 * Maps Android [BatteryManager.EXTRA_STATUS] and [BatteryManager.EXTRA_PLUGGED] to JS.
 *
 * [BatteryManager.BATTERY_STATUS_NOT_CHARGING] is reported when the battery is full, when power is
 * connected but charging is paused (e.g. battery protection at 80%), or in other cases.
 * When [plugged] is non-zero, we expose [BatteryModule.BatteryState.NOT_CHARGING] so
 * [BatteryManager.BATTERY_STATUS_DISCHARGING] remains the only path to [BatteryModule.BatteryState.UNPLUGGED].
