vivo may soon enter the growing group of brands pushing battery capacity past the 10,000mAh mark. According to known tipster Digital Chat Station, the company is currently testing a phone equipped with a massive silicon-carbon battery.

Translation: Exclusive: A new phone from Blue Factory with a 10,000mAh-class large battery is currently in testing. It uses a 4.53V single-cell silicon battery with a rated capacity of 10,000mAh, and a typical capacity of around 11,000mAh–12,000mAh. It’s finally here.

In a post on Weibo, the tipster claimed that vivo is working with a 4.53V single-cell silicon battery that has a rated capacity of 10,000mAh. However, its typical capacity is said to range between 11,000mAh and 12,000mAh, which explains the 12,000mAh figure circulating in reports.

If accurate, this would place vivo ahead of most mainstream smartphones in terms of raw battery size.

The device is reportedly still in the testing phase, meaning it is unlikely to launch in the immediate future. Extensive evaluation would be required before commercialization, especially for a battery this large.

The phone is also not expected to be a flagship model. Instead, it could debut as a mid-range device or potentially under vivo’s iQOO sub-brand, which often experiments with aggressive hardware configurations.

Several manufacturers have recently introduced phones with batteries at or above the 10,000mAh threshold.

  • Honor Power2 followed with a slightly larger 10,080mAh cell.

Compared to these, a vivo device reaching up to 12,000mAh would represent a notable jump in capacity.

For now, this remains an unconfirmed leak. vivo has not officially acknowledged the device, and no details about its processor, display, cameras, or charging speeds have been shared. More information is likely to surface if the phone progresses beyond internal testing.
