Flat Battery Live Wallpaper is an Android app developed by Jiří Sýkora that shows your current battery status in percentage with a cool material design. This app eliminates the need for battery savers, widgets, and monitors by informing you about your battery status directly on your wallpaper. The live wallpaper takes up minimal battery, as it is updated only when the battery level changes.

One of the best features of Flat Battery Live Wallpaper is the ability to create your own HD wallpapers with customizable colors and skins. The app offers six cool skins, including a "DECREASING" bar, "SIMPLE", "HALF NUMBER", "CIRCLE", "HALF CIRCLE", and "MATERIAL DESIGN". Each skin has the ability to change colors, stamp effects, and long shadows. The default skin is free, and the other skins are available for purchase in-app.

Overall, Flat Battery Live Wallpaper is a great choice for those who want a minimalist yet stylish way to monitor their battery status. If you have any problems or ideas, you can contact the developer via email. However, it is important to note that the app may not work properly with AVG Antivirus, and it is recommended to remove the antivirus program before using Flat Battery Live Wallpaper.
