Confirmed! Battery life is better IMO... About that in-call volume, I had some issues with it, then I figured it out. Turns out if there is a lot of noise in the background the volume will get higher, if its quiet the volume will be ok. I know this because when I was making a phone on a street in the evening, its was kinda quiet and the volume was normal, but as a car went by me the volume got much higher and then went back to normal after the car passed. So it's not a bud i guess...
As for the rom, it's great, I really like it, fast, responsive. If Daz fixes the mobile data eating the battery, i'd call it a final version...
