The thing is if you're using your Tablet for the internet i.e browsing or video. Then this isn't viableMy best tip for you is GreenPower free.
That app is awesome to control wifi power.
I have mine set to 2 mins on each 1 hour, so now it is actually the screen using the battery, instead of only the wifi
I also use it on my phone with the same results.
And of course root and CleanRom2.3 is awesome together with Clemsyn kernel
