Oppo and OnePlus are reportedly working on a next-generation silicon-carbon (Si/C) battery with a massive 8,000mAh capacity, according to a well-known tipster on Weibo. The battery is said to support 80W SuperVOOC fast charging, matching the flagship charging speeds of their existing premium smartphones.
Breakthrough in Silicon-Carbon Battery Technology
The new Si/C battery is being developed at Ouga Lab, the joint R&D division of Oppo and OnePlus. The tipster, Digital Chat Station, revealed that the silicon content will be increased to 15%, a significant jump from the 6% silicon content found in OnePlus’ Ace 3 Pro (nord 3 in india), launched last year.
Silicon-carbon batteries offer:
- Higher energy density – Leading to extended battery life.
- Improved longevity – Enhancing durability compared to conventional lithium-ion batteries.
- Faster charging speeds – Optimizing power efficiency.
Will the 8,000mAh Battery Feature in Future Smartphones?
It is unclear whether Oppo and OnePlus will integrate this battery into their upcoming smartphones. However, if adopted, it could power flagship models like:
- The successor to the OnePlus 13
- Oppo’s anticipated Find X8 series
Chinese Brands Leading the High-Capacity Battery Race
The competition for high-capacity smartphone batteries is intensifying among Chinese manufacturers:
- Xiaomi and OnePlus were previously reported to be working on 7,000mAh battery smartphones for 2025.
- Current flagships, such as the Xiaomi 15 Pro (6,100mAh) and OnePlus 13 (6,000mAh), are already pushing battery limits.
What This Means for Consumers
With rapid advancements in battery technology, users can expect:
- Longer battery life – Reduced charging frequency.
- More powerful smartphones – Supporting demanding apps and AI-driven features.
- Faster charging speeds – Less downtime for recharging.
While Oppo and OnePlus have not officially confirmed this development, the 8,000mAh silicon-carbon battery could be a game-changer in smartphone battery innovation if implemented in future flagship devices.
