توضیحات:

This is an application that displays the temperature of the battery.
The temperature can be measured in increments of 0.1℃.
This app does not have the function to display in the widget or notification field.
This is not a widget, so you can see the change in battery temperature in real time while displaying the screen, not every few seconds or minutes.
This is not a widget, so it doesn't keep displaying the battery temperature when it's not needed, so it doesn't itself raise temperature or drain the battery.
