E.g. the accordion demo [here](http://getbootstrap.com/javascript/) is jerky (or choppy). I've tried Firefox & Chrome on Nexus 5, Safari & Chrome on iPad Air 2. Both devices have good specs when it comes to MHz/RAM. \r\n\r\nI'm wondering if this is a limitation of mobile devices. Is there some small tweak that can alleviate it ?\r\n\r\nSome related discussion:\r\n- [Proper way to optimize CSS 3 animations for iOS/Mobile Safari?](http://stackoverflow.com/q/6481894/)\r\n- [Why is jQuery UI accordion open/close animation so choppy?](http://stackoverflow.com/q/15501060/)\r\n- [jQuery Jerky slideUp and slideDown With Twitter Bootstrap Well](http://blog.markstarkman.com/blog/2013/07/25/jquery-jerky-slideup-and-slidedown-with-twitter-bootstrap-well/)\r\n- [Two things that cause jQuery jerky animations\r\n](http://jaredheinrichs.com/two-things-that-cause-jquery-jerky-animations.html)"},"comment":{"url":"https://api.github.com/repos/twbs/bootstrap/issues/comments/72578190","html_url":"https://github.com/twbs/bootstrap/issues/15723#issuecomment-72578190","issue_url":"https://api.github.com/repos/twbs/bootstrap/issues/15723","id":72578190,"user":{"login":"mdo","id":98681,"avatar_url":"https://avatars.githubusercontent.com/u/98681?v=3","gravatar_id":"","url":"https://api.github.com/users/mdo","html_url":"https://github.com/mdo","followers_url":"https://api.github.com/users/mdo/followers","following_url":"https://api.github.com/users/mdo/following{/other_user}","gists_url":"https://api.github.com/users/mdo/gists{/gist_id}","starred_url":"https://api.github.com/users/mdo/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mdo/subscriptions","organizations_url":"https://api.github.com/users/mdo/orgs","repos_url":"https://api.github.com/users/mdo/repos","events_url":"https://api.github.com/users/mdo/events{/privacy}","received_events_url":"https://api.github.com/users/mdo/received_events","type":"User","site_admin":true},"created_at":"2015-02-03T01:59:28Z","updated_at":"2015-02-03T01:59:28Z","body":"Yeah, there's not much else we can do other than what @cvrebert mentioned."}}
