Vivo has officially confirmed the release date of the X300 Ultra and the X300s. The teasers also offer a first look at the design of both devices, showcasing a two-tone green colorway.

The Vivo X300 series is a flagship camera-centric lineup, and it is set to expand with two new devices: the Vivo X300 Ultra and the Vivo X300s. The company has now confirmed the release details of both smartphones, along with a first look at both devices.

The Vivo X300 Ultra and the Vivo X300s will be launched on March 30 in China at 19:00 local time. The teasers give a first glimpse at the design of the two phones in a two-tone green colorway. The design language of both devices is similar to the previous X300 models, with a large circular rear camera module.

For those unaware, the X300 Ultra will be positioned as the top-of-the-line offering in the X300 lineup. One of the key highlights of the device will be its Zeiss-branded camera setup featuring a 200MP primary camera, along with a 200MP telephoto sensor compatible with 200 mm and 400 mm teleconverter accessories. It is expected to use the Snapdragon 8 Elite Gen 5, the same chip found on the gaming-centric RedMagic 11 Pro (currently $949 on Amazon).

Meanwhile, the Vivo X300s will be the first smartphone in the Vivo X series to feature a 144Hz display. Another highlight of the X300s is its large 7,100mAh battery. For comparison, the standard Vivo X300 uses a 6,040mAh battery. Additionally, the X300s will feature a 200MP Zeiss camera setup. It is expected to be powered by the Dimensity 9500 chipset. As of now, there is no word on a global release date for the X300 Ultra and X300s.
