Currently, flagship models from Xiaomi and OnePlus include batteries ranging from 6,000mAh to 6,100mAh, offering a glimpse into the direction the brands are heading with power capacities in their upcoming devices.

Chinese Brands Adopting Silicon Carbon Batteries

In addition to Oppo and OnePlus, other Chinese manufacturers like Realme and iQOO are also incorporating Silicon Carbon technology. Realme's Neo 7 in China comes with a 7,000mAh battery, underscoring the growing trend among smartphone makers to adopt this new battery technology, which is believed to offer several advantages over traditional lithium-ion options. The shift towards Silicon Carbon could represent a significant leap in battery life and performance for future smartphones.
