Alright, so this app was released right around the time where I upgraded to my Note II and I remember how it brought to my attention how Snapdragons seemed to be more power efficient that my Exynos. I always wondered if the guru actually worked. I am just starting to test it now, but I was wondering if anyone else had already tried. I'll post my own results in a week or so, but I'm curious to see other people's results. 2 day battery life would be awesome...
