In my experience, although the phone is still blazing fast on its own, I did notice less lag when returning back to the home screen (sometimes it would have to redraw... Could be placebo) and while browsing the web using Chrome (definitely not placebo). As for battery life, I have not noticed any decrease at all while having it active. I am using a rooted RAZR MAXX HD with stock ROM.
How have everyone else's experiences been with lag and battery life while using Seeder?
