So I decided to go back to TouchWiz and I've noticed that my S6 is really snappy, everything opens super fast and there is no lag what so ever. I noticed that when I was using Nova with the other setup I only had about 350MB of RAM available and once I started using TouchWiz again I have over 700MB of RAM left. And I've noticed battery life is also better. With that said I know most of us haven't been getting the battery life we want out of the S6 or the snappy performance this phone should be giving us and it could all be because of the setup we have on our phones.
