I love the JB Sourcery ROM. But one thing I have noticed on 4.4 and 4.5 (I guess 4.2.1 in general) is my battery gets chewed up pretty quick. After about 12 hours I'm down to the 30-40% range. I know most of you will say that is good, but when I was 4.1 ROM's I was easily still above 50-60%, a lot of times above 70% after 12 hours. This of course with light - moderate use.
I'm hitting deep sleep OK now...at least above 80% most of the time, but still not as good as on 4.1.
Is there just something in the 4.2 ROM's that pull the battery down quicker?
