Shenzhen, February 10: Oppo is reportedly testing a new battery technology that could significantly increase the endurance of its upcoming flagship smartphones. According to reports from the Chinese tech industry, the company has entered the trial production phase for a dual-cell battery system with a typical capacity of approximately 8,500mAh.

The development suggests that the next generation of premium devices, likely the Oppo Find X10 series, will continue the industry trend of prioritising high-capacity power cells. This move follows the recent release of the Oppo Find X9 series, which already established a high benchmark by surpassing the 7,000mAh threshold in certain configurations. Nothing Phone 4a Pro, Nothing Phone 4a Launch in India in March 2026; Check Rumoured Date, Specifications, Features and Price.

Advanced Dual-Cell Engineering and Charging Speeds

Technical details shared by industry tipster Digital Chat Station indicate that the new setup utilises two 4,190mAh cells. This configuration results in a combined rated capacity of 8,380mAh, which is expected to be marketed with a typical figure of 8,500mAh. Despite the substantial increase in size, the leak suggests the hardware will support 100W fast charging without the thermal throttling issues often associated with high-density batteries.

While the specific device for this battery has not been officially confirmed, analysts point toward a high-end variant of the Find X10 series. Beyond the battery improvements, early rumours regarding the Find X10 line suggest the devices may feature dual 200MP cameras and a next-generation processor, potentially from the MediaTek Dimensity 9600 class.

Competition and Market Trends in Battery Innovation

Oppo is not the only manufacturer pushing the boundaries of smartphone longevity. Chinese brands including Honor, Xiaomi, and Vivo are increasingly adopting silicon-carbon battery chemistry to achieve higher energy density. There is also speculation that this 8,500mAh unit could be utilised by OnePlus, although some reports suggest OnePlus is experimenting with even larger 9,000mAh capacities and 120W charging. POCO F9 Ultra Leaks Reveal 200MP Camera and Snapdragon 8 Elite Gen 6 for 2026 Flagship Killer; Check More Details.

As modern hardware demands more power, manufacturers are shifting their focus from software efficiency alone to increasing physical battery volume. The Find X10 series is tentatively expected to debut in late 2026, meaning specifications could still be adjusted before the final commercial launch.
