The vivo X300, released in October 2025, represents vivo’s vision of a true compact flagship that refuses to compromise on performance, camera capability, or long-term software support. With a refined design, a cutting-edge chipset, and one of the most advanced camera systems in its class, the X300 is clearly aimed at users who want a premium smartphone experience in a smaller, more manageable form factor. Running Android 16 out of the box with a promise of up to five major Android upgrades, the device is built for longevity as much as it is for performance.
Design and Build Quality
The vivo X300 immediately stands out due to its compact dimensions and premium materials. Measuring just over 150 mm in height and weighing 190 grams, it feels comfortable in hand while still offering the solid heft expected from a flagship device. The phone features a glass front and back paired with an aluminum alloy frame, giving it a clean and elegant look that feels durable and refined.
Durability is further enhanced by IP68 and IP69 ratings, making the X300 resistant to dust, water immersion, and even high-pressure water jets. This level of protection places it among the most rugged premium smartphones available. The reinforced display glass adds extra resistance against everyday scratches, ensuring the phone maintains its premium appearance over time.
Display and Visual Experience
The vivo X300 features a 6.31-inch LTPO AMOLED display that strikes an excellent balance between compact size and immersive visuals. With a resolution of 1216 x 2640 pixels and a high pixel density of around 460 ppi, the screen delivers extremely sharp text and detailed images. The LTPO technology allows the refresh rate to dynamically scale up to 120Hz, ensuring smooth animations while optimizing battery efficiency.
Color reproduction is outstanding, with support for one billion colors, HDR10+, HDR Vivid, and Ultra HDR images. Peak brightness reaching up to 4500 nits ensures excellent outdoor visibility, even under harsh sunlight. The high screen-to-body ratio further enhances immersion, making the display ideal for media consumption despite the phone’s compact footprint.
Performance and Software Experience
At the heart of the vivo X300 is the MediaTek Dimensity 9500 chipset, built on an advanced 3nm process. This processor is designed for flagship-level performance, featuring high-frequency cores that handle demanding tasks with ease. Whether it’s heavy multitasking, high-end gaming, or intensive productivity workloads, the X300 delivers consistently smooth and responsive performance.
The Arm G1-Ultra GPU ensures excellent graphical output, making the device well-suited for modern games and visually demanding applications. Combined with fast UFS 4.1 storage and generous RAM options, the phone feels exceptionally fluid in daily use.
On the software side, the X300 runs Android 16 with OriginOS 6. The interface is feature-rich yet polished, offering deep customization options while maintaining smooth animations and system stability. The promise of up to five major Android upgrades makes the X300 one of the most future-proof Android smartphones available.
Camera System and Imaging Capabilities
Photography is a major highlight of the vivo X300. The phone features a powerful triple camera system developed in collaboration with Zeiss. The primary 200-megapixel sensor captures incredibly detailed images with excellent dynamic range and reliable low-light performance, aided by optical image stabilization and advanced autofocus.
The 50-megapixel periscope telephoto camera offers 3x optical zoom, making it ideal for portraits and distant subjects without significant quality loss. Complementing this setup is a 50-megapixel ultra-wide camera with autofocus, which delivers sharp and distortion-controlled wide-angle shots.
Advanced imaging features such as Zeiss T* lens coating, laser autofocus, and support for professional-grade tools like 3D LUT imports make the X300 particularly appealing to photography enthusiasts and content creators. Video performance is equally impressive, with support for high-frame-rate 4K recording and HDR video capture.
The front-facing 50-megapixel camera is equally capable, delivering sharp selfies and supporting 4K video recording, making it suitable for high-quality video calls and vlogging.
Audio, Connectivity, and Sensors
The vivo X300 comes with stereo speakers that deliver clear and balanced audio, enhancing the experience of watching videos or playing games. While there is no headphone jack, support for high-quality wireless audio codecs ensures excellent sound with compatible wireless earbuds.
Connectivity options are comprehensive, including advanced Wi-Fi standards, Bluetooth 5.4, NFC, infrared support, and precise multi-band GPS. Security is handled by an under-display ultrasonic fingerprint sensor, which is both fast and reliable.
Battery Life and Charging
The global version of the vivo X300 is equipped with a 6040 mAh silicon-carbon battery, which is impressive given the phone’s compact size. This battery comfortably supports a full day of heavy usage and extends well into a second day with moderate use. Charging is another strong point, with support for 90W wired charging and 40W wireless charging, ensuring minimal downtime.
Conclusion
The vivo X300 is a standout compact flagship that delivers top-tier performance, an exceptional camera system, and a stunning display in a refined and durable body. With long-term software support, fast charging, and professional-grade imaging features, it is designed for users who want a powerful yet manageable smartphone without compromises.
