### Usage Guidelines<a name="section12620311012"></a>

**Obtaining the battery level**

Use the JavaScript API to obtain the battery level.

The sample code is as follows:

```
battery.getStatus({
  success: function(data) {
    console.log('success get battery level:' + data.level);
  },
  fail: function(data, code) {
    console.log('fail to get battery level code:' + code + ', data: ' + data);
  },
});
```
