PS: Is there an app which shows the activity of the different cores?
I would guess that there is some app that is running in the background that is causing such high CPU usage. If my tablet is not being used, it stays in Deep Sleep most of the time.
If you would reset to factory defaults, I'm sure you'd go back to "normal" CPU usage... It would be a good test regardless (just back everything up, just in case).

Start by just rebooting. Then only run the cpuspy app to check and reset counters.
Next, leave it for a while and see what the stats say afterwards. If it's normal it's one of the apps he normally uses that is to blame and doesn't shut down properly. Just like my OpenGarden app.
What browser are you using? Does your battery get hot? There were some reports that stock-based browsers were having some issues recently.
I was normally getting around 15%/hr drain, which would be probably around yours. After the last update Battery Monitor Widget is going crazy with the stats, but I guess the drain stays quite the same, so around 7 hrs browsing.
I know it may not be the solution for every-day use if you need flash, but give Chrome a try for a full battery cycle and see what's the difference.
What is everyone getting as far as mA drain? A few days ago I received my replacement Infinity, and its battery life seems terrible compared to the first one, about 4 hours screen on time in balanced mode from only web browsing. I got 7 hours once, but there was a good amount of video streaming and I know the Tegra 3 is much more efficient while viewing video so I dont really count that.
It looks like I'm getting -287 idling on the home screen and -993mA during web browsing. Just want to figure out if the battery is still calibrating, I have a rouge app or something's wrong with my tablet.
"I would love" to not have to re-root and reload all my apps, too bad unlocking voids the warranty, thus no nandroid. Even with Titanium it is a PIA. Your reply of wiping is about as good a reply that Best Buy Geek Squad or the Manufacturer gives. Maybe a "not-thank you" button would be appropiate as well.
The other suggestions on here (like the Auto Airplane Mode App) are helpful and the reason why XDA is better.
