最近做微信开发，发现页面在 iOS 上非常流畅，但在 Android 上却会出现卡顿的现象，换了几台安卓机都有。
回复内容：
为啥我在做微信开发的时候，HTML5在Android端上很流畅，在iOS上却有点卡呢？所以我猜和具体机器有关系，和系统关系不大，所以就别来黑了吧 是黑？
android上并不比ios卡，你这种是不是换台手机好点？
毕竟nexus one和iphone6是没法比的……
顺便告诉你千万别用jquery，除非你想卡出翔 让你们公司换个贵的测试机器 iOS的微信webview我记得默认是调用safari的，配合iPhone的性能，所以肯定不会差。 安卓就比较复杂了，如果不是原生安卓，
webview可能会很老旧，安卓微信的webview从UA上看似乎是qq浏览器的内核，这也有点蛋疼。
还得看手机的具体配置。 因为苹果的硬件性能还是不错的,硬件固定和系统封闭导致浏览器优化也好做一些
安卓最出名的是什么,伴随着销量大和适应性强而来的最出名的特点就是碎片化了,各种为了成本压榨的硬件采购,自定义的系统配置,开放的软件开发,让问题出现的几率放大几万倍.
如果你要兼容安卓开发,最好不要想做太复杂的效果,就联想下pc端兼容ie6的做法. 乔布斯当年推出iPhone和iPad时就决心彻底抛弃Adobe的Flash，当时还和Adobe掐了起来，最后发表了对Flash的一些看法一文。
他们选择采用HTML5，认为HTML5
处在技术的春天，并一直在对其做优化，希望HTML5成为下一匹能够一直不停奔跑的马，iPhone4出来的时候就他们声称全世界的智能手机对HTML5支持最好的是iPhone。。。
安卓的话，不是很清楚。感觉大部分安卓机还是比iOS卡。。毕竟iOS专为苹果的设备打造。。。安卓机的配置也层次不齐。
当然可能跟语言也有关吧，但是我对iOS的语言不了解，不敢乱说。 因为安卓版微信的webview使用了牛逼的“QQ浏览器x5内核” 做过不少移动端的小东西了，android卡还是卡在动画多的时候，这一点说白了还是android的内存回收做的不够给力，渲染这部分我没读过内部实现不敢说，不过这个层级上应该不差多少。 因为Adobe和苹果撕逼了，就这么简单～～
