title: Monitor the current going into iPhone or iPad when charging
body: <p>Is there a way to see the levels of current that are going into the iPhone or iPad when it is charging?</p>
  
  <p>I know of some code that allows you to see the level at which the battery is charged but I'd like to be able to see the current that is going into the device when it is charging.
  Does code like this exist?</p>
  
  <p>All I've come across is:</p>
  
  <pre><code>float batteryLevel = [UIDevice currentDevice].batteryLevel;
  UIDeviceBatteryState currentState = [UIDevice currentDevice].batteryState;
  </code></pre>
  
  <p>However, these only tell you the level of the battery or if it's plugged in or not.</p>
