Battery Level is a small yet useful widget for Android users. Developed by Penza Software, this free widget allows you to easily monitor your device's battery level, temperature and voltage. The widget is simple to use and can be added to your home screen with just a few clicks.

One of the best features of Battery Level is its ability to show battery usage on click. Simply click on the widget and you will be presented with detailed information about the battery usage. Another great feature is the background color change, which shifts from green to red depending on the battery level. This gives you a quick and easy visual cue of your device's battery status.
