import DeviceBattery from 'react-native-device-battery';

// get the battery level

DeviceBattery.getBatteryLevel().then(level => {

  console.log(level); // between 0 and 1

});

// check if the device is charging

DeviceBattery.isCharging().then(isCharging => {

  console.log(isCharging) // true or false

});

// as a listener

var onBatteryStateChanged = (state) => {

  console.log(state) // {level: 0.95, charging: true}

};

// to attach a listener

DeviceBattery.addListener(onBatteryStateChanged);

// to remove a listener

DeviceBattery.removeListener(onBatteryStateChanged);

```
