The vivo X300 Ultra is poised to be the final model in the X300 series, succeeding the X200 Ultra. Although vivo has not yet made any official announcements about this Ultra variant, recent leaks have shed light on its battery size and potential release date.
According to insider information, the X300 Ultra is expected to launch in the first quarter of 2026, which aligns well with the X200 Ultra’s debut back in April of this year. A notable upgrade is its battery capacity, rumored to be a massive 7,000mAh cell, surpassing the 6,000mAh battery found in the X200 Ultra and the 6,510mAh unit present in the new X300 Pro.
The device is also said to feature impressive camera hardware, including dual 200MP sensors sourced from Sony—one dedicated to the main camera and the other for the periscope lens. Additionally, the phone may sport a larger 50MP ultra-wide sensor to enhance photography capabilities. There are reports that the X300 Ultra will be available on a global scale, making it accessible to a wide audience.
With these specifications, the vivo X300 Ultra aims to push the boundaries of smartphone technology, particularly in battery endurance and photography. Enthusiasts eagerly await the device and hope future models, like a potential X400 Ultra, will bring further innovations such as advanced zoom sensors. Overall, the X300 Ultra looks set to build on vivo's momentum in delivering flagship devices that appeal to power users.
