# Device

The Device API exposes internal information about the device, such as the model and operating system version, along with user information such as unique ids.

This can help you

* Find out the operating system of the device - iOS, Android etc
* Find out app's version so you can send update or update alerts to user
* Find available disk , using which you can alert user to delete data etc
* Find uuid of the phone. This can be useful when you want to register the device on your server. E.g. Uber uses this ID to register the device on the app. So even if you change your sim card on the same device, you cannot create a new account.

### Example <a href="#example" id="example"></a>

```
import { Plugins } from '@capacitor/core';

const { Device } = Plugins;

const info = await Device.getInfo();
console.log(info);

// Example output:
{
  "diskFree": 12228108288,
  "appVersion": "1.0.2",
  "appBuild": "123",
  "osVersion": "11.2",
  "platform": "ios",
  "memUsed": 93851648,
  "battery": -1,
  "diskTotal": 499054952448,
  "model": "iPhone",
  "manufacturer": "Apple",
  "uuid": "84AE7AA1-7000-4696-8A74-4FD588A4A5C7",
  "isVirtual":true
}
