Forum Thread: Phone Is Sluggish After Rooting

Try a couple of things:

First, goto Settings > Developer Options > Change "Window animation scale", "Transition animation scale", and "Animator duration scale" to 0.5x (or even 0 for super snappy quickness). It should kick in right away, but I'd recommend a reboot.

Second, goto Settings > Battery > Check to see if "Android System" is being a resource hog. In most cases, anything above 40-50% usage is too high. If yours is high, run through the steps I posted here.

Thanks for the tips. I did both things and added some of those build.prop hacks, my phone is flying!

Nice! Glad it all worked.
