The Vivo X300 Ultra 5G showcases a design philosophy that blends aesthetic appeal with functional ergonomics. The device features a sleek aluminum frame sandwiched between glass panels, with the rear utilizing a nano-textured matte finish that resists fingerprints while providing a premium tactile sensation. This texture also serves a practical purpose, enhancing grip without compromising on the device’s elegant appearance.
At just 8.2mm thick and weighing approximately 205 grams, the X300 Ultra strikes a commendable balance between screen size and manageability. The device is available in four sophisticated colorways: Cosmic Black, Ocean Blue, Titanium Gray, and the signature Sunrise Gold, which features a color-shifting effect that changes hues depending on how light strikes the surface.
The front of the device is dominated by a 6.78-inch AMOLED display with micro-curved edges that flow seamlessly into the frame, creating an immersive viewing experience without the practical drawbacks of extreme curved displays. Protection comes in the form of Corning’s latest Gorilla Glass Victus 2, offering enhanced drop and scratch resistance.
Vivo has also prioritized durability with an IP68 rating for dust and water resistance, allowing the device to withstand submersion in up to 1.5 meters of fresh water for 30 minutes. This represents a significant improvement over previous Vivo flagships and brings the X300 Ultra in line with other premium offerings in the market.
Vivo X300 Ultra 5G Display Technology
The centerpiece of the Vivo X300 Ultra is undoubtedly its exceptional display. The 6.78-inch E6 AMOLED panel delivers 2K resolution (3200 x 1440 pixels) with a pixel density of approximately 517 PPI, ensuring crisp text and detailed images. The display supports a variable refresh rate ranging from 1Hz to 120Hz, dynamically adjusting based on content to balance smoothness and battery efficiency.
Peak brightness reaches an impressive 2,800 nits, ensuring excellent visibility even under direct sunlight. The display also supports 10-bit color depth, covering 100% of the DCI-P3 color gamut and receiving DisplayMate’s highest A+ rating with 15 display performance records.
For gamers and video enthusiasts, the X300 Ultra offers HDR10+ and Dolby Vision support, with local dimming zones that enhance contrast by selectively adjusting brightness across different screen areas. The under-display fingerprint sensor has been upgraded with ultrasonic technology that works reliably even with wet fingers, a notable improvement over optical sensors in previous generations.
Vivo X300 Ultra 5G Camera System: A New Benchmark
The Vivo X300 Ultra truly distinguishes itself with its revolutionary camera system, developed in partnership with ZEISS. The quad-camera array is housed in a distinctive circular module that has become something of a signature element in Vivo’s design language.
At the heart of this system is a 50MP primary camera utilizing Sony’s latest 1-inch type sensor with a custom-developed V2 imaging chip. This combination delivers exceptional light-gathering capabilities and computational photography prowess. The lens features a variable aperture mechanism that can physically adjust between f/1.4 and f/4.0, providing unprecedented control over depth of field and exposure in smartphone photography.
Complementing the main sensor is a 50MP ultra-wide camera with a 114-degree field of view and auto-focus capability, allowing it to double as a macro shooter. The third sensor is a 64MP periscope telephoto camera offering 3x optical zoom and up to 100x digital zoom with remarkable clarity retention thanks to enhanced optical image stabilization.
The fourth camera is perhaps the most innovative: a 50MP free-form lens that captures images with a distinctive perspective similar to a 35mm prime lens, ideal for street photography and portraits. All four cameras benefit from ZEISS T* coating, which reduces flare and ghosting while enhancing color accuracy.
Video capabilities are equally impressive, with 8K recording at 30fps, 4K at up to 60fps with Dolby Vision support, and advanced stabilization through both optical and electronic means. The new “Cinema Mode” offers professional-grade video features including LOG profile recording, custom LUTs, and manual focus pulling, essentially transforming the smartphone into a pocket cinema camera.
The front-facing camera hasn’t been neglected, featuring a 32MP sensor with autofocus and a wider field of view than its predecessors, making group selfies easier to capture without a selfie stick.
Vivo X300 Ultra 5G Performance and Hardware
Powering the Vivo X300 Ultra is the latest Snapdragon 8 Gen 3 processor, manufactured on TSMC’s 4nm process. This chipset delivers approximately 30% better CPU performance and 25% improved graphics rendering compared to its predecessor, while also being more energy efficient.
The device comes with 12GB of LPDDR5X RAM as standard, with options for 16GB in higher-tier configurations. Storage options include 256GB, 512GB, and 1TB variants using UFS 4.0 technology, which offers sequential read speeds of up to 4,200MB/s—nearly twice as fast as the previous generation.
Thermal management has received significant attention, with a vapor chamber cooling system that’s 50% larger than in previous models. This advanced cooling solution helps maintain peak performance during extended gaming sessions or when using demanding applications like video editing.
Vivo X300 Ultra 5G Battery Life and Charging
The X300 Ultra houses a substantial 5,500mAh silicon-carbon battery that represents the latest advancement in lithium-ion technology. This high-density cell offers approximately 10% more capacity than conventional lithium-polymer batteries of the same physical size.
Charging capabilities are equally impressive, with 100W wired fast charging that can replenish the battery from 0% to 50% in just 15 minutes and achieve a full charge in approximately 35 minutes. Wireless charging hasn’t been overlooked, with 50W wireless fast charging support for compatible Qi chargers.
The device also supports reverse wireless charging at 10W, allowing it to function as a power bank for other devices like wireless earbuds or smartwatches.
Vivo X300 Ultra 5G Software Experience
The Vivo X300 Ultra runs Funtouch OS 14, based on Android 14, with a commitment to three years of OS updates and four years of security patches. The interface has been refined to offer a cleaner, more intuitive experience with reduced bloatware compared to previous iterations.
Vivo has introduced several AI-powered features, including an advanced on-device voice assistant that can perform complex tasks like summarizing articles, transcribing meetings, and translating conversations in real-time without requiring cloud processing. This approach enhances both privacy and speed.
The photography experience is augmented by AI scene recognition that can identify over 30 different scenarios and adjust settings accordingly. Portrait enhancements now offer more natural results with improved edge detection and realistic bokeh simulation based on actual optical characteristics of ZEISS portrait lenses.
For gamers, the updated Game Space feature provides tools to optimize performance, block notifications, and record gameplay. The new “Competition Mode” allocates maximum system resources to the game while minimizing background processes.
Vivo X300 Ultra 5G Connectivity and Audio
As the name suggests, the X300 Ultra supports 5G connectivity across a wide range of bands, ensuring compatibility with networks worldwide. Wi-Fi 7 support is included, offering theoretical speeds of up to 40Gbps when connected to compatible routers.
Bluetooth 5.3 with aptX Lossless and LDAC codecs ensures high-quality wireless audio streaming, while the dual stereo speakers tuned by Harman Kardon deliver impressive sound with Dolby Atmos support. The X300 Ultra retains a USB-C port but has followed industry trends by removing the 3.5mm headphone jack.
Location services have been enhanced with support for dual-frequency GPS (L1+L5), Galileo, GLONASS, BeiDou, and QZSS, providing more accurate positioning even in challenging environments like urban canyons.
