Mate actually there is a bug. Battery calibration.
I've noticed many roms around have this feature, some kind of auto-calibration script, which is kinda useful. I'll make an example of real life with your rom: 40% battery -> reboot -> battery is now at 54% -> I make a call, battery drains insanely fast, goes down to 37% for just a 2min call (so 40% was correct) -> I connect the phone to a charger -> in less than 10mins goes from 37% to 75%... Simply: WTF??!?
By the way... amazing work! Love your rom.... might be cool trying the dolby mobile.. luv u!!
luv u 2
