How to solve the problem of mobile animation stutter caused by code?

would you please quote jquery.js, to run the code? it"s OK on Xiaomi phone. There are obvious stutters on Huawei Meizu and vivo, iphoneSE can, and iphone6s have obvious stutters. There must be this kind of problem in some untested models. I don"t know what the problem is. Thank you for your help.
