Advantages: When the 5V Charging power supply is connected, the load doesn't occupy the charging current of the battery, and the power supply can charge the battery efficiently and quickly while carrying the load. The battery will not always be in the charging state, and the charging chip will not participate in the loading, so the life of the battery and each functional chip will be longer.
