This is an optional step. This step can be skipped when users don't want to know the battery status or don't have the software.

Check the "cycle times" by battery software.

Suggested software: (1) BatteryInfoView, (2) BatteryMon.

Background: The number of "cycle times" depends on battery usage. It usually > 0. A Li-ion battery usually has "cycle times" about 500~1000. REF: https://doi.org/10.31224/osf.io/swcyg

For example: BatteryInfoView shows that "Number of charge/discharge cycles" is 306 (red box). BatteryMon shows that "Charge cycles" is 306 (blue box).
