Nothing Phone (3a) VS Xiaomi Redmi Turbo 4 Pro

In terms of physical footprint, these two phones are remarkably close. Both share nearly identical height and width — around 163 mm tall and 77–78 mm wide — placing them in the same large-screen ergonomic category. Where they diverge slightly is in thickness and weight: the Nothing Phone (3a) is marginally thicker at 8.4 mm versus the Redmi Turbo 4 Pro's 8 mm, while the Redmi is notably heavier at 219 g compared to the Nothing's 201 g. That 18-gram difference is perceptible in daily one-handed use — the Nothing Phone (3a) will feel meaningfully lighter over long sessions.

The most consequential design difference, however, is water protection. The Nothing Phone (3a) carries an IP64 rating, meaning it can resist water splashes and jets but is not submersion-proof. The Redmi Turbo 4 Pro steps up to IP68, which certifies full immersion protection — typically up to 1.5 meters for 30 minutes. In real-world terms, IP68 means peace of mind around pools, rain, or accidental drops in water, whereas IP64 covers everyday splashes but little more. This is a meaningful gap for users who want genuine waterproofing rather than just water resistance.

Overall, the Redmi Turbo 4 Pro holds a clear edge in water protection, which is arguably the most practically important design spec for durability. The Nothing Phone (3a) counters with a lighter build and a slightly slimmer volume, making it the more comfortable daily carry. Neither device offers a rugged build or folding form factor, so the choice within this group comes down to priorities: submersion-level waterproofing favors the Redmi, while lightweight comfort favors the Nothing.

Both phones use OLED/AMOLED panels and share a 120Hz refresh rate, so the baseline viewing experience — deep blacks, vivid colors, smooth scrolling — is comparable. The screen sizes are also very close, at 6.77″ for the Nothing Phone (3a) versus 6.83″ for the Redmi Turbo 4 Pro, a difference that is essentially invisible in everyday use. Where things start to diverge significantly is in resolution and pixel density: the Redmi pushes a 1280 x 2772 px panel at 447 ppi, versus the Nothing's 1080 x 2392 px at 387 ppi. That 60-ppi gap is noticeable — text and fine details appear measurably crisper on the Redmi, particularly when reading small print or viewing high-resolution images up close.

The brightness disparity is arguably the most impactful real-world difference here. The Nothing Phone (3a) is rated at 800 nits typical brightness, while the Redmi Turbo 4 Pro more than doubles that at 1800 nits. In direct sunlight, the Redmi will remain far more legible — a practical advantage for outdoor users. The Redmi also adds Dolby Vision support on top of the shared HDR10 and HDR10+ certifications, which expands the range of streaming content that can render at its intended quality on platforms like Netflix and Apple TV+. The Nothing Phone (3a) misses out on Dolby Vision entirely.

The Redmi's 2560Hz touch sampling rate versus the Nothing's 240Hz is a spec worth contextualizing: in gaming scenarios requiring ultra-precise, rapid inputs, the higher sampling rate can reduce latency, though for general use the difference is imperceptible. Taken together, the Redmi Turbo 4 Pro holds a commanding display advantage — superior sharpness, dramatically higher brightness, and broader HDR format support make it the stronger panel in nearly every measurable dimension.

The chipset gap here is not subtle. The Nothing Phone (3a) runs on the Snapdragon 7s Gen 3, a capable mid-range silicon, while the Redmi Turbo 4 Pro is powered by the Snapdragon 8s Gen 4 — a chip from an entirely different performance tier. The benchmark numbers confirm this decisively: the Redmi scores 2,406,698 on AnTuTu versus the Nothing's 816,384, nearly a 3x difference. In Geekbench 6, the Redmi's single-core score of 2154 outpaces the Nothing's 1162 by nearly double, and the multi-core gap is even wider at 6880 vs 3239. These are not marginal gains — they translate to meaningfully faster app launches, smoother multitasking under load, and a substantially better experience in demanding games or video editing workflows.

Memory architecture reinforces the performance story. The Redmi ships with 16GB of RAM at 4800 MHz and a maximum memory bandwidth of 76.8 GB/s, compared to the Nothing's 12GB at 3200 MHz with just 25.6 GB/s bandwidth. Higher bandwidth means data moves between the CPU, GPU, and RAM far more rapidly — critical for tasks like gaming, camera processing, and running multiple apps simultaneously without slowdown. The Redmi's 1TB of internal storage also dwarfs the Nothing's 256GB, a practical consideration for users who store large media libraries locally.

The Redmi's higher 12.5W TDP versus the Nothing's 5W signals that the more powerful chip runs hotter and draws more power under sustained load — a trade-off inherent to flagship-tier performance. For the Nothing Phone (3a), the lower TDP suggests better thermal efficiency and potentially more consistent sustained performance in extended sessions. That said, the Redmi Turbo 4 Pro wins the performance category comprehensively, and by a wide margin across every key metric — raw compute, memory throughput, and storage capacity.

Rear camera versatility tips clearly in favor of the Nothing Phone (3a). It fields a triple-camera system — two 50MP sensors and an 8MP unit — versus the Redmi Turbo 4 Pro's dual-camera setup of 50MP and 8MP. Crucially, the Nothing includes 2x optical zoom while the Redmi lists 0x optical zoom, meaning the Redmi relies entirely on digital crop for any telephoto framing. Optical zoom preserves genuine detail; digital zoom does not. For users who regularly shoot portraits or distant subjects, this is a tangible real-world gap. The Nothing's primary sensor also carries a wider aperture of f/1.9 compared to the Redmi's main lens at f/2.2 — a wider aperture gathers more light, which generally benefits low-light photography.

Video recording is where the Redmi punches back. It captures 4K footage at 60fps, versus the Nothing's cap of 4K at 30fps. That doubled frame rate produces noticeably smoother motion in fast-action scenes and provides more flexibility in post-production for slow-motion effects at full resolution. The Redmi also packs 3 flash LEDs against the Nothing's single LED, which can mean more even and powerful illumination for flash photography. On the selfie side, the Nothing counters with a 32MP front camera compared to the Redmi's 20MP, an advantage for users who prioritize selfie detail or video calls.

This category does not have a clean winner — the two phones make different trade-offs. The Nothing Phone (3a) holds the edge for photo versatility, offering optical zoom, a wider-aperture main sensor, and a higher-resolution front camera. The Redmi Turbo 4 Pro is the stronger video device, with smoother 4K@60fps capture and a more powerful flash array. The right choice here depends directly on whether stills or video is the higher priority.

Across every single data point in this category, the Nothing Phone (3a) and Xiaomi Redmi Turbo 4 Pro are in complete lockstep. Both ship with Android 15 and share an identical feature set — from privacy controls like location and camera/microphone permissions, to usability staples like split-screen multitasking, Picture-in-Picture, dynamic theming, and on-device machine learning. There is not a single differentiating spec in this group.

This is largely a consequence of both phones running the same underlying OS version. The privacy toolkit — clipboard warnings, app tracking controls, granular notification permissions — reflects Android 15's platform-level capabilities rather than anything either manufacturer has uniquely added or removed. Neither device gets direct OS updates, meaning both will depend on their respective manufacturers for Android version upgrades, a consideration that sits outside the provided data but is worth keeping in mind when evaluating long-term software support.

The verdict here is a complete tie. Based strictly on the provided specifications, no advantage exists for either product in this category. Users choosing between these two phones should look to the other specification groups — performance, display, cameras, and design — to inform their decision, as operating system features offer zero differentiation between them.

Battery capacity is where the Redmi Turbo 4 Pro makes one of its most striking statements. Its 7550 mAh cell is 51% larger than the Nothing Phone (3a)'s 5000 mAh — a difference that, in practice, can translate to an entire additional day of use for moderate users. While 5000 mAh is a perfectly respectable capacity for a mid-range phone in 2025, the Redmi's pack pushes well into power-user territory, making it a compelling option for heavy users, frequent travelers, or anyone who dreads hunting for an outlet.

Charging speed compounds the Redmi's advantage further. At 90W, it charges nearly twice as fast as the Nothing's 50W — and it does so from a significantly larger starting pool. Faster charging on a bigger battery means the Redmi can recover from low charge levels rapidly, reducing the penalty of its higher capacity. The Redmi also includes a charger in the box, while the Nothing Phone (3a) does not — a meaningful out-of-box difference that adds to the total cost of ownership for Nothing buyers who need one. Neither phone supports wireless charging, so both are limited to wired top-ups.

The Redmi Turbo 4 Pro wins this category decisively on every metric: more capacity, faster charging, and a bundled charger. The Nothing Phone (3a) offers nothing to offset these gaps within the battery spec group. For users who prioritize endurance above all else, the Redmi's battery setup is a compelling differentiator in its own right.

For the most part, audio hardware on these two phones is identical on paper: both drop the 3.5mm headphone jack, both feature stereo speakers, and neither supports LDAC, aptX HD, aptX Adaptive, or a radio tuner. The one differentiator is that the Redmi Turbo 4 Pro includes aptX Bluetooth codec support, which the Nothing Phone (3a) lacks entirely.

aptX matters specifically for wireless audio over Bluetooth headphones or earbuds that also support the codec. Where standard SBC compression can introduce audible artifacts, aptX reduces latency and preserves more audio detail — a genuine improvement for music listening and video watching through compatible wireless headphones. That said, the benefit is only realized if the paired headphones also support aptX; users with standard earbuds or LDAC-only devices will notice no difference at all.

This is a narrow category with limited data to work with. The Redmi Turbo 4 Pro holds a slim edge thanks to aptX support, which is a meaningful perk for wireless audio enthusiasts with the right gear. For everyone else, the two phones are functionally equivalent in audio output capability based on the provided specs, and neither stands out as a particularly audio-focused device.

Shared foundations are strong across both devices — 5G, Bluetooth 5.4, NFC, dual SIM, USB-C, fingerprint scanner, and a solid sensor suite including GPS, gyroscope, and accelerometer. For the vast majority of connectivity use cases, these two phones are interchangeable. The meaningful gaps, however, are worth unpacking carefully.

The most consequential difference is Wi-Fi generation. The Nothing Phone (3a) tops out at Wi-Fi 6 (802.11ax), while the Redmi Turbo 4 Pro extends to Wi-Fi 7 (802.11be). Wi-Fi 7 delivers substantially higher throughput and lower latency on compatible routers — the peak download speed figures reflect this directly: 4200 Mbps for the Redmi versus 2900 Mbps for the Nothing. In practice, most users will not saturate Wi-Fi 6 speeds today, but Wi-Fi 7 represents better future-proofing as router infrastructure upgrades over the life of the device. The Redmi also includes an infrared sensor, which the Nothing omits entirely — a niche but genuinely useful feature that turns the phone into a universal remote for TVs, air conditioners, and other IR-controlled appliances without needing a separate app or device.

The Redmi Turbo 4 Pro takes a clear edge in connectivity, driven by Wi-Fi 7 support, higher peak wireless speeds, and the added utility of an infrared blaster. The Nothing Phone (3a) covers all essential connectivity bases competently, but offers nothing to distinguish itself within this category.

The miscellaneous category offers very little to analyze here — the provided specs are few, and both phones match on every single one. Both feature a video light, and neither has a sapphire glass display, a curved display, or an e-paper display. There is no differentiating data point in this group whatsoever.

This is an unambiguous tie. Users should weigh the other specification groups — particularly performance, display, battery, and design — when making their final decision, as this category contributes nothing to distinguish one phone from the other.
