ElecTRON Battery
Electron Battery is a 2×2 battery indicator widget. The platform of the RECOGNIZER rises and falls, not to kidnap you for the games, but to indicate your battery level! The lower your battery levels, the lower the platform goes. It also indicates the level numerically. The widget updates approximately once a minute.
