I'm not going to update to 4.1.2 if they don't at least let us know they are working on the problem and that they will fix it. I've heard up to 30% battery loss. But on average is 15%. That's still way to much.
Email Samsung about this, let them know we need a fix. I'm sending them emails weekly about this issue. It's just to big of an issue to let it go. It seems allot of people are not taking action. So please, take action and email them, call customer support at least once about the problem. I'm sure Samsung is aware but they won't fix it unless more people complain.
