I looked at that sample but I don't think that solves this problem. In another forum thread "Mobile Page Caching" it sounds like rendered Kendo mobile pages never get destroyed or removed from memory so I followed the recommendation there and used .remove() on the elements and recreated them before rendering the list view. That helped a great deal though I still have one spot that seems to slow down, but not nearly at the pace it did before. So I doubt that my work around is the best, but it's working better than before. It sure seems like I should not have to do this kind of stuff to make Kendo mobile work.
