Answer 1

The battery property has been removed in favor of the standard Navigator.getBattery() method, which returns a battery Promise. Its support is still partial though.

Given that, you can run the code like this:

navigator.getBattery().then(function(battery){
alert('Battery: ' + battery.level * 100 + '%');
if(battery.charging) {
   alert('Battery Status: Charging');
} else {
  alert('Battery Status: Power cable not connected.');
}
});

Hope this helps.
