Vivo X300 Ultra Teardown by WekiHome Reveals Sony Lytia 901 Sensor Upgrades Redesigned Motherboard and Expanded Thermal Systems for Flagship Camera Performance
The internal assessment of Vivo X300 Ultra which YouTube technical channel WekiHome conducted demonstrates how the manufacturer achieved its flagship camera goals through physical design limits. The device teardown shows that the marketing claims for its imaging capabilities are supported by an internal design choice which allocates excessive chassis space for camera components.
The configuration uses the Sony Lytia 901 sensor as its main upgrade path. The X300 Ultra transitions from its predecessor's 1/1.28 inch Lytia LYT 818 sensor to a more expansive 1/1.12 inch sensor size. The sensor's physical dimensions have necessitated a complete redesign of the device's internal structure. The motherboard now serves as an upgraded structural element which uses its central opening to store the large optical system while creating a compact area for essential processing components.
The design process for this iteration emphasizes two areas which include thermal management systems. The teardown shows that the vapor chamber has undergone a substantial increase in size when compared to previous system designs. The expanded cooling surface area enables the system to manage heat output generated by both the high resolution imaging system and the flagship processing unit.
The layout shows how the Vivo X300 Ultra design moves away from modular internal systems towards a hardware integrated system which requires complete measurement of every millimeter. The WekiHome footage provides a conclusive demonstration of how modern flagship phones increasingly develop their identity through their oversized optical stacks which require additional physical space to accommodate advanced sensor technology.
