Instead of prioritizing design alone, the Y400 Pro combines premium aesthetics with meaningful hardware upgrades and AI-driven features.
At just 7.49mm thick, it is currently the slimmest smartphone with a 3D curved display in its price category. The real question, however, is whether its internal hardware matches the elegance of its exterior. Below is a detailed breakdown.
Design & Build Quality: Premium Look with Practical Strength
Most phones in this segment rely on basic plastic finishes. The Vivo Y400 Pro adopts a refined High-Gloss Matte back panel that feels distinctly premium in hand.
- Freestyle White finish uses a dual-layer coating that creates a pearl-like shimmer, subtly changing with lighting conditions.
- IP65 certification offers better protection than the usual IP54 rating, safeguarding the phone against dust and low-pressure water jets.
- 182g weight ensures comfortable one-handed usage despite the large display.
Display: U8 AMOLED Sets a New Standard
The phone features a 6.77-inch FHD+ 3D Curved AMOLED panel with a 120Hz refresh rate. Beyond the headline specs, several underlying technologies elevate the viewing experience.
- Peak brightness of 4,500 nits ensures excellent outdoor visibility, even in harsh sunlight.
- U8 light-emitting material improves power efficiency by roughly 15% compared to older E-series AMOLED panels used by competitors.
- SGS Eye Care certification enables hardware-level blue light reduction, reducing eye strain during extended usage.
Performance: MediaTek Dimensity 7300 (4nm)
Powering the device is the MediaTek Dimensity 7300, manufactured on a 4nm process.
- The smaller node size results in lower heat generation and better sustained performance compared to older Snapdragon mid-range chipsets.
- The phone includes 8GB LPDDR4X RAM, supported by up to 8GB of virtual RAM, enabling smooth multitasking with more than 25 background apps retained.
Camera Capabilities: Designed for Content Creators
The rear camera uses a 50MP Sony IMX882 sensor with Optical Image Stabilization (OIS), while the front houses a 32MP camera.
Key differentiator: Unlike most mid-range phones, the Vivo Y400 Pro supports 4K video recording on both rear and front cameras, making it especially appealing for vloggers and short-form content creators.
Additional highlights include:
- Aura Light ring LED, which dynamically adjusts color temperature for more natural-looking night portraits.
- AI Erase 2.0, allowing users to remove unwanted objects or people from photos directly within the gallery app using generative AI.
Battery & Charging: Built for Long Sessions
A 5,500mAh battery powers the phone, paired with 90W FlashCharge technology.
- Charges from 0 to 50% in approximately 19 minutes.
- Bypass Charging routes power directly to the motherboard during gaming, reducing device temperature by up to 3°C and helping preserve long-term battery health.
