Redraws drive everyone crazy.
But in order to help you, we need some details like Android version, root, ROM, kernel, launcher, total apps installed, free RAM..
If you haven't rooted your phone, I'd suggest you to do it and get rid of the unwanted apps.
If you have root, try changing kernels to find out the one that suits ur ROM.
Also, you can install Greenify to restrict background apps.
You either own a Nexus. or you own nothing
