I had to quote these bigass screenshots lol
Is it me or does your standby usage look to be the same as before you flashed the rom?
Also, the time in the 2nd shot is earlier than the first yet the battery stats show a longer timeframe. Have you calibrated your battery recently as it may be overdue?
That's an old screenshot and you can see I get considerably more usage out of it. I was on pandora while browsing(multiple tabs), had adobe open and played angry birds.
Today - during this short while I was in class with the brightness on lowest(lights were off for presentation) and that steep drop in my previous post is after a 1 hour lecture.
