Battery life question and possible Fix?

[Biggdogg76]

Does anyone know if it is recommended that you fix permissions using ROM manager or the advanced setting of the ROM every time you flash a new version of a ROM or do you only do this when you are experiencing problems? I always clear/reset battery stats when I flash a new ROM to try and get accurate battery stats but I am curious if this would help too? There are so many ways to effect battery life it is mind blowing but I'm just wondering if this helps battery life/stats and some other small issues i have encountered and stated in previous posts. I LOVE THIS ROM and I'm only just get started playing with it!!!
