A PhoneGap app can occupy several times the memory size of a native app. Unless it’s a very simple app, this memory will grow in time because web developers don’t have direct control over objects in memory. This can be an issue if your app targets users with high expectations on performance and quality. In iOS 5 Apple offered native integration for Twitter, same was done for Facebook in iOS 6. This is not simply a new feature for convenience, it’s a necessity aiming to reduce the use of web views in native apps because the memory cost of a web view in an app can be several times the normal size of the app. This kills other apps in memory which the user has previously run – not a big issue in itself but next time these apps are run there’s typically a short pause until they restart and the transition is not smooth.
