OK, so I think between ss220, armandov99, and my own experience combined with suggestion by 84guy, I am almost certain I have found the culprit to the android.process.acore recieving large amounts of data.......................
It is Facebook for HTC sense! I dont know what is causing it, but after suddenly having such poor battery performance the last couple days, I tried making each change individually so i could isolate the cause.
At first I thought that it wouldnt be Facebook for HTC sense, as 84guy mentioned becasue I had it set to sync only once every eight hours, so I didnt go there right away
I tied uninstalling each app I had loaded individually while then turning the phone off, and back on and letting it run for a while, and checking my battery usage. The android.process.acore was using data like crazy after each time.
I used ATK and tried killing off individual apps then plugging in to reset battery usage stats, and checking usage. Still had android.process.acore eating away at my battery.
Finally I removed my Facebook for HTC sense account. POOF - No more android.process.acore in my battery usage. I think this makes sense as armandov99 said that the calendar was constantly running for him, and Facebook for HTC sense syncs your events and friends b-day etc. from Facebook.
I again signed in to Facebook for HTC sense, and everything is great. Been off the charger for 6 hours with normal use, and still have 70% battery remaining!
I had been signed in to Facebook for HTC sense ever since picking up my phone, so I dont know what changed, but it had definately gone rouge on my phone.
