Xiaomi 12S Series to Use Self-Developed Power Management Chip Surge G1

Lei Jun, Chairman and CEO of Beijing-based consumer electronics firm Xiaomi, continued to drum up interest in the brand’s upcoming 12S smartphone series on Friday. The company officially announced on Friday that its self-developed Surge G1 battery management chip will be released at 7:00 p.m. on July 4, and it will be installed in the Xiaomi 12S series.

Lei said that the combination of the Surge P1 fast-charging chip and the Surge G1 battery management chip has realized the independent development of battery management full chain technology. Xiaomi 12S Ultra, equipped with these two independently developed chips, monitors battery safety in real time at the millisecond level, greatly improves the accuracy of battery life prediction and effectively enhances the battery life.

Last year Xiaomi launched two self-developed chips, the Surge C1 and the Surge P1. The Surge C1 is Xiaomi‘s first professional imaging chip, while the Surge P1 is Xiaomi‘s first independently developed charging chip.

Meanwhile, Lei also announced that the new device will adopt a new battery material, that is, a new-generation lithium cobalt oxide battery, and negative battery electrode shunt technology, so that the maximum temperature of the battery will be reduced by 5 degrees Celsius when charging. The battery capacity of the Xiaomi 12S also increased by 100mAh to 4500mAh.

The “super-large cup” Xiaomi 12S Ultra will adopt the more advanced and expensive second-generation silicon-oxygen negative battery, with an energy density as high as 714Wh/L, which is four times the lithium-ion storage capacity of traditional graphite. Although Xiaomi has not announced the battery capacity, it should be no less than 4800mAh, supporting 67W wired fast charging and 50W wireless super flash charging.
