Tips: It is normal to use the battery for 1-5 times. The battery will power down very quickly. The virtual power in the battery will cause power failure, and the battery is virtual before leaving the factory. It is recommended to start charging at 15% for the first time, not at 0% - 5%, otherwise the battery will fail to activate and cannot be recharged again. The new battery needs to be cycled for 10-15 times to drain the virtual power. After charging 100%, it can be charged for 1-2 hours to better activate the battery, and the use time is longer.
