Oppo and OnePlus are working on a new battery with an impressive 8,000mAh capacity, according to details shared by a tipster. In a post on Weibo, the Chinese microblogging website, Digital Chat Station (translated from Chinese) claims that the new battery will 80W SuperVOOC charging, like the company's existing flagship smartphones. Chinese smartphone makers are racing ahead of their competitors with advanced Silicon Carbon (Si/C) battery technology, and future handsets are expected to arrive with additional improvements.

Ouga Lab, the combined research and development group that comprises Oppo and OnePlus teams, is testing a new battery, according to the post by Digital Chat Station. It is said to be a new silicon-carbon battery that has a capacity of 8,000mAh. It can be charged at around 80W, the tipster claims.

When OnePlus launched the Ace 3 Pro last year, the company claimed that its Si/C battery had the "highest silicon content" at the time — at 6 percent. The new battery being tested by Ouga Lab raises that amount to 15 percent, the tipster claims.

It's currently unclear whether the 8,000mAh battery will eventually make its way to Oppo and OnePlus handsets. If the companies decide to introduce the upgraded battery, we can speculate that it might arrive on a future flagship model, like the successors to the Oppo Find X8 series.

Last December, it was reported that both Xiaomi and OnePlus were working on new smartphones equipped with 7,000mAh batteries that could be launched in 2025. The companies' flagship Xiaomi 15 Pro and OnePlus 13 models are equipped with 6,100mAh and 6,000mAh batteries, respectively.

Similarly, the Chinese versions of the iQOO 13 pack 6,500mAh and 6,100mAh batteries. Chinese smartphone makes are equipping their handsets with silicon-carbon batteries, which offer many benefits over traditional lithium-ion (Li-ion) batteries.
