    window.navigator.battery Redirect 1

    Deprecated
    This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

    The battery read-only property returns a BatteryManagerprovides information about the system's battery charge level; provides also some new events you can handle to monitor the battery status. This implements the Battery Status API; see that documentation for additional details, a guide to using the API, and sample code.

    The battery property is deprecated and has been replaced by a Navigator.getBattery() method returning a battery Promise. Its support is still partial though.

    Syntax

    var battery = navigator.battery;
