Chinese smartphone makers like OnePlus, Vivo, and Xiaomi are leading the way in battery innovations. With advancements in battery technology, these companies have been able to integrate large battery cells into slim devices. Recently, it looks like OnePlus is aiming to set a new record with the largest mobile battery in the world. Here’s what we’ve found out.
OnePlus May Be Developing an 8,000mAh Battery
OnePlus 13R Battery
For those who might not know, these Chinese brands are using new silicon-carbon (Si/C) battery tech to fit large cells in their phones. According to Digital Chat Station, OnePlus (and possibly Oppo too) might be in the process of creating a battery with a huge 8,000mAh capacity. The well-known tipster suggests that this increase in battery size is achievable due to the silicon content rising to 15 percent, which is a significant increase from the 6 percent seen in the OnePlus Ace 3 Pro (Review).
Silicon’s Advantages in Battery Technology
To put it simply, silicon can hold more lithium ions compared to graphite, which is why we have noticed bigger capacity batteries in the latest flagship smartphones from China. In addition to its impressive capacity, this next-gen battery is expected to support 80W SuperVOOC wired fast charging. While OnePlus might not roll out an 8,000mAh battery right away, it’s likely that a flagship model with a 7,000mAh battery could be coming soon.
Research and Development Insights
As per Digital Chat Station’s reports, the new battery technology is being developed by Ouga Lab, a research team associated with OnePlus and Oppo. However, it’s important to remember that this information is not yet officially confirmed, so it’s best to approach this news cautiously.
