Properties

The event callback doesn't receive any event objects, but properties can be read from the BatteryManager object received from the navigator.getBattery method.

Property Type Description
BatteryManager.dischargingTime double (float) the remaining time in seconds until the system's battery is completely discharged and the system is about to be suspended. Returns positive infinity if the battery is charging, if the implementation is unable to report the remaining discharging time, or if there is no battery attached to the system. Read only.

Example

navigator.getBattery().then(function(battery) {

  console.log("Battery discharging time: " + battery.dischargingTime + " seconds");

  battery.addEventListener('dischargingtimechange', function() {
    console.log("Battery discharging time: " + battery.dischargingTime + " seconds");
  });

});
