The battery
read-only property
returns a BatteryManager
which provides information about the system's
battery charge level and whether the device is charging and exposes events that fire
when these parameters change. This interface was introduced in early drafts of the Battery Status API and but has
been replaced with Promise
-based
Navigator.getBattery()
.
Note: The battery
property has been removed in favor of the standard
Navigator.getBattery()
method, which returns a
battery Promise
.
Syntax
var battery = navigator.battery;
