This can have the effect of making your app feel slow and unresponsive. Avoiding this delay is one of the most important ways of improving your app's perceived performance. For more information on the tap delay, see [300ms tap delay, gone away](https://developers.google.com/web/updates/2013/12/300ms-tap-delay-gone-away) on the Google Developer site. +* **Click vs. Touch** -Most Android versions no longer impose this delay, but iOS by default still does. For iOS, using [WkWebView](https://github.com/apache/cordova-plugin-wkwebview-engine) instead of the default UIWebView gets rid of this delay. For both Android and iOS, you must ensure that your viewport meta tag has at least `width=device-width`, or you will still have the tap delay. If you need to support older devices (Android 4.4 or iOS 8), consider a polyfill such as [FastClick](https://github.com/ftlabs/fastclick), or using `touchstart` and `touchend` instead of `click`. + Many devices impose a 300ms delay on click events in order to distinguish between a tap and tap-to-zoom gesture.

A desktop app that slurps down 500 rows of JSON data, every 30 seconds, will be both slower on a mobile device as well as a battery hog. Keep in mind that Cordova apps have multiple ways to persist data in the app (LocalStorage and the file system for example). Cache that data locally and be aware of the amount of data you are sending back and forth. This is an especially important consideration when your application is connected over a cellular network. + As of 2015, most Android and iOS devices no longer imposes the delay. For both Android and iOS, ensure that your viewport meta tag has set the `width=device-width` value or you will still have the tap delay. Review Comment: I feel most of this content is no longer needed, but the emphasize the significance on the viewport meta tag `width=device-width` is still important as it can have advese affect without it. -- This is an automated message from the Apache Git Service.
