| Property | Type | Description |

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");
});
