Vivo Y400 Specifications
The Vivo Y400 5G was announced on August 4, 2025 and released shortly after on August 7. It comes with a 6.67-inch AMOLED display that feels premium for the segment. The screen offers Full HD+ resolution (1080×2400 pixels) with a sharp ~395 ppi density, making text and videos look crisp. The 120Hz refresh rate keeps scrolling smooth, while 1200 nits HBM and 1800 nits peak brightness ensure good outdoor visibility. The phone has a slim 7.9mm body, weighs 197g, and uses a glass front with a plastic back and frame. Despite the materials, it stands out with IP68/IP69 water and dust resistance and MIL-STD-810H compliance, which is rare at this price. Colors include Glam White and Olive Green, both looking clean and modern.
In daily use, the Vivo Y400 5G feels reliable and smooth. It runs on Android 15 with Funtouch OS 15, which is feature-rich and easy to use. Performance is handled by the Snapdragon 4 Gen 2 (4nm) chipset, paired with Adreno 613 GPU, making it suitable for normal gaming, multitasking, and long-term efficiency. Storage options include 128GB or 256GB with 8GB RAM, using fast UFS 3.1 storage. The camera setup focuses on simplicity. The 50MP main camera with PDAF captures good daylight photos with natural colors, while the auxiliary lens is basic. Video recording is limited to 1080p at 30fps. On the front, the 32MP selfie camera is a strong point, delivering sharp selfies and clear video calls. Stereo speakers with Hi-Res audio add to the media experience, though there is no headphone jack.
Battery life is one of the biggest highlights. The phone packs a large 6000mAh battery, easily lasting more than a day of heavy use. The 90W fast charging is impressive, reaching 50% in just 20 minutes, and features like reverse wired charging and bypass charging are useful extras. Connectivity includes 5G support, Wi-Fi ac, Bluetooth 5.0, and an in-display fingerprint sensor. Priced at $255 (Rs 22,999 in India), the Vivo Y400 5G offers a strong mix of display quality, durability, battery, and fast charging. The 4G variant, launched earlier in July 2025, looks similar but uses a Snapdragon 685, slower UFS 2.2 storage, a weaker 8MP selfie camera, and 44W charging, making the 5G version the better and more future-ready choice overall.
