Tech enthusiasts anticipating the arrival of the vivo X300 Ultra are getting a closer look, with leaked images and specifications surfacing ahead of its official debut later this month. The upcoming device is generating buzz for its large-capacity battery, a flat-screen design, and an upgraded professional-grade camera system.
A key highlight of the X300 Ultra is its increased battery capacity, now reaching 6,700mAh. The phone utilizes the latest BlueVolt technology, making it the largest battery in vivo’s Ultra series to date. Despite the larger battery, the device maintains a slim profile consistent with flagship smartphones, avoiding excessive thickness or weight.
 
The leaked images reveal the adoption of a Flat Display, aligning with a growing trend for 2026. This design choice prioritizes ease of use and simplifies screen protector application.
- Screen size: 6.82 inches
- Resolution: 2K
- Panel: LTPO 120Hz
- Bezels: Uniformly thin on all four sides
The overall effect is an immersive, edge-to-edge viewing experience suitable for both gaming and everyday use. This focus on display quality reflects the increasing importance of visual experiences in modern smartphones.
The camera remains a central selling point, now featuring a 200MP Sony LYT-901 sensor with a 35mm focal length, aiming for more natural-looking photographs. The device also incorporates professional-grade Zeiss lenses, emphasizing realistic color tones and improved portrait photography.
According to leaked information, the vivo X300 Ultra aims to be a well-rounded flagship device, combining a long-lasting battery, a user-friendly display, and a professional-level camera. The official launch is scheduled for March 30.
