Before the machine leaves the factory, the system needs to be installed, so it must be charged to about 60%, and after the system is installed, there may only be 30-40% of the electricity. So these batteries can be used for half a day at most.

Charge it when you run out, the first 3 times may not be fully awakened, the time used is relatively short, and it will be normal later.

According to your description, this situation may be that your battery is too low, and you can continue to shut down and charge for a period of time to observe.
