Hello there, Before I start let me just say I've already read through the similar threads, and tried some of the fixes posted there. However, my phone (Galaxy S Advance, Android 2.3.6) still uses around 80Mb a day on OS Services. I've turned off "Back up my data". I haven't got a Live Wallpaper. The only accounts that sync are my Gmail and Hotmail, besides they have a separate icon in my data manager. If this keeps up I'll be using about 2Gb a month without even doing anything on the phone.
