The Vivo X300 is more than just a smartphone; it is Vivo’s decisive answer to the call for a no-compromise, compact flagship in the era of oversized devices. Launched in India on December 10, 2025, the X300 achieves a masterful balance: it integrates an industry-leading camera system, top-tier performance hardware, and an exceptional battery into a chassis that is genuinely comfortable for one-handed use. It is positioned as the definitive choice for users who demand professional-grade photography and all-day endurance without the bulk of a “Pro Max” model.

This detailed, expert review dissects the now-confirmed specifications of the Vivo X300, analyzing the real-world performance of its Dimensity 9500 chipset, the technical prowess of its ZEISS-tuned camera array, and its significant value proposition in the ultra-competitive Indian premium market.

Specifications and Design: Compact Powerhouse with IP69 Rating

The Vivo X300 challenges expectations with its compact size (6.31-inch display) and premium construction. The phone features a flat front, back, and sides, moving away from the curved displays of its predecessors—a design choice prioritizing usability and grip. It boasts a high-end build, certified with both IP68 and IP69 ratings, making it resistant not just to dust and water immersion but also to high-pressure, high-temperature water jets.

The engine room of the X300 is unequivocally flagship-grade:

• Processor: The phone is powered by the MediaTek Dimensity 9500 processor (3nm fabrication). This processor is MediaTek’s equivalent to the latest Snapdragon 8 Elite Gen 5, featuring a highly advanced core architecture clocked up to an aggressive 4.21 GHz.
• Co-Processor: The performance is augmented by Vivo’s proprietary V3+ Imaging Chip, which handles intense computational photography tasks, freeing the main CPU for seamless multitasking and gaming.
• RAM/Storage: Available in configurations up to 16GB LPDDR5X RAM and 512GB UFS 4.1 storage, ensuring lightning-fast application load times and data transfer speeds.
• Software: It runs the refined and aesthetically pleasing OriginOS 6 based on Android 16, offering a clean, fluid user interface that critics have praised for its polished animations and stability.

Camera Quality: The ZEISS 200MP Triple Threat

The camera system on the Vivo X300 is its defining strength, built on a versatile and uncompromising triple-lens ZEISS-tuned array:

• Primary Sensor: A massive 200MP Samsung HPB sensor ($f/1.68$ aperture) with a large 1/1.4-inch sensor size and Optical Image Stabilization (OIS). This sensor captures incredible detail, relying on advanced pixel-binning for exceptional low-light performance. Photos are noted for their supreme texture details, wide dynamic range, and vibrant (though sometimes slightly saturated in ZEISS mode) colors.
• Telephoto Sensor: A 50MP sensor offering 3x optical zoom (70mm equivalent) with OIS and Autofocus. This lens delivers sharp, stable, and naturally separated portrait shots, with the ability to digitally reach 100x magnification. The optional ZEISS 2.35X Extender Kit further pushes optical capability, a unique feature for professional users.
• Ultrawide Sensor: A high-resolution 50MP Ultrawide sensor with Autofocus, providing excellent detail and color consistency that aligns well with the main lens.
• Front Camera: A 50MP Autofocus front camera is a significant upgrade, delivering consistently sharp, color-accurate selfies and high-quality 4K video recording.

The entire imaging pipeline, managed by the V3+ chip and ZEISS T* coating, ensures controlled highlights, accurate skin tones, and minimal lens flare, cementing the X300’s status as a top-tier photographic tool.

Gaming Performance and Stability

Despite its compact size and photography focus, the Vivo X300 is a highly capable gaming machine, thanks to the Dimensity 9500 chipset and superior thermal engineering.

• Performance: The Dimensity 9500 delivers top-tier performance, handling graphically demanding games like CarX Street and BGMI with ease. Users report smooth, fluid frame rates and virtually no UI stutters, even when managing multiple social media apps simultaneously.
• Cooling: The phone features a sophisticated Glacier Liquid Cooling System that provides excellent thermal conductivity. Review testing showed the X300 remains remarkably cool even during intense gaming sessions lasting two to three hours. The phone’s ability to remain calm under heavy usage is a significant advantage over many rivals.

The flat display and balanced 190g weight contribute to a comfortable grip during extended gameplay, making the X300 an excellent choice for casual and competitive mobile gamers alike.

Battery Life and Charging Speed

The Vivo X300 packs a substantial 6,040mAh battery. While not the absolute largest capacity in the segment (some rivals reach 7,000mAh), the battery’s performance is optimized by the 3nm Dimensity 9500 and the adaptive 120Hz LTPO display.

• Endurance: In real-world usage, the 6,040mAh battery comfortably lasts a full day of heavy use and often extends into a second day with moderate usage. The efficiency of the LTPO panel and power management ensures the battery drain is minimal, even with the 120Hz mode active.
• Fast Charging: The phone supports extremely fast 90W FlashCharge wired charging, capable of fully replenishing the 6,040mAh battery in approximately 47 minutes.
• Wireless Charging: A major new feature for the standard X-series is the inclusion of 40W wireless charging and reverse wireless charging support, providing premium convenience.
