As of now, let me make sure I have allt he information from the first post to the latest one in terms of relevance:
-Juice Defender does not seem to fix this via the workaround (though someone stated that Plus or Ultimate Version can solve this).
-wolfyboy359 and TripleFall says they was trying Battery Defender (no update yet).
-ATT Wifi App is a no-go.
Has anyone tried Battery Defender with results yet?

App description reads:"Automatically disable wifi and data connection after you turning off your screen(with 15~20s latency)" but I had the screen off for 60 seconds and wifi was still active (app was on of course).
: Last night I installed and activated Battery Defender. Here are the results as of a few minutes ago:
With this workaround, should Android OS still be using the batetry the most?
