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.chargingTime double (float) The remaining time in seconds until the system's battery is fully charged. Returns 0 if the battery is fully charged. Returns positive infinity, if the battery is discharging or if the implementation is unable to report the remaining charging time. Read only.

Example

navigator.getBattery().then(function(battery) {
  console.log("Battery charging time: " + battery.chargingTime + " seconds");
  battery.addEventListener('chargingtimechange', function() {
    console.log("Battery charging time: " + battery.chargingTime + " seconds");
  });
});
