The Kirin 990 chip is a high-performance processor from Huawei that is widely used in many mobile phone models. However, the size of the battery capacity does not depend entirely on the chip model, but is determined by the phone manufacturer. Therefore, it is impossible to accurately answer which model has the largest battery capacity. Different phone brands and models have different designs and configurations, so battery capacity may vary. If you are interested in a specific model, it is recommended that you consult the detailed specifications for that model to understand its battery capacity.
