Yup. Display brightness was set to auto, screen timeout the same 30sec, and all configurable sync set to as close as I could make them.
There was one difference though. The Captivate was running a leaked (but otherwise unmodified) Gingerbread release, while the Thrill was stock FROYO. GB isn't worth 30% battery though.
In my tests between the 2 phones, I noticed 2 major "elephant-in-the-room" differences regarding battery life. 1) With auto-brightness turned on, the Thrill measured consistently higher brightness in the same light as the Captivate. 2) The Thrill let programs run in the background much longer than the Captivate. I was consistently killing 3-4 apps manually with the task killer versus 1-2 with the Captivate.
