OPPO is gearing up to hold a new product launch event, where it will unveil its latest flagship smartphones—the Find X9 series. The leader of the Find product line announced that the entire series will feature high-capacity Glacier batteries, each boasting a capacity exceeding 7,000mAh. These batteries promise longer and more enduring battery life, surpassing 60 months of usage and maintaining exceptional health and durability for over five years. Researchers have carried out in-depth exploration of silicon materials and developed an exclusive silicon-anode longevity algorithm. This innovative algorithm, for the first time, enables precise calculation of silicon-anode impedance and potential control, boosting the accuracy of battery health estimation by more than fivefold. The algorithm is capable of monitoring silicon material usage in real-time and regulating the silicon's longevity, ensuring that the battery remains robust even after 60 months of use and retains a health level above 80% after five years.
