Solution:
The built-in battery (non-removable) of Xiaomi notebook has about 800 charge and discharge cycles, and the battery capacity is still more than 70% of the design capacity. According to the standard of charging once a day, the original battery capacity can be used for nearly three years, even if it is charged and discharged. After 800 cycles, it can still be used normally. So no need to worry about battery life.
