According to the Chinese insider Digital Chat Station, as reported by ixbt.com, an unnamed manufacturer has already set up mass production of a battery with a nominal capacity of 11,970 mAh ixbt.com. This corresponds to the 12,000 mAh class. The insider did not name the brand, but the colour scheme of the "blue" phone maker points to Vivo, he said.

Vivo is also reportedly developing an even higher-capacity battery for a future device with a larger display. This may be a further development of silicon-carbon technology, which raises energy storage density without a proportional increase in cell size.

In February, Digital Chat Station reported that Vivo was testing a smartphone with a single-cell silicon battery of typical capacity from 11,000 to 12,000 mAh. At that time the development was at the testing stage.
