I flashed the rom around 3:00 pm today paired with the 1.1 ghz slayher LV kernel and it is now 3:00 am in my current location. It seemed to have much better battery life all throughout the day, until I just picked it up to send a few texts about 20 minutes ago. It was at 50% and suddenly jumped down to 20% in a matter of three texts. I don't really understand why it does this, but I don't seem to be alone with this issue.
I will continue to run it tomorrow and see if I experience good or poor battery life.
Pete, I'm just adding to the feedback here on 6.2 so if you need any more detailed information just PM me and let me know I will try to be as helpful as possible.
ALSO: My battery status does not display the apps that are using the battery. It only displays the system, display, etc. Why is this? I also had this problem with v0.5.
