A new smartphone battery with a capacity exceeding 12,000mAh has reportedly entered mass production, according to well-known tipster Digital Chat Station, who recently shared the information in a post on Chinese social media platform Weibo.
The tipster mentioned the “blue‑themed” brand, which many think is vivo, won’t get left behind when it comes to bigger phone batteries. The leak says the battery can hit over 12,000mAh typical capacity, with a rated capacity of 11,970mAh. If that pans out, it’s a pretty big leap for smartphone battery sizes.
The specific device expected to feature the battery remains unknown. However, Digital Chat Station also suggested that even larger battery designs are being developed, with future smartphones potentially combining these high-capacity cells with a new large-screen form factor.
This shows how phone makers keep putting more focus on battery life. They keep moving past the 10,000mAh mark. Capacities that used to be rare are slowly turning into a more common phone feature, especially from Chinese‑based brands.
Currently, one of the largest batteries in vivo’s smartphone lineup is found in the vivo Y600 Pro, which features a 10,200mAh BlueVolt battery. The device uses fourth-generation silicon-anode technology and second-generation semi-solid-state battery technology to deliver high energy density while maintaining a relatively slim design. According to vivo, it can provide more than 24 hours of endurance in certain light-use scenarios and over 12 hours under heavier workloads.
Another notable entry is the vivo V80 Lite 5G, which comes with a 10,000mAh BlueVolt battery. The device brings ultra-large battery capacity to vivo’s V series while maintaining a more balanced set of features.
From what Digital Chat Station shared about the “blue‑themed” brand, the rumored battery is most probably for vivo. If its stated capacity goes over 12,000mAh, it will have around 18 percent more power than the 10,200mAh battery found in the vivo Y600 Pro.
However, the rumored battery and its mass-production status have yet to be officially confirmed by vivo. Its eventual commercial availability, as well as the smartphone that could carry it, remains uncertain.
