    Default sencha touch app very slow on iPhone Device

    hi ,

    am trying to test my app on iPhone device , i tested it on android device and it works good , and tested it on the iPhone emulator using Xcode and it's extremely fast and reliable ,

    but when i tried it using Ad Hoc on iPhone device it was extremely slow and jerky

    also , swipe lists and buttons clicks are very very slow

    am using PhoneGap + Sencha Touch

    How much do you have rendered at once?

    DOM is the largest performance hit so if you have a lot rendered, the slower things will work and react. A computer can handle it because it's a lot more powerful. A phone or tablet isn't quite powerful yet albeit they are starting to accelerate in getting more powerful.
