First off I love this new MBP I havent even scratched the graphics power yet and have mostly used it for music (DAW) and surfing. I do have a slight concern. I was using it during a band practice with about 8 plus hours of battery life. I barey used it and had it play a few songs back during rehearsal. The sucker kept going into energy saver so in the middle of session (1.5 hours into it) I set the Energy options to Never. Now of course after a few minutes it would kick into the screen saver but it was fun watching that whilst we jammed about an hour later I noticed my battery life went straight down to 2 plus hours I was puzzled that it drained that much. I guess kicking it into that setting drained it faster? Any thoughts on what happened here? Please share P.s. I still love it!!
