chargingTime

Indicates the amount of time, in seconds, that remain until the battery is fully charged.

Even if the time returned is precise to the second, browsers round them to a higher interval (typically to the closest 15 minutes) for privacy reasons.

Syntax

var time = navigator.battery.chargingTime

On return, time is the remaining time in seconds until the battery, which is a BatteryManager object, is fully charged, or 0 if the battery is already fully charged. If the battery is currently discharging, this value is Infinity.

Example

HTML Content

<div id="chargingTime">(charging time unknown)</div>

JavaScript Content

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

var time = battery.chargingTime;

document.querySelector('#chargingTime').textContent = battery.chargingTime;

});
