This is not normal. The normal health value of the new battery is within 10%. It may be that the activation was not done well at the factory, or the battery was indeed used. If the notebook computer is just bought, the battery will be in a higher health level, and it is normal for the new battery to wear less than 5%. If the notebook computer is used for a long time, the battery loss will be relatively large. In addition, when using the notebook, it is best to use it at a suitable temperature, and the ambient temperature should not be too high or too low, so that the battery health of the notebook computer will be better.
This health value will be updated after each charge and discharge, and the loss of each update actually fluctuates by about 3%. For this kind of loss, we can try to repair the battery cycle, that is, carry out a full charge and discharge process to keep the battery in the best state (once a month later). The following are ways to recycle batteries:
1. Fully charge the battery when it is turned off;
2. Turn it on and let it discharge automatically until there is no electricity. It is best not to operate the computer during this period;
3. Fully charge again, whether it is turned on or not.
