Power Cells Live Wallpaper for Android is designed to give you feedback on your current battery level while presenting a beautiful shimmering backdrop for your home screen. Each cell randomly animates through the colour spectrum, and disappears when touched. Cells then grow back at a rate related to your battery power level. When your battery level is very low all the cells animate around the red spectrum as a warning, and when recharging they shimmer in the green spectrum. You can select from different themes through the wallpapers settings to suit your mood.
