I was about to post a similar post with screenshots. I believe what's going on, for most intents and purposes, is a combination of users confusing aging batteries and a general set of unrealistic expectations for a OEM 1800mah batteries pushing the GSII's horsepower, with a problem specific to the ROM.
I now own five batteries for this device (3 OEM and 2 Anker) and there is a stark difference, not only between the Anker vs OEM, but also between the oldest OEM and the newest. On the whole, this ROM is pushing up on a 10/10 imo.
My last phone (evo shift lol) would last all day with radios on with push sync enabled for Gmail and exchange... With a smaller battery.
There is no winning for me here.. The only way to get through the day is to use ds battery saver to turn off my freaking radios and only have it wake up once every hour. On top of cpu sleeper and exits tweaks...
On touchwiz however, battery life is markedly improved. I give up as bbs and gsam do not show a single thing out of the ordinary... Fml
