"BatteryLog" displays your battery usage in graph.
It acquires battery data upon launch and record log data in a timeline.

* Graph can be displayed both vertically and horizontally.
* You can send CSV converted log data by e-mail.
* When data is updated while charging, graph will be highlighted.
* Scale slider is available for zoom-in/zoom-out.
* Charging cycle (accumulated 100% counted as 1) shown in settings window. Note: Cycle counts are based on the log data acquired by BatteryLog.

1. "BatteryLog" is not capable of auto-updating. To get the latest data, you must launch application by yourself.
2. Note that all data is acquired in percentage. It is not actual voltage.
