Vivo has consistently improved its design language, and the Y400 Pro 5G represents another step forward. The device features a sleek, premium-feeling body with a thickness of just 7.4mm and weighing approximately 185 grams. This makes it comfortable for extended use while maintaining a substantial feel in hand.
The front of the device is dominated by a 6.7-inch display with minimal bezels and a tiny punch-hole camera. The back panel showcases a nano-textured finish that resists fingerprints while creating an attractive light-catching pattern. Available in Cosmic Black, Ocean Blue, and Sunrise Gold, the color options offer something for every preference.
The frame is constructed from a high-grade aluminum alloy, providing structural rigidity without adding excessive weight. Vivo has also implemented IP68 water and dust resistance, marking a welcome addition to the Y-series that previously lacked comprehensive protection against the elements.
Physical buttons are positioned along the right edge, with a slightly textured power button doubling as a fingerprint scanner. The bottom edge houses a USB-C port, speaker grille, and SIM tray, while the top edge includes an IR blaster – a feature appreciated by many users for controlling home appliances.
Vivo Y400 Pro 5G Display Technology
The Y400 Pro 5G features a 6.7-inch AMOLED display with a resolution of 2400 x 1080 pixels (FHD+). The panel supports a 120Hz refresh rate with adaptive switching between 60Hz, 90Hz, and 120Hz depending on content, helping to balance smoothness and battery efficiency.
Particularly impressive is the peak brightness, which reaches 1,300 nits for HDR content and 900 nits for typical outdoor use. This represents a significant improvement over previous Y-series models and ensures excellent visibility even under direct sunlight.
Color reproduction is a highlight, with the display covering 100% of the DCI-P3 color gamut and offering accurate calibration out of the box. Vivo provides several color profiles, allowing users to choose between vivid colors or more natural tones according to their preference.
The display is protected by Corning Gorilla Glass Victus 2, providing enhanced drop and scratch resistance. The in-display fingerprint scanner is responsive and accurate, utilizing the latest ultrasonic technology rather than the older optical sensors found in previous models.
Vivo Y400 Pro 5G Performance and Hardware
Powering the Y400 Pro 5G is the Mediatek Dimensity 8300 chipset, manufactured on a 4nm process. This octa-core processor features four Cortex-A715 performance cores clocked at 3.0GHz and four Cortex-A510 efficiency cores running at 2.0GHz, delivering excellent performance while maintaining power efficiency.
The Mali-G615 GPU handles graphics duties capably, providing smooth gameplay for popular titles like PUBG Mobile, Call of Duty Mobile, and Genshin Impact at medium to high settings. Vivo has implemented a vapor chamber cooling system that helps maintain performance during extended gaming sessions by effectively dissipating heat.
Memory configurations include 8GB/128GB, 8GB/256GB, and 12GB/256GB variants. Vivo uses LPDDR5X RAM and UFS 3.1 storage across all models, ensuring snappy multitasking and quick app launches. The RAM can be virtually extended by up to 8GB using unused storage space, though the benefit of this feature remains debatable among power users.
Network connectivity is comprehensive, with support for all major 5G bands in respective regions, Wi-Fi 6E, Bluetooth 5.3, and NFC. The dual-frequency GPS ensures accurate location tracking even in challenging urban environments.
Vivo Y400 Pro 5G Camera System
The camera system represents one of the most significant upgrades over previous Y-series models. The primary camera features a 50MP Sony IMX882 sensor with optical image stabilization, an f/1.8 aperture, and Vivo’s latest image processing algorithms.
Supporting this main shooter is a 13MP ultrawide camera with a 120-degree field of view and a 2MP macro camera for close-up shots. The front-facing camera is a 32MP unit capable of 4K video recording, making it suitable for high-quality video calls and social media content creation.
Image quality from the main camera impresses in various lighting conditions, with natural colors, good dynamic range, and well-controlled noise levels. Night mode has seen substantial improvements, capturing detailed low-light scenes with minimal blur and noise. Portrait mode benefits from accurate edge detection and natural-looking background blur.
Video capabilities include 4K recording at 60fps from the main camera, with effective electronic image stabilization complementing the optical system for smooth footage. Vivo’s suite of camera features includes dual-view video, various filters, and AI-enhanced scene recognition that optimizes settings based on what you’re shooting.
Vivo Y400 Pro 5G Software Experience
The Y400 Pro 5G runs Funtouch OS 15, based on Android 15. Vivo has promised three years of major Android updates and four years of security patches, demonstrating a commitment to long-term software support.
Funtouch OS has matured significantly, striking a better balance between features and simplicity. The interface is clean and customizable, with numerous themes, icon packs, and always-on display options. Bloatware has been reduced compared to earlier versions, though some pre-installed apps remain.
Vivo’s AI features are integrated throughout the system, offering smart recommendations, automatic text recognition from images, and contextual awareness that adapts phone behavior based on usage patterns. Privacy features have been enhanced, with granular permission controls and a privacy dashboard that provides clear visibility into how apps access your data.
Multitasking is well-implemented, with split-screen functionality, floating windows, and app pairs that launch two apps simultaneously. The system remains fluid even with multiple apps running, thanks to efficient memory management.
Vivo Y400 Pro 5G Battery Life and Charging
Battery life is a standout feature of the Y400 Pro 5G, with its 5,000mAh cell easily lasting through a full day of heavy use. More moderate users can expect up to two days between charges, representing excellent endurance for a mid-range device.
Charging technology includes 80W wired fast charging that can replenish the battery from empty to 60% in approximately 20 minutes, with a full charge taking around 45 minutes. The phone also supports 30W wireless charging, though the wireless charger is sold separately.
Battery health features include charge limiting options that can stop charging at 80% to extend long-term battery lifespan, as well as optimized night charging that slows down the final charging phase to reduce battery stress.
Vivo Y400 Pro 5G Audio Experience
The stereo speaker setup delivers balanced, clear audio with good volume levels. While bass response is predictably limited by the small speaker size, the overall sound quality is impressive for a mid-range device. The inclusion of Dolby Atmos support enhances the audio experience when using headphones.
Vivo has retained the 3.5mm headphone jack, a feature increasingly rare in the market but appreciated by many users who prefer wired audio solutions. Hi-Res audio certification ensures quality sound for those using compatible wired headphones.
Vivo Y400 Pro 5G Market Positioning and Value
Positioned in the competitive mid-range segment, the Y400 Pro 5G offers excellent value for its price point. It competes directly with devices like the Realme GT Neo 5, Xiaomi Redmi Note 13 Pro+, and Samsung Galaxy A55 5G.
What sets the Y400 Pro 5G apart is its balanced approach, with no obvious weaknesses across key areas like display quality, camera performance, battery life, and processing power. While some competitors might edge ahead in specific aspects, the Vivo offers perhaps the most well-rounded experience in its price category.
Vivo Y400 Pro 5G
The Vivo Y400 Pro 5G represents a compelling option for consumers seeking a capable smartphone without venturing into flagship price territory. Its combination of premium design elements, capable camera system, excellent battery life, and solid performance makes it easy to recommend.
As smartphone technology continues to mature, the differences between mid-range and flagship devices become increasingly subtle. The Y400 Pro 5G exemplifies this trend, delivering a user experience that would have been considered flagship-level just a few years ago.
