EDITORIAL: (this is a pre-test listing based on reasonable expectation of battery, screen and imaging performance) The second flagship Motorola phone comes with considerable increase in weight, size, processing power, battery, screen and price. Still present are industry leading drop protection, OS support length and desktop replacement functionality. If you're okay with its 77mm(3.03in) width, you need to consider getting this phone.

EDITORIAL: Unlike X200 Ultra, the X300 Ultra is sold outside of China. Vivo is delivering it's finest camera-phone by putting a double 200MP sensor camera (industry first) and offering not one but two optional tele lenses (a 200mm and a 400mm). Lenses are still Zeiss, sensors by Sony & Samsung but
like with other current Vivo's phones: all camera magic is home grown.
