Battery Ace

Battery Ace is a powerful Chrome extension designed to keep you informed about your device's battery status at all times. It offers three distinct widget modes — level, time left, and temperature — each presented with high-quality, resizable graphics and numerical battery percentages. Users can choose from several widget styles and configure custom color limits to personalize their experience.

The app includes advanced features such as discharge and charge time predictions, graphical history of battery usage, battery details like temperature and voltage, and customizable battery level warnings. Additionally, Battery Ace supports Dark Mode for a comfortable visual experience. It's optimized to be lightweight, ensuring minimal battery consumption. For optimal performance, users are advised to avoid task killers or power-saving features that might interfere with operation. Note that moving the app to an SD card disables widget functionality due to system limitations.
