Fix for animation lag..change power settings

[Bishop_the_android]

I was getting bad animation lag, on beta 2, when opening and closing edge panel, switching apps etc. 

I noticed the phone was on "medium power saving" mode and just changed to optimized and the animation is now infinitely better and smooth as butter!
