HTC One is constantly syncing even though Auto-sync is turned off...Any Ideas?

And the crazy part about it is I have no idea what it is syncing

I had to turn off Google + on mine. It stopped syncing.

Instead of just generally disabling sync, go to Settings > Accounts & sync and check them individually. If you've already done that then I got nothin'.
