Fi 6 (802.11ax).

Wi-Fi 7 is the latest generation of the standard and delivers substantially higher theoretical throughput, lower latency, and better performance in congested environments — such as apartments with many competing networks — compared to Wi-Fi 6. In practical terms, users with a Wi-Fi 7 router at home or in the office will benefit from faster local transfers and more stable connections on the Redmi. For everyone still on Wi-Fi 6 or older infrastructure, the advantage is dormant for now but becomes increasingly relevant as Wi-Fi 7 routers grow in adoption. It is worth noting that both phones share the same USB 2.0 speed cap, so wired data transfers are equally limited on both devices.

Given how closely matched every other connectivity and sensor specification is, the Redmi Turbo 4 Pro edges ahead in this category solely on the strength of Wi-Fi 7. It is a forward-looking advantage rather than an immediate game-changer for most users today, but for anyone investing in or already running Wi-Fi 7 infrastructure, it is a meaningful differentiator the Vivo S30 cannot match.

The Miscellaneous group offers no basis for differentiation whatsoever. Every tracked attribute — video light presence, sapphire glass, curved display, and e-paper display — returns the exact same value for both the Vivo S30 and the Redmi Turbo 4 Pro. This is a complete tie, and no conclusion can be drawn in favor of either device from this data alone.

The shared presence of a video light is mildly worth noting for users who shoot video in low-light conditions, as it provides continuous illumination beyond a standard photo flash. The absence of a curved display on both phones means users who prefer flat, edge-to-edge glass — which tends to reduce accidental touch inputs and is generally easier to protect with a screen protector — will find both devices equally accommodating on that front.
