vivo has confirmed that it will soon unveil the X300s in China. The company has also revealed some key specifications of the handset, which recent leaks had referred to as the X300 Max. The upcoming ‘s’ variant is likely to go official alongside the vivo X300 Ultra.
The confirmation comes from vivo’s Product Manager Han Boxiao, who shared the details on Weibo. The vivo X300s will be a larger and improved version of the standard X300.

It will feature a flat 6.78-inch AMOLED display using a BOE Q10+ panel. The screen will support a 144Hz refresh rate, 1.5K resolution, and Circular Polarization Light 2.0 technology, which is said to offer improved eye protection.

The vivo X300s will also be equipped with dual 1511 symmetric speakers and support the Super-sense Gaming Audio Zone feature, which vivo claims can improve in-game audio detail by up to 120%.

Further, the phone will come with the 751440 vibration motor that is said to offer improved haptic feedback.
Notably, the vivo executive also confirmed that the X300s will feature a 200MP main rear camera, but did not reveal any additional details about the rest of the camera system.
According to recent leaks, the handset could be equipped with the Dimensity 9500 SoC. It is rumored to offer a 50MP periscope telephoto camera, a 7,000mAh battery, and an IP69 rating.
