As Vivo prepares for a major launch event in March 2026, rumored to feature the X300 Ultra, new details have surfaced about a more incremental upgrade in the pipeline. A fresh leak from a prominent tipster has painted a detailed picture of the upcoming Vivo X300s, suggesting it will pack significant upgrades in processing power, battery life, and camera hardware, potentially setting a new benchmark for the brand's flagship offerings in the coming year.
Key Specifications and Design Details
According to the leak from tipster Digital Chat Station, the Vivo X300s is expected to sport a 6.78-inch flat OLED display with a 1.5K resolution, framed by slim and nearly uniform bezels on all four sides for a modern, immersive look. The design language on the back continues with a prominent circular camera module, a signature element in Vivo's recent high-end models. This aesthetic is reportedly shared with the more premium X300 Ultra, which is said to feature a similar large circular module and a flat metal frame, though it may boast a slightly larger 6.82-inch 2K screen from Chinese manufacturer BOE.
Rumored Vivo X300s vs. X300 Specifications
| Feature | Vivo X300s (Rumored) | Vivo X300 (Announced Oct 2025) |
|---|---|---|
| Display | 6.78-inch, 1.5K OLED, flat, four narrow bezels | (Info not provided in source for direct comparison) |
| Chipset | MediaTek Dimensity 9500 Plus | MediaTek Dimensity 9500 |
| Rear Camera | 200MP main + mid-tier periscope telephoto | (Info not provided in source for direct comparison) |
| Battery | ~7,000mAh (silicon-based rumored) | 6,040mAh |
| Fingerprint Sensor | Ultrasonic in-screen | (Info not provided in source for direct comparison) |
| Other Features | Waterproof chassis | (Info not provided in source for direct comparison) |
Performance and Imaging Upgrades
The most notable internal upgrade for the X300s appears to be its chipset. The device is tipped to feature the yet-unannounced MediaTek Dimensity 9500 Plus, described as an overclocked version of the standard Dimensity 9500. This promises a tangible boost in CPU and GPU performance for demanding tasks and gaming. On the imaging front, Vivo seems to be doubling down on high-resolution sensors. The X300s is rumored to carry a formidable 200-megapixel primary camera, supported by a mid-range periscope telephoto lens, indicating a strong focus on both detail and optical zoom capabilities.
Battery and Charging Innovations
Perhaps the most eye-catching rumored specification is the battery. The X300s is said to house a massive cell with a capacity "around 7,000mAh," a substantial jump from the 6,040mAh unit found in the standard X300. Reports from Chinese sources suggest this could be enabled by new silicon-based battery technology, which offers higher energy density. In related news, there are also whispers that the Dimensity 9500 series platform may natively support magnetic wireless charging. While this feature is reportedly facing challenges related to device thickness in current prototypes, its potential inclusion in future flagships could significantly enhance convenience.
Market Availability and Global Strategy
The leak also provides insight into Vivo's regional release strategy. It is suggested that the X300s may initially launch exclusively in the Chinese market, following a pattern set by its predecessor, the X200s. That model debuted in China in April 2025 and is expected to be rebranded as the Vivo X200T for global markets in early 2026. By this logic, the X300s could see a global release under the "X300T" moniker sometime in 2027. This staggered approach allows Vivo to refine the product and software based on initial market feedback before a wider rollout.
Expected Vivo Launch Timeline (Based on Rumors)
- Early 2026: Global launch of Vivo X200T (rebranded X200s).
- March 2026: China launch event for Vivo X300 Ultra, Vivo X300s, and Vivo's first action camera.
- 2027: Potential global launch of Vivo X300T (rebranded X300s).
Conclusion and Context
The leaked specifications for the Vivo X300s point to a device that is more than a simple refresh. With a top-tier overclocked chipset, a groundbreaking large-capacity battery, and a high-resolution camera system, it aims to address core user demands for performance, endurance, and photography. As the March 2026 launch event approaches, where Vivo is also expected to unveil its first action camera, the X300s shapes up to be a critical product that could strengthen Vivo's position in the competitive high-end smartphone segment, provided these promising rumors translate into reality.
