Why is the power of the host still declining after connecting the expansion battery?

1. What actually drives the device is the built-in battery of the host. The expansion battery is only responsible for replenishing power and does not provide continuous direct power supply. In order to balance efficiency and battery life, the expansion battery starts charging when the host power is lower than 40%, and stops when it reaches 80%.

Therefore, the periodic decrease in the power of the host is not necessarily abnormal.
