Vivo’s upcoming flagship, the Vivo X300 Ultra, is shaping up to be one of the most anticipated smartphones of 2026. Though the company has not officially confirmed any specifications, a steady stream of leaks has provided a clearer picture of what to expect from the final model in the X300 lineup. Positioned as the successor to the X200 Ultra, the device is expected to deliver meaningful upgrades in performance, battery technology, and camera capabilities.
As the last model in the X300 series, the X300 Ultra is rumored to bring several enhancements designed to set it apart from its predecessors and the recently launched X300 Pro.
According to the latest leak, the Vivo X300 Ultra may pack a substantial 7,000mAh battery. This is a notable jump from the 6,000mAh cell found in the X200 Ultra and even exceeds the 6,510mAh battery used in the X300 Pro. If accurate, this would make it one of the largest battery capacities in mainstream flagship smartphones, potentially offering significantly longer screen-on time and improved efficiency in day-to-day usage.
The camera system is another area where the X300 Ultra is expected to make a statement. Early details suggest the device might feature dual 200MP sensors, allowing for highly detailed shots and superior zoom performance. Additionally, a larger 50MP ultrawide sensor is rumored to be included, enhancing the versatility of the camera setup and improving low-light imaging.
Unlike some of vivo’s Ultra models that were limited to select regions, the X300 Ultra is rumored to receive a global release. This would position it as a direct contender in the premium flagship segment worldwide. As the final release in the X300 series, the Ultra is expected to serve as the most advanced model, likely incorporating top-tier hardware and refined software capabilities.
A trusted tipster has suggested that the Vivo X300 Ultra is scheduled for a Q1 2026 launch. This timeline aligns with the release pattern of its predecessor, the X200 Ultra, which arrived in April 2025. If the leak holds true, vivo may follow a similar launch strategy for its upcoming flagship.
