I agree that kk drains battery on the g2. I got a g flex and honestly have no issues with it whatsoever....its far better than the g2 in my opinion. There is no lag like how the g2 would hiccup scrolling through the stock launcher, the 720p resolution isnt also bad at all, there is no crazy battery drain either. The g flex is a bigger perfected g2 with knock code. Its awesome. Will probably be posting my g2 on swappa shortly.
