Very true. Now I am also at a bit of a disadvantage on this one as I do not have the Samsung myself, but am going based on what I see on some friends phones, as well as experience with the Motorola phones. I think they do this on purpose though as each update they promise better battery life and then it is terrible right out of the box and if a week later it is back to 90% most people do not notice that difference, but are so happy it is better then right after the update they live with it.
The other thing I notice on these updates and we all do it, is once it is updated you are playing with your phone more and more looking for new features or trying to find features they remove, or trying to figure something out and that uses tons of battery as well. Usually after about a week or so we settle down on that part too and the battery starts getting better so we may be doing it to ourselves by doing that as the android OS will learn when to shut things off or leave them on etc... and if we are playing with things turning them on, it will learn to keep them on and after we stop the OS realizes it is not needed and rewrites the order list.
