The vivo X300 Pro has been spotted in the 3C database, having been certified by the Chinese authority recently. This has revealed the fact that it will support 90W wired charging, which is identical to its predecessor.
We've been hearing a lot about vivo X300 Pro's camera upgrades - the upcoming camera flagship is said to use Sony's LYT-828 1/1.3" sensor (an improved version of the LYT-818 used in the X200 Pro and Ultra) and an upgraded 200MP telephoto module. The telephoto module will use a 200MP sensor from Samsung. Vivo exec Han Boxiao revealed on Weibo that this sensor is "deeply customized" and vivo will have exclusive use of it. It's called the ISOCELL HPB "Thanos".
