As 2025 draws to a close, the rumor mill for 2026's flagship smartphones is already in full swing. Vivo's next imaging powerhouse, the X300 Ultra, is at the center of this early buzz. A series of leaks from reliable sources have painted a detailed picture of what to expect from this device, suggesting significant upgrades in display, battery, and camera technology, alongside a crucial strategic shift towards global availability.
The latest leak reveals key display and design changes
The most recent information, shared by prominent tipster Digital Chat Station, focuses on the phone's front panel and chassis. The Vivo X300 Ultra is said to feature a sizable 6.82-inch flat display supplied by BOE. This panel boasts a 2K resolution and utilizes an LTPO backplane, which allows for dynamic refresh rate adjustments to balance smooth visuals with power efficiency. The design is described as having a "four-sided narrow-bezel" look, maximizing screen real estate. In a notable departure from its predecessor, the engineering unit has reportedly removed the dedicated camera shutter button, dubbed the "Action button," found on the X200 Ultra. The tipster suggests this was a practical decision to reclaim internal space for other components, as the button's utility in daily use was deemed limited.

Under the hood: A powerhouse of performance and endurance
Beneath the surface, the X300 Ultra is shaping up to be a beast. It is all but confirmed to be powered by Qualcomm's top-tier Snapdragon 8 Elite Gen 5 chipset, ensuring it will be among the most powerful Android devices upon release. Perhaps even more impressive is the rumored battery capacity. Leaks point to a massive 7,000mAh battery, a significant jump that could translate to exceptional battery life, a critical factor for power users and content creators. The phone is also expected to feature an ultrasonic in-display fingerprint scanner for secure and fast unlocking and will run on OriginOS 6 based on the upcoming Android 16.
Camera system poised for a major leap
The "Ultra" moniker in Vivo's lineup has always been synonymous with camera innovation, and the X300 Ultra appears to continue this tradition ambitiously. Recent leaks suggest a sophisticated triple-camera array on the rear. The primary sensor is rumored to be the newly unveiled Sony LYT-901, a 200-megapixel powerhouse. It is tipped to support continuous optical zoom across multiple focal lengths, a feature that could offer more versatility than fixed-step zoom lenses. This would be complemented by a second 200-megapixel sensor and a 50-megapixel ultra-wide-angle camera, with the telephoto and ultra-wide sensors speculated to be the Sony LYT-828 and Samsung HPB, respectively. The large circular camera module from the X200 Ultra is retained, though the internal layout may have been adjusted.
A strategic shift towards a global launch
One of the most significant rumors surrounding the X300 Ultra isn't about its specs, but its market strategy. The Vivo X200 Ultra was launched exclusively in China, much to the disappointment of international photography enthusiasts. This time, evidence suggests a change in approach. A global variant of the X300 Ultra, identified by model number V2562, has reportedly cleared EEC certification in Europe, a strong indicator of an impending international release. The phone is expected to debut in its home market of China around March 2026, with a global rollout likely to follow. This move could position Vivo more directly against established global players in the premium smartphone segment.
What these leaks mean for the flagship landscape
The emerging profile of the Vivo X300 Ultra points to a device designed to compete at the very highest level. By combining a top-tier processor, an enormous battery, and a potentially groundbreaking camera system, Vivo is addressing key pain points for flagship users: performance, battery anxiety, and photographic versatility. The rumored removal of the gimmicky Action button in favor of more practical internal space reflects a focus on core functionality. If the global launch materializes, it will mark an important step for Vivo, bringing its most advanced camera technology to a wider audience and intensifying competition in the global premium market. While these details remain unconfirmed until an official announcement, they set high expectations for Vivo's 2026 flagship contender.
