Vivo X300 series will reportedly get two more smartphones, dubbed Vivo X300 Max and Vivo X300 Ultra, after the Chinese Spring Festival. This means that the handsets could be unveiled by the tech firm after March 3. However, the company has yet to confirm that these rumoured models are in development. In terms of specifications, the Vivo X300 Ultra is expected to sport a 6.82-inch 2K BOE flat LTPO display. It could be powered by a 3nm octa core Snapdragon 8 Elite Gen 5 chipset, paired with a 7,000mAh battery.
