The BatteryManager object should have a readonly property called level. The level attribute must be set to 0 if the system's battery is depleted and the system is about to be suspended, and to 1.0 if the battery is full, the implementation is unable to report the battery's level, or there is no battery attached to the system.
Mulitple Batteries. level attribute. The level attribute can be set to the average of the levels of batteries of same capacity, or the weighted average of the battery level attributes for batteries of different capacities.
Example:
// We get the initial value when the promise resolves ...
navigator.getBattery().then(function(battery) {
console.log(battery.level);
// ... and any subsequent updates.
battery.onlevelchange = function()
});
Example 2 (Alternative):
navigator.getBattery().then(function(battery) {
console.log(battery.level);
battery.addEventListener('levelchange', function() { console.log(this.level); }
);
});
