The widget can be activated by clicking on a free space on the homescreen and selecting "Widgets" then "Bat Stat". Once activated, the widget displays all relevant battery information, including level, voltage, and temperature. The values are updated in real-time as the battery status changes, and the temperature and capacity icons change according to the battery state. Additionally, users can tap the widget to flip between Celsius and Fahrenheit temperature displays.
