But your awake time is down from 4 hours. Something is apparently still updating itself, using the CPU. It received 101 MB of data. I just looked at mine - it received 333 kb. So wonder what is running in the background. Do you have Google Now enabled? I am hoping someone else can take a look at these shots and pinpoint it better.
Now I went back to the beginning of this thread and I may have missed the OP who said go into
System Settings-->accounts--> Google-->your email account
In there you will see what's sync or trying to sync..I had the browser giving a sync error and I just unchecked it. My guess is it all comes checked with the JB OTA...I didn't even know it was in there..check that out. May not help but you you never know..
