Nothing Phone (3a) Pro VS Xiaomi Poco X7 Pro

The most consequential difference in this category is ingress protection. The Xiaomi Poco X7 Pro carries an IP68 rating, meaning it is fully waterproof and can withstand submersion in water — a meaningful real-world safeguard against drops in sinks, puddles, or rain. The Nothing Phone (3a) Pro, rated IP64, is only splash and dust resistant; it can handle rain and minor splashes but should never be submerged. For users who want genuine peace of mind around water exposure, this is a clear and practical advantage for the Poco X7 Pro.

On physical form, the Poco X7 Pro is the more compact and lighter device: at 198 g and 8.3 mm thick, it edges out the Nothing Phone (3a) Pro's 211 g and 8.4 mm. The 13-gram weight difference is noticeable over long one-handed sessions or extended use, and the slightly smaller footprint (75.2 × 160.8 mm vs. 77.5 × 163.5 mm) makes it easier to pocket and grip. Neither phone has a rugged build or foldable form factor, so those traits are a wash.

One area where the Nothing Phone (3a) Pro holds a surprising advantage is cold-weather tolerance: its rated minimum operating temperature of -40 °C versus the Poco X7 Pro's 0 °C is a substantial gap that matters for users in very cold climates. Overall, however, the Poco X7 Pro has the edge in this group, driven primarily by its superior IP68 waterproofing and its lighter, more pocketable body.

Both panels are OLED/AMOLED with a 120Hz refresh rate and identical 5,000,000:1 contrast ratios, so the fundamentals are strong on both sides. Where they diverge significantly is sharpness and brightness. The Poco X7 Pro packs a 446 ppi pixel density at a 1220 x 2712 px resolution, compared to the Nothing Phone (3a) Pro's 387 ppi at 1080 x 2392 px — a gap that is genuinely visible when reading fine text or viewing detailed images up close. Combined with a typical brightness of 1400 nits versus 800 nits, the Poco X7 Pro's screen will also remain far more legible under direct sunlight, where the Nothing Phone (3a) Pro may struggle.

The Poco X7 Pro further adds Dolby Vision support and branded damage-resistant glass, neither of which the Nothing Phone (3a) Pro offers. Dolby Vision is the more sophisticated HDR standard with dynamic, frame-by-frame metadata, meaning compatible streaming content will look more accurately graded. The absence of branded glass on the Nothing Phone (3a) Pro is a practical durability concern as well, not just a spec-sheet omission.

The one area where the Nothing Phone (3a) Pro pulls ahead is touch sampling rate: 1000Hz versus 480Hz on the Poco X7 Pro. This matters almost exclusively in fast-paced gaming, where higher polling reduces input latency. For everyday use, the difference is imperceptible. Taking the full picture into account, the Poco X7 Pro holds a clear display advantage, with meaningfully sharper resolution, substantially higher brightness, and broader HDR support.

The raw performance gap here is substantial. The Poco X7 Pro's MediaTek Dimensity 8400 posts an AnTuTu score of 1,663,422 against the Nothing Phone (3a) Pro's Snapdragon 7s Gen 3 score of 750,673 — more than double. Geekbench 6 confirms the same story: the Poco X7 Pro leads in both single-core (1583 vs. 1162) and multi-core (6137 vs. 3239) results. In practice, this translates to snappier app launches, smoother multitasking under load, and a noticeably more capable experience in sustained, CPU-heavy workloads like video editing or high-end gaming.

The memory subsystem difference compounds this advantage. Despite both phones carrying 12GB of RAM, the Poco X7 Pro's memory bandwidth reaches 68.2 GB/s versus just 25.6 GB/s on the Nothing Phone (3a) Pro — a 2.7× gap that means the Dimensity 8400 can feed its CPU and GPU cores far faster, reducing bottlenecks in demanding tasks. The Poco X7 Pro also ships with 512GB of internal storage compared to 256GB, doubling long-term capacity for media and apps.

Shared specs — both use a 4 nm process node, 8-thread big.LITTLE CPU layouts, DDR5 memory, and DirectX 12 support — mean the architectural foundations are modern on both devices. But the execution is in a different league. The Poco X7 Pro has an unambiguous and sizeable performance advantage in this category across every meaningful benchmark metric.

Camera system versatility splits sharply between these two. The Nothing Phone (3a) Pro fields a triple rear camera setup including a dedicated 50MP telephoto lens with 3x optical zoom, a capability the Poco X7 Pro entirely lacks — its rear system is dual-lens with 0x optical zoom. For anyone who regularly shoots at distance, portraits with subject separation, or street photography, this is a meaningful real-world advantage for the Nothing Phone (3a) Pro. Its primary lens also opens wider at f/1.9 versus the Poco's f/2.2, admitting more light in low-light conditions.

The Poco X7 Pro punches back on video and autofocus. It captures 4K footage at 60 fps compared to the Nothing Phone (3a) Pro's cap of 30 fps — a significant difference for smooth motion video, action recording, or content creators who want more flexibility in post-production. It also adds laser autofocus and HDR10 video recording, neither of which the Nothing Phone (3a) Pro supports, giving it an edge in fast-focus accuracy and dynamic range preservation in recorded video.

For selfies, the Nothing Phone (3a) Pro's 50MP front camera dwarfs the Poco X7 Pro's 20MP sensor, a gap that translates to more detail and greater cropping flexibility. Both phones share OIS, phase-detection autofocus, RAW shooting, and slow-motion support, keeping the foundation competitive. Overall this is a trade-off rather than a clean sweep: the Nothing Phone (3a) Pro is the stronger choice for zoom photography and selfies, while the Poco X7 Pro has the edge in video quality and autofocus speed.

Across every single data point in this specification group, the Nothing Phone (3a) Pro and the Xiaomi Poco X7 Pro are identical. Both ship with Android 15, share the same privacy feature set — including location controls, camera and microphone permissions, and app tracking blocking — and offer the same suite of usability features such as split-screen, Picture-in-Picture, dynamic theming, dark mode, and offline voice recognition.

This is a complete tie by the provided data. Neither phone receives direct OS updates, neither supports Wi-Fi password sharing or focus modes, and both equally lack Mail Privacy Protection and cross-site tracking blocking. There is no differentiator to analyze here, meaningful or minor — the spec sheets are a mirror image of each other for this category.

The Poco X7 Pro holds a clear advantage on both ends of the battery equation. Its 6000 mAh cell is 20% larger than the Nothing Phone (3a) Pro's 5000 mAh, which directly translates to longer time between charges — a difference that heavy users, travelers, or anyone away from an outlet for extended periods will feel tangibly across a full day of use.

Charging speed widens the gap further. At 90W, the Poco X7 Pro replenishes its larger battery considerably faster than the Nothing Phone (3a) Pro's 50W — meaning shorter top-up windows despite having more capacity to fill. The Poco X7 Pro also ships with a charger included in the box, while the Nothing Phone (3a) Pro does not, adding an immediate out-of-pocket consideration for new buyers who don't already own a compatible fast charger.

Neither phone supports wireless charging or has a removable battery, so those factors cancel out. On every meaningful metric in this category — capacity, charging speed, and in-box value — the Poco X7 Pro is the stronger option by a comfortable margin.

For wireless audio enthusiasts, the Poco X7 Pro has a meaningful edge. It supports both LDAC and aptX HD — high-resolution Bluetooth codecs that transmit significantly more audio data than standard SBC or AAC, delivering noticeably better sound quality when paired with compatible headphones. The Nothing Phone (3a) Pro supports none of these codecs, meaning wireless listening is limited to lower-fidelity transmission regardless of how capable the connected headphones are.

Speaker and wired output configurations are largely matched: both phones drop the 3.5mm headphone jack and feature stereo speakers, so speakerphone and media playback through the built-in drivers are on equal footing. Where the Nothing Phone (3a) Pro quietly reclaims some ground is microphone count — 3 microphones versus the Poco X7 Pro's 2, which can improve noise cancellation during calls and voice recording by providing an additional reference point for background sound isolation.

The trade-off is clear but uneven in weight: better wireless audio codec support on the Poco X7 Pro is a persistent, everyday advantage for anyone using Bluetooth headphones, while the extra microphone on the Nothing Phone (3a) Pro is a narrower benefit. For wireless listening quality, the Poco X7 Pro takes this category.

Cellular performance is where the gap opens most visibly. The Poco X7 Pro supports download speeds of up to 5700 Mbits/s compared to the Nothing Phone (3a) Pro's 2900 Mbits/s — nearly double — meaning the Poco X7 Pro is better positioned to take advantage of fast 5G networks for large file transfers, streaming, and latency-sensitive tasks. Its Bluetooth 6 also edges ahead of the Nothing Phone (3a) Pro's Bluetooth 5.4, bringing improved connection stability, more precise proximity-based features, and better energy efficiency with compatible devices.

The Poco X7 Pro also includes an infrared sensor, which allows it to function as a universal remote for TVs and home appliances — a niche but genuinely useful convenience that the Nothing Phone (3a) Pro lacks entirely. Everything else in this category is shared: both offer 5G, dual SIM, Wi-Fi 6, NFC, USB Type-C with USB 2.0, GPS with Galileo support, and the same core sensor suite including gyroscope, accelerometer, and compass.

Neither phone supports external memory expansion, satellite SOS, or crash detection, keeping those factors level. But taken together, the Poco X7 Pro's faster modem, newer Bluetooth, and added infrared blaster give it a modest but genuine edge in connectivity and utility for this group.

This specification group offers nothing to differentiate the two devices. The Nothing Phone (3a) Pro and the Xiaomi Poco X7 Pro share identical traits across every data point provided: both have a video light, and neither features sapphire glass, a curved display, or an e-paper display. This is a complete tie, and no advantage can be assigned to either product based solely on the available data.
