title: Get WP7 battery telemetry data?
body: <p>I'm looking for a way to get the current battery telemetry under Windows Phone 7. The closest part of the framework looks like <code>Microsoft.Phone.Info.DeviceExtendedProperties.GetValue()</code> but it seems you can only query the device info (model, serial) and the current memory consumption.</p>
  
  <p>Is battery data inaccessible under this iteration of WP7 SDK, or am I just missing something?</p>
