ok I got Q... lol I am running shostock3 v.2.1 and AJK v. 1.6 been messing with this for a little while now when I 1st got it all installed I ran it on default profile but battery life wasnt like I expected after reading everything that everyone was saying so I switched it to the battery profile for about a week it got better with life but seemed laggy at times mainly when I unlocked screen and on some games. I have since went to the rav4kar profile been on that for almost 2 weeks now and its amazing how long this thing can last now and it stays fast at the same time.. sorry for all the boring info but my Q is what benefits are there to upgrading to the newer shostock3? Honestly I am a little afraid to touch it now lol its running so smooth and fast and battery is remarkable just dont wanna mess that up just curious if its worth risking my battery life to update it?
