Battery Status and Temperature is a free Android app developed by Masami Software. It falls under the category of Utilities & Tools. The app offers four types of widgets: Simple, Vertical Graph, Horizontal Graph, and History.

The Simple widget displays the numerical values of the battery status and temperature. The Vertical Graph widget allows users to choose from two different designs. The app also provides a History widget.

In addition to the widgets, the app itself displays the battery status, temperature, and history. Users can customize the text size of the history display.

When the app is launched for the first time, a battery status retrieval service is executed, and a notification is displayed. Users can choose to disable notifications by turning off the "Allow Notifications" option in the app settings.

The battery status retrieval service is responsible for obtaining and recording the battery status. If a widget is placed on the home screen, the battery status display will be updated accordingly. It runs in the background, so it is important to avoid restricting background execution through power-saving settings. If the app is stopped, the recording of the history will also be stopped, and the battery status display on the widget may not reflect the accurate values.
