Nubia NaviX Ultra Announced with 7,100mAh Battery in a 7.62mm Body
Nubia has officially announced the NaviX Ultra smartphone launching on September 16, featuring a massive 7,100mAh silicon-carbon battery inside a slim 7.62mm body. Co-developed with ByteDance, the device integrates the Doubao AI assistant and premieres domestic CXMT LPDDR5X RAM operating at 10,667Mbps. The launch highlights significant advances in smartphone packaging by combining high energy density with an ultra-thin profile through silicon-carbon battery technology. Furthermore, it represents a key milestone for China's domestic semiconductor industry as CXMT's high-speed mobile DRAM reaches commercial application. The device is expected to pack a flagship Snapdragon 8 Elite Gen5 processor, a 50MP triple-camera setup including a periscope telephoto lens, and up to 100W wired fast charging. Key supply partners for the smartphone include Qualcomm, BOE, CXMT, Samsung Semiconductor, and Goodix.
## BACKGROUND
Silicon-carbon anode technology replaces standard graphite with silicon-carbon composites in lithium-ion batteries, dramatically improving energy storage density without adding physical bulk. CXMT (ChangXin Memory Technologies) is a major Chinese DRAM manufacturer producing high-speed LPDDR5X chips to supply mobile and computing hardware.
