no it doesnt and it certainly doesnt feel native either. especially with the latest ios and android os.
So PhoneGap applications are technically "hybrid apps." The WebView portion of the app is native code - but that really is just a technical nuance with no implications for performance (in fact, the performance implications are negative), because it's like claiming that your website is "native" since it runs in a browser (say, Safari) and the browser is written in native code. But the non-native portion of the app is what goes inside the WebView (HTML/CSS/JS).
