When I have Gsam loaded it give quite a different picture of battery usage. With the native power report it appears to be lumping a lot of things into "display/screen". On Gsam screen is much lower and kernel show just about as much as screen.
Now move to my Acer Iconia A200 tablet with 4.0.3 also and kernel is way down? So is sense on the Rezound using a lot of battery?
