Yeah agree so far my flagship Androids all perform like a breezeLol.. That's not true when one conscientiously do maintenance by removing unwanted apps and unwanted files..
The lag comes in when you have more and more apps fighting for the limited ram and that it hog cpu resources as well. Other than that, it won't lag.
Have been using Android after ip4 days, no such thing as lag after some time.. Lol..
