lancelot916: Can you clarify?
The default battery gauge is very ... misleading. It will look like it's more charged when other "numerical" indicators indicate something lower (I've seen the battery gauge to look about half full when the phone is at 20-30%).
Are you talking about your LED indicator going blue when a numerical indicator says 78%?
I don't think I've had to recalibrate my battery readings (using Power Control Plus, which really needs to fix their 4G button so it works with the Epic).
